Black holes are some of the most exotic objects in the universe. They are the final evolutionary stage of giant stars much larger than the sun. When these stars explode, their cores collapse down to the size of large asteroid. That produces gravitational fields so intense that not even light can escape, reaching a point where space and time as we know them cease to exist.
