A terrific piece of research – highly innovative – see https://doi.org/10.1103/PhysRevResearch.4.043084 … and see also https://phys.org/news/2022-11-synthetic-black-holes-real.html … to make a synthetic black hole, take a chain of atoms and change how easy it is for an electron to jump between each atomic site. You also have to mimic the warping of space time in the presence of a black hole. Doing this enables you to look at the physics of a black hole in a laboratory.
Researchers at the University of Amsterdam have demonstrated that elusive radiation coming from black holes can be studied in a laboratory. Understanding black holes, they say, is key to unraveling the cosmos – because they represent the limits of two of the best tested theories of physics. These are general relativity and quantum mechanics, at either end of the spectrum. To fully describe black holes, we are told, we would need to stitch these two theories together and form a theory of quantum gravity.
Scientists are fascinated by black holes. At https://phys.org/news/2022-11-black-holes-dont-power-gamma-ray.html … we are told black holes don’t always power gamma-ray bursts. These have been detected by satellites orbiting the earth as luminous flashes of gamma ray radiation. This piece of research comes from the University of Bath – and collaborators elsewhere.
At https://phys.org/news/2022-11-death-star-reveals-midsize-black.html … astronomers say they have discovered a star being ripped apart by a black hole in a distant galaxy. The Hubble Space Telescope was used to peer at the aftermath. They found a mid sized black hole lurking there. They then assume it had gobbled up the star, producing a flash of radiation in the process.
