The Bizarre Nature of Black holes Explained by Brian Greene

A black hole is one of the strangest and most fascinating objects in outer space. It is formed when a star with sufficient mass is dying. The gravity is so strong because matter has been squeezed into a tiny space that not even light can escape from it.

American theoretical physicist, mathematician, and string theorist Brian Greene explains the bizarre nature of black holes. He explains in detail how 2 black holes collided about 1.4 billion light years away from Earth that produced gravitational waves that got picked up by LIGO, the Laser Interferometer Gravitational-wave Observatory.

Brian Greene explains how black holes can be very counter intuitive. A fascinating type which can reach up masses 20 times more than that of our sun are stellar black holes. But their size is nothing compared to some of the enormous supermassive black holes with mass on the order of millions to billions of times the mass of the Sun.

However black holes can be big or small. Some scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain.

Another fascinating fact about black holes according to a new paper in the journal "Annals of Physics" is that the geometry of spacetime around a black hole behaves like a quantum computer, and it can encode photons with quantum messages.

The distorted geometry of spacetime near rotating black holes can create and manipulate quantum information encoded in beams of light that are emitted by, or that pass close to, these black holes.

In a theoretical quantum computer, a quantum computation process consists of photons traveling throughout a setup of mirrors, beam splitters, and prisms that switch the polarization and twisted phase of photons to values that can be mapped onto zeros and ones.

A new suggestion is that the geometry of spacetime near spinning black holes acts in an identical manner to this setup of prisms and mirrors, This means that a spinning black hole writes a quantum code that we may decode in the near future when we come to create quantum computers.

Brian Greene also mentions how there is now a connection between quantum computing and black holes. We may be on the verge of a new technological era, an era that will be dominated by quantum technology. We have legitimate hopes that these quantum computers will help unveil some of the now-hidden mysteries of the universe.
