What possible threats do black holes pose to earth?
What is a black hole?
A black hole Is remanents of a former star. They are all over space, and if you went into one, you would go through a painful process of spagettification. (That is when you are so tight you go into a noodle shade to form and die) Black holes could pose potential danger to earth and other planets.
The sun dies out
In about 5 million years, the sun will die out and earth and all life forms in it will die. The sun will most likely form a black hole, because it's a star. This black hole will probably suck up earth and everything else in it.
