You've been over this at least once before, Marchi, and you continue to insist that the Big Bang was a conventional kind of explosion in which matter was expelled into a pre-existing space. That is not the way of it (according to "they"). The Big Bang was the origin of all our universe including space. That space expanded, carrying the contents with it. Which helps to account for the fact that, on the large scale (strings of galaxy superclusters), the universe looks to be much the same everywhere - taking into account the fact that we look into the past.

"They who are called they" also tell that the age of the universe is estimated to be about 13.7b yrs, not the 14.5b that you keep insisting on. You might as well get it right - heaven knows what will happen to your theories if you don't grin On the other hand, what's a billion yrs between friends?

You may have discovered by now that quasars have been identified as young galaxies. They appear young because we see them as they were billions of years ago. Those quasars might now be galaxies like the Milky Way. And in those galaxies may be astronomers observing the Milky Way as it was 10 billion yrs ago - possibly as a quasar.

What lies beyond the visible universe is, obviously, unknown; but as far as I know there's no reason to believe that it's different to the visible part. If it is the same, then it seems that 'at this moment' there would be no quasars.
