The astronomers test the basic principles of a black hole to seek whether the matter completely vanishes when it was pulled into the supermassive black hole. Their finding established another successful test for Einstein general theory of relativity.
The research from University of Texas at Austin and Harvard University has concluded the existence of event horizon. According to the official news release from UT Austin, they turn the idea of the existence of event horizon into an experiment.
The research about of the existence of event horizon has been published in the journal Monthly Notices of the Royal Astronomical Society. Up to now, the existence of event horizon has never been proven, therefore the team of astronomers from Austin and Harvard tested the modified theories of General Relativity, the Albert Einstein's theory of gravity. They tried to find a strange supermassive black hole that is able to avoid gravitational collapse to a singularity surrounded by the event horizon.
Since the singularity does not have a surface area, an object that hit the black hole will hit a hard surface and destroy itself. The scientist, led by a Professor of Astrophysics at the University of Texas at Austin, Pawan Kumar tested the theory of the existence of event horizon by searching for a star that hit a supermassive object at the center of a galaxy. The team, which consist of Kumar, his graduate student Wenbin Lu and his colleague from the Harvard-Smithsonian Center for Astrophysics, Ramesh Narayan,
“We estimated the rate of stars falling onto supermassive black holes. We only considered the most massive ones" Lu said about the search for the existence of event horizon. "There are about a million of them within a few billion light-years of Earth.”
They searched the archive Pan-STARRS in Hawaii, which has recently completed a survey of the northern hemisphere sky. The team did not find any evidence of a light signature of star hitting the supermassive black hole. They conclude that the stellar disruption supports the existence of event horizon in the black hole during the collision of the supermassive black hole and a star.
