Are dark matter and dark energy: energy?
Yes, could you explain to me what is dark matter?
Certainly. Dark matter is a type of matter that is believed to be present in the universe, but it doesn't interact with light, so it's essentially invisible. Scientists have observed that galaxies rotate much faster than they should, according to the laws of physics, and dark matter is believed to account for this discrepancy.
