Removing blatantly wrong unsourced statement
"Despite of the general theory of the relativity and the cosmological models if there is a universal wavefunction of the universe, quantum theory therefore predicts the universe's evolution as the repetitive and infinite appearance of the big bang and big crunch (Big bounce and cyclic model) and so on as the global Poincaré recurrence."
this ridiculous claim is unsourced. The phenomenon described in the article, revival, has very strict necessary conditions that were not specified, with the exception of this one: "and let the energies be the rational fractions of some constant C". The conclusion that this property of nonrelativistic wavefunctions on particular domains with absolutely not general discrete spectra applies to the Universe is at the very least, laughable. I am taking the freedom of removing it, since it is unsourced.

Word salad
The striking consequence is that no finite-bit computer can propagate the numerical wave function accurately for the arbitrarily long time. If the processor number is n-bit long floating point number then the energy is[why?] for example 2.34576893 = 234576893/100000000 and is exactly rational[why?] and the full revival occurs for any wave function of any quantum system after the time which is its maximum exponent and so on that may not be true for all quantum systems or all stationary quantum systems undergo the full and exact revival numerically.
Not even wrong. What is even intended? 178.38.74.237 (talk) 20:47, 21 February 2015 (UTC)
