Not so long ago, there were rumors in the media that they had finally created a warp engine in NASA. Official representatives of the organization had to refrain from throwing in, explaining that in fact tests were conducted on a completely different device, EmDrive. But the interest in a fantastic device that distorts space does not subside. Futurists believe: somewhere in secret laboratories a warp engine is being developed. NASA tests, however, did not, because in practice nothing similar was created. At least, official sources do not provide any information about this. It remains to be content with theoretical information.
Some scientists believe that spacecraft can fly, with speed at times greater than the speed of light. In practice, the research did not bring the engine closer to its actual incarnation. But, one way or another, such statements are pleasing to the listeners of fantasy and young romantics who dream of plowing outer space.
Texas scientists Gerald Cleaver and Richard Obawi, who published their work on the Internet, consider the creation of a hyper-speed ship possible, since it does not contradict Einstein's theories of relativity and strings.
The latter is confirmed in some recent discoveries (for example, the discovery of the variability of world constants or the presence of additional spatial dimensions).
In their studies, the Americans made a start from the work of the Mexican physicist, Miguel Alcubierre, who wrote it back in 1994 and called the "Space Deformation Engine."
How does it work
The principle of its operation is as follows. The warp engine forms a closed bubble around the spaceship, separating part of the space-time. The drive causes it to expand behind, and in front - to contract. Due to this, the bubble acquires the ability to move forward at a speed exceeding the speed of light.
It is stated that the condition under which the speed of light can not be exceeded is fulfilled. After all, the beam next to the ship will fly forward along with it.
But a bubble with a part of space-time will arrive on some star much faster than another ship, as if it started simultaneously with the one on which the warp engine is mounted.
According to natural laws it turns out that it will remain immobile during the whole journey, and its kinetic energy will remain the same as before the start.
Along with the development of the universe
Is it possible in reality to allow the expansion of space-time? Physicists refer to the beginning of the development of the universe, when not only the matter expanded, but also the spatial tissue.
Cleaver claims that behind the ship they seem to recreate the processes of the young universe. In order for a spaceship to find itself in such a bubble, it is necessary to exotic negative energy (the same as for a time machine). And the researchers even know how to get it.
"The Casimir effect"
They believe that we must rely on the "Casimir effect." It is claimed that between two bodies, which are located at a close distance in a vacuum, there is an attraction. It is formed as a result of the difference of virtual photons created in a vacuum. Between their bodies there will be much less than in the rest of the vacuum. Scientists believe that this effect can help travelers in space. After all, translating into physical concepts, the same negative energy arises between the bodies, which is required.
The source is in "dark" energy
In addition, it is believed that the negative is also in the so-called "dark" energy, which today causes the expansion of the universe. Scientists are sure that the warp engine will become a reality just when they understand this energy.
But how to make space expand beyond the formed bubble? It is suggested to use additional dimensions of space, the existence of which follows from string theory.
For easier understanding, you can mentally draw a line through space. We represent that it consists of points. But if each of them is greatly increased, they will turn into rings, which are the manifestation of these measurements.
Scientists believe that virtual photons having a wavelength that is capable of resonating with a circumference are born there. The rings here play the same role as the plate bodies, the concept of which is present in the theory of the "Casimir effect."
And how will everything be put into practice?
It is assumed that by changing the size of additional dimensions, it is possible to calculate a part of the space-time in the bubble. The logic here is simple: with the expansion of additional dimensions, our space-time is compressed and vice versa.
To create a warp engine was a success, an energy of the order of 10 45 joules is needed. For comparison: so much of it is contained in the whole mass of Jupiter, if counted according to the well-known formula of Einstein. Previously it was believed that an even colossal amount of energy is needed, comparable to the mass of the entire universe.
Cleaver also theoretically calculated what a warp engine speed should have. It exceeds the speed of light by 10 32 times. The scientist immediately adds that the magnitude is unattainable neither with the already available, nor with all that can only be imagined by technology.
Practical implementation of the expected from here, in general, and not worth it. After all, everyone knows that Americans fly into space on Russian engines. By the way, does it follow that they flew to the moon on a Soviet engine? Well, proceeding from such data, it seems that if there is ever created a warp engine, at least Russia will take an active part in its development.
