New MIT Study Proves Quantum Theory Holds For Long Distances

Researchers at MIT have made large gains, for a field of science that studies extremely small particles.

Some of those tiny particles — called neutrinos — traveled from Illinois to Minnesota (a distance of about 450 miles) and, along the way, proved the idea of superposition, a property of the quantum theory, which scientists have only been able to prove thus far for extremely small distances.
