Both have gone dark. Both are making announcements today at 5:00 EST. This could be big. A BloggoBlockbuster of some kind in the making.Maybe they have been having a secret affair all along and are moving to CA to get married!?!?!?Maybe they are starting their own blog, what with Phil being cosmic and Carl being more life sciencey, they could cover EVERYTHING.Maybe they’re coming out with a new Theory of Everything!!!Who knows?One thing I do know: I know where I’m going to be a five o-clock Eastern Standard Time today…… looking at The Loom and Bad Astronomy. (Hat tip on Phil’s announcement from TUIBG … Maybe Mike will have more observations later)UPDATE: What if this is linked to the Large Hadron Collider going on line?!?!?!?!?
