Quantum entanglement is a phenomenon where the quantum properties of two or more particles become linked in such a way that measuring one particle instantly affects the other, even if they are separated by a large distance. Einstein referred to this as "spooky action at a distance" as it appears to contradict relativity. When the spin of one entangled particle is measured, the other particle will automatically resolve to the opposite spin instantaneously. This effect seems to allow faster-than-light communication, though the exact mechanism remains unclear. Potential applications include quantum computing and teleportation.

In 1994, Miguel Alcubierre proposed a method for changing the geometry of space by creating a wave that would cause the fabric of space ahead of a spacecraft to contract and the space behind it to expand. The ship would then ride this wave inside a region of flat space, known as a warp bubble, and would not move within this bubble but instead be carried along as the region itself moves due to the actions of the drive.
In a recent study, physicist Dr Erik Lentz outlined a way that a rocket could theoretically travel faster than light – or over 186,000 miles per second. At that speed, astronauts could reach other star systems in just a few years, allowing humanity to colonise faraway planets. Current rocket technology would take roughly 6,300 years to reach Proxima Centauri, the closest star to our Sun. So-called “warp drives” have been proposed before, but often rely on theoretical systems that break the laws of physics. That’s because according to Einstein’s general theory of relativity, it’s physically impossible for anything to travel faster than the speed of light.
Dr Lentz, a scientist at Göttingen University in Germany, says his imaginary warp drive would operate within the boundaries of physics. While other theories rely on “exotic” concepts, such as negative energy, his gets around this problem using a new theoretical particle. These hyper-fast “solitons” can travel at any speed while obeying the laws of physics, according to a Göttingen University press release. A soliton – also referred to as a “warp bubble” – is a compact wave that acts like a particle while maintaining its shape and moving at constant velocity.
Dr Lentz said he cooked up his theory after analysing existing research and discovered gaps in previous warp drive studies. He believes that solitons could travel faster than light and “create a conducting plasma and classical electromagnetic fields”. Both of these concepts are understood under conventional physics and obey Einstein’s theory of relativity. While his warp drive provides the tantalising possibility of faster-than-light travel, it’s still very much in the idea phase for now.
The contraption would require an enormous amount of energy that isn’t possible using modern technology. “The energy savings would need to be drastic, of approximately 30 orders of magnitude to be in range of modern nuclear fission reactors,” Dr Lentz said. The research was published in the journal Classical and Quantum Gravity.
This article delves into the realms of quantum physics and quantum computing, designed with beginners in mind. If you're entirely new to the world of quantum physics and quantum computing, this resource offers an ideal opportunity to grasp the inner workings of these subjects.
While my intention was to provide comprehensive coverage of a wide range of topics, I found it challenging to delve deeply into each one. As a result, I've only touched upon a few key subjects in this article. This marks my inaugural attempt at writing an article, so I acknowledge the possibility of errors. Nonetheless, the experience of embarking on this writing journey has been quite rewarding.
Sometimes, if you want to understand how nature truly works, you need to break things down to the simplest levels imaginable. The macroscopic world is composed of particles that are-if you divide them until they can be divided no more-fundamental. They experience forces that are determined by the exchange of additional particles (or the curvature of spacetime, for gravity), and react to the presence of objects around them. At least, that’s how it seems. The closer two objects are, the greater the forces they exert on one another. If they’re too far away, the forces drop off to zero, just like your intuition tells you they should. This is called the principle of locality, and it holds true in almost every instance. But in quantum mechanics, it’s violated all the time. Locality may be nothing but a persistent illusion, and seeing through that facade may be just what physics needs.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.

called it "spooky action at

to contradict the special
theory of relativity .
Later Schrodinger defined
the idea as
'entanglement'.

WHAT IS QUANTUM
ENTANGLEMENT?
Quantum entanglement is a phenomenon wherein the quantum
properties of two (or more) particles become codependent,
with the properties of one being instantaneously affected by
measurements conducted on the other.
4. z
Example
A pair of electrons having opposite spins, with the
actual spin of each particle remaining in a state of
quantum uncertainty .On the separation of the
pair of particles, even by a huge distance, and on
measuring one particle’s spin the other particle’s
spin will automatically resolve itself in the other
direction. On the separation of the pair of
particles, even by a huge distance, and on
measuring one particle’s spin the other particle’s
spin will automatically resolve itself in the other
direction. This effect occurs instantaneously,
apparently breaching the velocity of light and the
rules of relativity, a phenomenon that Einstein
referred to as spooky action at a distance.
7. z
SECOND INTERPRETATION
The two entangled particles may theoretically be simultaneously
controlled by a “brain” or “controller”. This “brain/controller” may
theoretically issue a signal to both particles at the same instant
causing them to act as they do at the same instant.
8. z
THIRD INTERPRETATION
Information from one of the two entangled particles may
theoretically be carried to the other particle by an extremely fast
carrier wave that travels faster than the velocity of light causing
the other particle to act with an opposite spin at practically the
same instant .These particles are known as Tachyons.
9. z
Quantum entanglement does in fact happen and entangled
particles do appear to “communicate” with each other across
space faster than the velocity of light. Experiments with more
than two entangled particles switching states together across
many tens of kilometers have already been conducted.
