You can ask yourself, what if all of that was unnecessary?
This whole idea that we need a separate rule for what happens when we measure something.
What if you just erase that from the rules of quantum mechanics?
And the answer is that what you find is that every possible measurement outcome comes true, but in a different world, in a different part of the overall quantum universe, you get parallel worlds where different measurement outcomes are true.
That's when I asked what the guy was smoking.
If you have an iPhone, you can download an app called Universe Splitter.
And if you're ever stuck on what decision to make, should I have a hamburger, should I have pizza for dinner tonight or whatever, ask the universe splitter and it will come back with an answer.
And you can be guaranteed that there's a whole other universe which you can never interact with or talk to in which you do the opposite thing.
In that instant, yes.
At the decision instant.
It's a physical quantum process.
This is not anything that we bump into in our everyday lives.
If it doesn't make you a little bit uncomfortable, you're not taking it seriously.
