Scientists from college of Glaslow have experimentally verified the theory of how a advanced alien civilization you can use ours black holes To generate Energy.
This postulate was born in 1969 and was suggested by the British physicist Roger Penrose, who affirmed that, when lowering an object to the ergosfera (outer horizon layer) of black holes, it would have to move at the speed of light to stay still.
The theory is that the object, while falling, acquires energy negative. That is, it is subject to very special space-time conditions where, to put it very simply, it is possible “borrow” energy of empty space.
If the object splits in two, with one half falling into the black hole and the other recovered, the recoil would cause some of this negative energy to be lost and the recovered half would gain energy from the rotation of the black hole. This milestone could only be accomplished by a civilization with much more advanced technology than ours.
Years later, the physicist Yakov Zel’dovich He tested the theory with simpler elements. In 1971, he suggested that twisted light waves hitting the surface of a rotating metal cylinder at a certain speed would end up reflecting off additional energy drawn from the cylinder’s rotation thanks to a peculiarity of the rotational doppler effect.
For the same reason, scientists from the Faculty of Physics and Astronomy at the University of Glaslow, 50 years later, tested the experiment with twisted sound.
“What we heard during our experiment was extraordinary. What is happening is that the frequency of the sound waves shifts Doppler to zero as the spin speed increases. When the sound starts again, it is because the waves have shifted from a positive frequency to a negative frequency. Those negative frequency waves are able to take part of the energy from the rotating foam disk, becoming stronger in the process, as proposed by Zel’dovich in 1971.”, Marion Cromb, a doctoral student at the university’s Faculty of Physics and Astronomy, mentions.
Professor Daniele Faccio, also from the Faculty of Physics and Astronomy at the University of Glasgow, is co-author of the article. Professor Faccio added: “We are delighted to have been able to experimentally verify some extremely strange physics half a century after the theory was first proposed. It is strange to think that we have been able to confirm a theory of half a century ago with cosmic origins here in our laboratory in western Scotland, but we believe that it will open up many new avenues of scientific exploration. We are eager to see how we can investigate the effect on different sources, such as electromagnetic waves in the near future. “
The research team article, titled ‘Amplification of waves of a rotating body’, was published in Nature Physics.
