WebJul 24, 2013 · But as these photons with tiny mass travel at nearly the speed of light, time dilatation must be accounted for to obtain their lifetime in our frame of reference, for visible light – and this was calculated to be 10 18 or a billion billion years. Improving this limit might be difficult until new studies can probe the early universe further. WebConsideration of these unexpected behaviours led Albert Einstein to formulate in 1905 a new corpuscular theory of light in which each particle of light, or photon, contains a fixed …
