My husband is watching YouTube and there’s a man discussing quantum entanglement.
His description: There are two particles. They can be either green or red, but they are both colors until they’re measured. Once you measure one, though, it automatically determines that the other is the same. No matter how many times you measured, or how far you separated the particles, the two would always be the same color.
Why does one being one color guarantee that the other one would be? How do they “know” to always be that color? And what sort of implication does that have for science/real world, other than being really cool?

Quantum entanglement is pretty wild. Basically, you’ve got two particles that can be either green or red. But until you measure them, they’re both colors at the same time. Once you measure one and see it’s green, the other one will be green too, no matter how far apart they are. They’re linked in a way that if you know the state of one, you instantly know the state of the other.
Why this happens is still a bit mysterious, but it’s because they share a connected state. This has big implications like super secure communication (quantum cryptography) and super-fast computers (quantum computing). It also challenges our basic ideas about how the world works, showing that things can be connected in ways we can’t easily see or explain.
