If anyone wants proof that we have a long way to go in understanding the way the Universe works, look no further than entanglement. Einstein hated it. He called it “spooky action at a distance”, trying to prove with others that it was a flaw in the theory of quantum physics.
But it does work. And it has been proved to work time after time. And not only that, it works instantly, over vast distances. Entangle or “link’ two particles, change an aspect of one, and the other changes – instantly. Even though as Einstein showed, you cannot travel faster than the speed of light, disruption of entanglement is an instant process.
And physicists can’t explain it. Well, that’s not strictly true. There is one explanation, but it’s such a mind boggling explanation, that most people shy away from it.
The explanation – that everything is already connected! You, me, the stars, every atom in the whole Universe.
I rather like it!
