Follow the reluctant adventures in the life of a Welsh astrophysicist sent around the world for some reason, wherein I photograph potatoes and destroy galaxies in the name of science. And don't forget about my website, www.rhysy.net

Ask An Astronomer Anything At All About Astronomy (XLII)

Eclipse preparations are in full swing, which is why this post is completely and utterly out of the regular schedule.

1) Could the asteroid belt be the remains of an old planet ?
No.

2) Could ancient massive stars be the progenitors of supermassive black holes ?
Yes.

3) Nuclear bombs used as propulsion ? Are you serious ?
Of course I'm not. I'm not a bloody rocket scientist.

4) Surely we could make the asteroid planet thing work with a bit of imagination ?
Err, yeah, but it would still be the wrong answer.

5) How can tidal locking depend on the brightness of a star ?
Magic pixies.
