Just a clarification: Antimatter and tachyons are not the same thing. Antimatter has positive mass and travels less than the speed of light (w/ possible exception of antineutrinos which travel at the speed of light). Antimatter is commonly observed in the lab, tachyons are not. Tachyons would have negative mass squared and thus imaginary mass. Steve Timm
