Dark matter are invisible objects that react with matter by gravitational force. Scientists believe that the dark matter is made up of exotic particles like WIMPs(Weakly Interacting Massive Particles).In physical cosmology, dark energy is an exotic form of energy that permeates all of space and tends to increase the rate of expansion of the universe.Dark energy is the most popular way to explain recent observations that the universe appears to be expanding at an accelerating rate. In the standard model of cosmology, dark energy currently accounts for 73% of the total mass-energy of the universe.

The module provides teachers with tools to show how dark matter was discovered, to explain why it remains a mystery, and to share the passion of scientists who are trying to discover what its made of. • www.perimeterinstitute.ca --- In astronomy and cosmology, dark matter is a form of matter that is undetectable by its emitted electromagnetic radiation, but whose presence can be inferred from gravitational effects on visible matter and background radiation. According to present observations of structures larger than galaxies, as well as Big Bang cosmology, dark matter accounts for the vast majority of the mass in the observable universe. Dark matter was postulated by Fritz Zwicky in 1934, to account for evidence of "missing mass" in the <b>...</b>

Watch this and other space videos at SpaceRip.com Scientists have further narrowed the search for a hypothetical particle that could be dark matter, the mysterious stuff that makes up 80 percent of all the mass in the universe. This video from NASA Astrophysics presents the new results, compiled from two years' worth of data from NASA's Fermi Gamma-ray Space Telescope. Gamma rays are very energetic light, and the telescope looks for faint gamma-ray signals that are generated by a variety of sources, such as gas and dust spiraling into supermassive black holes or exploding stars. But another potential source of gamma rays is dark matter. Although no one is sure what dark matter is, one of the leading candidates is a yet-to-be-discovered particle called a weakly interacting massive particle (WIMP). When two of these WIMPs meet, the theory goes, they can annihilate one another and generate gamma rays. There are many possible versions of WIMPs, and they're expected to span a wide range of masses, producing a range of gamma rays with different energies. Using Fermi, the scientists focused on 10 small galaxies that orbit the Milky Way, searching for gamma-ray signals within a specific range of energies. They found no signs of annihilating WIMPs, which rules out certain kinds of WIMPs as dark-matter candidates.

There's more to the cosmos than meets the eye. About 80 percent of the matter in the universe is invisible to telescopes, yet its gravitational influence is manifest in the orbital speeds of stars around galaxies and in the motions of clusters of galaxies. Yet, despite decades of effort, no one knows what this "dark matter" really is. Many scientists think it's likely that the mystery will be solved with the discovery of new kinds of subatomic particles, types necessarily different from those composing atoms of the ordinary matter all around us. The search to detect and identify these particles is underway in experiments both around the globe and above it. Scientists working with data from NASA's Fermi Gamma-ray Space Telescope have looked for signals from some of these hypothetical particles by zeroing in on 10 small, faint galaxies that orbit our own. Although no signals have been detected, a novel analysis technique applied to two years of data from the observatory's Large Area Telescope (LAT) has essentially eliminated these particle candidates for the first time. WIMPs, or Weakly Interacting Massive Particles, represent a favored class of dark matter candidates. Some WIMPs may mutually annihilate when pairs of them interact, a process expected to produce gamma rays -- the most energetic form of light -- that the LAT is designed to detect. The team examined two years of LAT-detected gamma rays with energies in the range from 200 million to 100 billion electron volts <b>...</b>

Dark matter has always had mysterious properties, but now it appears to be even more enigmatic than scientists predicted. Researchers are re-evaluating their assumptions about dark matter in light of a cosmic pile-up 2.4 billion light years away. Galaxies and dark matter were previously believed to stay together even during a collision of galaxies. But a new report from Hubble observations of a merging galaxy cluster known as Abell 520 suggests high-speed galaxy cluster collisions can leave a pile of dark matter rubble at the scene of the accident. Dark matter, detected only by its gravitational effect, is believed to provide the invisible "scaffolding" for the universe's structure, binding galaxy clusters through gravitational force into a giant cosmic web. But since we can only see about 15 percent of the universe's matter anyway, we're probably in store for many more confounding revelations. It's a good thing that, like galaxies and dark matter, scientists and their theories don't get too attached.

Particle Physics Foundations of Dark Matter, Dark Energy, and Inflation (1/3) © CERN Kolb, Edward (Rocky) (speaker) (University of Chicago) CERN. Geneva Academic Training Lecture Regular Programme Ninety-five percent of the present mass-energy density of the Universe is dark. Twenty-five percent is in the form of dark matter holding together galaxies and other large scale structures, and 70% is in the form of dark energy driving an accelerated expansion of the universe. Dark matter and dark energy cannot be explained within the standard model of particle physics. In the first lecture I will review the evidence for dark matter and the observations that point to an explanation in the form of cold dark matter. I will then describe the expected properties of a hypothetical Weakly-Interacting Massive Particle, or WIMP, and review experimental and observational approaches to test the hypothesis. Finally, I will discuss how the LHC might shed light on the problem. In the second lecture I will review the theoretical foundations and observational evidence that the dominant component of the present mass density of the Universe has a negative pressure, which leads to an accelerated expansion of the Universe. I will then describe various approaches to understand the phenomenon. Finally, I will describe an observational program to understand the nature of dark energy.

