Review # 2 was written on 2019-05-21 00:00:00 Isaac E. Young Middle School Supermassive Black Holes in the Universe. Well done discussion about the most powerful and least understood objects in the universe. Learned that there is a possibility that the universe itself is a black hole and that the end of everything, and meaning everything, is 10^98 (thats a 1 with 98 0's following) years away.
