What is the Universe made of? The Universe is thought to consist of three types of substance: normal matter, 'dark matter' and 'dark energy'. Normal matter

Normal matter consists of atoms, which form the building stones to stars, planets, human beings and all other things visible in the universe. The exact definition of

Normal matter is the atoms that make up all cosmic objects in the universe, yet it accounts for the smallest proportion of the cosmos. Astronomers believe that about 20% of the total matter in the “To put that amount of matter in context, if all the matter in the universe were spread out evenly across space, it would correspond to an average mass density equal to only about six hydrogen atoms per cubic meter,” said first author Mohamed Abdullah, a graduate student in the UCR Department of Physics and Astronomy. In the standard Lambda-CDM model of cosmology, the total mass–energy of the universe contains 5% ordinary matter and energy, 27% dark matter and 68% of a form of energy known as dark energy. Thus, dark matter constitutes 85% of total mass, while dark energy plus dark matter constitute 95% of total mass–energy content. According to their calculations, normal matter and dark matter combined make up 31.5 percent of the matter-energy density of the universe. The remaining 68.5 percent is dark energy.

The created map stretches halfway back to the beginning of the Universe and shows how dark matter grew increasingly clumpy as it collapsed under gravity.

Another aspect that comes up when matter is discussed is something called antimatter. What results is a percentage—about 31.5 (plus or minus a margin of 1.3 percent standing in for the statistical certainty)—representing the amount of matter present in the mass of the universe. 2020-03-13 · While things like human beings, the Earth, the Sun, and everything that emits or absorbs light in space are all made out of normal matter — including particles like protons, neutrons, and electrons Arxiv – A Search for Warm / Hot Gas Filaments Between Pairs of SDSS Luminous Red Galaxies.

It has been theorized that the remaining regular matter must exist as a diffuse gas between galaxies. 2014-01-24 · If the dark matter is made mostly of MACHOs, then it is likely that baryonic matter does make up most of the mass of the universe. Supermassive Black Holes: these are thought to power distant "K" type quasars.

The Universe has several components. • Radiation. • Normal matter (protons, electrons, neutrinos, etc). • Dark matter. • Dark “energy”. They all contribute th the

That leaves Baryonic Matter – all the normal ‘stuff’ like you, me, the trees, the planets, and the stars – to make up just 5% of the Universe. But when astronomers look out into the sky, there In the modern universe, dark matter dominates the motions of stars in the outskirts of the Milky Way and other disk-shaped galaxies. But new research suggests that wasn’t the case 10 billion years ago. Instead, galaxies were dominated by the “normal” matter that makes up gas, dust, and stars—everything we can see and touch. Almost all of the universe — 96 percent — is invisible stuff called dark matter and dark energy.
