Hi onifre (what happened to onfire?),
Do you see why an intelligent person could make an issue with your "isolated system"? It makes such a person ask:
Isolated from what?
It is self contained within the spacetime that IS the universe itself.
So then the universe is isolated from itself? Something isn't right here.
I'm holding out for parallel universes that intersect dimensionally. But I can assure you that I'm a cosmological lightweight. Who isn't? Nobody even knows yet what dark matter is or how much of it is out there.
I can see Lower Slobovia from my house.
