Ask An Astronomer Anything At All About Astronomer (XX)

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 ?
They don't.

4) When black holes merge, do they form a wormhole ?

5) Does the Universe have limits ?

6) Is anyone researching wormholes ?
