Weird Quantum ‘Magic’ of Black Holes

 

Quantum Black Hole

 

“Black holes are an incredibly unique and fascinating feature of our universe,” said University of Queensland theoretical physicist, Joshua Foo about their mind-bending ability to have different masses simultaneously. “They’re created when gravity squeezes a vast amount of matter incredibly densely into a tiny space, creating so much gravitational pull that even light cannot escape. It’s a phenomenon that can be triggered by a dying star. But, until now, we haven’t deeply investigated whether black holes display some of the weird and wonderful behaviors of quantum physics.

Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of the matter in the universe was not visible. About 84 percent of the matter in the cosmos is dark matter, much of it located in halos around galaxies. It was dubbed dark matter because it does not emit light, but it is also mysterious: it is not composed of atoms or their usual constituents like electrons and protons.

“The fate of black holes in a quantum theory of gravity is, in my view, the most important problem in theoretical physics,” said Jorge Pullin, the Horace Hearne professor of theoretical physics at LSU.

Supermassive Black Hole

Astronomers responsible for producing the first-ever image of a black hole in 2019 are about to make an announcement about something at the center of The Milky Way on May 12.  Could it be an image of Sagittarius A* our galaxy’s supermassive black hole or the detection of an ancient cosmic string from the dawn of the Cosmos?

The first black hole to be discovered was Cygnus X-1 in 1964. It comprises a black hole and a blue supergiant star orbiting each other. The black hole is accreting from the wind of the blue supergiant, forming a hot disk around the black hole that emits powerful X-rays. The mass of the invisible  companion is calculated to be 8-10 solar masses, much too large to be a neutron star.
