ONE of the most troubling features of quantum mechanics, the theory that
describes the world of atoms, is that it seems to allow communication at faster
than light speed, thereby apparently violating another of our most cherished
theories, relativity. Now, however, an American physicist is claiming the effect
is an illusion.
“Experiments which seem to be confirming the effect are in fact confirming
something else,” says Frank Tipler of Tulane University in New Orleans. In place
of instantaneous communication, Tipler favours something seemingly much more
bizarre: “The existence of an infinity of other universes in which all possible
histories are…
