The
Einstein-
Podolsky-
Rosen Bridge is a
tunnel connecting
two universes. The idea was developed by physicists
Albert Einstein and
Nathan Rosen. They came up with the notion that if an
object had strong enough
gravity, it could
literally rip space, creating a
tear that would
link parallel universes. The only known
object in the
universe with that kind of
force is a
black hole. Anyone who could enter the black hole would find an opening or
wormhole that would take them to another universe. That
wormhole is the
Einstein-
Podolsky-
Rosen Bridge.
The problem with the Bridge is that the same force that warps space would tear apart anything that tried to enter the black hole. Until recently, it was believed that no one could do it. But in 1963, mathematician Roy Kerr came up with a way that someone could approach the black hole to enter the wormhole.
