The cosmological principle 4

Looking at the distant galaxies. What do you see and what results from it?

Looking at distant galaxies, we find that they represent a Universe not today.  After all, the light from them must have traveled towards us for a very long time - this is how it is explained today. Are these objects identical with those near us? Observations show that it is not.  The quasars, for example, are all billions of light-years away from us. They represent the universe billions of years younger. What does this indicate? Indicates the existence of evolution, the variability of the universe. It follows that a "strong" cosmological principle is not correct. [Says that the universe does not change, that is, time is not a factor in the description of the universe.] After all, we notice that further objects looks different: quasars - active galaxies - galaxies closest to us.  And no matter which direction we look. Indeed, background radiation properties also indicate the existence of evolution. Thanks to the discovery of this radiation in 1964 we already know that the universe is changing.

   If we were to observe the universe from the outside (is it possible?), we would find that the universe as a whole evolves the same everywhere.  We would get the impression of coordination, the same development everywhere despite the lack of any immediate connection between the parts (because of very large distances). The universe would look like a living organism. It's the impression. Simple, matter everywhere is the same and evolving at the same rate - at any scale: from the galaxies to atoms, elementary particles and deeper, of course proportional to the scale of the distance. There is no reason to be otherwise. All objects are equally distant in time from the common beginning.   In this sense one can speak of a global time, a time of the whole universe. Is it possible to measure time? Yes, it is possible. This is each observer's local time, because other objects, are delayed in time.  The universe, that's it all and is devoid of local features - is not part of a larger entity. The universe is all that exists as matter in the broadest sense.
