Universe Today Podcast

In this week's questions show, I wonder if it's cheaper to build things in space, if the Universe is expanding because it's rolling downhill, and do astronauts fart in space?

Notice that you haven’t been hearing much about black holes crashing into each other recently? That’s because the world’s most sensitive gravitational wave hunters have been offline for the last year.

Well, they're back now, with enough upgrades that they should be capable of finding a black hole merger every week, not to mention more colliding neutron stars, and maybe, just maybe, black holes eating neutron stars.

This week's guest is Geoff Notkin, the host of TV's Meteorite Men. He was recently elected to be the President of the National Space Society.
