Application of wormholes

Faster than light travel
The impossibility of faster-than-light relative speed only applies
locally.
Wormholes allow superluminal travel by ensuring that the speed of
light is not exceeded locally at any time.
While traveling through a wormhole, subluminal speeds are used.
If two points are connected by a wormhole, the time taken to
traverse it would be less than the time it would take a light beam to
make the journey if it took a path through the space outside thewormhole.

Inter-universe travel
A particle returning from the future does not return to its universe
of origination but to a parallel universe.
This suggests that a wormhole time machine with an exceedingly
short time jump is a theoretical bridge between contemporaneous
parallel universes

Time travel
This would be accomplished by accelerating one end of the
wormhole to a high velocity relative to the other, and then sometime
later bringing it back
Relativistic time dilation would result in the accelerated wormhole
mouth aging less than the stationary one as seen by an external
observer.
Time connects differently through the wormhole than outside it, so
that synchronized clocks at each mouth will remain synchronized to
someone traveling through the wormhole itself, no matter how themouths move around.
Anything which entered the accelerated wormhole mouth would
exit the stationary one at a point in time prior to its entry.

History of discovery of wormhole
The first type of wormhole solution discovered was the
Schwarzschild wormhole which would be present in theSchwarzschild metricdescribing an eternal black hole, but it was
found that this type of wormhole would collapse too quickly for
anything to cross from one end to the other.
The American theoretical physicistJohn Archibald Wheelercoined
the term wormhole in 1957.
In 1921, the German mathematician Hermann Weylalready had
proposed the wormhole theory, in connection with mass analysis ofelectromagnetic fieldenergy.

In 1935, The EinsteinRosen bridge was discovered by Albert
Einsteinand his colleague Nathan Rosen.
In 1962 John A. Wheelerand Robert W. Fullerpublished a papershowing that this type of wormhole is unstable if it connects two
parts of the same universe,.
The possibility of traversable wormholes in general relativity was
first demonstrated by Kip Thorneand his graduate student Mike
Morrisin a 1988 paper.
Later, other types of traversable wormholes were discovered as
allowable solutions to the equations of general relativity, including a
variety analyzed in a 1989 paper by Matt Visser, in which a path
through the wormhole can be made where the traversing path does
not pass through a region of exotic matter.

Schwarzschild wormholes
An artist's impression of a wormhole from an observer's
perspective, crossing the event horizonof a Schwarzschild wormhole
which bridges two different universes.
The observer originates from the right, and another universe
becomes visible in the center of the wormholes shadow once the
horizon is crossed, the observer seeing light that has fallen into theblack holeinterior region from the other universe.
however, this other universe is unreachable in the case of a
Schwarzschild wormhole, as the bridge always collapses before theobserver has time to cross it, and everything that has fallen through
the event horizon of either universe is inevitably crushed in the
singularity.

Lorentzian wormhole
Lorentzian traversable wormholes would allow travel in both
directions from one part of the universe to another part of that same
universe very quickly or would allow travel from one universe to
another.
For this reason, the type of traversable wormhole they proposed,
held open by a spherical shell of exotic matter.

Stablization of wormhole
The predicted Einstein-Rosen wormholes would be useless for
travel because they collapse quickly.
But more recent research found that a wormhole containing
"exotic" matter could stay open and unchanging for longer periods
of time.Exotic matter,
a wormhole contained sufficient exotic matter, whether naturally
occurring or artificially added, it could theoretically be used as a
method of sending information or travelers through
8/10/2019 Wormholes power point presentation
24/29
British cosmologist Stephen Hawkinghas argued that such use is
not possible.
Although adding exotic matter to a wormhole might stabilize it to
the point that human passengers could travel safely through it.
But..
Today's technology is insufficient to enlarge or stabilize wormholes,
even if they could be found.

Metrics of wormhole
Theories of wormhole metrics describe the space time geometry of a
wormhole and serve as theoretical models for time travel.
An example of a (traversable) wormhole metric is
One type of non-traversable wormhole metric is the Schwarzschild
solution
