We interrupt this tour through the solar system to bring you a special show to deal with one of our most complicated subjects: the big bang. Specifically, how it’s possible that the universe could have expanded faster than the speed of light. The theory is called the inflationary theory, and the evidence is mounting to support it. Einstein said that nothing can move faster than the speed of light, and yet astronomers think the universe expanded from a microscopic spec to become larger than the solar system, in a fraction of a second.

Ep. 57: Jupiter's Moons
Last week we talked about Jupiter and we could sense right away it would be too much to handle. This week, we’ll talk about Jupiter’s moons – how many are there? What makes them so interesting? Is it true that the most likely place in the solar system to find life (other than Earth) is actually on one of Jupiter’s moons? Hang on tight. We’re going to cover a lot.
Ep. 56: Jupiter
Last week we talked about rubble, this week we’re going to dig into the largest planet in the Solar System: Jupiter, but will it all just be hot gas? There’s so much to talk about, we’ve decided to break this up into two shows. This week we’re going to just talk about Jupiter, and then next week, we’re going to cover its moons.
Ep. 55: The Asteroid Belt
In the last few weeks we’ve had many emails saying that our tour of the solar system would not be complete without a show on the asteroid belt. Your wish is our command! We talked about Mars in episode 52, and now that we’re back on track our next stop is the asteroid belt.
