What's quantum entanglement?

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 backdrop that gives the illusion that there are separate objects.

Scientists all over the world have conduced experiments using particles such as electrons, photons and even diamonds that interact physically together as one, but when separated, they behave as though they are still together.

For example if you spin one electron, the other electron will act in the exact same manner simultaneously, as though they are still physically connected.
