What is quantum entanglement?

529 viewsOtherPhysics

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?

At some point in time it is determined that two particles have the same “vibe” and it stays that way forever no matter how far apart they go. Kind of like soulmates 🫶🏼
