Black holes will become sources of energy: scientists are looking for a way to extract it

The energy of black holes can be used for business

The scientists from Columbia University are conducting a research proving that black holes can be a source of energy. It can be removed by reconnecting the magnetic field lines. Einstein turned out to be right, the black holes impose huge reserves of energy and it is available for use. The physicists devoted the last 50 years to finding ways to extract it. A physicist Roger Penrouse suggested that the energy of a black hole could be extracted by decaying particles.

And Stephen Hawking proposed a theory according to which the black holes release energy through quantum mechanical radiation. Physicists Roger Blandford and Roman Znaek proposed electromagnetic torque as the primary energy extraction agent.

A new study by Columbia University researchers helped them to find another new way to extract energy from black holes. It looks like breaking and connecting magnetic field lines near the event horizon, from where not even light can escape due to the gravitational pull of the black hole.

A researcher Luca Cosmiso says the putative theory shows how magnetic field lines can connect and disconnect, propelling plasma particles to negative energies while extracting a huge amount of black hole energy.

Over the time, a method will be developed to collect this energy and it can become a source for various needs of an advanced civilization. This theory is built on the premise that magnetic fields accelerate plasma particles in two different directions.

One stream of motion is against the rotation of the black hole, and the other is in the same direction with it. This process can release energy. In theory, it can occur in an area called the ergosphere. At this point, the space-time continuum spins so fast that every object spins in the same direction as the black hole.
