We don’t understand entanglement
I left you a message.
You knew the message was coming. You also knew that you wouldn’t understand it. Not until you asked me.
The message came instantly from me to you. It didn’t come by radio or fiber cable at the speed of light. It was immediate. Yet, it told you nothing. You would have to ask me what it meant.
Here is the message:
“up”
I told you it made no sense.
I have a similar message. Mine says:
“right”
If we knew each other’s messages, we would know something important, something that, a century ago, nobody thought you could know.
That was until 1935, when Albert Einstein gave his two cents to a paper that would rock the small world of quantum physicists.
The problem is entanglement.
The paper was titled “Can quantum-mechanical description of physical reality be considered complete?”
Entanglement is a hard topic to understand, even for physicists. It is so difficult that nailing down exactly what it was and how it worked took decades. Still, nobody knows what it means.
Entanglement comes from conservation laws in physics.
