Traversable wormholes are possible under certain gravity conditions

If you want to come back from a trip through a wormhole, you'll need some weird gravity.

Interested in scooting through a wormhole, the ultimate cheat-code through space and time? Perhaps you'd like to hop from star system to star system across the universe without breaking a sweat? But first, you'd better make sure your wormhole is traversable.

"Any traveler trying to cross a wormhole that does not satisfy this will be crushed inside as the tunnel collapses," João Rosa, a physicist at Aveiro University in Portugal, told Live Science.

Rosa is attempting to virtually "build" a stable, traversable wormhole, one that can be safely crossed without the theoretical passageway collapsing or trapping its occupant. And he has recently found that it is indeed possible, but only if we tweak our understanding of gravity.

The problem of traversability
Wormholes are deceptively easy to build — on paper. You start with a theory of gravity. In Einstein's theory of general relativity, gravity defines the relationship between matter and energy, and space and time. The trick to building a wormhole is to find a configuration of matter and energy that allows you to form a tunnel — usually called a "throat" in wormhole research — bridging two distant points in space.
