Re: Instantaneous Communications plus Time Dilation Equals ???
I would say that quantum entangled communications (QEC), which has a data transmission rate of X, the fastest that can be achieved, are linked even on the FTL drive based trip, assuming the FTL trip doesn't break the entanglement or have a time dilation factor. So, it ends up meaning that on the trip to destination 1, the data is transmitted to them both is the same, but when in the STL trip to destination 2, the datastream by the non-time dilated party would have to be slowed down to be understood by the ship by a factor equal to the rate of time dilation. So, if traveling 5 lightyears at .9c, the relativistic change factor is approximately 2.294 and would only be able to receive 2.18 years worth of data.
