3/29

1. Is it possible to travel through time?

2. Is it possible to achieve speed faster than light ?

3. Is it possible to travel millions of light year away

in this real world ?

The big and most interesting question are


4/29

1. These are not possible.

2. These are possible only in fictions, movies, novels etc.

3. It is impossible to achieve speed faster than light.

4. It is impossible to travel millions of light year away.

The one answer is, no, it is impossible . . . . . .

Application of wormholes


12/29

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.

14/29

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


15/29


16/29

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.

22/29

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


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
