An international team of astronomers has discovered a supermassive black hole in the center of a distant galaxy that does not have enough fuel to feed and make the galaxy shine, so it drags it into darkness, according to the European Southern Observatory ( THAT)
Many galaxies have an extremely bright nucleus fed by a supermassive black hole that generate "active galaxies", which release large amounts of energy and matter into the interstellar medium.
In 1974, Stephen Hawking postulated the existence of a type of radiation that is born in the horizon of events of black holes. The theory is revolutionary, but it has never been proven until now. A team of physicists claims to have demonstrated the existence of Hawking radiation by the equivalent of a laboratory black hole.
The proposal was problematic because, according to the laws of physics of the time and Hawking's own calculations, black holes could not lose mass and become smaller. The physicist reviewed all his calculations and came to the conclusion that Zeldóvich and Starobinski were right. Hawking's proposal to explain the proposal of his Russian colleagues is what is now known as Hawking radiation. The hypothesis is based on the existence of quantum fluctuations in the vacuum that arise as a consequence of Heisenberg's uncertainty principle. These fluctuations create pairs of matter-antimatter that disappear as soon as they are born.
However, when these pairs are born in the event horizon of a black hole, the intense gravity makes those pairs of virtual particles come true. In that case, one of the particles is absorbed by the black hole, and the other is emitted to the outside, taking with it part of the energy of the black hole. The hypothesis is so revolutionary that if it turns out to be true it would shake the foundations of physics as we know it. The problem is that the radiation that Hawking predicted more than 40 years ago is so tenuous that it is impossible to measure with current instruments in black holes that are light years away.
