Not everything gets sucked into a black hole: Report
Researchers have successfully been able to calculate the radius of a black hole.
Black holes, those massively dense, collapsed stars that can't be seen by the naked eye are supposed to have a gravitational pull so strong that not even light can escape.
But a scientist from the Indian Institute of Science Bangalore and his student have a new theory: Not everything is sucked into a black hole. In fact, gases can even be repelled from the dead stars, according to a new study in the international journal Physical Review Letters.
"First we were working on how stars collapse and end up into black holes," Indrani Banerjee, a PhD student of physics, told the Times of India. "During the research, the thought of discovering the properties emerged," she said.
The reason is that as a black hole pulls matter closer to its center, the material heats up. That heat causes particles to move faster, and that movement is enough to counteract the black hole's gravity.
