Title: Would information conveyance by quantum entanglemet break the speed of light
Post by: Petrochemicals on 26/11/2019 23:38:54
By binary or  other means of information transmittance, by forcing an entangled  particle into a state you would be able convey information. The technologies not there yet but just say for the sake of argument that alchemy was proved right in the end too. I know that there are lots of relativity issues with the following idea.

If you took one particle to a distance of one trillion light years at 0.99999c, taking just over one trillion years and then transmit information instantaniously through the particle by a  computer to the home particle, this would have not broken light speed.

Is the problem that the home particle could reply to this information could happen instantly plus computing time of a computer and thus information could be counter transmitted to the distant particle almost instantaniously ? This would give a transmission and reply time of just over one trillion years plus the two computing times rather than the 2 trillion for a standard question and reply.

However this does not give a faster than light travel as light meeting in the middle would be half a trillion years. (Can conveyance of information can be ~2C due to the fact that 2 parties are needed in an information exchange?)

Adding more questions and answers to quantum entanglement  will not  prove anything more than the information is most easily gained by travelling at the speed of light to the location(which of course is impossible)

If however a galactic blackhole supernova catastrophe where to occour travelling at ~1c, the distant particle could give one trillion years warning to the home particle of the event. Would this count  as information travelling faster than lightspeed? The information could have been faster obtained by direct travel, but does the fact that information has been conveyed to a location that has not travelled yet could have and thus has a 1 trillion light year buffer against the catastrophe mean that light speed has been broken. Is this not a question of material preservation rather than information ?

Simple point is that the particle has to travel before the information can be transmitted ?

You can't do that. If you retain the entanglement, the state is random. If you interact with the particle in an attempt to force it into a desired stated, you break the entanglement.
