Re: RFC 6921 on Design Considerations for Faster-Than-Light (FTL) Communication

Bob,

thinking about this and assuming that the FTL Communication are deployed
in a not too far distant future, wouldn't we have started to receive
packets that was sent in the future already now?

communication times don't change if at least one communicator is not
moving in light speed.

My comment is that I think this RFC is not logical, and I don't
understand its recommendations. There is no way that a packet can be
received before send, packet-time never changes communicators-time
while the positions of both Tx and Rx are semi-fixed (change is
relative to communicators' times not their signal). I think the
communication-times may change when the communicators are at/above
speed of light not the signal/packet. Is my physics correct?

Only time will tell.
