Dr Neil deGrasse Tyson

How can you not love this guy?  He makes science fun and I find myself getting lost in YouTube videos of him explaining the universe.  This time he answers a very improbable question, "What would happen if our sun just disappeared?"

Titanic is back in theaters, this time in 3-D!  You can check out where to see the film locally after the jump. James Cameron has mentioned he didn't add any new scenes or new dialog as other directors have done when movies get another theater run.  That doesn't mean the movie you'll see in theaters is exactly the same, however, although you'd have to be an astrophysicist to notice.
