Nothing can survive a black hole when its events have crossed its event horizon, but mathematical analysis over the past few decades has shown that there is a way to extract energy from a rotating black hole.
Now Researchers have now published a new work introducing an innovative way to increase energy from a black hole, publishing their findings in Physical Review D. Mathematically speaking, if a black hole were to rotate, it would have an edge. This is an area outside its event horizon (which can be protected from the pull of a black hole where you need to move faster than the speed of light) where it is theoretically possible to steal some energy from the black hole.
Researchers Have Found a New Way to Turn a Black Hole into a Power Station
Stephen Hawking worked in such a way that quantum mechanics could remove energy from black holes. Nobel physicist Roger Penrose has a more mechanical method that requires the following specific orbits. The new work focuses on magnetic fields.
The magnetic fields of complex objects often break down and rejoin the line of magnetic fields. It has seen with the spectacular manifestations of energy, for example, the sun. Researchers believe that this could also be the case with black holes. Right magnetic interaction can accelerate the particle away from the black hole, removing some of its energy.
Luca Comisso from Columbia University said in a statement, “Black holes are usually surrounded by a hot ‘soup’ of plasma particles that carry a magnetic field.” “Our theory shows that when magnetic field lines are disconnected and reconnected, in the right way, they can accelerate plasma particles into negative energy and absorb large amounts of black hole energy.”
The scientific reason why this is interesting is that by getting energy from a black hole you are gaining a lot more energy than the energy supplied. The team estimates that the efficiency of the process could be up to 150 percent, which is unacceptable in the world. Therefore, an advanced alien civilization could decide to use a black hole as an incredible energy center if it knew. The scientific reason for this excitement is that without the help of intelligent aliens this process could have already occurred in nature. There are a number of phenomena surrounding black holes, which not fully understood, such as the flames of black holes that can detect from Earth, so the magnetic reconnection in the ergosphere may help explain what we see.
Co-author Felipe Asenjo from Universidad Adolfo Ibanez said in Chile, “Our increased knowledge of the magnetic reconnection that occurs around a black hole can be important for our current and future telescopic observations of the black hole, such as the Event Horizon Telescope, to explain it to us.” Perhaps in the future, mining from black holes could be the answer to our electricity needs.
Comisso said, “Thousands or millions of years from now, humanity may be able to survive in the vicinity of a black hole without harnessing energy from them.” “It’s basically a technical problem. If we look at physics, there’s nothing to prevent it.”
