why we should believe in black holes?
- We know that black holes exist from the space that's affected around them.
- Scientists look at gas and dust in an area that they think is being effected by a black hole. The gas and dust will be super heated, so it gives off electromagnetic radiation.
- Although black holes cannot be seen by the naked eye, scientists can see the the xrays of the outer layers of a star being burned off as the star approaches the black hole.
