Let There Be Light...In a Vacuum

Facebook X LinkedIn Email
GOTHENBURG, Sweden, Nov. 17, 2011 — The quantum mechanical principle which states that a vacuum is not empty space, but instead teeming with particles that flit in and out of existence, has been observed for the first time as photons were coaxed to leave this virtual state and captured as measurable light. According to the 40-year-old principle, known as the dynamical Casimir effect, if virtual photons are allowed to bounce off a mirror moving at near light speeds, they will become real photons. Chalmers University of Technology scientist Christopher Wilson and co-workers achieved the desired result, with some...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    quantum mechanics
    The science of all complex elements of atomic and molecular spectra, and the interaction of radiation and matter.
