The idea of a main disk that transports us through large spaces of space faster than the speed of light has long fascinated scientists and science fiction fans. Although we are still very far from jumping over any universal speed limits, this does not mean that we will never ride the waves of distorted space-time.
Now a group of physicists has prepared the first proposal for physical distortion, based on a concept created in the 1990s. And they say he must not violate any of the laws of physics.
Theoretically, deformation discs bend and change the shape of space-time to exaggerate the differences in time and distance that in some circumstances can see passengers travel distances faster than the speed of light.
One of these circumstances was outlined more than a quarter of a century ago by the Mexican theoretical physicist Miguel Alcubier. His idea, proposed in 1
But the new study has a workaround. According to researchers from the independent research group “Applied Physics” based in New York, it is possible to abandon the fiction of negative energy and still make a deformation, albeit one that may be a little slower than we would like.
“We went in a different direction from NASA and others, and our research showed that there are actually several other classes of basic drives in general relativity,” said astrophysicist Alexei Bobrik of Lund University in Sweden.
“In particular, we have formulated new classes of solutions for basic drives that do not require negative energy and thus become physical.”
Why is negative energy such a big deal? The need for negative energy circumvents some of the main problems of relativity traveling faster than light, allowing space to expand and contract faster than light, while maintaining everything in its distortion within the universal speed limits.
Unfortunately, it creates more problems of its own – mainly that the negative energy we would like exists only in fluctuations on a quantum scale. Until we can figure out a way to accumulate a mass of things the size of the Sun, this kind of drive is simply not possible.
The new study works around this – according to the article, no negative energy will be needed, but it would be an extremely powerful gravitational field. Gravity would make it difficult to lift the bending space-time so that the flow of time inside and outside the base machine would be significantly different.
You still won’t be able to book tickets – the amount of mass needed to achieve a noticeable gravitational effect on space-time will be at least the size of the planet, and there are still many questions to answer.
“If we take the mass of the entire planet Earth and compress it to a shell the size of 10 meters, then the correction in the speed of time inside it is still very small, only about an extra hour a year,” Bobrick said. A new scientist.
Another interesting finding from the study relates to the shape of the base: a wider and taller vessel will need less energy than a long and thin one. Think of a slab held upright, thrown first on the wall, and you have an idea of the optimal shape of the base drive.
Although the reality of traveling to distant stars and planets is still far away, the new study is the latest addition to a growing body of research that suggests that the principles of warp propulsion are scientifically sound.
Researchers admit that they are still not sure exactly how to put together the technology they described in their article, but at least more of the numbers are being collected now. They are confident that far in the future, the deformation will become a reality.
“Although we still can’t break the speed of light, we don’t need to become an interstellar species,” said Gianni Martire, one of the scientists in the applied physics group behind the new study. “Our study of the foundation has the potential to unite us all.”
The study was published in Classical and quantum gravity.
