I thought wave function collapse was real under Copenhagen?

Ya, I'm talking about standard QM here; the Copenhagen interpretation. The universe tunelled into being? From what?! Also, if nothing collapsed the universe's wave-function, then it would still exist as a superposition. I'm talking about standard QM Though. If The Copenhagen...

Are you saying that if standard Quantum Mechanics (The Copenhagen interpretation) is true, then the universe cannot have a wave-function? What about objective collapse theories, like GRW or Penrose?

"Well we know decoherence causes apparent collapse." Yes, but by an outside system; what was outside the universe to collapse its wave-function? Also, if it is only "apparent", then this means that something like Bohmian mechanics, or the MW is true. If I am not mistaken, in standard (the...

This may be a bizarre question, but if the entire universe has a wave function, and wave function collapse for real (unlike in Bohmian mechanics or the Many Worlds interpretation), then what caused the collapse of the wave function of the universe? It must have been collapsed before we came...

Most say that a closed universe would collapse. Recent observations show that the universe will probably keep on expanding forever. Does this mean we cannot live in a closed universe? Or, is there a loop hole which allows a closed universe to expand forever?
