On
Scott Peterson's first day on death row, two women called California's
San Quentin State Prison to say they were interested in marrying him,
according to prison officials. Prison spokesman Vernell Crittendon said about three dozen women called San Quentin with messages of support for the prison's newest bachelor, convicted and sentenced to die for the murder of his pregnant wife, Laci. "Two of them actually indicated to our staff that their purpose for calling was marriage," Crittendon told CNN. |

TAKE
our best understanding of gravity, apply it to the way galaxies spin,
and you'll quickly see the problem: the galaxies should be falling
apart. Galactic matter orbits around a central point because its mutual
gravitational attraction creates centripetal forces. But there is not
enough mass in the galaxies to produce the observed spin. Vera Rubin, an astronomer working at the Carnegie Institution's department of terrestrial magnetism in Washington DC, spotted this anomaly in the late 1970s. The best response from physicists was to suggest there is more stuff out there than we can see. The trouble was, nobody could explain what this "dark matter" was. And they still can't. Although researchers have made many suggestions about what kind of particles might make up dark matter, there is no consensus. It's an embarrassing hole in our understanding. Astronomical observations suggest that dark matter must make up about 90 per cent of the mass in the universe, yet we are astonishingly ignorant what that 90 per cent is. Maybe we can't work out what dark matter is because it doesn't actually exist. That's certainly the way Rubin would like it to turn out. "If I could have my pick, I would like to learn that Newton's laws must be modified in order to correctly describe gravitational interactions at large distances," she says. "That's more appealing than a universe filled with a new kind of sub-nuclear particle." |
* Gravity is not uniform.
* Gravity repulses at great distance. (Galaxies repulse each other into clumps.)
* Gravity is multiplicative, not additive.
* Space has some very minor friction to motion.
* Things just aren't as far away as they look. There is some function of light over great distance we just don't understand.
This is a really good article. I suggest you read the whole thing.
