Electrons are fuzzy things, not pinpointable because they don't really live like that - they zing their way round and through several dimensions at once and somehow land up here long enough to fend off the pesky Positrons. So not being able to pin down an electron, which is where this whole uncertainty-principle thing first started, is one thing. Not being able to pin down anything at all is more like it.
Look at the bigger picture - the Multiverse. Almost everyone agrees with Everett now that quantum mechanics has proved so many dimensions and variables to exist. That's a lot of Universes, mind, and a lot of options, probably stretching to Infinity if we could bring ourselves to face it, but Renormalisation is easier so..... back to the comfort zone. What for? Who doesn't want to know how to get the best out of what they've got? Money doesn't come into it - there are as many tragic, desperate and depressed stars as there are happy-go-lucky ones, just as everywhere else in society. But we do share something that's a bit different to our predecessors, and that's a grounding in how it feels to be waking up.
What if we, like the electron, are buzzing in and out of Multiversal states all the time, without realising it? How can every thing be unique if there are not infinite proportions to choose from? And that, extrapolated into our neural framework, means that we are freer to choose or not to choose than we were before, because knowing that both are necessary for our movement through Time allows us the pleasure of appreciation, the feeling of what it is to be happy with yourself, instead of beating ourselves up and crashing back into the pan of Past/Future Anxiety where everything loses its own plot.
If we can be in so many places at once then why shouldn't identical snowflakes fall where no-one is watching them, and identical grains of sand appear in remote corners of the world where they can't be found? The commonality is the thing, in the rarity of symmetry, because nowadays Nature is not fond of symmetry and scientists have long hated that.
Back to Charnia, where the lions and witches had us wondering about our wardrobes..... but if you want Wiki's take it's right there behind the picture, where Life first began to take Form....
