Do photon's really need a couple of scientists teaching them how to travel the speed of light?

Great.

fantastic stuff.

Do they mean photons or the information encoded in the photons (spin etc)?

It's not useful to oversimplify findings then make obtuse claims... outside of storytelling where it inspires wonderful tales as per the above.

Now we can take out two prisms and watch cards and coins travel backwards in time.

Kregg...they DO need some help traveling FASTER than the speed of light...a hundred years from now I hope you remember this post...I'll be gone but you can reflect on your trip to Altair 4

Just read another article... a quantum tunneling effect they say. iffy at best I say when they claim it works over FEET instead of nanometers.

Uh Oh! you guys need a physicist here, luckily I just happen to have one.

No. The author of the article was either speaking out of turn, or the physicists, in an attempt to use layman's language got mis-stated. The other possibility is that someone lied. Teleportation does exist. I have seen the apparatus with my own eyes. It transports a photon in less time then we can measure (ie. instantaneously) from one place to another. The distance which I did not measure seemed to be about 2 feet, maybe a bit less. The problems comes in definition of terms. Transportation in this way does not travel! there is not speed at all because speed is defined as the distance traveled over the time it takes to get there. if you are teleported you did not travel, you were just here than there. No speed, no violation of the speed of light. If you want to do the math and divide say 1 meter by .0004 seconds (numbers are made up by me at random) you can do that, but that time was made up. The real time is zero, and to get a speed you would have to either divide by zero, and get no answer, or make up a very small number, which may have been what they did, and get a huge speed. This might explain a faster than light answer. I am not buying it. I will not say we will never see faster than light traveling. I am saying we won't see it for many years, and that is if we discover a whole new technology that no one can imagine yet. Cyclotrons get within 1 meter/second of the speed of light. Super coolers get within 1 degree of absolute zero. But some things are just not meant for humans.

I'm pretty sure this is _not_ the first "tunneling to beat c" experiment that's been done.

I'm pretty sure also that it's been shown that sort of thing does _not_ violate causality. That is, it does not allow information to actually get from A to B faster than c. the tunneling, I think, just reshapes the photon or something. (am I way off on this?)

Still not WARP speed . . .

Wel...at least they are working on it before certain uncivilised primitives take us back to the 15th century.

In our physical world we cannot travel the speed of light within a vehicle, we must become light. The first scientist who can separate a mixed cake batter, returning all of the ingredients to their original state, will be on to a real discovery.

Hey, they tried even back then with the black death.

Everything has to start somewhere. I think the first flight was something like 110 feet (or less).

Umm, before we all book passage to the other side of the universe, anybody remember "cold fusion"?
Message: Posted by: vinsmagic (Aug 19, 2007 12:52AM)
How about color fusion I just got back from alfa centuori
Message: Posted by: Cliffg37 (Aug 19, 2007 09:51AM)
Cold fusion isn't done yet. It was supposedly done in the laboratory once, but has not be repeated. It was either done by lairs or as a fluke. The number of people working on it suggests to me that if it is possible, it will eventually happen. Hot fusion is going well, with only one more major hurdle to cross before we get an incredibly powerful source of electric power. My guess would be we'll have the hot power within the next ten to twenty years. I believe this because I have see the work with my own eyes.

That's my point, Cliff.
I'm just saying it's probably premature to announce the toppling of the Special Theory of Relativity based on an 8 paragraph news article.

NRQM has offered "faster than light" phenomena since about the same time as Relativity was introduced. Whether its the phase velocity of a wave or the spooky action at a distance of "entangled" particles... nothing new.

What seems to keep the notion of large scale teleportation out of practical reality is more akin to the second law of thermodynamics and Heisenberg's Uncertainty principle. Remember that even a laser beam which is about a pinpoint in diameter when it leaves the earth will spread out to about five miles in diameter by the time it is reflected and gets back here. That's due to the simple quantum mechanics involved and not atmospheric distortion. Add in effects of our atmosphere and you can imagine how complex the simple pencil of coherent light gets on its trip there and back.
