Dark Matter: All Wrong?

Dark Matter: All Wrong?
Larry O'Hanlon, Discovery News

Aug. 3, 2007 — The mysterious dark matter that's been called on to make sense of the ways galaxies twirl through space may not exist, if an alternative theory is right.

But there is another radically different possibility: What if gravity itself doesn't work quite the way we think? Maybe at the outer edges of galaxies where the gravitational acceleration — the g — of a galaxy is extremely small, gravity tugs just a tad bit more.

I saw a show on PBS once that talked about Dark Matter and Dark Energy. It was fascinating stuff. Now with this new theory there's even more to dig up. Science is really fun.
