• Resumen

  • The properties of particles aren't set in stone until you measure them, and their states can be entangled -- such that altering one affects the other much faster than light can travel between the two. There are loopholes in quantum theory, though. David Kaiser at the Massachusetts Institute of Technology and his colleagues are trying to close them down -- aided by starlight. Their experiment exploits a standard test for locality: Bell's inequality. It sets a limit on how often two entangled particles can end up in the same state just by chance -- without quantum mechanics or some unknown "hidden variables" to guide them.
