I personally think that the study of black holes is nessesary because that way we would know more about the galaxies outside of the earth.
I think that when scientists study black holes, they might find a way to know what place the enormous, gravatational, gap in space leads to.
This is a question that I’m also curious about, like, how is the land like in the hole, what is in it? etc.
So I really think that astronomers should study black holes and know more about it so that we could get more ideas about these huge holes.
