Researchers test speed of light with greater precision than before

Researchers test speed of light with greater precision than before—14 September 2015

In research supported by the ARC, researchers from The University of Western Australia and Humboldt University of Berlin have completed testing that has effectively measured the spatial consistency of the speed of light with a precision ten times greater than ever before. The stringent testing also confirmed a core component of Einstein’s theory of Relativity known as ‘Lorentz symmetry,’ which predicts that the speed of light is the same in all directions.
