Quantum entanglement? (forgive me if dumb thought, quantum physics is magic to me)
Quantum entanglement can't transfer data. As soon as you try to use the connection you break it.
Quantum entanglement is like this - you have two sealed envelopes. In one envelope the letter A is written on a sheet of paper and the other has a sheet of paper with B written on it. No one knows who has which envelope until it is opened. All opening the envelope does is let you know what is written on the piece of paper the other person has. It transfers no data between the two points as the data was already set.
doesn't work, "reading" the entangled particles causes them to change state, thus you can't know if it changed as part of sending a message, or just because you were reading it.
There is no "sending" The data was set when the particles were entangled. All you're doing is moving a particle from point A to point B.
the data is still being "sent" according to the field of information sciences.
not that it changes anything about the physical impossibility
