"When somebody sounds like a total fucking crackpot, they almost always are."

Aristarchus of Samos sounded like a total fucking crackpot, and if you had called him out your prediction would have been right - for a couple millennia.

What if instead of taking your attitude, the Greeks had devoted their energy to developing better sensors to test Aristarchus's claims about the parallax motion of the stars? Instead of sitting around calling him a crackpot, we could have had an accepted heliocentric model of the solar system some 1800 years before Copernicus.

I just saw this article on today's front page:

http://science.slashdot.org/st...

The EM drive is controversial in that it appears to violate conventional physics and the law of conservation of momentum; the engine, invented by British scientist Roger Sawyer, converts electric power to thrust without the need for any propellant by bouncing microwaves within a closed container. So, with no expulsion of propellant, thereâ(TM)s nothing to balance the change in the spacecraftâ(TM)s momentum during acceleration.

No, science has never disproved the aether. It was ruled out for social reasons. When that social reality changes, science will probably bring it back. Yves Couder's experiments with silicon "walkers" bouncing on a liquid substrate, with which he can recreate Young's double-slit experiment on a macroscopic scale, would fit nicely with aether theory. But that fit is ignored by physics, because of the social ramifications of bringing back aether theory.

Gee, Toto, I don't think we're in Kansas anymore.
