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 is an invisible phenomenon that acts on visible matter through gravity. It accounts for 6 times more mass in the universe than normal matter. Fritz Zwicky discovered evidence of "invisible matter" in galaxies in 1933 while Vera Rubin provided further evidence in the 1970s, though they were initially disregarded. String theory may help explain dark matter through postulated supersymmetric particles. Dark energy is a hypothetical form that permeates space, causing accelerated expansion of the universe, and may account for most of its mass. It produces an opposite effect to gravity. String theory also provides several potential explanations for dark matter through concepts like supersymmetric particles, branes, and extra dimensions.
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.

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.
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 & 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 and dark energy
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 and Dark Energy
This document discusses the history of discoveries related to dark matter and dark energy. It describes how observations over the past 100 years have shown that normal matter only accounts for about 4% of the matter in the universe. The other 96% is believed to be dark matter and dark energy. Evidence from galaxy rotations, gravitational lensing, and galaxy cluster dynamics provides strong evidence for the existence of dark matter, which is believed to be some non-baryonic, non-luminous particle that interacts only through gravity and the weak force.

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.

Dark matter is invisible matter that accounts for approximately 27% of the mass-energy in the universe. Although it cannot be directly observed, astronomers deduce its existence through its gravitational effects, such as the anomalous rotation curves of galaxies. Dark matter is classified as cold, warm, or hot depending on the size of protogalaxies, and may consist of either baryonic matter like protons and neutrons or nonbaryonic particles like axions. It plays a prominent role in science fiction works but descriptions are often inconsistent with scientific understanding.
Dark Matter Group AC 8
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.
Black holes presentation
Black holes are objects with extremely strong gravitational fields that do not allow anything, including light, to escape once it passes the event horizon. They are formed when very massive stars collapse at the end of their life cycles. Black holes are small but incredibly dense, with all their mass concentrated at a central singularity. If material such as gas from a nearby star falls into a black hole, it becomes heated and glows, making the black hole visible with telescopes.
Black holes
1) Black holes are formed when massive stars over 10 times the mass of the Sun collapse in on themselves due to nuclear fusion and strong gravitational forces.
2) We can detect the presence of black holes through the X-rays emitted when matter around the black hole is heated and through gravitational lensing effects on light passing by.
3) If you fell into a black hole, the extreme tidal forces would spaghettify and kill you before you reached the central singularity, and from your perspective you would see the universe compressed into a brief flash of light before destruction.
Black hole
A black hole is a place in space where gravity pulls so much that even light can not get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently than other stars.

This document discusses dark matter and dark energy. Dark matter is a hypothetical form of matter that does not emit or absorb light but has gravitational effects. Its existence can be inferred through gravitational lensing and the rotation curves of galaxies. Dark energy is theorized to be causing the accelerating expansion of the universe. Current research includes experiments trying to directly detect dark matter particles and gravitational wave observatories seeking to better understand dark energy. Future experiments such as LSST and Euclid aim to provide more data to study these mysterious components of the universe.
Black holes
This document discusses black holes. It begins with a brief history of ideas about black holes from the 18th century to modern times. It then describes how black holes form from massive stars undergoing gravitational collapse at the end of their life cycles. It outlines the key characteristics of black holes, including their structures consisting of singularities surrounded by event horizons. The document also notes that black holes can continue growing by absorbing matter and merging with other objects. In conclusion, it states that while there is no limit to the size of black holes, the largest are likely in the centers of galaxies and contain billions of solar masses.
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.
Neutron stars and white dwarfs
Neutron stars are extremely dense collapsed stars sometimes left behind after a supernova explosion. They are created when giant stars die in supernovas and their cores collapse, compressing the protons and electrons into neutrons. Neutron stars have a diameter of only 20 kilometers but contain 1.5 times the mass of the Sun concentrated into that small, dense space. White dwarfs are stellar remnants composed mainly of electron-degenerate matter. They have a mass comparable to the Sun's but contained within a volume comparable to Earth's. In the future, as the Sun dies it will expand into a red giant, engulfing the inner planets, before collapsing into a hot, dense white dwarf.

