ER = EPR, however, suggests that the key to their connection can be found in
the spacetime tunnels known as wormholes.
But much work in recent years suggests that such
spacetime tunnels might link two black holes, in which case travel through them becomes thinkable, even if not physically, emotionally or economically feasible.

Wormholes are shortcuts through
spacetime, the rough equivalent of crossing a mountain via
tunnel rather than climbing over it.
Wormholes,
tunnels through the fabric of
spacetime that connect widely separated locations, are predicted by Einstein's general theory of relativity.
