Bruce is right on the 1g acceleration- from the ship's point of view. As the ship gets nearer the speed of light, to an Earth- bound observer, it seems to almost cease to accelerate as it asymptotes to c. But from its own point of view, it keeps on accelerating.

Bruce may be right on that point. But it assumes perfect conditions, No drag, no inertia, and a light speed exhaust velocity.

That is certainly not the case with bussard ramjet. I just read Bruce's Wiki link. The 1978 the the bussard ramjet was rendered infeasible due to new data about interstellar hydrogen. There was some more work done in 1985, Bottom line, Our Aliens would have had to launch the fuel ahead of the their ship.

I think that perfect trip with constant 1 g acceleration is out of the question with any technology deemed feasible in our science.

Why do these Aliens hate Einstein?
