Dark matter is believed to be made up of weakly interacting massive particles and holds galaxies together through gravity, though it does not emit or reflect light. Dark energy is the energy of empty space that is accelerating the expansion of the universe. Understanding dark matter and dark energy could allow for faster-than-light travel and more thorough astronomical research. Only 5% of the universe is visible matter - 25% is dark matter and 70% is dark energy.

Dark matter & dark energy
Dark matter and dark energy make up 95% of the universe. Dark matter is an undetected form of matter that exerts gravitational pull but does not emit or interact with light. Its existence is inferred from its gravitational effects, such as the rotation speeds of galaxies. Dark energy is driving the accelerating expansion of the universe according to Hubble's law, contradicting the expected eventual gravitational collapse. While their effects can be observed, the true nature of dark matter and dark energy remain mysterious, as they have not been directly detected, and may hold potential future applications in spacecraft propulsion if their properties can be better understood.
Dark matter
Dark matter is a hypothetical type of matter that accounts for approximately 85% of the matter in the universe but does not emit, absorb, or interact with electromagnetic radiation. It is believed to play a key role in the formation of galaxies and their structure. While its existence and properties are well-established through its gravitational effects, its exact nature remains unknown. Several experiments are attempting to directly detect dark matter particles through methods like observing signals produced when dark matter particles interact or are destroyed, but so far none have succeeded, and dark matter's composition remains one of the greatest unsolved mysteries in physics.
Dark matter and dark energy
Dark matter makes up 73% of the universe and is composed of unknown particles that do not emit or absorb light but have gravitational effects. Dark energy is 23% and is a repulsive force that is driving the expansion of the universe. Both dark matter and dark energy were hypothesized to explain inconsistencies in cosmological theories and observations of the structure and acceleration of the expanding universe.
Dark Energy And Dark Matter
Observations from the Hubble Space Telescope in 1998 showed that the universe was expanding more slowly in the past than it is today, contrary to expectations. This led scientists to propose either modifications to Einstein's theory of gravity, such as the introduction of dark energy, or the existence of an unknown type of matter, dubbed dark matter, that cannot be detected directly. Dark matter is inferred to make up about 27% of the universe based on its gravitational effects, but its exact nature remains unknown.

Dark matter is invisible matter that makes up 80% of the universe and affects the rotational speeds of galaxies and gravitational lensing. Dark energy is a hypothetical form of energy that covers the universe, increases its expansion rate, and makes up 73% of its energy. While both are unseen and little is known about them, dark matter is matter that affects galaxies whereas dark energy is energy that affects the universe's expansion.

Dark matter is matter that does not emit or absorb light or radiation and can only be detected through its gravitational effects. It makes up 23% of the universe's energy. Its exact particle nature remains unknown. Dark matter was first hypothesized to account for discrepancies between the mass of large astronomical objects determined by their gravitational influence versus the mass calculated from the visible matter they contain. Understanding dark matter is important because it and dark energy make up over 90% of the universe's total energy.
Dark Matter
The document discusses dark matter and provides evidence for its existence from various astronomical observations. It notes that while ordinary matter makes up only about 4% of the universe, dark matter accounts for about 23%. Various properties of dark matter are described, including that it interacts gravitationally but does not emit or absorb light. Possible candidates for dark matter are discussed, including WIMPs (Weakly Interacting Massive Particles), which are favored from both astronomical data and particle physics models. The document outlines how WIMPs could have been thermally produced in the early universe to account for the observed dark matter abundance.
Dark matter and Dark energy
Dark matter makes up about 5 times as much of the matter in the universe as regular matter, though its composition is unknown. It interacts very weakly and was first discovered through its gravitational effects on galaxy rotations. Dark energy makes up about 75% of the universe and is causing its accelerating expansion, though the source is a mystery and quantum effects predict a much larger value. String theory landscape ideas may help explain the observed size of dark energy through vacuum selection in a complicated potential.

