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 (XXXVII)

At the last minute the threshold of five questions was reached for publishing a "weekly" AAAAAAAA, so here it is.


1) Could we use Lagrangian points to move around the Solar System ?
No. Well, yes, but they only take us to Narnia, and who wants to go there ? No-one, that's who.

2) Can we work out the speed of the meteor that killed the dinosaurs ?
Yes but badly.

3) How can we build a gravity rocket ?
Just badly.

4) Are these ionised gas clouds evidence of galaxy destruction ?
Maybe !

5) Do some interactions in galaxy cluster dominate over others ?
Usually not.