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.

El documento habla sobre la teoría del hiperespacio y la teoría del todo. Explica cómo la teoría de cuerdas en 10 dimensiones podría unificar las cuatro fuerzas fundamentales y ser la clave para una teoría del todo. También describe cómo Edward Witten ha sido fundamental en el desarrollo de la teoría de cuerdas y es considerado el sucesor intelectual de Einstein en física teórica.
Blackholes
The document summarizes what is known about black holes, including:
- Einstein's theory of general relativity predicted black holes could exist, though they were not believed to be real until convincing evidence in the 1970s.
- Black holes are extremely dense regions with gravity so strong that not even light can escape, where the escape velocity exceeds the speed of light.
- Observational evidence like hot material falling into black holes and jets of glowing gas have shown that while invisible, black holes' effects can be observed and they are widespread throughout the universe.
Dark energy & dark matter
El documento propone una hipótesis sobre el origen de la materia y energía oscura. Sugiera que antes del Big Bang, se estaba creando antimateria en la "brana" que luego sería nuestro universo, debido a las predicciones de la teoría cuántica en el vacío. Luego, durante el Big Bang se creó más materia y antimateria, y la gran cantidad de antimateria existente colisionó y se unió debido a las altas temperaturas, liberando grandes cantidades de energía oscura y una pequeña cantidad de materia oscura.
Black Holes and its Effects
1. Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse at the end of their life cycles.
2. There are two main types of black holes - static and rotating. The rotating type, known as Kerr black holes, form when collapsed stars have angular momentum.
3. As a star collapses, it passes through stages as a red giant, white dwarf, and neutron star until its mass exceeds around 3 solar masses, causing it to collapse entirely into a black hole with a singularity at its center.
THE UNIVERSE
The document provides an overview of the size and contents of the universe. It begins by explaining that the universe includes all physical matter and energy, from atoms to galaxies. It then notes that the tour will focus on the part of the universe outside Earth. The document goes on to summarize how human understanding of the universe's size has expanded over time, from only a few thousand light years across to immensely larger. It lists some of the key components that make up the universe, such as matter, energy, planets, stars, and more.
Our universe
The document discusses key facts about our planet Earth. It begins by providing context about our solar system and universe. It then explains that Earth is the third planet from the sun and the only planet that supports life. The document goes on to describe how Earth formed from a hot cloud of gases and cooled over millions of years, developing a crust, mantle and core similar to an egg. Volcanoes are mentioned as openings where molten material from the core is forced out of the crust.
Theories Of The Universe
The document discusses several theories of the origin and evolution of the universe:
1) The Big Bang theory proposes that the universe began as a tiny, dense ball that exploded approximately 13.7 billion years ago, resulting in the formation of stars, planets, and all existing matter.
2) The creationist theory states that God created the universe in seven days, as described in the Bible. Some believe the universe is only around 6,000 years old based on this theory.
3) The holographic theory suggests that the entire universe is actually a hologram and everything within it, including living things, would also be holograms. This theory differs significantly from all others.
The origin of the universe
The document summarizes theories about the origin and evolution of the universe. It describes the widely accepted Big Bang theory, which proposes that the universe began in a hot, dense state and has been expanding ever since. It also briefly outlines alternative theories such as inflationary universe, stationary universe, and oscillating universe. Finally, it provides an overview of the major events and epochs in the development of the universe according to the Big Bang theory, from the initial singularity to the formation of stars and galaxies.

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.

