MIT uses 10,000 ultracold atoms to settle 98-year debate between Einstein and Bohr

SMRTR summary

MIT physicists used 10,000 ultracold atoms to recreate the double-slit experiment, settling a 98-year-old debate between Einstein and Bohr about light's nature. By precisely controlling atomic "slits" and observing photon interactions, they confirmed Bohr's view that light exhibits wave-particle duality, but only one aspect can be observed at a time.
