Acceleration in a Closed Box: Uniform or Varied?

[Buckleymanor]

I can't speak for Mike, but I assume he means is that we (Bob) remove the box and its contained observer (Alice) to a (hypothetical) gravity-free region (yes I know that's impossible), but we don't tell Alice we did that (we are very sneaky Bobs). We also give Alice a powerful sedative before we turn on the drive (which is an extra-sneaky quiet drive), so she wakes up and says:

"Hey! I'm in a gravity field! My rocket ship must have landed on a distant planet!"
​

Now, I know I've given enough rope for you to hang me with, but please don't hang the others.

That's pretty good danR so long as the acceleration was constant.I doubt there are many regions in space where your weight changes.

Yes, it will feel like you fell on the ground, or jumped off a building, etc.

That was the point if you were stood in the box and you felt like you fell or jumped then you would know you were being accelerated and not in a gravity fied. People standing in a gravity field don't genrally fall to the ground.The acceleration would have to be uniform and constant to avoid this.

No. You’re changing things around.

When I said you will feel like you fell on the ground, or jumped off a building, I was directly responding to your question about objects subjected to violent or sudden acceleration, not constant acceleration. Please look at the second part of post #2. I clearly quoted your comment and responded to it. How is it possible for you to have misunderstood this?

Anyway, I’m kind of dense. It took me way too long to realize that participation in this thread is pointless. I am unsubscribing.

Einstein was one of the smartest people in history. He was a genius among geniuses, and as smart as he was, he spent 10 years developing the general theory of relativity. Now out of all the brilliant scientists in the last 100 years, no one has seen the flaw with Einstein’s idea of the equivalence principle except you. Congratulations. I do wish you the best in your endeavors.

Sorry you feel that way Mike. I don't imagine Einstein's theory of equivalence is in much danger of being refuted.However I can't see the problem in questioning it if it helps to understand more about it.If you don't ask you don't learn and someone who has never made a mistake has never done anything.

And by the way I did not misunderstand this put in context with your first answer.

Yes, this is always the case.

You are reinforcing your pre-concieved assumpton by replying with.

There is no mention whatsoever about constant acceleration or otherwise.
