Sorry for so many questions.
In Einsteins equivalence principle, it states that an observer in a close room at 1G accel would not know the difference between that or whether he was standing on the Earth. This makes fine sense to me. But it also states as well that it is independent of velocity.
The problem I'm wondering about is, the artificial force is created by the room's acceleration. Once the room stops accelerating, it will no longer generate this force. So, would you not eventually reach a speed limit? You would have to keep going faster and faster to keep up the force.
1. Imagine a main inside the room. The room is accelerating. The man feels a downward force.
2. Now, the man jumps up. The room is still accelerating, so the room comes up to meet him in the air. To the man, it appears he has fallen back down.
3. Now, the room stops accelerating, and just continues to move in a continuous velocity. The man jumps, but the room does not come to meet him, because now the man, and the room, are moving at the same velocity. In fact, the man is now moving at a higher velocity, since he jumped. He would move towards the ceiling of the room.
This is the problem I have with that illustration, anyway. The room would have to accelerate forever.
So if this is true, how can "warped spacetime" cause "constant acceleration"...so we are, in a sense, pushed into the Earth.
