Both particles are in a "fuzzy mix" of both states like a coin spinning in the air — heads AND tails at once ② THE SPOOKY PART 🅰 🅱 The moment A is measured, B "knows" instantly Even if they're galaxies apart. Einstein called it "spooky action" 👻 ③ BUT WAIT... send message You can NOT use it to send messages or cheat! The result is always random. You just know what the other got. eli5.cc

ELI5: quantum entanglement

high confidence
April 17, 2026science

// explanation

// eli5Imagine you have a pair of magic coins. When you flip one and it lands on heads, the other coin—no matter how far away—instantly lands on tails. They're connected in a special way so that what happens to one always relates to what happens to the other. That's similar to quantum entanglement, except with super tiny particles instead of coins [3][4].
