The Fabric of the Cosmos

For a fascinating and accessible look at the weird and wonderful world of cutting edge physics and cosmology, check out the new NOVA TV series The Fabric of the Cosmos (website) that starts tonight on US PBS stations. The series is based on the book of the same name by Columbia University physics professor Brian Greene. The first episode, What is Space, can be viewed on the website. It looks at the nature of space, and explains it as “a dynamic fabric that can stretch, twist, warp, and ripple under the influence of gravity.” And then there’s that whole “dark energy” thing, the stuff that physicists think makes up 70 percent of the universe, but no one really knows what it is. If you’ve been wondering why physicists think it’s there, this is a good place to start.

If you have an iPhone, iPad or iPod Touch, you can also watch the series via the PBS app.

As part of the lead-up to the first episode, you can ask questions about the series on the World Science Festival Facebook page.  And at 10 pm Eastern time you can watch a live Q&A hosted webcast hosted by Greene with fellow physicists Leonard Susskind and Nobel Prize winner Saul Perlmutter.
