if the real time zone is a copy of the physical world, what would happen to the real timetime zone or the other dimensions if the physical world was totally destroyed.

Well, the speculation is that the RTZ isn't in real-time, it just is closer to the energy signature of physical matter, and the "time" isn't real, because of reality fluctuations- You see stuff that used to be there, but isn't anymore, or sometimes see stuff that isn't there now but will in a few days. So my guess would be if there was no more physical reality (or material reality, it would depend if you mean total annhilation (via an entropic universal death), or destruction of the planet (supernova, meteor) or just the end of the species- you would possibly get a mix of whatever was there before and whatever is here now (if there is a now.) Now for universal death via entropy or even universal retraction, who knows- if there is no spacetime, then all bets are off.
Translation- Long winded 'I don't know'.

Even if our world was destroyed the RTZ would still be there and would even reflect Earth because it is close to the physical universe; not just earth.

Thanks, Sachiel.
