Does the wavefunction have a zero value anywhere?? Are there any places in the universe where a wavefunction has a 0 value? Or does the wavefunction have a non-zero value for everywhere in space? (0 doesn't equal incredibly unlikely). --- Also, let's assume the theory on the planck length is correct (perhaps it's been proven, I dunno I aint a physicist!), what happens if two particles collapse at the exact same moment -the same planck time slice - into the exact same place in space. Would there be some massive release of energy? Is there something inbuilt that stops this from ever occuring? Do we not know the answer to this at this point in time? I assume this can't happen as this would have inevitably happened in the electron cloud and we would have observed it by now.. right?
