“They left out the biggest puzzle of all: what is the mechanism underpinning Quantum Entanglement?”
Back long ago when I was studying quantum mechanics we were taught that none of it made any intuitive sense, but that the math worked and we just had to accept it.
The exciting work that got the Nobel today helps reframe quantum mechanics as a branch of information theory. If you think of the universe as a computer then quantum mechanics is the simplest way for it to be coded.
Entanglement is the simple idea that everything can be left undefined until needed. Only when a particle is observed does its exact nature need to be generated.
I suspect one of two possibilities for dark matter. The first is neutrinos that have slowed down and orbit with everything else. The other is that our three dimensional universe is stacked with other three dimensional universes in a larger dimensional superverse. Only gravity reach’s between between them which is why it is so weak compared to the other forces.
