Come with me, if you will, to some state of omnipresence where you can sit on an enormous other-worldly sofa, watching the reality show that is planet Earth. (Just suspend disbelief and go with it. Cheers.)
This is like having a trillion tv channels….. but the main difference? You witness everything at the same time. The all-at-onceness of the big bang, your own demise, the end of the Earth, with everything and everynothing in between. It’s but one perspective, no matter how impossible to our finite minds. And from this particular vista, do you see time whizz by? Do you see it flow as events unfold? No. Because time (and its BFF-slash-identical twin, space) are static. They’re one and the same – and there’s no now. There’s no such thing as the present. That sentence just there? S’gone. Time-flow is an illusion, and no matter how you measure or record it, nothing changes. Spring forward and fall back? Nah. STILL nothing.
What’s YOUR now might not be someone else’s. Einstein said so, k?

If this is LIFE, THE UNIVERSE AND EVERYTHING as you look down upon it, then you can see that it’s all one. It’s static, and sure, it’s seen from an impossible vantage point outside space/time, but with the closing-off (never mind suspension) of your disbelief comes an OPEN MIND.

The block universe has been labelled a bit sucky, because it fails to represent the passage of time – time being one of our most fundamental experiences. But who says it’s an irrefutable model of reality anyway? That’s why the word THEORY is just so niiiiice. (Greek – Theoria: contemplation or speculation) And from theories, little baby offshoots are born – theolets, if you will – and like all good thoughts, they grow and grow until they hit puberty and reach A GREAT BIG HAIRY IDEA.
Logic tells us that indeterminate outcomes are governed/caused by (endless) probabilities in the “present”. (I’ll carry on calling it that for simplicity, even though there’s no such thing). Quantum objects exist in more than one state until we decide to measure ’em.
Because I’m feeling lazy, I’ll nick something from WIKI here, which pretty much sums it up:
“If the outcome of an event has not been observed, it exists in a state of ‘superposition’, which is something like being in all possible states at once….most quantum physicists now understand that the acts of ‘observation’ and ‘measurement’ must also be defined in quantum terms before the question makes sense. From this point of view, there is no ‘observer effect’, only one vastly entangled quantum system”.
Let’s pretend he’s Schrodinger’s Cat. Think of a considerably more upsetting version of Does-A-Falling-Tree-Make-A-Sound-If-Nobody’s-There-To-Hear-It and you’re halfway there. You could also call this “The Observer Effect” (not to be confused with the Uncertainty Principle) if you can’t be bothered trying to spell Schro..Shcro..
Take a cat. Any cat. Preferably one you don’t want any more. Perhaps even someone else’s mog. Box him up with a vial of poison (because the box alone is presumably not cruel enough) and shove in a radioactive source. Add into the mix an all-singing, all dancing monitor that can detect the decaying state of a single atom, at which point the vial is shattered, releasing the poison that takes out the cat. The Copenhagen interpretation implies that after a wee while, the cat is simultaneously alive and dead. Although logic would have it (DAMN THAT STUFF!), kitty can either be alive OR dead, never both, it’s just that we don’t OBSERVE and impact upon the outcome until it’s possibly too late for puss. This poses the question of when exactly quantum superposition ends and reality collapses into one possibility or t’other. When the box is opened, kitty, for all intents and purposes adopts one or other of his potential forms.
Now, let’s suppose you’re in a car, and even though you’re moving forwards at 80 miles per hour, you’re not wearing a seatbelt. (You must be a bit of a deathwishing dick, but whatever). Now, let’s suppose you crash. You twat yourself into that windscreen so hard that you come through and land on the bonnet. In bits. This is because you are ALSO travelling at 80 miles per hour – and when the vehicle stops, so, my friend, do you. But, depending on the witness and whether they can intervene, you might be indefinably dead and alive at the same time. Not until Schrodinger’s box is opened, or your remains are scraped from the car (or not) does the observer discover the outcome. If there are no witnesses, does the crash still happen? If the observer has intervening potential to change to the outcome, are you a cat in a box?
Why does this stuff give us brainache? Simple: because we have finite minds. And if we practice, we can surely eventually begin to tease some infinite thought out of those things. Ye cannae change the laws o’physics…..but we do have a choice how we interpret them. It’s a big ask, but even if we don’t have the answers, there’s nothing stopping us from asking the questions.
