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 (XIII)

Let's kick off the new year with another set of questions from the great unwash- I mean, the interested, tax-paying public...

1) Do white holes and black holes have the same strength of gravity ?
Not really.

2) Where does matter falling into a black hole go ?
Into the hole. Just like with any other hole, really.

3) As the Universe expands and cools, will we see everything cooling so much it gets denser ?
No.

4) Do you have a nice graph showing how the Universe size varies over time ?
No, but I know some people who do.

5) Is NASA suppressing technologies better than rockets ?
No.

6) What's the best way to go high enough to see the curve of the Earth ?
A rocket.
