Bill Gates and Microsoft Fund Telescope
coondoggie writes "Bill Gates and the Charles Simonyi Fund for Arts and Sciences this week donated $30 million to an ambitious telescope that researchers say will be able to survey the entire sky every three nights — something never done before.
The Large Synoptic Survey Telescope (LSST) Project got $20 million from the Charles Simonyi Fund for Arts and Sciences and $10 million from Microsoft founder and chairman Bill Gates. Expected to see its "first light" in 2014, the 8.4-meter LSST will survey the entire visible sky deeply in multiple colors every week with its 3 billion-pixel digital camera, probing the mysteries of dark matter and dark energy and opening a movie-like window on objects that change or move. With the telescope scientists will be able to quickly find Earth-threatening asteroids and exploding stars called supernovas and will be able to map out 100 billion galaxies, according to researchers."

It might be arguable that it should, but the reality is that it never will.

The founders of the U.S. had a problem with taxation without representation, not taxation in general. As long as elected representatives have overseen taxation and government expenditure, all is running as intended. This Slashdot mentality of "This money is mine, and the government is just stealing it!" is just elitist dismissal of democracy, because you think you know better how money should be spent than your community. Plus, it's crazy to claim that the money is yours alone when, hey, there wouldn't be coinage without the government and they can determine what to do with it. If you don't like it, start bartering.
...not Bill Gates and Microsoft. Anybody making that misattribution clearly didn't even read the headline of the actual article, let alone the chunk of text quoted in the summary.
Only $30 million to look for planet-destroying rocks from outer space? Is that really all it takes to saveguard our species and world from such threats? If so, why aren't there half a dozen of these things already scanning the heavens every second of the day?
Gee, *humans*...
Galactic rotation curves are only one of the pieces of evidence of dark matter. There is also a lot of evidence due to weak lensing that there are large invisible mass distributions. The Bullet Cluster is an especially impressive observation of two clusters colliding. The shockwave from the baryonic gases smacking into each other has separated the hydrogen from the dark matter, as seen when you overlay the xray map and the mass distribution reconstructed with weak lensing. Modified theories of gravity can most easily explain discrepancies when the visible matter and apparent invisible matter are concentric (such as in rotation curves). Then you just need to tweak the radial force strength at large distance. But in a system like the bullet cluster, the visible and dark matter have been separated, and that's a lot harder to explain with modified gravity. (Not that people aren't trying, of course...)
Astronomers fought long and hard against dark matter, but grudgingly accepted it after it became more and more difficult to explain galactic rotation curves, weak lensing, the large scale structure of galactic clusters, and the power spectrum of variations in the cosmic microwave background without it. It all fits together much better when you introduce a very weakly interacting source of mass into the soup that makes up the universe. (Weakly interacting enough to become a nearly collisionless fluid early on during the expansion of the universe.) The smoking gun will be the detection of dark matter in a controlled lab setting. Those searches are just now beginning to ramp up.
