Einstein called it his biggest blunder. His early equations for general relativity accounted for a strange cosmic antigravity precisely balancing the attractive force of gravity. But after Edwin Hubble discovered that the universe is expanding, Einstein yanked the mysterious force from his equations. Several years ago though, UC Berkeley astronomer Alex Filippenko helped prove that Einstein was right after all. In fact, the magnitude of the antigravity effect is greater than Einstein had even thought. The universe is not only expanding, but it's speeding up every day. Why? And how fast? Filippenko is now asking those questions, using exploding stars as his cosmic mile markers.

That's one of my favorite areas of current research. I'm hopefully going to be writing a paper on it within the next month or so for one of my classes, assuming I get the topic I want. *crosses fingers*
