Employee RUDN and his Brazilian colleagues have questioned the concept of using stable wormholes as portals to different points of space-time. The results of their research were published in Physical Review D. the Wormhole is a pretty hackneyed cliché in science fiction. A wormhole, or "wormhole", it's kind of a tunnel connecting distant points in space or even two universes, through the curvature of space-time.
Theoretically, a wormhole could spend from one point in space to another, bypassing the actual overcoming of the distance between them. Roman Konoplya, people's friendship University physicist, estimated the possibility of such interstellar travel.
the"Our hope for the existence of these exotic objects is based on the fact that the Einstein equations allow wormholes to be their decision. However, to through the wormhole could pass and she should not imploded due to the gravitational effect, the power pushing in a narrow space of the wormhole needs to be extremely high," says Roman Hemp.
Usually, theoretical physicists offer two options for repulsive forces: concentration of dark energy or vacuum fluctuations of quantum fields in a narrow place. Both decisions are quite unusual and require a degree of imagination and optimism for further development.
In 2011, Greek and German scientists found that a pushing force can be explained without introducing new fields or unusual types of matter. According to their calculations, the repulsion is possible to get as a result of quantum corrections of Einstein's theory motivated by string theory in the approximation of low energies (the so-called Einstein-Gauss-bonnet with dilaton). If the wormhole will be stable to small temporal and spatial fluctuations, it will be a promising theoretical model based on the fundamental string theory.
"Some preliminary studies of foreign colleagues seem to indicate the possibility of such stability. However, we confirmed that the wormhole is in accordance with Einstein's theory with quantum amendments is critically unstable. Obviously, such unstable system can not exist in nature, because any reaction with the environment will lead to its destruction. Unfortunately, the math shows that we have still no theoretically consistent model of wormholes without exotic assumptions," says Hemp.
