From: "Eric Funk"
I've never designed a vehicle, so I may comment may not carry any
weight, but if you design a ship with a Delta-Vee of 10 meters/sec
This should be "acceleration"; a ship with 10 m/s delta vee won't be
able to leave orbit, let alone reach a star.
(i.e. 1G, as in no need for artificial gravity to the human
occupants) and spend half your trip accelerating 1G and the other
half decelerating at 1G, you can get from here to the galactic
center in a human lifetime AS FAR AS THE OCCUPANTS are concerned,
due to time dilation.
This gets increasingly difficult as you approach c as the ship effectively
gains mass, so the ship's acceleration diminishes...
Within the ship's reference frame, observed mass and therefore
acceleration remains the same.
Outside the ship, its mass increases, but the reaction mass's mass also
increases. Observed acceleration will still diminish due to time
dilation, though.
