When matter crosses the invisible boundary, it disappears from our Universe.
Astrophysicists have considered the case in which a black hole is a supermassive object. These celestial bodies are found in the centers of galaxies, but they surrounded was considered to be the event horizon — an invisible sphere, from which can not escape the light. However, scientists have replaced the horizon on a hard surface. Then they simulated what would happen to matter if it crashed into a black hole, and not absorbed by it.
The researchers found that in this case, the star would have exploded, and its substance would surround the black hole. While it would be possible to observe the outbreak for months or several years.
However, the astronomical data obtained using a system of telescopes Pan-STARRS (Hawaii), demonstrated the absence of such phenomena. According to scientists, if black holes really were “hard”, it would be possible to register about ten collisions of stars with them for 3.5 years.
At the same time, the researchers admit that, if the black hole is heavy enough, the light from the flash can be indistinguishable to be used in the research work of telescopes. This is due to a phenomenon known as gravitational red shift. As the electromagnetic wave away from a massive body, their frequency shifts in the infrared region of the spectrum.
Other scholars argue that there are much more compelling evidence for the existence of the event horizon. Astrophysicist Grant Tremblay (Tremblay Grant) compared the results of a new study with the statement that the chest pain is not associated with a heart attack, otherwise the patient is already dead. He believes that the work of Texas scientists is interesting, but it is only an additional evidence for the existence of black holes, predicted by the equations of albert Einstein.
