• An observer passing through a wormhole could
traverse it in less time that it would take to travel
through normal space-time outside the wormhole.
• Theoretically, wormholes
can be used to travel to
the future and the past.
No observational evidence
for wormholes currently
exists, but mathematical
wormholes have long been
known to be valid
theoretical solutions to
Einstein’s field equations of
Are safe travels
Tidal gravitational forces at the throat of a Schwarzschild
wormhole are of the same magnitude as at a horizon of a
Schwarzschild black hole.
A Schwarzschild wormhole is dynamic, not static—it can
contract to zero throat circumference to maximum throat
circumference in a very rapid rate.
A Schwarzschild wormhole has an unstable past horizon
which can hasten the opening and closing of its throat.
1.Symmetric and static
2.Must obey Einstein’s field equations
3.Must have a throat that connects two asymptotically flat
regions of space time
4.Must not have a horizon
5.Must have bearable tidal forces
6.Must be traversable in a finite amount of time
7.Must be physically reasonable
8.Should be possibly assembled
