Astronomycast, your weekly fact-based guide through the cosmos. Hosted by Fraser Cain, the publisher of Universe Today, one of the most popular space and astronomy websites on the internet; and Dr. Pamela Gay, a professor of physics at Southern Illinois University Edwardsville. Episode 58: InflationWe 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 speck to become larger than the solar system, in a fraction of a second.

Hey, this is a mainstream podcast and a mainstream website. Don't assume it's bad science because of things I've been saying in other threads here.This podcast talks about how space-time theoretically expanded faster than the speed of light. They don't claim that the actual matter or energy itself traveled faster than light speed.Have a look at the topic of each past episode. Lately they've been going planet by planet and discussing what we know about each, and what current and upcoming missions are designed to study.

Why not start a thread in the Coffee House? I'd love to talk about this. It would make a nice change. As long as you don't get too heavy on the maths LOL.

If you like this Ned, then you might like these. I'm not sure if they are available as podcasts, but you can listen to them because they are archived on the "Listen Again" section of BBC Radio Four, which is similar to NPR in the US.
