What is Dark Matter? Dark matter versus dark energy. Although dark matter makes up most of the matter of the universe, it only makes up about a quarter of the composition. The universe is dominated by dark energy. After the Big Bang, the universe began expanding outward.

Outer space Data indicates that the majority of the mass-energy in the observable universe is a poorly understood vacuum energy of space which astronomers label dark energy. Intergalactic space takes up most of the volume of the Universe, but even galaxies and star systems consist almost entirely of empty space.

Matter For other uses, see Matter (disambiguation). In the classical physics observed in everyday life, matter is any substance that has mass and takes up space; this includes atoms and anything made up of these, but not other energy phenomena or waves such as light or sound.

Matter: Definition & the Five States of Matter Matter is the “stuff” of the universe — the atoms, molecules and ions that make up all physical substances. Matter is anything that has mass and takes up space. Energy is the capacity to cause change. Energy cannot be created or destroyed; it can only be conserved and converted from one form to another. Potential energy is the energy stored in an object due to its position — for example, a bucket of water balanced over a doorway has the potential to fall.

What is a Plasma? Plasmas are the most common form of matter, comprising more than 99% of the visible universe. Plasma is by far the most common form of matter known. Plasma in the stars and in the tenuous space between them make up over 99% of the visible universe and perhaps most of that which is not visible. On earth we live upon an island of ordinary matter.

astronomy The intensity of cosmic microwave The average density of matter within it. Measurement of the sizes of hot spots in the temperature distribution of the cosmic microwave background suggests that the universe is flat. Yet, the combined density of all the matter and energy we see, plus the dark matter we infer, is only about a quarter of the critical density.

Introduction The term matter refers to anything that occupies space and has mass—in other words, the “stuff” that the universe is made of. All matter is made up of substances called elements, which have specific chemical and physical properties and cannot be broken down into other substances through ordinary chemical reactions.

Observable universe For other uses, see Universe (disambiguation). The Universe is all of time and space and its contents. It includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space, and all matter and energy. The observable universe is about 28 billion parsecs (91 billion light-years) in diameter. The size of the entire Universe is unknown, but there are many hypotheses about the composition and evolution of the Universe.

Mass, Size, and Density of the Universe The mass density of visible matter (i.e., galaxies) in the Universe is estimated at 3e-28 kg/m^3 (3e-31 times the mass density of water). The radius of the visible Universe is estimated at 1.7e26 m (18 thousand million lightyears) plus or minus 20 percent or so.

- This Hubble Space Telescope composite image shows a ghostly ring of dark matter in the galaxy cluster Cl 0024+17. Credit: NASA, ESA, M.J. Jee and H. Ford (Johns Hopkins University) Roughly 80 percent of the mass of the universe is made up of material that scientists cannot directly observe. Known as dark matter, this bizarre ingredient does not emit light or energy.

Matter The great majority of ordinary matter in the universe is also unseen, since visible stars and gas inside galaxies and clusters account for less than 10% of the ordinary matter contribution to the mass-energy density of the universe.

- According to special relativity, c is the maximum speed at which all matter and hence information in the universe can travel. It is the speed at which all massless particles and changes of the associated fields (including electromagnetic radiation such as light and gravitational waves) travel in vacuum.

Dark matter The standard model of cosmology indicates that the total mass–energy of the universe contains 4.9% ordinary matter, 26.8% dark matter and 68.3% dark energy. Thus, dark matter constitutes 84.5% of total mass, while dark energy plus dark matter constitute 95.1% of total mass–energy content.

- The Universe is all of space and time (spacetime) and its contents,[12] which includes planets, moons, minor planets, stars, galaxies, the contents of intergalactic space and all matter and energy.[13][14] The size of the entire Universe is still unknown.[6]

What The most common state of matter in the universe is? The most common state of matter in the universe? Based on the volume of measurable matter in the visible universe, and using most postulates regarding the state of heavenly bodies as measured, matter is primarily in gaseou…s form (gas planets, stars, nebulae).

The Universe Empty? No, Filled With Neutrinos The void is an illusion. The universe is certainly not empty, that's a fact, but its not very dense either. Today, the visible universe consists mostly of empty space, void, while ordinary matter accounts for only 4 percent of the total mass. So where is the rest of 95 percent of the universe's mass? In dark energy and dark matter, according to some physical theories. Further still, the void doesn't seem to be so empty after all, but filled with an ocean of elementary sub-atomic and weakly interacting particles.

What is the Universe Made Of? Of this total density, we now (as of January 2013) know the breakdown to be: 1  4.6% Atoms. 2  24% Cold Dark Matter. 3  71.4% Dark Energy. 4  Fast moving neutrinos do not play a major role in the evolution of structure in the universe.

What is plasma as a state of matter? Plasma is a form of matter in which many of the electron s wander around freely among the nuclei of the atom s. Plasma has been called the fourth state of matter, the other three being solid, liquid, and gas. Normally, the electrons in a solid, liquid, or gaseous sample of matter stay with the same atomic nucleus.

Dark energy Nearly all inflation models predict that the total (matter+energy) density of the universe should be very close to the critical density. During the 1980s, most cosmological research focused on models with critical density in matter only, usually 95% cold dark matter and 5% ordinary matter (baryons).

What are dark matter and dark energy? It mapped the cosmic microwave background radiation and, in a shocking turn of events, revealed that atoms make up only 4.6 percent of the universe. The rest of the universe is far from empty, however. Dark matter accounts for 23.3 percent of the cosmos, and dark energy fills in 72.1 percent [source: NASA]. Together, these materials make up a whopping 95.4 percent of the universe, so no wonder we're still trying to figure out exactly what dark matter and dark energy actually are.

What is the Universe Made Of? Of this total density, we now (as of January 2013) know the breakdown to be: 1  4.6% Atoms. More than 95% of the energy density in the universe is in a form that has never been directly detected in the laboratory! 2  24% Cold Dark Matter.
