Physicists have discovered that the ring of photons orbiting a black hole exhibits a special kind of symmetry, hinting at a deeper meaning. The photon ring, which glows orange in this visualization of light flowing around a black hole, contains a succession of images of the entire universe. Meer weergeven Part of the excitement about the photon ring is that, unlike the event horizon, it’s actually visible. In fact, Strominger’s U-turn toward these rings happened because of a photograph: the first-ever image of a black hole. When … Meer weergeven Photons that make a single U-turn around a black hole and then zip toward Earth would appear to us as a single ring of light. Photons that make two U-turns around the hole appear as a fainter, thinner subring within the first … Meer weergeven Strominger and company’s hunch that the holographic dual lives in or around the photon ring has been met with skepticism by some quantum gravity theorists, who see it as too … Meer weergeven Historically, conformal symmetry has proved a trustworthy guide in the search for quantum systems that holographically map onto systems with gravity. “Saying conformal symmetry and black hole in the same … Meer weergeven http://people.uncw.edu/hermanr/BlackHoles/Kerr_Metric_II.pdf iowa county wisconsin register of deeds https://dfineworld.com
