This week we wanted to give you a basic physics lesson. This isn’t easy physics, this is a lesson on the basic numbers of the Universe. Each of these numbers define a key aspect of our Universe. If they had different values, the Universe would be a changed place, and life here on Earth would never have arisen.

Listener Survey
Thank you for your interest in the survey, but we have completed gathering data. If you would like to see the results of this survey, check out our paper in Communicating Astronomy with the Public
It’s time to answer questions again, but this time we hope that you’ll take a minute and answer ours. We’ve written a brief survey that we hope you’ll take a minute to fill out. This survey will allow us to collect some general demographic information about our audience so we can make the show even better. We promise it doesn’t even ask your email address – and, if you fill it out, we’ll give you a link to a special, full-length episode that does not appear on our feed.
So please, please – do us a favour, and fill out our listener survey
Ep. 44: Einstein's Theory of General Relativity
If you remember way back to Episode 9, we covered Einstein’s Theory of Special Relativity. Well, that’s only half of the relativity picture. The great scientist made an even more profound impact on physics with his theory of general relativity, replacing Newton with a better model for gravity.
Ep. 43: Questions Show #5
It’s time to answer the questions again. And this time we’ve got some doozies. Is the Universe rotating? Is space something, or is it nothing? Is dark energy evenly distributed? What would happen if an astronaut went out the airlock, without a spacesuit. Want to know the answers? Well, you’ve got to listen.
