Black holes can reflect echo
Source:Discovered in 2017, a black hole can violate all laws of usual physics
When two neutron stars collided far away in space, the gravitational waves arising from such a powerful concussion, headed in the direction of the Earth. Worked his way into a few millions and billions of kilometers, the waves were discovered in 2017, when scientists, looking at the record of gravitational waves, found evidence of the existence of black holes, violating the laws of physics. According to an article published on the portal , the discovery of this unusual object casts doubt on the General theory of relativity. So what's wrong with that found a black hole?
the Strangeness of black holes
In the General theory of relativity — this simple features: infinitely compressed singularity or specific points of matter, surrounded by a smooth event horizon, through which can pass neither light nor energy nor any other physical substance. Still every bit of data collected by scientists of black holes, maintained that the familiar and the familiar model.
But in the 1970's, Stephen Hawking wrote a series of works in which it is assumed that the boundaries of black holes is not so smooth. Instead they are heavily eroded due to a number of phenomena associated with quantum mechanics, which allow to evaporate. In subsequent years, several other models of black holes, these smooth, sophisticated event horizons would be replaced by more subtle and vague membranes. In one of his latest theories, physicists predicted that the fog will be especially intense around the newly formed black holes and will be substantial enough to reflect the gravity waves, producing a peculiar echo. Discovered in 2017, a black hole can serve as a genuine proof of this hypothesis. So, experts say that what was previously considered dumb space monster, attractive in its surroundings, even the smallest particles of light and time itself actually rings like an echo of a bell, thus destroying the simple .
the Collision of two neutron stars may lead to the emergence of a black hole
Niaes Afshordi, a physicist from the University of Waterloo in Canada, says that according to the theory of relativity, near should be no loose material that reflects gravitational waves. Even those black holes that surround themselves with discs of material, usually have an empty area directly around their event horizon. However, the data from the existing detectors of gravitational waves show that this usual rule does not always work. Discovery space “echo” in this case is a direct proof of the falsity of this theory.
However, not all experts support the idea that we would soon have to rethink the conventional knowledge of physics. Maximiliano izi, an astrophysicist at the Massachusetts Institute of technology, believes that even if the echo does exist, scientists can not with absolute precision to prove that the object that caused the space echo really was a black hole. Instead, it could arise and any other exotic object formed after the collision . So, this short-lived intermediate object could be a remnant from hypermassive star, collapsing after a collision for a second or so. The result of such phenomena was discovered echo, come down to Earth after hundreds of millions of light years after the cosmic event.
