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?

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.
