Scientists at CERN’s Large Hadron Collider have made a discovery that could change everything we know about physics — a new exotic particle known as a tetraquark that appears to exist in two places at once. ⚛️ This strange behavior, known as quantum superposition, has long been observed in subatomic particles like electrons and photons, but never before at such a macroscopic scale. When researchers attempted to measure the tetraquark’s position, they detected it simultaneously in two different l
