A cutting-edge supercomputer simulation created a pocket black hole with a suitable accretion disk, and the experiment didn't unfold as expected.
run counter to the traditional idea that a black hole dines on its accretion disk in a relatively leisurely manner. Instead, the team found that the simulated black hole scarfed down matter voraciously and effectively made a mess of its plate in the process.quasar
“Classical accretion disk theory cannot explain this drastic variation,” said Nick Kaaz, a graduate student at Northwestern University, inUnder the classical theory, an accreditation disk rotates in sync with a black hole and gradually falls below its event horizon, the point beyond which no light can escape. This takes a long time, between hundreds or even hundreds of thousands of years.
The simulated black hole yanked and pulled the very fabric of space around it, which caused the accretion disk to wobble. As it warped, gas from different areas collided and emitted powerful bursts of light. The outer section collided with the inner one, and the added mass helped the inner to fall into the center of the black hole. Then the outer flowed into the empty inner section, and the cycle started over.
