Last year, physicists at MIT, the University of Vienna, and
elsewhere provided strong support for quantum entanglement, the
seemingly distant idea that two particles, no matter how far away
of each other in space and time, can be inextricably linked, in one
way that defies the rules of classical physics. Take for example
two particles are on opposite edges of the universe. If she
are really entangled, then according to the theory of quantum
mechanics, their physical properties must be related in such a way
that every measurement made on one particle must be transferred immediately
information about any future measurement results of the other
particle – correlations that Einstein skeptically saw as "creepy"
remote action. "In the sixties, the physicist John Bell
calculated a theoretical limit above which such correlations must
have a quantum, instead of a classic, explanation. But what if
such correlations were not the result of quantum entanglement,
but…
