Surely this violates the Principle of Equivalence? The crew of such a spacecraft should feel precisely the same effects as the crew of a motionless spacecraft sitting in a homogeneous gravitational field of 1g - viz a constant g. No? |
The crew of the accelerated spacecraft may feel that they were accelerating at 9.8 m/sec**2, the outside observer would see the acceleration taper off, asymptotically approaching zero as the spaceship approaches c.
