Speed of light, which is 300,000 km / s, is indicated by the theory of relativity developed by Albert Einstein in the universe as an absolute threshold beyond which it can not pass.
It is apartamente de vanzare bucuresti the ultimate speed, which is certified by Einstein and other scientists, but for science fiction authors and movie genre, this constant becomes more malleable. They are used often means making more of an idea of the possibility of exceeding the speed of light interstellar travel that does not last forever.
One is the "engine Alcubierre" speculative solution, but valid, "extracted" directly from Einstein's theory of relativity. It is a mathematical model of space-time, presenting possibilities reminiscent of fictional "warp drive" from Star Trek, which could travel faster than the speed of light, although not local purposes.
In 1994, the Mexican apartamente de vanzare bucuresti physicist Miguel Acubierre proposed a method of stretching space in a wave which, in theory, would make the space before a spacecraft to contract and expand at the back. The ship would be able to travel on such a wave in a region known as bubble warp (deformation) of flat space. Since the ship is not moving in this bubble, but carried forward with the entire region, conventional relativistic effects such as time dilation, no longer apply.
However, it is apartamente de vanzare bucuresti not yet known methods to create such a "bubble" and "Alcubierre engine" can not be tested, so a trip to Proxima Centauri, the nearest star system, would take all 4.5 years, if the ship were would move at lightning speed. Of all mathematical models generated by relativistic physics, it appears that a apartamente de vanzare bucuresti ship can never reach the speed of light, will be always a fraction behind her, so no it could not be overcome it.
Relativity shows that time slows down more and more to anyone who would move close to the speed of light. Exceeding the speed of light issue, though, is unhealthy speculative. All solutions that would fit the rigors of general relativity involve manipulation of matter and energy, and one of the problems occur when you call the "Alcubierre engine" is that you need negative energy density. And this is an extremely difficult since it is not clear whether the so-called "exotic energy" exists or may exist in our universe.
Another theoretical solution, according to Einstein's relativity, it would be "Casimir effect", which, among others, show that emptiness cosmos appears to be crossed by a vacuum energy with some strange properties. Vacuum energy and the exotic But are things really different.
Vacuum energy is negative pressure, while exotic energy require negative energy density, which is not known if any, remaining in the purely speculative. Basically, to make a "warp bubble"-sized spacecraft would be necessary amount of energy throughout the observable universe. So Alcubierre engine remains an interesting speculation relativistic mathematics in mind. Then that would be a sure way to avoid boundary imposed by the speed of light?
Some would respond that "wormholes" offers the most reasonable solution. A "wormhole" has two ends, each with a level close gravitational "black holes" when a remote examined. A apartamente de vanzare bucuresti "wormhole "can act as a permanent connection between two points in space and time travel between the two points would be equal to that required strabaterii access tunnel between the mouths of the wormhole. They are a constant presence in the series "Deep Space Nine" or "Star Trek: The Next Generation". So just have absolutely no idea how to create one.
There is speculation that such wormholes are formed constantly, even in our neighborhood, at the microscopic level (there are so-called Einstein-Rosen bridges) but ephemeral life, lasting nano-seconds. One can not even imagine how to gravitational collapse do not even like to be crossed before the first photon. Another theoretical possibility of "adjusting" the speed of light as quantum teleportation, but, like other concepts, the first difficulty is wonderful to practice.
