1) The document proposes an alternative cosmological model where dark matter and dark energy are described as forms of ether, analogous to Mach's principle of inertia.
2) In this model, dark matter arises from the QCD vacuum or "sea" of quark-antiquark pairs and gluons at the confinement scale, while dark energy corresponds to the zero-point energy of the QCD vacuum.
3) The model aims to replace the standard LambdaCDM model, treating the expanding universe as a dynamically stable "biking" Einstein universe where the running cosmological constant compensates for the effect of gravity at all epochs.

1) The document outlines key concepts from Einstein's theory of special relativity including reference frames, the Michelson-Morley experiment, postulates of relativity, Lorentz transformations, length contraction and time dilation.
2) It discusses experimental evidence for concepts like time dilation from observations of muon decay lifetimes and provides equations for length contraction, time dilation, velocity addition and relativistic mass.
3) The twin paradox is introduced as a thought experiment exploring time dilation between twins where one takes a high speed journey into space and back while the other remains on Earth. Accelerations are identified as the resolution for why the traveling twin ages less.

1. Isaac Newton conceived of time as absolute and flowing uniformly, an idea that was later disproven by Einstein's theory of relativity.
2. Einstein's special theory of relativity established that the laws of physics are the same in all inertial frames of reference and that the speed of light is constant, independent of the motion of the observer.
3. As a result of Einstein's theory, time is shown to flow at different rates for observers in different reference frames, as demonstrated by the fact that clocks moving at high speeds are measured to tick slower than identical clocks at rest.

Elaborato Luca Rapacchiani

The document discusses Maxwell's laws of electromagnetism and their implications. It covers Maxwell's four equations describing electric and magnetic fields and predicting electromagnetic waves. It describes Hertz's 1887 experiment that experimentally confirmed the existence of electromagnetic waves, using an apparatus to generate oscillations and a receiver to detect the waves. It discusses how Maxwell's laws and the discovery of electromagnetic waves led to a crisis of the Cartesian mechanical worldview and the acceptance of action at a distance and field concepts in physics.

gravitywaves

1) The document summarizes the 100-year history of gravitational wave detection, from Einstein's theory of general relativity predicting their existence to the recent direct detection by the LIGO experiment.
2) It describes how LIGO uses laser interferometry to extremely sensitively measure tiny distortions in spacetime caused by passing gravitational waves.
3) The first detected gravitational waves in 2015 matched predictions for the inspiral and merger of two black holes, with the signal analyzed to determine properties of the black holes such as their masses.

Spooky action from a distance

The document discusses the GRID Extra Dimensions Theory, which proposes that:
- Space and time are quantized into discrete units called quantum cells around the size of the Planck length.
- New non-local dimensions called the GRID exist between these quantum cells and are responsible for quantum phenomena like entanglement.
- These extra dimensions allow for instantaneous "spooky action at a distance" by enabling immediate signaling between quantum cells, bypassing the speed of light.

Einstein

This document provides background information on the development of modern physics leading up to Einstein's theory of special relativity in 1905. It discusses the failures of classical physics to explain new experimental findings, particularly regarding light and the Michelson-Morley experiment. It then summarizes Einstein's two postulates of special relativity and some of the theory's key implications, such as time dilation and length contraction. The document also briefly outlines some experiments that tested and confirmed predictions of special relativity.

PART II.3 - Modern Physics

1) The document discusses the classical theory of electromagnetic radiation confined within an isothermal enclosure and the discrepancies with experimental observations.
2) It analyzes the temperature dependence of the energy density and pressure of the radiation using thermodynamic considerations.
3) This leads to the derivation of the Stefan-Boltzmann law relating the emissive power of a black body to the fourth power of its temperature.

The britannica guide to relativity and quantum mechanics (physics explained)

This document provides an introduction to the key concepts in relativity and quantum mechanics. It summarizes that relativity was developed to explain the constant speed of light, with Einstein's special theory published in 1905 and his general theory in 1915. Quantum mechanics arose from Max Planck's work on blackbody radiation in 1900. The introduction outlines some of the unusual predictions of both theories, such as time dilation, curved spacetime, wave-particle duality of matter, and Heisenberg's uncertainty principle. It also notes the theories have been confirmed experimentally and transformed fields like cosmology, particle physics, and technology.

