Quantum entanglement has been demonstrated experimentally with photons, electrons, and even small diamonds.

There's a lot going on of late in the science of entanglement, including the now famous ER = EPR conjecture that Juan Maldacena posed to Leonard Susskind in 2013.

Wikipedia: https://en.wikipedia.org/wiki/...

ER = EPR is a conjecture in physics stating that two entangled particles (a so-called Einstein–Podolsky–Rosen or EPR pair) are connected by a wormhole (or Einstein–Rosen bridge) and is thought by some to be a basis for unifying general relativity and quantum mechanics into a theory of everything.

As you may know, a wormhole is a connection between two black holes that can be at any distance from one another. It's also used to deal with the apparent information loss at the event horizon of a black hole. According to contemporary theory, information is never lost, yet for some time that was thought to be occurring at the the event horizon.

A wormhole — a bridge connecting distant regions of the Universe — helps to shed light on the mystery of what happens to information about matter consumed by black holes.

This all suggests to me that everything is fundamentally one, and that entanglement is the arbiter of existence.

Call me a nutcase if you will. But I'd rather hear your reasoned assessment.
