American astrophysicists were able for the first time to track the fate of light particles that appeared near a black hole and managed to escape by falling into it.
“We followed the approach of light particles from the black hole, and then we saw their attempt to escape the force of their gravity. Theorists had predicted it, but no one has observed it yet,” said Riley Connors, an astronomer at the University from California, who published an article in The Astrophysical Journal. .
The gravitational pull of ordinary and giant black holes is mentioned to be so great that it prevents any space object from exceeding it without exceeding the speed of light. This means that any space object or any type of radiation cannot cross the event horizon as a barrier that delimits the effect of the gravitational force of the black hole.
However, Soviet astrophysicists Rashid Sionaev and Nikolai Shakura demonstrated that some light particles approaching an irreversible point could escape capture from the black hole. To achieve this, you must go in a certain direction relative to the horizon line. In this case, the gravitational force of the black hole accelerates it and helps it escape beyond its limits.
Conors and his colleagues witnessed such a flight for the first time, after analyzing observations made by the RXTE Space Telescope on the double star XTE J1550-564 in the constellation “Triangle” which is 14.4 thousand light-years away from Earth. .
