There are a number of interpretations of the seemingly strange world of quantum mechanics. All versions are mathematically valid and we can't say or rightly guess which is correct:
- The "many worlds" interpretation says that, whenever two possibilities exist, then the universe splits and both possibilities live out.
- The "Copenhagen" interpretation says that no outcome is present until a conscious observer looks in. (This is the most widely accepted view in both the fields of real science and, quite by contrast, new age mysticism).
- The "pilot wave" interpretation says that there is no 'weirdness' and the world is entirely deterministic. Yet to do this it says that there is a little hidden weirdness to the maths. (Though deterministic, this is one of the least favoured by scientists).
There are many more interpretations, but my favourite was recently brought to my attention and it is this:
- The "zero worlds" interpretation. That the quantum world (that we do not intuitively understand) brought about the classical world that we believe we are within (and so naturally understand). The universe as we see it is classical and so thereby ungraspable as our mind and tools are classical, but the truth we must reach is quantum. That there is no universe at all is a magical perspective and one that my mind and intuition love.
