[quote=ASEI;1204856] SNIPPET.....Hmm - one thing that should happen normally in sublight SR travel is that the starfield should compress along the axis of your travel (rather than spread out). SNIPPET

ASEI. Right on the money. The other thing that happens is the Doppler shift of the encountered neutrino sea increases the cross-section there as the square of the velocity....giving a sense that you need more force to generate a given acceleration, or that your rest/inertial mass is increasing proportional to the square of the velocity. pete
