Superluminal, future us how to fly — from theoretical physics of angles "Star Trek"

A cosmic artist's superluminal flight of the magnificent landscape.

A worm hole model. If you are from the universe of A flight to B, the traditional flight path is long, but use the wormhole you can quickly reach. Stephen Hawking wheelchair pointed out that the theory of innovation may make space travel speeds access to revolutionary progress, then to develop alien colony. "Science fiction in the moment you arrive at the destination," Stephen Hawking said, "Unfortunately, this would run counter to the scientific principles. Scientific principle that any thing is not to exceed the speed of light. ”

In 1905, Einstein published "on the electrodynamics of moving bodies.

This greatly stimulated the imagination of science fiction, but also manufacture a relentless nightmare — anything relative motion speed must not exceed the speed of light. However, superluminal travel remains the human universe tour to the most beautiful dream. Sci-fi film "Star Trek" has been taking the lead in beyond Einstein.

1 warp flight

Instantly reach their destinations

In order to achieve the hyperspace travel, all sorts of fancy stunts in "Star Trek" turns into battle — warp flight (WarpDrive), wormhole, three-dimensional transmitter hallucination deck, holographic and so on.

Audience, warp flight is a xuanji; but on the "enterprise", this is it's basic skills.

The need for the plot of the story, the protagonist must be light-years of the Galactic magnitude, quickly reached from another planet Earth.

Enterprise's warp flight, as an ordinary space distance far from places of departure and destination, in high dimensional spaces overlap, thus to achieve faster than light travel.

At the Shanghai Jiao Tong University Professor Jiangxiaoyuan and his doctors Mu Yun autumn cooperation of papers, they point out in "Star Trek" specialized technical manuals and even can see producer for "enterprise" warp flight preparation of the basic formula. With the introduction of new television series, the upgrading of business numbers, this formula is constantly adding new parameters to fix and perfect, though it never directly on the TV screen.

Popular science writer Zhang Xu said, from Plato to Newton to Einstein's theory of physics concepts, although it has been turned upside down, "but supporting physics of causality midstream".

For example, how many times must first play cannon to hit the enemy, it is not possible to hit the enemy artillery shell first then play Cannon relativity does not allow the superluminal, "because the superluminal undermine causality, physical logical disappeared. ”

"Star Trek" clever use of warp flight, did not undermine causality, and enables faster than light.

On the surface, it is in a very short time to reach the speed of light that reaches the place, in fact, the spacecraft in negative energy density of singular of support, change space physical structure, create shortcut to shorten the space distance so that the spacecraft in time to defeat the speed of light "on".

Although, the Star Trek "warp flight is a fantasy, but scientists still lit.

Recently, Baylor University Physics Professor g Sullivan (GeraldCleaver) and postdoctoral fellow Austrian Bo plug (RichardObousy), has developed an aggressive plan to attempt to let the "Star Trek" in the show's warp flight into practical step, of course, they still have little chance of success.

2 worm hole

In the universe "across"

United States theoretical physicist Thorn (KipThorn) famous "worm hole" theory and warp flight.

"Worm hole" nature have long been discus

sed. Jiangxiaoyuan and Mu Yun autumn pointed out that the 1916, Einstein's general theory of relativity has been published for a few months, Schild in Einstein's field equations of gravitation found a solution — famous schwarschild. 1935, Einstein and its academic Assistant Rosen in a paper, to connect the universe between two distant region of hypothetical channel called "bridges" — then this is referred to as "the Einstein-Rosen bridge", "worm hole."

Popular science writer Zhang Xu, for example, suppose that we live in a normal universe is an Apple, humanity is living in a cosmic surface of worms.

They only have the ability to climb up to the surface, if one day they realize the description of the fruit is a surface, and have a bite in fruit surface ability, worms in Apple's "bite" a hole. So, from one place to another in the distance is also a short distance than fruit. Our universe is not necessarily flat, simple, there may exist more high-dimensional space. Earth's distance from Vega is 26.5 light-years, but through a wormhole connection they, perhaps, only 1 km.

However, to the wormhole to make superluminal travel problems, and that is how to guarantee the opening hours of the wormhole.

Thorn's ultimate idea is to have a "negative energy density" of singular thing as keep wormhole remain open material condition whereby the wormhole will be transformed into violating causality time machine for interstellar voyage. "In addition, the use of two black holes as a wormhole has also become a hypothesis is proposed. " Chinese Academy of Sciences Institute of theoretical physics researcher limiao pointed out.

P > 3 light wave transmission

Go back to the future

The Star Trek 11, young unruly Kou Ke is broken down into "quantum" exile to the snow, the monster attacks, accidents to see old history back.

Kou grams of this adventure tour is the "enterprise" and "lig

ht wave transmission system". This high-tech transfer devices is time machine, a member of the enterprise, arrives at any place. This device is fictional. Available in order to achieve the time travel, time machine was designed. And its related theory is attributed to such a concept: and constitute the three dimensions of space, time is also a variable dimension.

Until 1905, physicists believe that time as a branch of the future of an arrow, shot, I will not turn on.

But if you want to turn back the clock, you will need superluminal. However, the speed of light is an impassable limit. Limiao pointed out that neither the classical mechanics or quantum mechanics, the speed is not exceeded. However, there are special circumstances, that is in the areas of quantum entanglement. Quantum physics is of the view that a pair of micro-particle interaction may have a particular contact. On one of the particle effects, may at the same time on another at the same time, even if they both have very far apart. Obviously, this also effects beyond the speed of light.

At the same time, the scientific community, numerous hypotheses in solving the problem of superluminal so as time machine's superluminal travel found.

1937, Netherlands physicist J.vanStockum from Einstein's field equations in a solution that has a fast rotation and an infinite cylinder gravity field. This field will violate causality, it allowed the connection of two time closed class time curve. 1949, Austria mathematician Godel (KurtGodel) found a solution to Einstein's field equations, describes a spin but neither expanding nor contraction of the whole universe. In theory, it allow time travel. Of course, the we observed in the universe is expanding, but has not emerged. Limiao pointed out that, although now there have been some of the solutions of Einstein's field equations, but at the moment for time machine's hypothesis in mostly on the closed class curve.

■ Rumored

Reality version of "Star Trek"

Science and science fiction always bidirectional.

Appear in the science fiction movie of some high-tech is gradually become our reality. Here is the "Star Trek" brought us some of the relevance of technology.

● Military laser gun

"Man-portable non-lethal laser rifle" is a United States Air Force research laboratory directed energy headquarters of successful development.

It uses a with two different wavelength of the laser system can make the enemy temporarily blind. It and the "Star Trek" in the light gun rifle rather similar.

● Transparent aluminum armor

Transparent aluminum armor (aluminum nitrogen oxides ALON) has been United States Army as a lightweight, high strength material for testing.

ALON is a type of ceramic material, with very high compressive strength and durability, than the traditional glass fiber reinforced plastic materials performance better. "Star Trek" in the transparent aluminum materials and ALON has similarities.

• Cosmos Galaxy-access currency

"Star Trek" astronaut they need money to buy goods and enjoy a variety of services.

Astronaut in future real space will be used in the life of the "Cosmos Galaxy-access currency" (QUID), which is dedicated to the future scientists star tourist use of space. Allegedly, 1QUID convertible 6.25 pounds.

● Language translator

"Star Trek" in the "corporate", members often come into contact with other intelligent life in the Galaxy, and when it comes to the language of different planet, they will use a "universal translator" will extraterrestrial languages translated.

In reality, the US military in Iraq using Phraselator translator also to language translation.
