If acceleration is considered roughly, as moving through a body (at outer space with no gravity) at the speed of sound, is there any reason that when it (acceleration) gets to the other edge of the body, it will not turn back towards the first edge, still at the speed of sound (but weaker), just...

By coincidence i am reading just now 'Godel Escher Bach!...' Very interesting! i will try to learn the subject according to your further instructions and return if any questions come up. Thanks.

This book seems to be very rare - couldn't find even a summary of it, only a few library index references. Can't this incompatibility or disinterest between logics and physics measurements, be explained in simple words? A very basic explanation, the sort of explanations presented in popular...

Has such a mapping already been attempted in the past? If not, because it is not feasible, can you explain in more simple words, why it is not feasible?

Here is a question, that is so many levels above my analytical, logical, mathematical and physics skills (which sum up, in my case, to no more than popular science and science fiction reading), so the only reason that i am still asking this question, is that, not asking a question, seems to me...

Peter and Greg, I absolutely agree with your claims, on a up-to-date-realist thinking basis. P.S to my last post: "...that this is not a plastic **(or elastic)** deformity of the object..."

Peter, Gelilean principle of relativity is defined in such a way, as much as i understand it, that it says that if i want, i may check out with any existing experimental measuring device, an object body of matter, before it was accelerated (not while it is accelerated and certainly not with an...

Janus, If it is possible, please see the rest of the thread, after the first post above, and let me understand, how will the Gelilean principle of relativity, should be regarded, in case that in the future, by testing an object material, and without using an accelometer, it would be possible to...

Yes, but please try to recall, that this is an imaginary situation, that i am trying to bring up here, in order to understand things, not necessarily from a realistic point of view, but rather as a more fictional 'what if' scenario. What i am trying to imagine here, is that in a future...

I was thinking of a force which is not gravity (would that be called 'non-zero proper acceleration'?), for example the force that a rocket engine produce, in a section of space, where gravity can be considered negligible, how does this change the answer?

Hello Peter, and anyone else, who might help me understand questions, that pop up in my mind, and are probably situated somewhere between science, history of science, philosophy of science and science fiction. Let us assume something, much more crude and simple than the 'method' or 'measuring...

Yes, but when two forces are applied exactly once against the other (180 degrees), then they cancel each other, and one cannot trace them to the past (using current knowledge), or isn't it so? or even when two forces are applied one after the other, at different or even at the same direction...

Say that one day, there will exist a method to identify the amount and direction that forces were applied, on any given particle, since the time of the big bang, just like the rings inside a trunk of an old tree.. Would such a situation be exactly the same as saying, that ether was discovered...

Trying to put aside, somehow, questions of body elasticity, How long does it take on average for a body, in outer space, to start moving at constant speed, from the moment that force has stopped acting on it? Or is this question, totally dependent on elasticity, and if you don't take...

Ok, let's go back to static images! Attached is this diagram, please observe details. d is a very small distance, especially when comparing with the path that ligth beams take between clocks, even very small comparing to the horizontal difference of position between clock A and clock B. Clock...
