Another week, another batch of questions.
1) If the Moon eventually decides to leave (because it's slowly getting further away), will we be in trouble ?
It won't but we would.
2) OK well if it did leave could we replace it ?
Yes and no.
3) Why does every galaxy have a black hole at the centre ?
4) When black holes merge, do they form a wormhole ?
5) Does the Universe have limits ?
6) Is anyone researching wormholes ?
