Can anyone here answer a question in relativistic acceleration? My question is this: You have a space craft, from zero relative velocity, it starts accelerating at 1 standard g, 9.8 meters per second per second, and so forth.
If relativity was not a factor, it would reach the speed of light in about one year of such acceleration.
My question is, if at the start you feel your normal weight, like I weigh 100 Kg, later on in that year of acceleration when you start getting really close to c, say 0.9c, at that velocity, ship time makes you feel like you are going about 2X c. So at 0.9c, you would reach Alpha Centauri in about 2 years instead of 4.4 years. That would be onboard ship time, 4.4 years still goes by on Earth.
So when you are at 0.9c and still the craft is getting the same thrust it had at the start, if you had a scale, would you still weigh 100 Kg like you did at the start or would it be different now?
