An American researcher claims to have found a way to travel to other star systems: he says it can be done using the energy of black holes.
One of the main problems that currently prevent the realization of such journeys is the fuel, since the existing spacecraft do not have propulsive forces suitable to reach the necessary speed in those distances. However, Professor David Kipping, of Columbia University (New York, USA), has probably solved the obstacle, as he proposes use the force of gravity of black holes to get the energy those ships need. The concept, which he called "Halo Drive" ("Motor halo", in English), was described in an article published on March 11th.
The scientist points out that binary black holes have a large amount of energy, which appears as a result of their rotation. At the same time, they act as "giant mirrors" that indeed can reflect energy they receive, a quality that they believe can be used. In detail, he proposes to equip the carrycot with "high power laser", which would have thrown a beam of photons into black holes, when they reached them, the flow of charged particles would curve around the space object, capturing further energy and returning to the device.
The realization of this concept, he said, would make it possible to reach other star systems without the need to transport fuel. The Universe Today portal specifies, based on scientific estimates, that there may be in the Milky Way 100 million black holes that "could act as a network" for an interstellar journey.
Disadvantages of the project
However, the ambitious project also involves important obstacles; among these, the fact that today there are no spaceships capable of transforming the idea into reality. Furthermore, even if the experts had succeeded in building the right devices, there would be a risk that they would be devoured by the black hole itself.
For the rest, to travel using this energy source it is necessary, first of all, to find the hole that could supply it. "This has a great disadvantage for us, [que consiste] in which first we have to go to one of those black holes"Kipping admitted.
"I tend to think of this as a interstellar highway systemYou have to pay the toll once, to get on the highway, and then you can travel around the galaxy as much as you want without spending more fuel, he said.
The specialist said he will continue to work on the idea and that in a future study he will try to determine how the nearest black hole could be reached, from there to start the real shift. "Interstellar travel is one of the most demanding technical companies that we can conceive ", emphasizes Kipping.
