EXCERPT:
Astronomers may have found some of the strongest evidence yet for one of quantum mechanics’ strangest predictions: even apparently empty space can influence the way light travels.
Known as ‘vacuum birefringence’, the phenomenon was predicted nearly 90 years ago by Werner Heisenberg, one of the pioneers of quantum mechanics. His work suggested that a perfect vacuum is not truly empty. Instead, it should contain ‘virtual particles’ that briefly appear and disappear.
Researchers, including Dr. Marcus Lower from Swinburne University of Technology, investigated this long-standing quantum mystery by studying a magnetar, a rare type of neutron star that possesses the strongest magnetic fields known in the universe.
Their observations may represent the first detection of vacuum birefringence occurring within a magnetar’s extraordinarily powerful magnetic field. If confirmed, the result could give scientists a new way to investigate the quantum universe. The findings were published recently in Nature.
