Scientists Discover Vortex Around Black Hole Spinning at 70 Percent the Speed ​​of Light

Astronomers have measured the spin of five supermassive black holes located around 10-11 trillion light-years from Earth — and the results reveal that they are moving at staggering speeds.

Astrophysical Journal the event horizon of one of these stellar objects is spinning close to or at the speed of light-around 670 million miles per hour. (The event horizon is the point of no return around a black hole which is not even light can escape.)

The collection of dust and gas around a black hole — known as an accretion disk— becomes superheated to many millions of degrees as it gradually gets sucked it, generate X-ray light that astronomers can detect using specialized observatories.

of our sun. These types of supermassive black holes that rapidly ingest matter from swirling disks or material ̵

1; known as quasars – are some of the brightest objects in the universe. However, the quasars in question are so far away, astronomers use of a natural phenomenon known as "gravitational lensing" in order to study them.

With just the right alignment, the immense mass of large objects, such as galaxies, in the intervening space can be found and distorted the light coming from even more distant objects directly behind them. This can magnify or produce multiple images with these more distant objects, making them easier to study. With the help of NASA's Chandra X-ray Observatory, the astronomers used this technique to work out the spin rate of the distant black holes. The astronomers found that the X-rays are quasars that are coming from a region of the accretion disk that is only slightly larger than the event horizon itself. As a result, they conclude that the black holes must be spinning extremely rapidly.

These observations are significant because while we have been able to measure the mass of black holes with relative ease in the past, determining their spin rate has been tested. ask dad harder.
