Join me on Shindig for an online interactive discussion

On Thursday, December 6, from 3:00 to 4:00 pm EST I will be conducting a live interactive discussion on Shindig about Edge of the Universe and cosmology.   It will be your chance to ask me  questions about dark matter, dark energy, the holographic principle, time travel, dark flow, black holes, the fate of the cosmos, or anything else you've ever wondered about the universe.  Join me with your text or video questions!