Dark matter is estimated to make up 27% of the universe and is defined as matter that does not interact with light but has gravitational effects. While dark matter cannot be seen, evidence for its existence comes from observations of gravitational effects and the cosmic microwave background. Dark matter is thought to be made up of either WIMPs (Weakly Interacting Massive Particles) such as neutrinos or axions, or MACHOs (Massive Compact Halo Objects) which could be black holes, neutron stars, or brown dwarfs.
Dark matter and dark energy (1)
This document discusses gravity and its role in shaping astronomical structures like galaxies and galaxy clusters. It describes how gravity causes stars at the edges of spiral galaxies to rotate at similar speeds to those at the center, and how galaxy clusters contain 10 times more mass than can be accounted for by visible matter alone. The document also mentions how Einstein's theory of general relativity explains the accelerating expansion of the universe driven by dark energy, which exerts a repulsive force that counteracts gravity on large scales.
Insights into Dark Matter
The document discusses evidence for dark matter from astrophysical observations. It is established that dark matter is massive, cold, collisionless, and does not interact electromagnetically. However, its fundamental nature and interactions are unknown. The evidence includes missing mass observations from galaxy rotation curves, cluster dynamics, gravitational lensing as well as cosmological measurements of the cosmic microwave background and matter power spectrum. Future experiments aim to directly detect dark matter particle signatures through anomalies in cosmic ray spectra or indirect signals from early structure formation.
Dark matter
Dark matter is invisible matter that makes up about 21% of the universe. It cannot be seen directly but its existence and properties are known through its gravitational effects on visible matter. There are two main types of dark matter: ordinary matter made up of normal particles and extraordinary dark matter like black holes. Dark matter was first proposed in 1933 by Fritz Zwicky to explain discrepancies in galaxy motions but its exact nature remains mysterious. Current experiments aim to detect dark matter particles but have had conflicting results so far.
BLACK HOLES
1) Black holes were first theorized in 1783 and were described by Einstein's theory of general relativity in 1916. The term "black hole" was coined in 1967.
2) Black holes are regions of space where gravity is so strong that not even light can escape. They form when massive stars collapse at the end of their life cycles.
3) There are three main types of black holes - stellar black holes resulting from collapsed stars, supermassive black holes at the centers of galaxies, and theoretical micro black holes. Black holes cannot be seen directly but their effects on nearby stars and gas provide evidence of their existence.
Black holes powerpoint
This document provides a history and overview of black holes. It discusses that the idea of black holes was first proposed by John Mitchell in the 18th century. Key developments include Einstein's theory of relativity in 1915 and the work of Israel, Carter and Robinson establishing the no-hair theorem in the 1970s. The term "black hole" was first publicly used by John Wheeler and first recorded in an article by Ann Ewing. The document then covers the classification, features and examples of different types of black holes such as their event horizons, singularities, photon spheres, and ergospheres. Black holes can be supermassive, stellar-mass or hypothetical micro black holes. They are also classified based on their properties as

Dark Matter And Energy
The document discusses dark matter and dark energy in the universe. It states that the universe is estimated to consist of 70% dark energy, 25% dark matter, and less than 5% normal matter. Dark energy is blamed for the accelerating expansion of the universe, but its exact nature is unknown. Several hypotheses for dark energy are presented, including that it is a property of space or results from quantum fluctuations. More data is needed to discriminate between theories of dark energy. Dark matter is also not well understood, but is thought to not consist of normal matter like stars, planets, or black holes. Leading candidates for dark matter are axions or WIMPs. Recent telescope observations provide further evidence that dark matter interacts differently than
Dark matter
Dark matter makes up 27% of the universe, is an unidentified type of non-baryonic matter that does not interact with light but has gravitational effects. It cannot be detected with current instruments. Dark energy affects the expansion of the universe and makes up 68% of the universe, but is still a mystery. Early theorists like Fritz Zwicky and Vera Rubin provided evidence for dark matter through its gravitational effects on galaxy clusters and violations of Newton's laws of motion.
Black Holes
This document provides information about black holes, including their structure, theories about their formation and properties, and how they are detected. It discusses that a black hole has a singularity at its center with infinite density, is surrounded by an event horizon beyond which nothing can escape, and may be accompanied by an accretion disk and jets. It also describes Sagittarius A*, the supermassive black hole at the center of the Milky Way, and Cygnus X-1, the first identified black hole.

Black Hole By Pranita & Priyanka
Black holes are objects with such strong gravity that not even light can escape. They form when massive stars collapse at the end of their life cycles. Black holes come in different sizes, from stellar-mass black holes formed by collapsed stars to supermassive black holes millions of times the sun's mass found at the centers of galaxies. Though we cannot see a black hole directly, astronomers can detect them through their effects on nearby objects like gases and stars.
An Introduction about The Black Hole and its types
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars over 8 times the sun's mass die in supernova explosions. Billions of black holes exist between galaxies and millions exist within our own Milky Way galaxy. Black holes can be detected by their gravitational effects on nearby stars and the intense light produced from material falling into supermassive black holes at galaxy cores. Orbiting black holes is possible only at precise speeds - too slow will lead to spiraling in, too fast will escape, and intermediate speeds result in complex rosetta orbits.
Dark Energy
The document discusses dark energy, which accounts for about 70% of the mass of the universe but cannot be directly observed. Measurements of type 1a supernovae found that the expansion of the universe is accelerating, rather than slowing down as expected, suggesting the existence of a mysterious force exerting gravitational repulsion. This dark energy corresponds to Einstein's cosmological constant, which he later disregarded as his "biggest blunder" but may have been correct after all. Current theories hold that dark energy is responsible for the accelerating expansion of the universe.
The black hole theory
This document discusses black holes and their properties. It begins with an introduction to black holes and their structure, including their singularity, event horizon, and accretion disks. It then covers different types of black holes like stellar-mass and supermassive black holes. The document discusses how light behaves near black holes and facts about them. Specific black holes like Sagittarius A* and Cygnus X-1 are mentioned. The formation and growth of black holes over time is summarized. Stephen Hawking's theory about black hole radiation is briefly outlined. The document concludes by discussing how astronomers locate black holes and the ongoing controversy around whether information can escape from black holes.

