If there's one thing "every schoolgirl knows" about Einstein and his Theory of Relativity, it's that the speed of light is constant. The speed of light is the very keystone of physics, the seemingly sure foundation upon which every modern cosmological theory is built, the yardstick by which everything in the universe is measured.
Yet today, a revolt is brewing. A group of brilliant physicists and astronomers have risked their scientific reputations to question the validity of Einstein's idea. Could the speed of light change?Might it in fact be gradually slowing down?If so, it will herald a revolution in our understanding of the Universe as profound as that initiated by Einstein himself nearly a century ago.
