Dark Horse Challenges Dark Matter to Explain Missing Matter
MOND explains the rotation curves of galaxies extremely well; Dark
Matter explains the same things not so well. Dark Matter explains galactic cluster interactions extremely well; MOND explains the same things not so well. That's the long and short of it. /Dark Fields/ is an attempt to make MOND work better at the cluster level. There is a lot of cajoling needed to make Dark Matter work well within the galactic scale too. So it looks like neither theory works well outside their on size scale. SPACE.com -- Dark Horse Challenges Dark Matter to Explain Missing Matter "When applied to just galaxies, MOND can predict very well the behavior that astronomers observe. But when MOND is applied to larger structures like clusters of galaxies, it fails. To make MOND work for clusters, it must include more complicated concepts, such as entities called dark fields, which are different from dark matter, but work in a similar way to alter the amount of gravity present." http://www.space.com/scienceastronom...ng-matter.html Yousuf Khan |

Complete dark matter theory opens door to weight/energy potential(Dark matter is considered to be the top mystery in science today, solved,really.) And more finding on dark matter ebergy science from the 1930's. | [email protected] | Astronomy Misc | 0 | September 14th 08 03:03 AM |
Dark matter means ebergy (ebergy known since the 1930's to makeenergy from 'dark matter'). Dark matter is solved for the first time (100pages) | gb[_3_] | Astronomy Misc | 0 | August 5th 08 05:24 PM |