PART II.1 - Modern Physics

1) The document provides an overview of the contents of Part II of a slideshow on modern physics, which covers topics such as charge and current densities, electromagnetic induction, Maxwell's equations, special relativity, tensors, blackbody radiation, photons, electrons, scattering problems, and waves.
2) It aims to provide a brief yet modern review of foundational concepts in electromagnetism and set the stage for introducing special relativity, quantum mechanics, and matter waves for undergraduate students.
3) The overview highlights that succeeding chapters will develop tensor formulations of electromagnetism and special relativity from first principles before discussing applications like blackbody radiation and early quantum models.

THE KUYPERS EFFECT: ANGULARMOMENTUM CONSERVATION IMPLIES GLOBAL C IN GRAVITY

THE KUYPERS EFFECT: ANGULARMOMENTUM CONSERVATION IMPLIES GLOBAL C IN GRAVITYInternational Journal of Technical Research & Application

A young astronomer’s by now ten years old
results are re-told and put in perspective. The implications are
far-reaching. Angular-momentum shows its clout not only in
quantum mechanics where this is well known, but is also a
major player in the space-time theory of the equivalence
principle and its ramifications. In general relativity, its
fundamental role was largely neglected for the better part of a
century. A children’s device – a friction-free rotating bicycle
wheel suspended from its hub that can be lowered and pulled
up reversibly – serves as an eye-opener. The consequences are
embarrassingly far-reaching in reviving Einstein’s original
dreamCondensed Geometry II(2)

This document presents new ideas in loop quantum gravity, including:
1. Deriving a relationship between time and vorticity using wavefunction continuity.
2. Introducing a new "Eikonal constraint" and showing how it removes acausality by gauging time to light cones.
3. Proposing a new form of the Hamiltonian constraint in the style of the Dirac equation, which reduces state fuzziness in line with Penrose's ideas.

Relativity theory project & albert einsten

Albert Einstein was a German-born theoretical physicist who developed the theory of relativity, one of the pillars of modern physics. He was born in 1879 in Germany and died in 1955 in the United States. He is best known for his mass-energy equivalence formula E=mc2, which has been called the world's most famous equation. The document provides background on Einstein's life and work, and summarizes his theories of special relativity, which describes physics at high speeds, and general relativity, which proposes that gravity results from the curvature of spacetime.

Dark universe and quantum vacuum

Dark universe and quantum vacuumLaboratoire de recherche sur les sciences de la matière (LARSIM CEA-Saclay)

1) The document discusses the emergent perspective of gravity, which views gravity as arising from entropy balance rather than directly coupling to energy density.
2) In this perspective, dark energy in the form of a cosmological constant arises naturally as an integration constant, with its smallness due to a near-symmetry.
3) The document proposes that dark matter and dark energy could both arise as components of the quantum vacuum rather than being associated with non-vacuum matter.Theory of Relativity

The document provides background information on Einstein's special theory of relativity. It discusses the two postulates of special relativity: 1) the principle of relativity, and 2) the constancy of the speed of light. It then summarizes some key consequences of special relativity, including time dilation, length contraction, relativistic Doppler effect, relativistic mass, mass-energy equivalence, and Lorentz transformations. Examples are provided to demonstrate calculations for these various consequences.

PART VII.1 - Quantum Electrodynamics

The document discusses the development of quantum electrodynamics (QED) from its origins in Dirac's 1927 paper on the quantum theory of radiation. It provides an overview of the key topics covered in the subsequent chapters, including particles and fields, quantization of the electromagnetic field, Feynman diagrams, and renormalization in QED. The goal is to show how electrons and photons interact using quantum field theory by representing particles as excitations of underlying fields and developing perturbative techniques to calculate processes like scattering and radiation.

General Relativity and Cosmology

1) General Relativity abolished the concept of absolute space and time, showing that inertial and gravitational mass are equivalent and that acceleration and gravity are indistinguishable (Equivalence Principle).
2) The Cosmological Principle states that the universe looks the same from any location (isotropic and homogeneous), supporting the Big Bang theory of an expanding universe.
3) Black holes are predicted by General Relativity as regions where spacetime curvature becomes infinite, and their existence is supported by observations like gravitational lensing.

