Hi all, There are a few doubts I hope I can get enlightened. If we were in a lab in outer space, free of gravitational influence and the lab accelerates downwards, what will we experience? do we 'move' to the top of the lab? What I'm confused about also is, why is that when you have an acceleration of -g, in space, the lab experiences the same thing as if it was on the surface of the earth(motionless). Therefore, you cannot distinguish blah blah blah that whether you are accelerating upwards in space or under the influence of gravity. So abstract. argh.
