Engineers have proposed the first model for a physically feasible Warp Drive.

The idea of ​​warp propulsion takes us across large areas faster than the speed of light has long fascinated scientists and sci-fi fans. Even if we are still a long way from jumping over the universal speed limit, it doesn’t mean that we will never ride the twisted waves of space.

Now a group of physicists has put together the first proposal for a physical warp drive based on a concept invented in the 90s, and they say it shouldn’t break the laws of physics.

Theoretically, the warp would bend and change the shape of time and space to exaggerate the difference in time and distance, which in some situations might see a traveler moving across distances faster than the speed of light.

One of those situations was identified more than a quarter of a century ago by Mexican theoretical physicist Miguel Alcubierre. His proposed idea in 1

994 was a spa.cecraft powered by something called ‘Alcubierre drive’ can travel faster than light. The problem is, it takes a lot of negative energy in one place, something that cannot be done according to the existing physics.

But a new study offers a temporary solution. According to researchers from the independent research group Applied Physics based in New York, it is possible to drop the fiction of negative energy and still cause warping, although things may be slightly slower than we would like.

“We go in a different direction from NASA and others, and our research has shown that there are actually other classes of warp drives in general relativity,” said Alexey Bobrick, an astrophysicist at Lund University in Science and Technology. Said Sweden.

“In particular, we have devised a new class of warp drive solutions that do not require negative energy and become physical.”

Why is negative energy such a big deal? Negative energy demands create some common relativity problems of traveling faster than light by allowing space to expand and contract faster than light while keeping everything within variability within limits. Universal speed

Unfortunately, it introduces more of its own problems.Essentially, the negative energy we need exists only in fluctuations at the quantum level. Until we find a way to scoop a mass the size of the Sun, this kind of drive is not feasible.

The new research works – according to the report, negative energy is not needed. But there will be a very powerful gravitational field. Gravity does the heavy lifting of space bending times so that the elapsed time inside and outside the warp differs significantly.

You can’t even book a ticket – the amount of mass required to create a noticeable gravitational effect on space time will be at least the size of a planet, and there are still many questions to be answered.

“If we compress the entire Earth’s mass into a 10-meter shell, the correction of the time within it is very low, only about an hour more this year,” Bobrick said. New scientist.

Another interesting finding from research into the shape of warp drives: wider and taller ships consume less power than long and thinner ships. Think of a plate thrown in front of the wall first, and you will have an idea of ​​the optimal bent drive shape.

Even though the reality of travel to distant stars and planets remains a long way to go. But the new study is the latest addition to a growing body of research suggesting that the principle of warp drive is scientifically rational.

The researchers agree that they are not yet sure how to incorporate the technology they describe in the paper. But at least the numbers are increasing by now. They are confident that in the future the perverse drive will become a reality.

“While we are still unable to break the speed of light. But we don’t need to become interstellar, ”said Gianni Martire, one of the scientists at the Applied Physics group behind the new study. “Our warp drive research has the potential to bring us all together.”

The research is published in Classical and quantum gravity.