Special Relativity

This document summarizes key concepts from a presentation on special and general relativity:
1) Special relativity is based on two postulates - the laws of physics are the same in all inertial frames, and the speed of light is constant. This leads to time dilation and length contraction.
2) The twin paradox is resolved by recognizing that only inertial frames can apply Lorentz transformations - the traveling twin accelerates so experiences more time.
3) General relativity extends these ideas to frames with gravity by proposing spacetime is curved by mass-energy. This predicts bending of light and gravitational lensing.

The classical mechanics of the special theory of [autosaved]

1) The document discusses the basic postulates of Einstein's special theory of relativity, which were formulated to resolve inconsistencies between Newtonian mechanics and Maxwell's electromagnetic theory regarding the speed of light being constant.
2) It introduces the Lorentz transformations, which relate the spacetime coordinates between two inertial frames in relative motion.
3) The transformations show that time is relative between frames and leads to effects like time dilation, where moving clocks are measured to tick slower than stationary ones.

This document provides an overview of Einstein's Special Theory of Relativity. It begins by defining frames of reference and discussing the Michelson-Morley experiment, which found that the speed of light is constant regardless of the observer's motion. It then outlines Einstein's two postulates of special relativity: 1) the laws of physics are the same in all inertial frames; and 2) the speed of light in a vacuum is the same for all observers, regardless of their motion. The document concludes by deriving the Lorentz transformations, which describe how space and time are related for observers in different inertial frames of reference according to special relativity.

A unification of gravity with electromagnetism and quantum

It is known that there is an incompatibility issue between general relativity and quantum mechanics. This paper shows that it is possible to resolve the conflict by deriving gravitational acceleration using a generalized fundamental equation in quantum mechanics that governs the motion of all particles (bosons and fermions). The new theory of gravity makes predictions at the cosmic scale which can be easily verified using existing astrophysics data where general relativity failed to do. It can restore Newtonian gravity as a low speed, quasi-static limit and Einstein’s general relativity as the classical limit at the macroscopic scale. The later includes restoring general relativity’s key concept, the metric tensor and its key equation, the geodesic equation. Curved spacetime is just the manifestation of the quantum motion equation, rather than being the cause of gravity. The new theory makes almost the same predictions as Einstein’s general relativity on gravitational time dilation, gravitational light bending, the extra precession of the perihelion of Mercury, and gravitational waves where the small differences between the two theories are beyond the power of any existing apparatus to detect.

Physics 2 (Modern Physics)

This document discusses the key branches and concepts of modern physics. It begins by outlining the objectives of becoming familiar with modern physics, stating the postulates of special relativity, and differentiating between inertial and non-inertial reference frames. The main branches of modern physics discussed are atomic and nuclear physics, quantum physics, relativistic physics, solid state physics, and plasma physics. Special relativity introduced ideas like time dilation, length contraction, and mass increase that defy common sense. The general theory of relativity further unified these ideas and proposed gravity is a manifestation of curved spacetime due to mass-energy and momentum.

Special relativity

This document discusses the key principles of special relativity, including:
1) The postulates of relativity state that the laws of physics are the same in all inertial reference frames, and that the speed of light has the same value in all reference frames.
2) Consequences of relativity include that there is no absolute length, time, or simultaneity between reference frames. Mass increases and mass and energy are equivalent based on the formula E=mc^2.
3) Time dilation describes how moving clocks run slower than stationary clocks by a factor of gamma, as demonstrated through experiments with muons.

Part IV - Quantum Fields

The document summarizes key concepts from quantum mechanics and symmetries. It states that physical states are represented by rays in a Hilbert space, with observables represented by Hermitian operators. The probability of measuring a state is given by the inner product of the state vectors. Symmetries are represented by either unitary or antiunitary operators on the Hilbert space. Symmetries that can be continuously connected to the identity must be represented by unitary operators. Symmetries form a group, with transformations combining according to the group multiplication rule.

