Oh My gosh! It's Kelly Link! The awardwinning Author of my favourite short story "Magic for Beginners"!!! You can download some of her stories for free, and even listen to them on the internet.
Anyway, we're talking about superfluids today. What's a superfluid? Well. It's what you get when you cool helium down really cold. It has strange properties. Watch some videos on it, if you have time... It might help.
Fiona and Jocelyn are back to help me explain. well. try to explain.

Today's Show is Awesome because our guest is TED LEO! the guy from the intro-song (Tell Balgeary, Balgury is Dead)! I bring together Vicky Scowcroft and Mike Zemcov and we talk about how GIANT SOUND WAVES which rang through the universe at a time before recombination (like.. 13+ billion years ago) provided that seeds for gravitational collapse. as a result, the size of these sound waves explain the size of the largest "objects" in the universe: gravitational super clusters! They also explain why there's nothing bigger.
It turns out that before there was any differentiation at all, there was music.
ROCK ON TED LEO!
ROCK ON TIPHYTERS!
(P.S. there's a couple rad conversations after the end music. that Ted Leo is a smart guy.)
