Speed ??supermassive black hole is equal to the speed of light

It is believed that huge black holes are the only powerful and heavy objects with mass, reaching millions and even billions of solar masses, which are detected by researchers at the centers of many galaxies.

Surrounded by a dense disk of gas and dust that supermassive black holes are actively attract the matter. The substance, "fallen" into this funnel, is heated by radiating waves actively in different bands, even the most demanding. Telescopes XMM-Newton and NuSTAR observed at the galactic center supermassive black hole NGC 1365 on such - X - waves.

Black holes in the universe, as the researchers note, are the most simple objects: they can be fully described by identifying three main characteristics: mass, charge and spin rate. However, supermassive black holes are still a big mystery, as long as specialists really do not even know where they come from and why it was placed in the centers of galaxies.

Meanwhile, set the speed of rotation of holes by using observations of X-ray excited ions of iron in the accretion disk, which rotates around the hole. Earlier sure to bring results such complex measurement was not possible, so the work done by XMM-Newton and NuSTAR, was the first.

The results showed astounding amount uglovoyskorosti supermassive black hole in NGC 1365. It reaches 84% of the maximum possible, the speed of light. So, the speed with the prefix "super" corresponds to a supermassive black hole.