Dark Matter And Energy Final
Dark matter is believed to make up most of the mass in the universe based on discrepancies found when calculating galaxy masses. In the 1970s, scientists coined the term dark matter to describe this unknown matter. Dark matter could exist as either massive compact objects like black holes or weakly interacting massive particles. Its existence is important because a large amount of matter in the universe cannot be accounted for through other means. In addition, dark matter could influence theories about the universe's creation. Dark energy is a mysterious force that is accelerating the expansion of the universe. It is estimated to make up about 70% of the universe.
The Matter Of Dark Matter
Dark matter is a mysterious form of matter that cannot be seen but accounts for most of the mass in the universe. It was first hypothesized to explain discrepancies between the observed motions of galaxies and clusters and what was predicted based on the amount of visible matter. Dark matter is thought to make up around 23% of the universe, binding galaxies together through gravity. While dark matter cannot be directly observed, its effects on visible matter provide evidence of its existence. Scientists continue searching for dark matter particles and investigating its nature to better understand how it shapes the universe.

It describes how, nearly 14 billion years ago, the universe began as an infinitely small, dense, and hot ball that rapidly expanded and cooled over time, giving rise to space, matter, and energy. It also explains how cosmic inflation theory proposes that the early universe expanded exponentially faster than the speed of light for a fraction of a second, growing trillions of times larger and helping to explain the large-scale structure of the present-day universe.

Our universe is a vast and complex entity, and while our knowledge of it has advanced significantly, scientists are still working to unveil many mysteries. One such incredible secret of "Dark Matter Stars" has been revealed by the James Web Telescope (JWT).
The James Web Telescope has observed such an object in the universe that has never been witnessed before. This object is a dark star. Dark stars are entirely different from normal stars. Normal stars get energy from fusion reactions to illuminate whereas dark stars are made of dark matter. By analyzing this star, we can understand many things in the universe that we never know before.
The universe is divided into three parts i.e. visible matter (atoms), dark matter, and dark energy. Visible matter is only 4.6% of the universe, and dark matter is 24% while dark energy is composed of 71.4% of the universe. All the visible things like humans, mountains, the sun, the moon, etc. make up the visible universe that is made from visible matter. We don't know much about the dark matter that makes up 24% of the universe. We only know that it is made up of dark matter but how? We know very little about it. The third part is the dark energy that expands our universe gradually.

Black Holes
Black holes are formed when massive stars over 10 times the size of the sun explode in supernovae, leaving behind an extremely dense collapsed object with strong gravity. Scientists find black holes by measuring light like x-rays and radio waves emitted by matter around them, and by observing stars orbiting black holes and using gravity and motion to prove their existence.
Black Holes Final Draft
Black holes are formed when massive stars over 10 times the size of the sun explode at the end of their life in supernovae. This leaves behind an extremely dense object with strong gravity that collapses in on itself to zero volume. Scientists can find black holes by measuring light like x-rays and radio waves from matter around it, and by tracking the orbit and speed of stars near the black hole to determine its gravitational pull.
Astronomers have found dark matter in a variety of environments- Name.docx
Astronomers have found “dark matter” in a variety of environments. Name the places where dark matter has been found, and briefly describe how the discovery was made in each case. The question is: In what way is this similar to the construction of Hubble’s law?
Solution
The matter that we cannot observe directly \"dark matter,\". Many evidence are found shows that super massive black hole (dark matter) is located at the galactic centre.
The large fraction of invisible matter is present in the universe because gravity produced by all luminous body is very less compared to amount of gravity required for the stars to orbit around galaxies and the galaxies to their galactic centre.
According to Hubble\'s law all objects appear to be farther away from us.This is possible if the expansion of the universe is accelerating , not decelerating. In order for the universe to accelerate, there must be some force pushing all of the galaxies away from each other, and this force must be strong enough to counteract the deceleration by gravity. Today, we do not know the ectula caue of this. his new mysterious force provided by darks matter, dark energy .

Dark Matter And Dark Energy
- 1. Dark Matter And Dark Energy by Leah V.
- 2. Dark Matter What is it? Dark matter is believed to be made up of WIMPs (weakly interacting massive particles) or axions but it is not yet confirmed. Galaxies and clusters of galaxies are gravitationally held together by this dark matter. It doesn’t reflect light or give off electromagnetic radiation.
- 3. Dark Energy “ Empty space” isn’t empty but can possess its own energy called dark energy. Dark energy forces space to expand and is making it expand at a quicker rate as time goes on. By harnessing dark energy, scientists could learn how to travel faster than the speed of light.
- 4. How will Dark Matter and Dark Energy effect what we know about astronomy? This will impact what we know about astronomy because, it could allow us to conduct much more thorough research on other planets, stars, galaxies, ect. by being able to travel to them
