Black holes commit "cosmic robbery" to feed their deadly deadly rays.



Black holes are notoriously greedy and prone to feasting on anything lucky enough to be nearby.

But they also emit "death rays" made of charged particles that project into space at the speed of light.

Scientists now believe that these jets are caused by a process they compared to a "cosmic robbery" fueled by the spin of the hole.

Alexander Philippov, an associate researcher at the Center for Computational Astrophysics at the Flatiron Institute in New York, conducted "a more detailed view of the processes that feed the jets of a black hole."

"No one has been able to push these simulations so hard in curved space-time," he said.

His work focuses on wiring a black hole, which then "distorts and distorts the surrounding tissue of space and time" because of its gigantic mass.

The simulation suggests that the magnetic fields at the poles of the holes become "curled up and sprout outward, throwing jets of particles into space" at the speed of light.

It is unlikely that a living organism survives being struck by the rays of a black hole.

"They are the very own Death Star rays of nature – ultra-powerful energy jets that come out of the vicinity of black holes like the deadly rays of the Star Wars super weapon," explained the University of Southampton in 2017.

A theory suggests that they develop into the "accretion disk" – the matter sucked into the orbit of a growing black hole – Extreme gravity inside the disk twists and stretches magnetic fields, squeezing hot magnetized disk material called plasma until it erupts in the form of magnetic pillars of opposite orientation along the rotational axis of the black hole.

'Plasma travels along these focused jets and gains tremendous speed, firing through vast tracts of space. At some point, the plasma begins to glow, but how and where it occurs in the jet was debated by scientists.
