Where can we find dark matter? The first variety is about 4.5 percent of the universe and is made of the familiar baryons (i.e., protons, neutrons, and atomic nuclei), which also make up the luminous stars and galaxies. Most of this baryonic dark matter is expected to exist in the form of gas in and between the galaxies.
Can we prove the existence of dark matter? Chandra X-ray Center, Cambridge, Mass. Dark matter and normal matter have been wrenched apart by the tremendous collision of two large clusters of galaxies. The discovery, using NASA’s Chandra X-ray Observatory and other telescopes, gives direct evidence for the existence of dark matter.
Is the center of the Milky Way dark matter? The center of the Milky Way could be dark matter instead of a supermassive black hole, according to a new study. The study is based on observations of the objects that orbit closest to the center. If it’s true, this could help explain how supermassive black holes originate.

what makes dark matter and dark energy?
In short, dark matter slows down the expansion of the universe, while dark energy speeds it up. Dark matter works like an attractive force — a kind of cosmic cement that holds our universe together. This is because dark matter does interact with gravity, but it doesn’t reflect, absorb, or emit light.
