FYI physicists assume light and matter behave the same way "at the edge of the universe" as here.
so the same speed of light, chemistry of the elements "out and over there" as here at home.

If you were moving AT the speed of light AND if this speed were the maximum speed of anything, you technically would not be able to 'observe' anything because your constitution (the matter you are made up of) would also have every point in it translating in one direction, lacking the capacity to BE anything with dimensional functions. That is, you couldn't even have an atom existing at that speed because no electron, for instance, could translate sideways against that path around the nucleus without contradicting it to be at its maximum speed at all points.
Does expand “empty” space, is it diluting? The logic says not - empty space is growing, crystalizing. In case of dilutation all cosmology (constants) lost fixed base, it must be downgraded at the phenemenology, in fact... Another question: Does expand Einstein’s future (cone) too? Is not it already unlimited? Forget “expansion”, it is all such silly:(
Your translated English is hard to follow. But it sounds like a type of thought experiment Einstein did imagine. If you pretend that you are the only thing in the Universe, you have nothing to compare any 'speed' to. One can extend this to having two people. Using two skaters, for instance, might question if they are spinning with respect to each other. Can you infer they are 'spinning' or not? One proposal is to say you can if they are fully extended away from each other similar to the effects of a centrifuge.socrat44 wrote: ↑Sat Feb 23, 2019 8:59 am @Scott Mayers
one thought experiments :
you are swimming in a smock ocean and no
''matter-like or energy-like'' around you:
do you really swimming or it is only your dream ?
can you swim independently ?
P.S.
Light can ''swim'' independently.
Second Postulate of Special Relativity
The speed of light c is a constant,
and independent of the relative motion of the source.

No, the postulates are:
The first one is saying that for any subjective place of consistent observation one can be in, the physical laws appear to be equal to any other experience if one were in a different one. This is Galilean Relativity where Galileo recognized (or thought-experimented about) that if you are on a moving platform, like a train, when you toss a ball directly up in the air, to you it will fall down in the same apparent line you tossed it up in, regardless of your faster speed relative to the ground. This means you can predict that if the person on the ground were to toss the ball up in the air, he too would see the same phenomena relative to him. And this holds for a train that might be on some track of the roof the train moving. To those in such an imaginary train, those who repeated this experiment for themselves, would have the same relative result.1. First postulate (principle of relativity)
The laws of physics are the same in all inertial frames of reference.
2. Second postulate (invariance of c)
As measured in any inertial frame of reference, light is always propagated in empty space with a definite velocity c that is independent of the state of motion of the emitting body. Or: the speed of light in free space has the same value c in all inertial frames of reference.
