Entanglement can best be understood as this: When subatomic matter is in a process together, subsequently the subatomic particles go apart from each other and go across the universe. When they do this, they will remain entangled. That means if you do something to one, the other one responds immediately, instantaneously.
The first time I kissed you. One kiss, and I was totally hooked. Addicted to you. I could never love anyone the way I love you. I'd follow you across the universe.
So if you ever felt something behind you, when you weren't even one, like welcome heat, like a bulb, like a sun, trying to shine right across the universe - it was me. Always me. It was me. It was me.
You're either on the bus or off the bus.
