    I would be interested to know what the relationship is between the absolute nature of the speed of light and the indeterminate nature of Heisenberg’s uncertainty principle.

    If an object is moving at very near to the speed of light, does the uncertainty principle impose any “fuzziness” on the consistency of the speed of light? Or does the speed of light impose any restrictions on the uncertainty principle?
    I find it hard to describe the question well, but I think it boils down to this: can any of an object’s many superpositions involve faster than light travel?

    I suspect this is a non-issue, but I would be interested to know why.

    It is not clear exactly how these would be related. Although, things like tunnelling (e.g. an electron through an insulator or potential barrier) can occur faster than light. And that is because it doesn't actually move from one side to the other, but its probability distribution allows it to be either side of the barrier. Which is (I think) related to the uncertainty in its position. But this cannot be used to transfer any information faster than light, because you can only tell that tunnelling occurred after the fact.
    You can do everything right, strictly according to procedure, on the ocean and it'll still kill you, but if you're a good navigator at least you'll know where you were when you died.

    Thanks. So if no information is transferred then faster than light travel is possible (Einstein’s spooky action at a distance). But in this particular instance where information is transferred the situation is not clear.
    That’s interesting. If it’s not exactly clear how these two would be related then could this be resolved by an experiment? Surely someone has thought of this? I would have thought that Physicists would have been champing at the leash to be able to check out conflicts between relativity and quantum physics? Or would such an experiment be beyond our means technically?
