Viviane;-- in some european languages, the Universe is called the "ALL" like in 'World-ALL'
Good for them, we aren't speaking in some european languages, so it's utterly irrelevant to this discussion.
In much modern thought, our Universe /ALL is only a small part of the total. at least since 13.8 billion years ago. have 'a go' at it.
Absolutely and utterly wrong. If that were true, you wouldn't have had to claim (with no evidence, BTW) that what you are saying is true in some other language.
The universe is the cosmos. Within our space time, the cosmos is that is or was or ever will be. Period. Full stop.
There is an interesting parallel at the solar "surface": -- in one layer, the temperature is increasing with increasing heights. It is thought that magnetic or other waves account for this greater energy concentration.
Completely irrelevant to you trying to claim that the universe is only a small part of the universe and that we know what is outside our spacetime.
The detected gravity/ waves, vortices near the marble, could likewise originating in an earlier sequence, in times that predate the big bang, as opined some time ago, earlier, by Roger Penrose, the expert.
No, absolutely NOT. They did NOT discover gravity waves near the early marble of spacetime. Define what "time" you mean before spacetime existed. Without doing that, you are saying time happened before time happened. You clearly don't even understand what the discovery was, much less what it means, and certainly not what Roger Penrose meant.
