so I was reading on spin states of photons.

So this book I was reading, of course without giving any explanation whatsoever, says that each photon has a spin state and that two photons given off from a decaying 0 spin state atom have a total of 0 spin... (conservation of mass + energy?)

And then it said that if you measure one photon's spin state the other's spin state is instantly set so that spin1 + spin2=0, even if they are really far apart.

And then it said something about that it isn't really a paradox of "nothing can go faster than light", just that the two photons are locked in superentanglement or something and are in the same two places at the same time.

--------------------

Well of course information is traveling faster than light, Mr. Dumb Book. If I somehow separate the photons far far away from each other without disturbing them (and measuring their spin states), I could combine one of them with an atom of known spin that needs one more electron to be more stable, and with that photon it becomes stable, or something.

So somehow I combine the photon with some known spin so that I don't get a random result when measuring its spin. Then the other photon is automatically the spin of what I just combined this photon with. (math)

Therefore I have just transferred information about the atom (that I just combined) instantly.

I could use a bunch of them to make an image, too.

So, why hasn't anyone done this before? Or mentioned it? Maybe they just forgot? Anyways, I have no idea how to isolate the photons, though. Or set up a predetermined spin for one atom to combine with an electron and a photon..or something..?

Yeah.

So?

No thing can travel the speed of light, but nothing can.

anything to do with information travelling faster than light. Photons (specifically, "dipole photons") are said to possess spin merely because when an atom making a dipole transition looses or gains angular momentum (depending on whether the transition is downwards or upwards). One conclusion from that is that you don't measure a photon's spin state without disturbing it. (It would have to interact with an atom, transferring it's energy to the atom and thus ceasing to exist as a photon. And by the way, that doesn't happen instantaneously.)

I once read something how someone proved that particles exist that can travel faster than the speed of light, but can't travel slower or something - like the speed of light is some kind of uncrossable barrior because of velocity's effect of time.

Their existence hasn't been proven, and couldn't be using any physics we're aware of. Someone once just described what properties such a particle would have to have to be able to exist in a state of motion faster than light. He wasn't saying the particles actually exist. But if they do exist, they would in fact have the same problem slowing down to the speed of light that we have speeding up to it. Anyone living in that "universe" would likely have the same beliefs about the reality of a state of motion below the speed of light that we have about the reality of a state of motion above it. (Getting ideas for a science fiction book yet? )

Well, my theory does conclude that tachyons turn people into raging, hulking, green monsters, but no one would publish my book for some reason...

I bet that Mr Bruce Banner is the only guy who supports your theory, Toonski.

"I like it!!"

Yeah, but the OTHER photon would instantaneously become the opposite of that photon which could be set up so that its spin would be equal to that atom. Right?

And, the thing about disturbing it.. maybe you could wrap it with some exotic particles or something? Keep it packaged? :/

when some other photon interacts with an atom, and what makes you think anything occurs instantaneously? And how does one change a photon's spin state? (If you're just going to make up concepts, you can get any answer you want. )