Ch28 special relativity 3 05 2013

1) An event is a physical happening that occurs at a specific place and time, as recorded by observers using reference frames consisting of coordinate systems and clocks at rest relative to the frames.
2) Special relativity has two postulates: 1) the laws of physics are the same in all inertial reference frames, and 2) the speed of light has the same value in all inertial frames regardless of the motion of the light source or observer.
3) Time dilation occurs such that clocks in motion run slower than clocks at rest, as observed from another frame, with the time interval between ticks increasing with the relative velocity between frames. Proper time is the time interval measured in the frame at rest with the clock

Extra_Dimension.ppt

Extra dimensions beyond the usual 3 dimensions are motivated by theories of grand unification and string theory. If extra dimensions exist, they would appear as Kaluza-Klein towers of increasingly massive copies of standard model particles. Some theories propose our universe is confined to a 3D brane embedded in higher dimensions accessible only to gravity. Large or warped extra dimensions could lower the true Planck scale to within reach of experiments like the LHC, solving the hierarchy problem and providing a test of theories of quantum gravity.

Anti-Universe And Emergent Gravity and the Dark Universe

Recent theoretical progress indicates that spacetime and gravity emerge together from the entanglement structure of an underlying microscopic theory. These ideas are best understood in Anti-de Sitter space, where they rely on the area law for entanglement entropy. The extension to de Sitter space requires taking into account the entropy and temperature associated with the cosmological horizon. Using insights from string theory, black hole physics and quantum information theory we argue that the positive dark energy leads to a thermal volume law contribution to the entropy that overtakes the area law precisely at the cosmological horizon. Due to the competition between area and volume law entanglement the microscopic de Sitter states do not thermalise at sub-Hubble scales: they exhibit memory effects in the form of an entropy displacement caused by matter. The emergent laws of gravity contain an additional ‘dark’ gravitational force describing the ‘elastic’ response due to the entropy displacement. We derive an estimate of the strength of this extra force in terms of the baryonic mass, Newton’s constant and the Hubble acceleration scale a0 = cH0, and provide evidence for the fact that this additional ‘dark gravity force’ explains the observed phenomena in galaxies and clusters currently attributed to dark matter.

Short Review of the Unitary Quantum Theory

The paper proposes a model of a unitary quantum field theory where the particle is represented as a wave packet. The frequency dispersion equation is chosen so that the packet periodically appears and disappears without changing its form. The envelope of the process is identified with a conventional wave function. Equation of such a field is nonlinear and relativistically invariant. With proper adjustments, they are reduced to Dirac, Schroedinger and Hamilton-Jacobi equations. A number of new experimental effects are predicted both for high and low energies.

Bp4301373380

This document summarizes an article that proposes an alternative explanation for dark energy and dark matter based on a modified theory of gravity. It begins by providing background on dark matter and dark energy in standard cosmology and the evidence that supports their existence. It then outlines the proposed alternative theory, which modifies Einstein's field equations by adding a function of the Ricci scalar. This introduces new curvature terms that could potentially drive accelerated expansion, providing an alternative to dark energy. The theory aims to match observations without requiring dark matter or energy, but reduces to general relativity in the solar system scale where it has been tightly tested.

The generalization of the Periodic table. The "Periodic table" of "dark matter"

The thesis is: the “periodic table” of “dark matter” is equivalent to the standard periodic table of the visible matter being entangled. Thus, it is to consist of all possible entangled states of the atoms of chemical elements as quantum systems. In other words, an atom of any chemical element and as a quantum system, i.e. as a wave function, should be represented as a non-orthogonal in general (i.e. entangled) subspace of the separable complex Hilbert space relevant to the system to which the atom at issue is related as a true part of it. The paper follows previous publications of mine stating that “dark matter” and “dark energy” are projections of arbitrarily entangled states on the cognitive “screen” of Einstein’s “Mach’s principle” in general relativity postulating that gravitational field can be generated only by mass or energy.

The Gravitational Spacecraft

The document describes a proposed Gravitational Spacecraft that could change space flight. It summarizes that electromagnetic fields can reduce, invert, or intensify gravitational forces by controlling gravitational mass. This allows concepts like a Gravitational Spacecraft that could have unusual trajectories without inertial impacts, as well as a Gravitational Motor that converts gravitational energy into rotation or electricity for free energy generation. Key devices mentioned are Gravity Control Cells and a Quantum Transceiver for communications.

