A video of a black hole absorbing spaghetti-like stars, simulated over the course of a year on a supercomputer, is released

Black holes are super-dense, massive objects in space, and it is believed that not only matter but even light cannot escape them. It is believed that matter captured by a black hole is stretched into a long, thin shape like spaghetti by the tidal force of strong gravity , a phenomenon known as 'spaghettification .' A research team led by Donnel Price of Monash University simulated this spaghettiification phenomenon using a supercomputer.

When a star is sucked into a black hole, it is subjected to strong gravity and stretched into long, thin threads. However, not all of the spaghetti-like stars are sucked into the black hole; only 1% of them are actually sucked in. The remaining 99% of the material is spewed out into space.

It is difficult to study supermassive black holes, for which the general law of gravitation does not apply, and in order to simulate spaghettification on a computer, it is necessary to encompass the effects of the theory of general relativity , which has not yet been studied.

But with the help of the supercomputer Ngarrgu Tindebeek , the team was able to simulate what a spaghetti-like star would look like, a process that took more than a year to create.

Below is a simulation of a spaghetti-like star created by the research team.

A star that is sucked into a black hole leaves a trail as it is sucked into the black hole.

However, most of the material is released into space.

The released material is gradually absorbed.

It took roughly a year for most of the material to be incorporated.

The video below is a close-up simulation of matter being ejected from a black hole.

'Through this simulation, we were able to ascertain the existence of the spaghettification phenomenon and the reason why black holes shine so brightly,' the research team said.
