Question

true or false (bonus points)

1. black holes are dark holes in space
2. all stars become black holes
3. all black holes are about same size
4. although supermassive, black holes move and spin
5. black holes are all black
6. black holes are cosmic vacuum that suck everything
7. once inside a black hole, nothing ever comes out
8. black holes become wormholes that connect universes
9. black holes do not die
10. humans can possibly create black holes that can destroy us all

Explanation:

1. Black holes are not just "dark holes"; they are regions with extremely strong gravitational fields.
2. Only massive stars (above a certain mass limit) can become black holes; not all stars.
3. Black holes come in different sizes (stellar - mass, supermassive, etc.).
4. Supermassive black holes do move and spin.
5. Black holes are not "all black" in the sense of simple color; their event horizons are regions from which light cannot escape.
6. Black holes do not "suck" like a vacuum; objects are pulled in due to gravity.
7. Once inside the event horizon, nothing (including light) can escape.
8. There is no evidence that black holes become wormholes connecting universes.
9. Black holes can "die" through Hawking radiation (in theory).
10. Human - made black holes (if possible) would be extremely small and decay quickly.
