Cosmologists believe about 20% of the total matter is made of regular — or “baryonic” matter — which includes stars, galaxies, atoms, and life, while about 80% is made of dark matter, whose mysterious nature is not yet known but may consist of some as-yet-undiscovered subatomic particle.

The observable universe is a ball-shaped region of the universe comprising all matter that can be observed from Earth or its space-based telescopes and exploratory probes at the present time; the electromagnetic radiation from these objects has had time to reach the Solar System and Earth since the beginning of the cosmological expansion.

As humbling as it sounds, normal matter almost certainly accounts for the smallest proportion of the Universe, somewhere between 1% and 10%. In the currently popular model of the Universe, 70% is thought to be dark energy, 25% dark matter and 5% normal matter. But ESA’s X-ray observatory, XMM-Newton, has returned new data about this content.

3 knowns and 3 unknowns about dark matter
Apr 11, 2022Figure 29.5.1 29.5. 1 and Table 29.5.1 29.5. 1 summarize the current best estimates of the contents of the universe. Luminous matter in stars and galaxies and neutrinos contributes about 1% of the mass required to reach critical density. Another 4% is mainly in the form of hydrogen and helium in the space between stars and in intergalactic

Observable Matter Makes Up About What Percentage Of The Universe
Apr 11, 2022Figure 29.5.1 29.5. 1 and Table 29.5.1 29.5. 1 summarize the current best estimates of the contents of the universe. Luminous matter in stars and galaxies and neutrinos contributes about 1% of the mass required to reach critical density. Another 4% is mainly in the form of hydrogen and helium in the space between stars and in intergalactic
Other than that, it is a complete mystery. But it is an important mystery. It turns out that roughly 68% of the universe is dark energy. Dark matter makes up about 27%. The rest – everything on Earth, everything ever observed with all of our instruments, all normal matter – adds up to less than 5% of the universe.
What is dark matter? A deep dive
The answer, published in The Astrophysical Journal on Monday, is that matter accounts for 31.5 percent—give or take 1.3 percent—of the total amount of matter and energy that make up the
