Gravity May Lose Its Pull
Man it's stuff like this that makes me think we know nothing. A lot of these discoveries turn out to be nothing, or only effective at the edges of the universe or in extreme situations like black holes. But there were a couple of recent discoveries [this as one, and the "anti-gravity" (the discovery that galaxies are moving away faster than they should be)] that make me feel like we still have things to discover. I wonder whether or not this will be useful in real life (would you like to drive your new anti-gravity car?) but some of this stuff could be so fundamental that it requires rewriting physics. Here's hoping!
