This, you would get into trouble when you realise atoms can be in more than 1 place at a time.
I alway think (however have no training or background) that this must be caused by the atoms / photons / what ever moving into another higher dimension and back out again, allowing instant travel (as we see it) between two points, as in the 2d world peice of paper / pencil thought exercise.
When 2 photons are entangled and properties are sent from one to the other faster than the speed of light it says to me that the information transfer must be happening via another dimension.
( I don't realyl know anything but its what pops into my mind when ilogical things like 1 atom two places and entanglement are talked about)