Quantization of photonic energy and photonic wave length

The document proposes that if space is quantized at the Planck length, then photonic energy and wavelength must also be quantized. It suggests that future experiments could detect these quantization levels in cosmic radiation or particle collisions. It also puts forward a "grid dimensions" theory that proposes extra non-local dimensions between Planck length pieces of space that could explain quantum non-local effects like entanglement. Key equations presented quantify proposed quantized limits for momentum, mass, velocity of particles if space-time is quantized.

This document describes a scientific work that proposes a new method for converting vacuum energy into classical mechanical energy. It begins with background on the philosophical differences between classical electrodynamics and relativity theory regarding the propagation speed of electromagnetic fields. It then presents a theoretical model based on quantum mechanics that describes vacuum energy as electromagnetic zero-point oscillations. Several experiments are described that attempt to convert this vacuum energy into rotational motion using an electrostatic rotor device, with some evidence of excess energy production beyond what can be explained by conventional sources. Future work is proposed to further develop this method into potentially useful applications if proven valid.

News from Quantum Gravity Phenomenology

General Relativity is inconsistent with quantum theory which
leaves our understanding of nature incomplete and unsatisfactory. The now 80 years old quest for a consistent theory of quantum gravity has so far almost entirely focused on mathematical consistency. But as of recently the possibility to look for observational evidence has received an increased amount of attention, as a tool to provide guidance for the construction of of the theory.
Here, I summarize recent developments in the search for
experimental signatures for quantum gravitational effects and how these help to put constraints on the theory-construction. Some of the topics that I will cover are the prospects of finding Planck scale effects in gamma ray bursts, in neutral Kaon oscillations, or with massive quantum oscillators. If time allows, I will also comment on the search for holographic noise and how to find evidence for space-time discreteness.

RADIATION OF AN ACCELERATED CHARGE

Rethinking the dynamics of an accelerated charge from classical concepts. From the idea that radiation
comes from kinetic energy and managing the problem of the auto-energy of a point charge, a system of
non-linear dynamic equations are found and results amenable to experimental verification. In developing, a
relationship between the principle of causality, which affects the direction of time, and the constancy of
mass appears. Another consequence are the fluctuations in the motion of particles, compatible with
Brownian motion and Heisenberg´s indeterminacy principle. The case of gravitational acceleration is also
analyzed, concluding that no electromagnetic radiation is possible and there is no electric field that can
produce a constant acceleration on a point charge. Thus the constant acceleration is an exclusive feature of
gravity.

Quantum signatures of black hole mass superpositions

This document discusses the possibility of a black hole existing in a superposition of different mass states. It proposes a method to model such a scenario by considering a BTZ black hole, which is a solution to Einstein's equations in (2+1) dimensions, in a superposition of two different mass states. The document constructs field correlation functions that include correlations between the different spacetime amplitudes corresponding to the different mass states. It then couples a particle detector to these quantum fields and finds that the detector's excitation probability exhibits resonances at squared rational values of the ratio between the two black hole masses, providing a potential signature of quantum gravitational effects arising from the black hole mass superposition.

Radiation of an Accelerated Charge

1) The document analyzes the classical dynamics of an accelerated electric charge, exploring the idea that electromagnetic radiation comes from the charge's kinetic energy.
2) It derives equations for the motion of an accelerated charge while accounting for the possibility of fluctuations in the charge's mechanical mass due to radiation.
3) Applying Poynting's theorem, it shows that the rate of change of electromagnetic energy within a volume around the charge is equal to the rate of change of the charge's kinetic energy plus the outgoing electromagnetic energy flux due to radiation.

Lambda, the 5th foundational constant considered by EinsteinLaboratoire de recherche sur les sciences de la matière (LARSIM CEA-Saclay)

Lambda, the cosmological constant, is considered the fifth foundational constant in physics along with the speed of light c, Planck's constant h, gravitational constant G, and Boltzmann's constant k. Einstein, de Sitter, Lemaitre, and others originally considered Lambda in their early formulations of cosmology. Lambda represents the energy density of empty space and is related to the curvature of spacetime. Its observed value plays a key role in the current Lambda-CDM model of cosmology, which describes our flat, expanding universe containing dark matter, dark energy, and other components.Gc t lyon-13-12-2016

Universal constants like Planck's constant h, the speed of light c, gravitational constant G, and Boltzmann's constant k can be used to structure theoretical physics. They lead to three main theories: quantum field theory (h and c), general relativity (c and G), and quantum statistics (h and k). While not fully unified, these theories underlie the standard models of particle physics and cosmology. Fundamental metrology provides reliable standards by determining the values of dimensionless constants that depend on h, c, k, and G. Metrology exists at the intersection of fundamental physics described by these theories and emergent physics involving statistical mechanics.Le boson de Higgs, une découverte historique de portée anthropologique

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...

Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

Evidence of Jet Activity from the Secondary Black Hole in the OJ 287 Binary S...

Wereport the study of a huge optical intraday flare on 2021 November 12 at 2 a.m. UT in the blazar OJ287. In the binary black hole model, it is associated with an impact of the secondary black hole on the accretion disk of the primary. Our multifrequency observing campaign was set up to search for such a signature of the impact based on a prediction made 8 yr earlier. The first I-band results of the flare have already been reported by Kishore et al. (2024). Here we combine these data with our monitoring in the R-band. There is a big change in the R–I spectral index by 1.0 ±0.1 between the normal background and the flare, suggesting a new component of radiation. The polarization variation during the rise of the flare suggests the same. The limits on the source size place it most reasonably in the jet of the secondary BH. We then ask why we have not seen this phenomenon before. We show that OJ287 was never before observed with sufficient sensitivity on the night when the flare should have happened according to the binary model. We also study the probability that this flare is just an oversized example of intraday variability using the Krakow data set of intense monitoring between 2015 and 2023. We find that the occurrence of a flare of this size and rapidity is unlikely. In machine-readable Tables 1 and 2, we give the full orbit-linked historical light curve of OJ287 as well as the dense monitoring sample of Krakow.

SDSS1335+0728: The awakening of a ∼ 106M⊙ black hole⋆

Context. The early-type galaxy SDSS J133519.91+072807.4 (hereafter SDSS1335+0728), which had exhibited no prior optical variations during the preceding two decades, began showing significant nuclear variability in the Zwicky Transient Facility (ZTF) alert stream from December 2019 (as ZTF19acnskyy). This variability behaviour, coupled with the host-galaxy properties, suggests that SDSS1335+0728 hosts a ∼ 106M⊙ black hole (BH) that is currently in the process of ‘turning on’. Aims. We present a multi-wavelength photometric analysis and spectroscopic follow-up performed with the aim of better understanding the origin of the nuclear variations detected in SDSS1335+0728. Methods. We used archival photometry (from WISE, 2MASS, SDSS, GALEX, eROSITA) and spectroscopic data (from SDSS and LAMOST) to study the state of SDSS1335+0728 prior to December 2019, and new observations from Swift, SOAR/Goodman, VLT/X-shooter, and Keck/LRIS taken after its turn-on to characterise its current state. We analysed the variability of SDSS1335+0728 in the X-ray/UV/optical/mid-infrared range, modelled its spectral energy distribution prior to and after December 2019, and studied the evolution of its UV/optical spectra. Results. From our multi-wavelength photometric analysis, we find that: (a) since 2021, the UV flux (from Swift/UVOT observations) is four times brighter than the flux reported by GALEX in 2004; (b) since June 2022, the mid-infrared flux has risen more than two times, and the W1−W2 WISE colour has become redder; and (c) since February 2024, the source has begun showing X-ray emission. From our spectroscopic follow-up, we see that (i) the narrow emission line ratios are now consistent with a more energetic ionising continuum; (ii) broad emission lines are not detected; and (iii) the [OIII] line increased its flux ∼ 3.6 years after the first ZTF alert, which implies a relatively compact narrow-line-emitting region. Conclusions. We conclude that the variations observed in SDSS1335+0728 could be either explained by a ∼ 106M⊙ AGN that is just turning on or by an exotic tidal disruption event (TDE). If the former is true, SDSS1335+0728 is one of the strongest cases of an AGNobserved in the process of activating. If the latter were found to be the case, it would correspond to the longest and faintest TDE ever observed (or another class of still unknown nuclear transient). Future observations of SDSS1335+0728 are crucial to further understand its behaviour. Key words. galaxies: active– accretion, accretion discs– galaxies: individual: SDSS J133519.91+072807.4

