what evidence supports 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 dark matter made of antimatter? We know this because we would be able to detect baryonic clouds by their absorption of radiation passing through them. Third, dark matter is not antimatter, because we do not see the unique gamma rays that are produced when antimatter annihilates with matter.
What happens when dark matter meets matter? Dark matter particles can penetrate all other forms of matter, which means that they may even be able to traverse right through our planet without losing any energy whatsoever. On the other hand, their impact with ordinary matter that Earth is comprised of may hamper them slightly, resulting in a loss of energy.
Is dark matter attracted to ordinary matter? All particles of matter are attracted to each other through the force of gravity. Dark matter seems to be the “glue” holding galaxies together with all their ordinary matter, for the mass of ordinary matter alone is not enough. Galaxies would fly apart if not for the extra, dark mass.

what evidence supports the existence of dark matter? – Similar Questions
why do scientists think dark matter exists?
Yet, there is matter in the universe that does not emit light in any part of the electro-magnetic spectrum, which means that we cannot observe it with our telescopes. This unique property makes it impossible to observe these types of matter, so scientists call it dark matter.
Can dark matter be created or destroyed?
“One possibility is that there’s some kind of charge in nature, and dark matter is the lightest thing that carries that charge,” Toro says. In particle physics, charge must be conserved—meaning it cannot be created or destroyed. Take the decay of a muon, a heavier version of an electron.
Is alcohol a water?
Alcohols may be considered as organic derivatives of water (H2O) in which one of the hydrogen atoms has been replaced by an alkyl group, typically represented by R in organic structures. For example, in ethanol (or ethyl alcohol) the alkyl group is the ethyl group, ―CH2CH3.

Do most physicists believe in dark matter?

Can black holes destroy dark matter?
There’s the common notion that black holes suck in everything in the nearby vicinity by exerting a strong gravitational influence on the matter, energy, and space surrounding them.
How do you find the GHA and declination of stars?
Find the SHA of the star on the daily page and add that to the GHA of Aries. This gives you the GHA of the star that then can be combined with the assumed longitude to yield the LHA of the star. The declination of the star is found next to the SHA, and there is no d correction.
Is there anywhere on Earth where we can see the whole of the celestial sphere over the course of a day?
We can never observe the whole celestial sphere from the Earth, as the horizon limits our view of it. In fact, we can only ever observe half of the celestial sphere at any one time, and the half we observe depends on our position on the Earth’s surface.
