Hugh Everett III formulated a new interpretation for quantum physics. It was eventually called the Many Worlds Interpretation, although not by Everett he called it a ‘relative state’ formulation. It is fairly simple to begin with and I am probably wrong on this (being pointed in the right direction would be great) but if you make a choice of say going left or right you actually do both at the same time. Just like the double-slit experiment where the photon or electron goes through both slits at the same time as long as nothing is observing it, even a camera.
So back to Everett. If you get to the end of a road, a t-junction say, you chose to go left but another ‘you’ is going right in a different world. So you are going left and right at the same time. If I am wrong on this I don’t mind being pointed out that I am so. To take it to the extreme, every action that is possible is being acted out in different worlds right down to the fundamental level of electron and photons.
This leads to a very interesting conclusion. Quantum suicide and Quantum Immortality. It is all to do with wave functions collapsing but if someone is shot dead in another world they survive so they are dead and alive at the same time. We are constantly avoiding death. Crossing the road, driving on a motorway, eating and choking, having a heart attack and surviving. Perhaps we never die because we are dodging death at every turn without knowing it. Yet we can witness others die. What becomes of us then? Do we reach 120 years old and find our cells stop reproducing and we just die of old age? So what happens to the brain? It can’t function without oxygen and glucose, but everything a human did in their life is stored there. Maybe in the future the brain could be tapped for information and brought back alive somehow. That has gone of on a tangent slightly, I’m just thinking out loud and utilising the creative writing training I have. Gone a bit sci-fi.
There are plenty of websites about Everett and his ideas. All very interesting.