Please visit and join to learn more. www.astronomy.com In this series I give you an overview of important ideas in the area of cosmology. This video is the second in the series, and focuses on dark matter. Using various detectors and research methods, astronomers have determined that the stuff we see in space — stars, gas, and dust — amounts to less than 5 percent of the universe. This stuff is ordinary matter, and it's made up of protons, neutrons, and electrons. Scientists call ordinary matter "baryonic matter" because protons and neutrons are subatomic particles called baryons. So if ordinary matter is only about 5 percent of the universe, what's the other 95 percent? Well, about 23 percent is something called dark matter. The remaining 72 percent is a mysterious pervasive force called dark energy. I'll explain more about dark energy in my next video. Alright, back to dark matter. This mysterious mass is a type of matter that doesn't emit, absorb, or reflect any type of light (so, for example, it doesn't emit X rays or absorb infrared radiation). Dark matter is therefore invisible. If it's invisible, how do astronomers have any idea it's there? Dark matter interacts with ordinary matter through gravity. Its gravitational interaction is how astronomers first found out dark matter exists. In 1933, a Swiss astrophysicist by the name of Fritz Zwicky first proposed dark matter's existence. While studying the Coma galaxy cluster, he found that the galaxies' gravity alone was <b>...</b>

This is an idea, a theory about what Dark Matter and Dark Energy could be. The fabric of space is the surface of the multidimensional ocean, with matter "floating" on it. Like ice floating on water, Dark Matter is the unseen portion of regular matter below our fabric of space, that never the less, has a gravitational effect, curving its surface. At the macro scale of galaxies, these effects become apparent and are amplified by the singularities found at the center and throughout the galaxy. The Multi-dimensional universe exerts pressure on the fabric of space, like the inner pressure of a balloon expanding its surface. The fabric of space acts like the surface of an ocean who's depth is the rest of reality. There is a search for Dark Matter, but what if what is found doesn't come close to the amount that appears to be there.. What if we simply misunderstand the structure of matter and the way our multi-dimensional universe is layered.. Ideas must be shared, I just want to give my contribution to the debate.

What if you could fly through the universe and see dark matter? While the technology for taking such a flight remains under development, the technology for visualizing such a flight has taken a grand leap forward with the completion of the Bolshoi Cosmological Simulation. After 6 million CPU hours, the world's seventh fastest supercomputer output many scientific novelties including the above flight simulation. Starting from the relatively smooth dark matter distribution of the early universe discerned from the microwave background and other large sky data sets, the Bolshoi tracked the universe's evolution to the present epoch shown above, given the standard concordance cosmology. The bright spots in the above video are all knots of normally invisible dark matter, many of which contain normal galaxies. Long filaments and clusters of galaxies, all gravitationally dominated by dark matter, become evident. Statistical comparison between the Bolshoi and current real sky maps of actual galaxies show good agreement. Although the Bolshoi simulation bolsters the existence of dark matter, many questions about our universe remain, including the composition of dark matter, the nature of dark energy, and how the first generation of stars and galaxies formed.

Structurally, DMT is analogous to the neurotransmitter serotonin (5-HT), the hormone melatonin, and other psychedelic tryptamines, such as 5-MeO-DMT, bufotenin, and psilocin and is our connection to the other 99% of reality that we cannot see.. Dmt is naturally made in the human body and the highest amounts are in the pineal gland.. The pineal gland is responsible for the production of melatonin, a hormone that is secreted in response to darkness, and is also the site in the brain where the highest levels of Serotonin can be found (Sun et al, 2001). In the pineal, 5-HT (Serotonin) concentration displays a remarkable diurnal pattern, with day levels much higher than night levels. Serotonin plays an important role in sleep, perception, memory, cardiovascular activity, respiratory activity, motor output, sensory and neuroendocrine function.

Standard cosmology involves detailed models, whose predictions agree with, and explain, much of what astronomers see. However, there are a growing number of observations that are deeply puzzling. For example, a number of independent astronomical observations have provided strong evidence for the existence of vast quantities of matter that do not emit or reflect electromagnetic radiation of any type (visible light, microwaves, gamma rays, etc), and thus cannot be seen. It is called dark matter. How do we know it's there? Even though we cannot see it, it exerts very clear gravitational influences on the matter and radiation we can see.
