"For example, what kind of mechanism could create a cloud of such enormous dimensions that does not coincide with any single galaxy or galaxy cluster? Is that same mechanism connected to the mysterious source of ultra high energy cosmic rays that come from beyond our galaxy?"<br /><br />The plasma cloud is located about 300 million light years away and is spread across a vast region of space known to contain several galaxies with supermassive black holes, or active galactic nuclei (AGN), embedded at their centers. The cloud might be evidence that AGNs convert and transfer their enormous gravitational prowess, by a yet-unknown process, into magnetic fields and cosmic rays that spread across the universe.<br /><br />The new finding could also help explain the unwanted and confusing "noise" scientists observe in the Cosmic Microwave Background (CMB), Kronberg said. The CMB is a ubiquitous radiation in the universe that is said to be a remnant of the Big Bang.<br /><br />The plasma cloud was discovered using the Arecibo radio telescope in Puerto Rico and the Dominion Radio Astrophysical Observatory (DRAO) in British Columbia.<br /><br />Maybe the calculations that try to use dark matter to explain the seeming problems in calculating the Universe should consider the effects of normal matter in, currently, undetectable amounts into the equation. <br /><br />Maybe it's not something di <div class="Discussion_UserSignature"> </div>

Grrr. This article states a nice discovery, but the author suggest dark matter doesn't exist. I had a nice long post going, but .. curiously, again, im auto-signed out in mid post....grrr. <div class="Discussion_UserSignature"> <em>"<font color="#333399">An organism at war with itself is a doomed organism." - Carl Sagan</font></em> </div>
