There is no law that says that information can not travel faster than light is there? The law is just a out mass/energy.
On top of that I believe faster than light transfer of information has already been experimentally shown to exist.
- pdonis 13y ago> There is no law that says that information can not travel faster than light is there? Yes, there is. Information has to be carried by some form of mass/energy, so if mass/energy can't travel faster than light, neither can information. > I believe faster than light transfer of information has already been experimentally shown to exist. No, it hasn't. If you're thinking of the CERN neutrino experiments a couple of years ago, that turned out to be an equipment error.
- mschuster91 13y agoHmmm... shouldn't two linked quantum particles change their state in sync, no matter the distance?
- legulere 13y agoYou can't transport information through quantum entanglement.
- mdemare 13y agoI don't think so; see: http://lesswrong.com/lw/q2/spooky_action_at_a_distance_the_nocommunication/ http://lesswrong.com/lw/q2/spooky_action_at_a_distance_the_n...
- pdonis 13y agoIt's worth noting that the full explanation given here assumes that the many-worlds interpretation is correct, which not all physicists would agree with. But the "no-communication theorem" is true independently of which interpretation of QM you adopt.
- pdonis 13y agoThis is a non-relativistic description. The correct relativistic description assigns quantum field operators to events in spacetime, and operators at spacelike separated events commute--i.e., they give the same results regardless of which order they occur in. So there is no physical fact of the matter about the order in which the particles "change state".
