As ctdonath2 pointed out (I hope I'm paraphrasing correctly) nothing is really faster than the speed of light if you measure it against anything else in the same medium. It's only when you manipulate the medium of one test subject, in this case the light, that you can achieve this phenomenon. Now if I recall my lectures from nuclear power school correctly there is a theory about anti matter particles that travel faster than the speed of light, and therefore backwards in time. Of course you also have to ask questions like what particles have actual mass and which ones don't? Einstein theorized that an objects mass approaches the infinite as its speed approaches light speed (The "C" speed, not the retarded one).Then again, Einstein fought against quantum mechanics until his dying day. He was wrong about that one. He could be wrong about the mass / speed relationship at ludicrous speed.
Okay. That's enough, I'm going to have to go find a Mehgan McCain thread to lurk on now.
The mass / speed relationship holds at ludicrus speeds. It has been tested and Einstein was right.
Tachyons are the fanciful faster-than-light particles.
You want weird?
If you move slowly enough, the double-slit experiment will work regarding you going thru two doors.
Hmmm, interesting. That may be true, I don't know. However, I'm pretty sure we only see relativistic effects when something with mass approaches the speed of light in a vacuum.
