Question: why do you want to explore black hole ?

Because I’m fascinated by how gravity works. When you drop an apple (or your favourite type of fruit… I like apples), it falls to the ground due to gravity. This is because the earth creates this “gravitational field” which draws objects to its surface (or inner core). Black holes are really interesting to me since they are objects which have an insane amount of gravity. If you had a black hole which was the size of a golf ball then it would weigh the same as earth, so it would have the same gravity as earth. If you had a black hole which was roughly 3km across then it would be as heavy as the sun. Black holes are the densest and most destructive objects in the universe and they are the ultimate laboratories for testing ultra-high gravity! Gravity is what I essentially research… so black holes are natural test subjects =).
