The NewsYet –
Coming fresh on the heels of the first ever photo of one of the giant objects, which are scattered across the Universe, astrophysicists are now several steps closer to understanding how they form and develop.
As they suck in matter such as gas, dust and space debris, they form an accretion disk — a churning mass of super-accelerated particles that are among the brightest objects in the Universe — around them.
It is the accretion disk that can be seen as a blurry halo around the image of the black hole released in April from the Event Horizon Telescope.
But accretion disks are nearly always tilted at an angle to the orientation of the black hole, known as its equatorial plane.
But no model could ever work out how, precisely, that would happen. Until now.
Caused by electromagnetic effect
Crucially, their approach gave them the computing power to account for magnetic turbulence, which occurs when different particles churn at different speeds within the accretion disk.
It is precisely this electromagnetic effect that causes matter to fall to the centre of the black hole.
It’s like a dart hitting bullseye
“If you don’t really aim it will never hit the bullseye,” he said. “In the same way, when (matter) falls into the black hole it has some rotation but this rotation will have nothing generally to do with how the black hole rotates. The two rotations will not know anything about each other.”
