Quantum entanglement is when two particles act together in an entangled system. This means that they behave like one object even though they are physically apart. It suggests that space is just the construct that gives the illusion that there are separate objects. Scientists all over the world have conducted experiments using particles like electrons, photons and even diamonds that interact physically together as one, but when separated, they behave as if they are still together. For example, if you spin one electron, the other electron will act in the exact same manner simultaneously, as if they are still physically connected. In our reality the universe is the entangled system, and everything in it is interconnected.