Period 7 - Gah Tang - The Invisible Dilemma
Dark matter is invisible matter that can only be detected through its gravitational effects. It makes up about 27% of the universe and helps hold galaxies together. Studying dark matter could bolster theories of gravity, revolutionize the Big Bang theory, and lead to new discoveries like dark energy. The presentation argues that pursuing dark matter research can advance human knowledge and progress society.
Kool Aid
Scientists believe the universe is comprised of over 95% dark matter and dark energy. Dark matter, which accounts for about 25% of the universe, is matter that cannot be seen as it does not reflect light. Little is known about dark matter. Dark energy, which accounts for over 70% of the universe, is a type of energy that affects the expansion of the universe opposite to matter and energy. Theories for both dark matter and dark energy have been proposed but more research is still needed to fully understand these phenomena.
Dark Eneary and Dark Mass
This document provides an overview of dark matter and dark energy from both observational evidence in the universe and theoretical work done at particle accelerators in laboratories. It summarizes that observational evidence shows the universe is made up of 70% dark energy, 25% dark matter, and only 5% ordinary matter. While much is known about the basic features and inventory of the universe, deep puzzles remain about reconciling gravity and quantum mechanics, the nature of dark matter and dark energy, and resolving why observations of dark energy are so much smaller than theoretical predictions. The document discusses how ideas like extra dimensions, supersymmetry, and multiple compactifications in string theory attempt to address these puzzles, but that challenges remain in fully explaining dark energy and connecting theory to

- 99% of the universe is believed to be dark matter. Scientists are convinced that only 1% of the 5% of baryonic matter present in the universe can be seen.
- Evidence has accumulated that there is more matter in galaxies than what meets the eye through telescopes. As much as 90% of the matter in the universe must be in some "dark" form.
- Observations of galaxy rotation curves showed that stars at the outer edges of galaxies move at the same speed as inner stars, even though there isn't enough visible matter to account for the gravitational force needed to keep them in orbit, suggesting additional unseen "dark matter" is present.

Dark matter and dark energy make up 95% of the universe, with dark matter comprising 25% and dark energy 70%. Dark matter cannot be seen directly and can only be detected through its gravitational effects.

A black hole is a region of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse at the end of their life cycles. There are several types of black holes including stellar black holes formed by collapsed stars and supermassive black holes millions to billions times the mass of our sun. As objects fall into a black hole's event horizon, they become "spaghettified" as the black hole's immense gravity stretches and pulls them apart.

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.

What is a black hole
Black holes are regions of space where gravity is so strong that not even light can escape. They form when very massive stars collapse at the end of their life cycles. While black holes cannot be seen directly, astronomers can detect them by observing their effects on nearby objects like stars and gas, and through detection of x-rays emitted during accretion. Black holes come in different sizes, from stellar-mass black holes up to supermassive black holes that may exist at the centers of galaxies.

Universe.ppt
The document discusses evidence that supports the Big Bang theory of the origin and expansion of the universe. It describes two key pieces of evidence: 1) the cosmic microwave background radiation, which is radiation that comes from all directions in space and is thought to be remnants of the early universe, and 2) red shift observations showing that distant galaxies are moving away, which is evidence the universe is expanding. It also explains that an open or closed universe is possible depending on whether the mass of the universe is enough to overcome the expansion driven by dark energy.
DARK MATTER

String theory of particle physics
String theory proposes that fundamental particles are not point-like but are tiny vibrating strings. It aims to unify quantum mechanics and general relativity by incorporating gravity into a theory of everything at very small scales. String theory predicts that spacetime has 10 dimensions rather than the observed 4 dimensions, with the extra 6 dimensions being curled up too small to detect directly. While strings have never been observed, string theory remains a promising area of research as the only known way to reconcile quantum mechanics and general relativity.
Black holes
Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when large stars collapse at the end of their life cycles, compressing their mass into a tiny space. There are several types of black holes including stellar black holes formed by collapsed stars and supermassive black holes found at the center of galaxies containing billions of solar masses. If matter enters a black hole's event horizon, it becomes "spaghettified" as tidal forces stretch and compress it due to the extreme warping of spacetime.
Black hole
Hey I'm DIVYA SHREE NANDINI. I'm here with my new presentation on Black Hole. I'm sure you'll find it interesting. well first thing what is black hole- "Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. A black hole can be formed by the death of a massive star. When such a star has exhausted the internal thermonuclear fuels in its core at the end of its life, the core becomes unstable and gravitationally collapses inward upon itself, and the star’s outer layers are blown away. The crushing weight of constituent matter falling in from all sides compresses the dying star to a point of zero volume and infinite density called the singularity." wanna know more about it then come with me. :)
Black holes definitivo
Black holes form from dying massive stars and are regions of space where gravity is so strong that nothing, not even light, can escape. They have an event horizon boundary and extreme density at the singularity at the center. Small stellar black holes form from supernovae, while supermassive black holes with masses of billions of suns are found at the centers of galaxies. Matter falling into a black hole's intense gravity is stretched or "spaghettified" as it crosses the event horizon.

