That’s because general relativity, proposed by Albert Einstein, readily explains the effects of gravity on large-scale phenomena like people, planets, stars, and even galaxies. Glowing Black Hole May Help Unite General Relativity and Quantum MechanicsĪlong with lending support to Hawking’s seminal work, the new experiment may offer tantalizing evidence that helps physicists solve the holy grail of science, uniting general relativity and quantum theory. In short, this type of performance by the particles that are entangled across the simulated black hole’s event horizon appears to indicate the presence of Hawking radiation. This was an exciting result, since the heat produced–that is, radiation–was a match for the theoretical conditions along the event horizon of a black hole under circumstances where portions of the atomic “chain” extended beyond it in the simulation. However, when the researchers produced changes in the fields of these electrons, the overall temperature of their simulated event horizon would rise. researcher at the University of Amsterdam in the Netherlands, and co-authored by researchers from Germany, Finland, and France, the research explaining the creation of a simulated black hole in a lab that started glowing is summarized in the journal Physical Review Research.īy employing a chain of atoms, the team was able to generate the conditions of a black hole’s event horizon, where they found that fine tuning the movement of electrons observed leaping from atom to atom along the chain caused certain properties to vanish. Researchers Find Hawking Radiation During Black Hole Simulation Still, their results seem to support Hawking’s prize-winning work. Instead, they created what is known as an “analog,” which is a fancy way of saying they used powerful computers to simulate the mathematics of a black hole. Of course, the researchers behind this latest find didn’t actually create a real-world black hole in the lab (as it would have devoured the lab, the planet, and maybe even the entire solar system). Now, in this latest effort to simulate a black hole in the lab, researchers say it similarly produced telltale signatures that seem to support Hawking’s conclusions. Years later, astronomical composite images of the area around a black hole within the supergiant elliptical galaxy M87 produced a visualization of a glowing area seemingly surrounding it, appearing to lend support to Hawking’s theory. Hawking ultimately challenged this assumption way back in 1974 by postulating that the intense power of the black hole was likely disturbing the area of space/time around it, which, in theory, would emit a form of electromagnetic radiation now named for the famed physicist. Historically, astronomers and cosmologists believed that the intense gravity created by a black hole was so powerful that nothing could escape its grasp, not even light. Some Things may Escape Black Holes after all The researchers behind the incredible experiment say that the glow potentially indicates the presence of a phenomenon described by famed scientist Stephen Hawking known as Hawking Radiation and may even point the way toward a unified theory of gravity. The researchers used Durham's DiRAC COSMA8 supercomputer to run hundreds of thousands of simulations of light travelling the same path, each time with a black hole of a different mass in the way.A team of physicists simulated a black hole in the lab, and then it suddenly started glowing. The Hubble pictures showed light from another galaxy behind Abell 1201 was reaching Earth in a way that indicated it was bending around an extremely massive object along the way - creating a "lensing" effect in which the more distant galaxy was both magnified and seemingly multiplied around a curved edge.Īstronomers believe every large galaxy has a black hole of at least supermassive size (more than 100,000 times the mass of the Sun) at its centre. Researchers from the United Kingdom's Durham University and Germany's Max Planck Institute discovered the black hole using an innovative technique combining supercomputer simulations with high-resolution pictures taken by the Hubble Space Telescope. The rare "ultramassive" black hole sits at the centre of Abell 1201, a supergiant elliptical galaxy residing in a galaxy cluster of the same name, about 2.7 billion light-years from Earth.
