Physics Nature Is Weird

Quantum mechanics might only make sense because we’re living in the overlap of two 'Twin Worlds' that mess with each other.

The Takeaway

Rather than treating quantum particles as abstract waves, this theory suggests reality is the overlap of two parallel worlds. Physical reality only occurs when events in both worlds align, which mathematically explains why particles seem to exist in multiple states until we look at them.

From the abstract

I introduce a novel realistic, stochastic approach to quantum mechanics by extending the recently proposed grabit formalism \cite{braun_stochastic_2022} to two Twin Worlds. According to the picture developed, we live at the intersection of two worlds with identical stochastic laws of evolution. Our World is limited to that intersection, and only coincidence events from the two Twin Worlds, post-selected automatically by our restriction to the intersection, have physical reality in Our World.
