I have always heard about dark matter, but I do not know what it means, what its uses are, and does it really exist?
In: Chemistry
The answer is no.
“Dark matter” is a placeholder name for what appears to be causing extra gravity in space. As far as we know, only matter can cause gravity, but there is no matter to be seen.
Why this extra gravity exists is not known. There is no direct evidence or proof for whatever is causing it. There are many theories and experiments to try to support these theories have been conducted, but so far, no experiment has delivered results.