The cost of acquiring information by natural selection

This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

- 1. Dark matter, Mach’s ether, and the QCD vacuum ArXiv: 1507.00460v2 Gilles Cohen-Tannoudji (LARSIM CEA Saclay) LISHEP 2015 04/07/2015 04/08/2015 DM as QCD vacuum 1
- 2. Outline • Einstein’s address at the Leiden university, may 1920: search for a Mach’s ether for general relativity • LCDM and the dark matter issue • The QCD vacuum in a cosmological context • The hypothesis I submit to debate: Dark energy + Dark matter = Mach’s ether Dark matter = QCD vacuum 04/08/2015 DM as QCD vacuum 2

- 4. 04/08/2015 DM as QCD vacuum 4 Albert Einstein An address delivered in 1920, at the University of Leiden It is true that Mach tried to avoid having to accept as real something which is not observable by endeavoring to substitute in mechanics a mean acceleration with reference to the totality of the masses in the universe in place of an acceleration with reference to absolute space. But inertial resistance opposed to relative acceleration of distant masses presupposes action at a distance; and as the modern physicist does not believe that he may accept this action at a distance, he comes back once more, if he follows Mach, to the ether, which has to serve as medium for the effects of inertia. But this conception of the ether to which we are led by Mach's way of thinking differs essentially from the ether as conceived by Newton, by Fresnel, and by Lorentz. Mach's ether not only conditions the behavior of inert masses, but is also conditioned in its state by them.
- 5. 04/08/2015 DM as QCD vacuum 5 If we consider the gravitational field and the electromagnetic field from the standpoint of the ether hypothesis, we find a remarkable difference between the two. There can be no space nor any part of space without gravitational potentials; for these confer upon space its metrical qualities, without which it cannot be imagined at all. The existence of the gravitational field is inseparably bound up with the existence of space. (…) From the present state of theory it looks as if the electromagnetic field, as opposed to the gravitational field, rests upon an entirely new formal motif, as though nature might just as well have endowed the gravitational ether with fields of quite another type, for example, with fields of a scalar potential, instead of fields of the electromagnetic type.
- 6. 04/08/2015 DM as QCD vacuum 6 Recapitulating, we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether. According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring- rods and clocks), nor therefore any space-time intervals in the physical sense. But this ether may not be thought of as endowed with the quality characteristic of ponderable media, as consisting of parts which may be tracked through time. The idea of motion may not be applied to it.

- 8. Dark matter in astrophysics 04/08/2015 DM as QCD vacuum 8 Rotation curves of stars in galaxies and galaxies in clusters of galaxies Rotation velocities do not decrease with distance at large distance Dark matter invented to address this issue: a medium that exerts a gravitational force that compensate the centrifugal force and prevent the rotating object to escape from the system in which it rotates Centrifugal force Fc=mv2/r , compensated by gravitational force M(r)m/r2 if M(r)=lr i.e. the force exerted by a string with constant (independent of m and of r) string tension Dark matter acts as an ether exerting a gravitational force which derives from a scalar potential
- 9. Dark matter in cosmology: Review of the LCDM standard model (WMAP confirmed by Planck 2015) • Planck 2015 results: The Planck TT, TE, and EE spectra are accurately described with a purely adiabatic spectrum of fluctuations with a spectral tilt ns = 0.968 ± 0.006, consistent with the predictions of single-field inflationary models. Combining Planck data with BAO, we find tight limits on the spatial curvature of the Universe, Wk<0.OO5, again consistent with the inflationary prediction of a spatially-flat Universe. By combining the Planck TT+lowP+lensing data with other astrophysical data, including the JLA supernovae, the equation of state for dark energy is constrained to w = -1.006 ± 0.045 and is therefore compatible with a cosmological constant, as assumed in the base LCDM cosmology. 04/08/2015 DM as QCD vacuum 9

