In an article published in the Proceedings of the National Academy of Sciences, researchers from Aalto University and the VTT Technical Research Centre of Finland showed experimentally that vacuum has properties not previously observed. According to the laws of quantum mechanics, it is a state with abundant potentials. Vacuum contains momentarily appearing and disappearing virtual pairs, which can be converted into detectable light particles.
The researchers conducted a mirror experiment to show that by changing the position of the mirror in 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.
'If we act fast enough, we can prevent the particles from recombining -- they will then be transformed into real particles that can be detected', says Dr. Sorin Paraoanu from the Aalto University School of Science.
