Africa-Press – Lesotho. <\/strong><\/span>More than 50 years ago, British scientist Roger Penrose suggested that lowering an object into a black hole\u2019s ergosphere could help it acquire negative energy. This assumption was later elaborated on by another physicist, Yakov Zel\u2019dovich. However, there has so far been no way to test this theory.<\/p>\n

Researchers from the University of Glasgow\u2019s School of Physics and Astronomy have found a way to experimentally verify a 50-year-old theory about an alien civilisation\u2019s possible exploitation of a black hole, according to a study published in Nature Physics.<\/p>\n

In 1969, Roger Penrose proposed a theory that an advanced extra-terrestrial civilisation could generate energy through a black hole by putting an object in its ergosphere, the outer layer of a black hole\u2019s event horizon.<\/p>\n

In this position, the object would have to move faster than the speed of light in order to remain still, while acquiring a negative energy at the same time.<\/p>\n

Shortly after this, Soviet physicist Yakov Zel\u2019dovich said that this theory could be tested using \u201ctwisted\u201d light waves. However, Zel\u2019dovich\u2019s idea has remained just a theory since 1971 due to the technological challenges that his experiment posed.<\/p>\n

Now, researchers from the University of Glasgow\u2019s School of Physics and Astronomy have suggested that twisting \u201cacoustic waves\u201d instead of light can be used in a lab setting to prove the theory.<\/p>\n

The researchers constructed a special system using a \u201csmall ring of speakers\u201d that helped to create a twist in acoustic waves similar to what was proposed by the Soviet scientist.<\/p>\n

\u201cWhat we heard during our experiment was extraordinary.<\/p>\n

What\u2019s happening is that the frequency of the sound waves is being doppler-shifted to zero as the spin speed increases\u201d, said Marion Cromb, the paper\u2019s lead author, as quoted by Phys.<\/p>\n

org. \u201cWhen the sound starts back up again, it\u2019s because the waves have been shifted from a positive frequency to a negative frequency. Those negative-frequency waves are capable of taking some of the energy from the spinning foam disc, becoming louder in the process\u2014just as Zel\u2019dovich proposed in 1971\u201d.<\/p>\n

According to the scientists, they were \u201cthrilled\u201d to be able to verify a half-century-old theory about the generation of energy through a black hole in their lab in Scotland, which they said also opens up a lot of new opportunities for \u201cscientific exploration\u201d.<\/p>\n
