Virtual Photons Become Real in a Vacuum

Facebook X LinkedIn Email
ESPOO, Finland, Feb. 26, 2013 — By changing the position of a mirror inside a vacuum, virtual particles can be transformed into real photons that can be experimentally observed. In a vacuum, there is energy and noise, the existence of which follows the uncertainty principle in quantum mechanics. These virtual particles in the vacuum can momentarily appear and disappear, and can be converted into detectable light particles. Now, researchers at Aalto University and the VTT Technical Research Center of Finland have showed experimentally that vacuums have properties not previously observed. They demonstrated that by...Read full article
