An acoustic black hole was a concept devised by condensed matter physics.
A black hole was, by definition, a region from which even particles moving at the speed of light, such as photons, could not escape.
Then, a region from which phonons could not escape could be called an acoustic black hole.
Have an object move back and forth through a medium at supersonic speed, eventually forming a turbulent flow that could swallow all sound.
It possessed singularity, possessed properties that were difficult to fathom.
This was the so-called "acoustic black hole."
And the means by which an acoustic black hole emitted Hawking radiation was through "phonons."
This coincided perfectly with the Savior Devil King's cultivation method.
Using this cultivation method, scholars simulated black holes and explored some of the properties real black holes might possess.
This could be considered one of Liuyun Sect's rare moments in the spotlight over the past five hundred years.
It was even the first time in all these years that an affiliated sect under Liuyun Sect had received a large batch of equipment orders.
But if acoustic black holes in this world could release phonons, that meant Hawking radiation was also very likely valid in this universe. Black holes were not merely places where things went in and never came out; much information could still emerge into this universe along with Hawking radiation.
If so, the probability of a black hole killing a Precognizer would undoubtedly be much lower.
Perhaps only a Kerr Black Hole with a double Event Horizon could effectively kill a Precognizer.
Of course, those were not the only benefits of acoustic black holes.
They were of great help in the study of black holes.
Of course, humanity still hoped to directly come into contact with black holes.
