Humanity dreams that one day it will be able to travel easily in and out of the solar system. The laws of physics unfortunately limit the speed at which we can travel through the universe. There is still hope, however, that Alcubian’s metric, which will allow light to travel faster than light without violating the principle of relativity – a theory that has been explored for many years by Dr. Harold “Sony”, a former NASA researcher.

Harold White worked extensively on the development of a warp engine (running on Alcubier’s metrics).Advanced Propulsion Physics Research Laboratory From NASA in 2020, he co-founded with former astronaut Brian Kelly Unlimited Space Institute (LSI), a non-profit organization whose goal is to “inspire and educate the next generation to travel beyond our solar system and to assist in research and development to enable technology.”

The organization, which enjoys growing support, now has the resources to provide research grants to schools and universities – from $ 100,000 to less than a two-year postdoctoral fellowship. বেশি More than ,000 90,000 per year Several big names in the aerospace sector have already joined the company, including several retired astronauts. Gwynne Shotwell, SpaceX’s chief operating officer, recently joined the institute as an independent adviser.

A growing rational idea

If the financial support of the Institute is an advance comfort today, the concept of engine with distortion remains in the field of science fiction even today. According to the theory of relativity, the speed of light is constant and absolute, and the inert mass of the objects that approach it increases; Therefore, it will take an extreme amount of energy to accelerate.

Alcubier’s metric – named after the Mexican theoretical physicist Miguel Alcubier, who proposed it in 1994 – involves a space-time catastrophe that will shrink on one side and expand on the other. ” Through the purely local expansion of spacetime behind the spacecraft and the reverse contraction in front of it, it is possible to travel faster than the speed of light observed by observers outside the confused region. The physicist wrote in his article on the Warp engine.

Thus, theoretically, an engine based on this model would allow a ship to travel in this warp at superlight speeds and still respect the laws of physics. However, Alcubierre himself concludes that the concept requires an energy concentration that is less than the emptiness of space – that is, a negative mass, an “external” object whose existence remains entirely theoretical.

Although Alquier’s research predicted an immeasurable amount of negative mass (equivalent to the mass of Jupiter!), More than anything humanity could create, in 2011 Dr. White’s revision of his calculations eventually led to a more “reasonable” amount. To do this, he revised the Warp Bubble’s “shell thickness” parameter: a thick warp shell would reduce the pressure on spacetime, allowing a spacecraft to reach speeds of up to 10 times the speed of light using only two metric tons of external material. Warp engines have therefore become more conceivable.

A three-step research program

It remains to find a way to generate negative energy in a vacuum. It’s partly LSI’s Raisin D’Trey, which follows the dream of allowing humanity to travel long distances in reasonable time. For the development of this still unknown physics, LSI has adopted a three-stage research plan, which includes various types of increasingly advanced propulsion: 1) nuclear electric conduction, 2) fusion electric propulsion and 3) warp drive.

Nuclear electric propulsion (NEP) – already widely studied by NASA and other space agencies for future exploration – relies on hall-effect thrusters that ionize inert gases to create charged plasma, which is used to make propulsion. The concept, which is based on well-known physics, has already proved itself through various experiments. White and his colleagues are working on a NEP engine capable of generating 2 to 50 megawatts of power, which will allow rapid transit to the outer solar system.

Other star systems, including Proxima Centauri (Proxima Centauri), on the other hand, will require much more energy to observe, which can only be provided by Fusion Electric Propulsion (FEP). ” Instead of fission and uranium we use a combination of deuterium and tritium or gas which we can fuse in the form of plasma at very high temperatures. White says. Such an engine could deliver 50 to 500 megawatts of power and take us to the Proxima Centauri in a hundred years. To further reduce travel time, we must find a way to link relativity and quantum mechanics, or find a “theory of all things.”

The activities of LSI and its partners (NASA, MIT, Texas A&M University), as well as its grant programs aimed at encouraging research in space exploration, could lead to greater success, which would be achieved faster than expected. ” Establish the ability to send people to all destinations in the solar system – think about it! Having a complete solar system of materials and resources will change the perception of scarcity “, White said Universe Today, Adding that having this capability means that our planet will essentially be in a different position when it comes to energy production and use. Crossing the boundaries of our solar system can therefore be a way to preserve our own planet.
