Astronomers Make Important Dark Matter Discovery 223
saudadelinux writes "To quote a press release on NASA's site, astronomers using the Chandra X-ray Observatory have discovered 'how dark and normal matter have been forced apart in an extraordinarily energetic collision.' There will be a briefing at noon, August 21 ET, on this discovery, with streaming media provided by NASA, and some details of the research posted on Harvard's Chandra site just beforehand."

Isn't dark matter just all the none illuminated items in the universe?
Rocks and stones and humans and plants and animals and silicon and paper and all these things are what I would consider dark matter, I might be wrong but someone could add some illumination on the subject I would be most grateful.

Wonder what Mordehai Milgrom will be saying (Score:2, Interesting)
In the August 2006 Discover magazine, there was an interesting piece about Mordehai Milgrom, a physicist who does not accept the dark matter theory. Basically, he has been able to retrofit Newton's equations to allow them to predict on the galactic scale (one of the reasons for the belief in dark matter). Being only an amateur physicist, I can't tell which method is the simpler, the one that only changes the equations, but (almost) no one buys, or the one that postulates the existence of matter that absorbs all electromagnetic energy. I can't wait to hear what this press release tells us.
