- I thought Feynman said this. Anyway this doesn't mean it's going
- faster than light.

- Antimatter has positive mass; I can't remember if the
- experiments to test antimatter's gravitational acceleration by the
- Earth have yet succeeded, but if it had negative inertia it would
- (for example) curve the other way than expected in a bubble chamber
- in a magnetic field, not to mention that conservation of energy
- and momentum in particle reactions would be totally different.

- I'm sure this is a nice article and contains none of the misinformation
- above. Sorry to be rude, but if you don't really know what you are
- talking about please don't spread the ignorance around.

- Uh-huh, now I know why fusion research has so many problems!
