Dalespam, if the contracted space or particle has also time dilation or "fastness", that would mean all its phenomena have slowed down or accelerated by some factor- because the time rate effects to all physical processes. that would mean that observer o' can measure different F' than what...

NanakixIII i think my hitline question above is valid. "what is the theoretical basis of the assumption or fact that space do not contract in rest? does any accepted theory have anything to say to it? or is it a postulate?" am i right NanakixIII that You do a "categorical mistake" if you say...

let me write here my motivation for the question: -it is a known fact that space or a particle can contract when it has a relative motion. therefore it is reasonable to ask is it possible that the space or particle can contract under other conditions, for example: can it contract when...

to put the question in one hitline: "why the space or particle in its own rest reference frame DO NOT have contractions ,ever?" -what is the reason why space or particle do not have contractions or expansions in rest? is there a deep principle or fundamental reason why it does not have any...

**DanR please you don't have to remind me of my earlier post that are badly edited and frankly, piece of crap, and they should be deleted. why space don't ever contract other ways than in lorenz contraction? The lorenz contraction seem to be a weird single phenomenom of a relative particle or...

hi! i have asked about this issue, but i think i haven't got good answer to the question. can you help me, short answer would be good. its unclear to me still why there are length contractions or expansions other than lorenz contraction? Is there a theoretical principle or result that...

hi - i am curious about can you say directly a very good argument that isotropic length expansion can't exist in nature? i want to clarify this at first here. for example can atom at rest have isotropical length expansion or contraction? I mean does some very good argument deny this atoms...

according to special relativity theory, any object that has relative velocity also has lorenz- contraction L' = L0 *sqrt (1-(v/c^2)) it sounds odd that this is only kind of length contraction known to exist. why there are no other kind of length expansions or contractions, or are them...

hi! i am sorry about giving impression that i speculate over theories that are extremely well tested. everyone who is talking about science just have to be very humble to all scientific theories because they are extremely well tested in high precision in many kind of scientific experiments. i...

are there more exotic forms of length contractions? hi! do you mean that you can't think that empty space already full of infinite or very high number of empty inertial reference frames that have zero energy or very little energy and that they are moving at any speed from zero to c to all...

can inertial reference frame ever have "lenght contractions" in 3d or in rest? hi! thank you for all answers in this topic in previous threatin same topic. i open this new thread in same topic but here i try to keep the issue here very short and readable , with no speculation and concentrating...

hi! haell thank for the advice! i don't know about mathematics of affinity and other symmetries. have to check about these symmetries more i am not sure what do you mean. the wikipedia seems to have some information about these. i am not talking about selection of units, this is 3rd time i have...

hi! in special relativity, particles that are "inside" relativistic reference frame, has more momentum and also more energy, when they still travel at limited speed near c - and this energy can be very large - i don't know does it have theoretical limit. this gives the motivation to my...

quote: mfb You can just re-label all physical units and corresponding constants. If you do it consistently, you get the same physics again, but Earth has a diameter of 1 meter, light needs 20ns to go around, or whatever. All observers will agree on the physical predictions, and all but you will...

i add to the last "crazy sounding" sentense that if the mini-sized reference frame has also L^2 = 10^80 times less energy and therefore also 10^80 times less mass the idea of such things comes much more plausable. but can there be or is it possible in theory to have reference frames in...
