The seamlessness of consciousness implies a vast sharing that must be occurring among all human brains.
Of course the sharing is occurring with all living things and all matter everywhere.
In quantum physics, entanglement is the concept that a particle separated by great distance from another particle can remain entangled with it; poke one, the other instantly feels the poke, no matter where the two are in the Universe.
Einstein called it “spooky” and refused to believe that nature could be so unreasonable.
Yet there it is, still a cornerstone of quantum science.
Scientists are confounded by entanglement and don’t know what to do with it.
On the other hand, through the lens of consciousness, entanglement is pretty easy to grasp.