Beyond the Advance Presentation for By the Book 9
In June 2020, L.L. McKinney, a Black author of young adult novels, began the #publishingpaidme hashtag to create a discussion on how the publishing industry treats Black authors: “what they’re paid. What the marketing is. How the books are treated. How one Black book not reaching its parameters casts a shadow on all Black books and all Black authors, and that’s not the same for our white counterparts.” (Grady 2020) McKinney’s call resulted in an online discussion across 65,000 tweets between authors of all races and the creation of a Google spreadsheet that collected information on over 2,000 titles.
While the conversation was originally meant to discuss the ethical value of book publishing, it became an economic assessment by authors of how publishers treated authors of color and women authors without a full analysis of the data collected. This paper would present the data collected from relevant tweets and the Google database to show not only the range of advances among participating authors split out by their race, gender, sexual orientation and the genre of their work, but also the publishers’ treatment of their titles in terms of deal announcements and pre-pub attention in industry publications. The paper is based on a multi-year project of cleaning and evaluating the collected data to assess what it reveals about the habits and strategies of American publishers in acquiring and promoting titles from a diverse group of authors across the literary, non-fiction, children’s, mystery, romance, and SFF genres.

Dark Matter And Energy
- 1. Dark Matter and Energy By Ben T.
- 2. Dark Energy More is known about it than what is actually known. The universe is decided to be 70% dark energy, 25% dark matter, less than 5% normal matter. Scientist are blaming dark energy for the expansion of the universe.
- 3. Explanations for Dark Energy It’s a property of space. Empty space can posses it’s own energy. Quantum theory of matter- "empty space" is actually full of temporary ("virtual") particles that continually form and then disappear. It’s a new type of dynamical energy, possibly a fluid or field that has the opposite effect on universe expansion than normal matter and energy. Einstein’s theory of gravity is not correct.
- 4. What Needs to be Done In order to make a decision between all of the different possibilities is simply more data and better data. There is a mission in the planning stages that will provide Universe observations for theorists to discriminate between the theories with. Until then the mystery remains.
- 5. Visual The image above shows how the universe has expanded over time. Scientists have theorized that the accelerated expansion is due to a mysterious dark energy
- 6. Dark Matter We are more sure what it’s not that what it is. Its not, In the forms of stars and planets that we see. Dark clouds of normal matter. Antimatter because antimatter gives up gamma rays and we don’t see that with the dark matter. Incredibly large black holes.
- 7. It might be… There are a few possibilities left . It could still be baryonic matter if it were to be tied up in brown dwarfs or in small highly dense bits of heavy elements. The most plausible possibility however is that it is not baryonic but rather made up of more exotic particles such as axions or WIMPS. (Weakly Interacting Massive Particles)
- 8. New Breakthrough The Hubble Space Telescope and Chandra X-ray observatory have captured observations of powerful collisions of galaxy clusters. The observations seem to indicate that a titanic collision has separated dark from ordinary matter. This seems to be similar to the Bullet Cluster showing that the Bullet Cluster is not a unique case.
- 10. Bibliography above, scientists have come up with the composition that we described, ~70% dark energy, ~25% dark matter, and ~5% normal matter. What is dark matter?.
