Before the big bang, there was nothing. If nothing exists there is a contadiction in the inner logic of the universe, which causes things to exist. It didnt always exist. Nothing is everywhere and always existed and always will exist. Nothing is the ultimate contradiction, and in fact it is the "space" between the universes that can exist. There is no time in between the existence of the universes, simultaneously theres infinite time between them. The Universes are connected through nothing and thus they are seperated entirely from each other. Maybe there is an inernal contradiction in the laws of the universe, but it trys to be logically coherent. Thats the driving force of its internal workings. It wants to be logical, but ultimately it failed.from the beginning. Thats why we live in a world with an observer. A world without observer doesnt exist. Thus the universe inevitably creates a world with an observer to undo the contradicrion of there being nothing. The universe has an inner monologue. It has a consciousness. Heres a greentext.

This version of the liars paradox is the reason for quantum mechanics. If the particle cant be observed, it doesnt exist since existance is observability. The contradiction is a perfect random number generator. It either is true or false, but there is no probability that can be assignet to it producing a 1 or a 0. Thus it is perfectly random. It is neither deterministic nor indeterministic. It produces a certain distribution, which corresponds to the particles movements and leads to the wave function.