- 16. Consequences of the Heisenberg inequalities • When the number of particles is well determined (for instance in the quantum vacuum where this number is zero) the space-time state of the fields is not determined: they fluctuate • In space-time, the quantum vacuum can be assimilated to a complex medium, seat of non scale invariant quantum fluctuations of the fields • The properties of the quantum vacuum depend on the scale at which it is probed. In cosmology, this scale is provided by the horizon radius which depends on the cosmic time. • If Mach’s ether is to be assimilated to the quantum vacuum, it has to depend on the cosmic time 04/08/2015 DM as QCD vacuum 16
- 17. 04/08/2015 DM as QCD vacuum 17 In the model proposed by Brout, Englert and Gunzig which could be compatible with the primordial inflation phase of LCDM “quantum creation of massy particles can occur in the cosmological context without cost of energy” R. Brout, F. Englert and E. Gunzig, The Creation of the Universe as a Quantum Phenomenon, Annals of Physics 115, 78-106 (1978) (The BEG mechanism ! ) The main point of their argument is that in homogeneous and isotropic cosmologies that obey the cosmological principle, the metric is conformally flat, i.e. such that it is Minkowskian up to a multiplicative factor related to its determinant which can be treated as a scalar field f in Minkowski (flat) space-time. This field gives rise to a negative energy density such that matter carrying positive energy can be created and yet the total energy can be kept fixed and equal to the vacuum energy. This apparent paradox is solved exactly in the same away as in the Brout Englert Higgs mechanism electroweak symmetry breaking, the ghost that appears in the Landau ‘tHooft gauge is canceled by the Nambu Goldstone boson in the unitary gauge. Primordial inflation and the Brout Englert Gunzig mechanism
- 18. 04/08/2015 DM as QCD vacuum 18 The QCD Lagrangian, without quarks or with massless quarks (in the so-called chiral limit), is scale invariant since the coupling constant is dimensionless. But through quantization, this symmetry is broken, one says that it is dynamically broken: this phenomenon is called conformal anomaly. The dynamical breaking of scale invariance is apparent in the fact that “the renormalization has replaced a one-parameter family of unrenormalized theories, characterized by their values of the dimensionless unrenormalized gauge coupling, g0 , by a one-parameter family of renormalized theories, characterized by their value of the dimension-one [renormalization group invariant] scale mass M(g,” (Stephen L. Adler, Einstein gravity as a symmetry breaking effect in quantum field theory Review of Modern Physics, Vol 54, No 3, 729, 1982).This feature is also known as dimensional transmutation This scale mass, independent of the energy at which renormalization is performed, appears as a non-vanishing trace of the renormalized energy-momentum tensor; it is completely physical; it is related to the hadron masses; but, and this is the main point of our proposal, it does have cosmological implications. Since the variation of the action with respect to the metric, is proportional to the energy-momentum tensor, the scale factor of the metric, represented by a scalar field f, is proportional to the trace of the energy-momentum tensor, The QCD vacuum as an ether

- 20. It turns out that DM models involving such BECs have been successfully tried in the literature (Cosmic Structure as the Quantum Interference of a Coherent Dark Wave by Hsi-Yu Schive, Tzihong Chiueh∗ & Tom Broadhurst arXiv:1406.6586). In this reference, the authors show, by means of high precision simulations, that their Axion-like model agrees with the conventional cold dark matter model in the description of large scale structures in the distribution of galaxies and works much better than the conventional one in the description of small scale structure thanks to interferences between the “dark quantum waves” and some waves arising in hydro-dynamical models (Jeans effect). Apart from ultralight bosons like the hypothetical Axion or scalar bosons, relics of the GUT symmetry breaking or of some superstring dynamics, the only bosons susceptible to condense and to lead to observable cosmological effects are the photon and the gluon. In fact weak intermediate and Higgs bosons are unstable and decay into light particles in such a way that they contribute only to the radiation (or relativistic) component in the density budget of present time and are thus negligible. The photon can condense (see the Casimir effect), but again it contributes only to the radiation component and is negligible. There only remains the gluon 04/08/2015 DM as QCD vacuum 20 The only way for such vacuum energy densities to contribute to the dark matter density is to be non relativistic (namely cold), stable, and with only very weak non-gravitational interactions. It seems possible to satisfy all these conditions with Bose Einstein Condensates (BEC): very low temperature at the Hubble horizon, superfluidity, a characteristic of BEC.
