: Has any direct, indisputable evidence been found for the existence of black holes? Obviously, no one will ever see a black hole due to its very nature.

YEs black holes exist one cannot see light escpe a black hole but light has been seen going into black holes. The gravity of a black hole is soo intence that stars can be "sucked" in . As a star gets closer to the horizon of a black hole it begins to move mutch faster. As its speed increases so does its temperature. All elements realaese colors when they become VERY hot. Stars have some of the highest concentrations of elements in the universe, the elements of stars have been seen by astronomers as they approach the black holes. The light that all elements give off is called a spectral emission, The sun is Yellow because the Hydrogen it burns at millions of degrees celcius is a yellow spectral emission. We can see black holes because we can see the stars that "fall' in to them.
