Jeff Steinhauer, a physicist at Technion University in Israel, has created an acoustic black hole and observed particles slipping out of its grasp, providing the strongest evidence to date of one of Stephen Hawking’s most famous predictions. In 1974, Stephen Hawking predicted that black holes might not be the bottomless pits we imagine them to be. According to Hawking’s calculations, some information might escape black holes in the form of energy, or Hawking radiation. Here's how it works: Throughout the universe, matter-antimatter pairs of particles are constantly flickering in and out of existence (because matter and antimatter quickly annihilate each other). But if one of these particles is
Black holes remain one of space's greater scientific mysteries, but thanks to the artificial replication of the phenomenon in a lab, we could be a step closer to understanding their strange radiation, first described by Stephen Hawking decades ago. Independent experimental physicist Jeff Steinhauer of the Technion-Israel Institute of Technology in Haifa created an artificial black hole that appears to emit the so-called "Hawking radiation," named for a theory proposed by Hawking in the mid-1970s. Using ultracold atoms, Steinhauer appeared to be able to mimic a black hole's "event horizon," or "the point beyond which the gravitational pull is too strong for even light to escape," Nature explains.
IRVINE, Calif., Aug. 15 (UPI) -- New research confirms the science behind a previous study suggesting the existence of a fifth force of nature. Last year, a group of Hungarian researchers reported the possible discovery of a new type of subatomic particle. Scientists identified a radioactive decay anomaly among the results of their particle acceleration experiments. The anomaly suggested the presence of light particle 30 times heavier than an electron. The goal of those experiments was to find dark matter, but scientists weren't sure exactly what kind of particle they'd observed. "The experimentalists weren't able to claim that it was a new force," Jonathan Feng, professor of physics and astronomy
When the Higgs boson was discovered in 2012, the excitement in the physics world was palpable. The news featured on the front pages of newspapers, and it made the British theoretical physicist Peter Higgs an instant celebrity. Higgs had predicted that a boson, a fundamental particle of the universe, must exist to explain the world as we see it, and after 50 years of experiments, his conjecture was proven correct.
