The researchers created the first laboratory analog of the ‘black hole bomb, a theoretical concept developed by physicists In the 1970s.
If there is one thing black holes are known for, it is their insatiable and essential severity. Tips enter a black hole. You are not really going to get out.
From beyond the horizon of the event, it is, as far as we know, it is true. But space around a black hole, you may be able to get something. Like Roger Penrose proposed in 1971The powerful rotation energy of a rotating black hole could be used to amplify the energy of neighboring particles.
Then, the physicist Yakov Zel’dovich understood that you did not need a black hole to see this phenomenon in action. A symmetrical axial body running in a resonance chamber, He thoughtcould produce the same energy transfer and amplification, although a much smaller scale.
Subsequent work By other physicists have noted that, if you enclose the entire device in a mirror, a positive feedback loop is generated, amplifying energy until it explodes from the system.
This concept was appointed Black Hole Bomb, and a team of physicists led by Marion Cromb of the University of Southampton in the United Kingdom now claims to have given it life. An article describing their experience has been Downloaded on Preprint Server Arxiv.
This is not the case, just to make your mind comfortable, pose a danger. It consists of a rotary aluminum cylinder, placed inside the layers of coils which generate magnetic fields which revolve around it, at controllable speeds.
First of all, we have to talk a bit about ergosphere of a black hole – space outside the horizon of the event. We know that Gravity distorts space-time. The gravitational field of a black hole is so strong that it does not just distort space-time, it drags it with its rotation. This is called brewing.
When the particles cross the space-time that affected gravitation, they somehow embark on their own speed. But if this space -time moves and the particles move in the same direction as this movement, they seem to move more quickly towards anyone outside this moving space – a bit like walking along a traveler at an airport.
When the particle emerges from moving space-time, it has more momentum.

We cannot experimentally reproduce this gravitational effect; What the team experiences is to simulate it, using magnetic fields as an indirect particle indicator, the coils around the system acting as a reflector to produce the feedback loop.
When they have executed the experience, they found that when the cylinder turns faster than, and in the same direction as the magnetic field, the magnetic field is amplified, compared to when there is no cylinder. However, when the cylinder turns slower than the magnetic field, the magnetic field is attenuated.
It is a really interesting result, because it demonstrates a very clear amplification effect, based on theories described decades ago.
“The system meets the experimental conditions speculated by Zel’Dovich for the observation of the spontaneous generation and also the conditions described by Press et al. For the black hole bombs”, ” Researchers write in their article.
“The experiences presented here are a direct realization of the rotary absorber amplifier offered for the first time by Zel’Dovich in 1971 and developed later by Press and Teukolsky in the concept of bomb with black hole.”
Because we cannot probe black holes directly, Analogues like this are a great way to understand their properties. The determination of all potential practical applications will require much more development and tests.
For the moment, however, experience could represent an important step towards a better understanding of physics The most extreme gravitational in the universe.
