A New Discovery About the Strange Interaction Between Cosmic

However, not all streams of light entering the swirling matter disk region of the black hole can escape easily. A new study, published in The Astrophysical Journal, provides evidence that light must be very 'hard' to escape from the swirling matter disk, some of which are affected by animated by the black hole's gravitational pull, turning back, and finally bouncing off the physical disk and 'escaping'.

'We observed that light coming from very close to the black hole was trying to escape, but was pulled back like a boomerang by the black hole. This is something that has been predicted since the 1970s, but until now it has been fully observed, '' said astronomer Riley Connors, the expert in charge of the research team.

The scientists obtained these new findings by combining at the same time a large amount of observational data stored from NASA's Timi Explorer (RXTE) mission, which ended in 2012. In particular, the research team Special attention paid to a black hole being orbited by a star almost like the sun. Together, this 'couple' is called XTE J1550-564. The black hole "nurtures" the star, pulling matter onto a flat structure around it called a accretion disk. By observing the X-rays emitted from the disk as spiral light is directed toward the black hole, the team has found markers that show the light has been bent toward the disc and reflected.

'Basically accreting material discs can emit light themselves. Cosmological theorists have previously predicted which part of the light will go back on the disk, and now, for the first time, we have been able to confirm those predictions. ' said.

This new observation provides another indirect confirmation of Albert Einstein's general theory of relativity, and will also help to understand future measurements of the rate of black hole rotation - something that is still not well understood..
