The current (albeit hotly debated) theory doesn't rule out particles that can move faster than light, but particles that can accelerate faster than light. Tachyons are theoretical particles that move faster than light, but they always move faster than light, and in fact can not slow down to subluminal speeds, much like how sublimuninal particles can not accerate to superluminal speeds.

Particles moving faster than light from a stationary frame of reference would have purely imaginary components to their Lorenz contraction and time dilation under special relativity. So WTF would THAT mean?

I see this is your first post. Even though I'm new here myself, allow me to welcome you. Smile

Indeed, welcome! Big Grin

Also, I'm a bit out of my league when it comes to discussing these things- but I'm fascinated. Please, keep up the discussion!

RE: Neutrinos traveling faster than light maybe be wrong
I'm anything but a science nerd, though it interests and fascinates me....I have a hard time wrapping my head around things....having said that, take what I say with a pound of salt, buuuut....

I just finished reading Carl Sagan's 'Cosmos' (written what? late 70's, early 80's?) in which he describes neutrinos as traveling faster than light.... so in light of that, I can't see why the head-scratching today? --->

EnLIGHTen me? Undecided

You sure you're not thinking of tachyons? Hypothetical particles that travel faster than light? Also, electrically charged particles can move faster than light in certain mediums, though not in vacuum. When that happens, you get the light equivalent of a sonic boom--Cherenkov radiation.

Mea Culpa

Really glad that book has an index! Sagan actually wrote that neutrinos travel at the speed of light. (page 186)

Forgive me for the intrusion and confusion. Oy. A pound of salt is right!

I'm not shocked by this. The media plays everything up (remember cold fusion occuing with Pons/Fleischman). I was looking forward to the follow up though. We go where the evidence leads unlike those locked into a preset game plan.

No offence to the Swiss but I had a relative who went there for an assignment. He hated it and said he much preferred Italy. I think his exact words were "I couldn't get outa there fast enough".

So I think the precedent has already been set.

So do you know how fast Uranus is traveling?

Don't worry, Val. You'll see it gets worse as we go along.
