How did the early universe evolved over time into its present form? Astronomers begin to unravel mysteries of the universe by measuring light from Big Bang. A team of astronomers have gone ahead and found a way to measure the light in the universe. They are beginning to unravel the mysteries of the universe by studying some of the oldest known light: extragalactic background light (EBL)-that was released immediately after the Big Bang. Until now, the accurate documentation of EBL, the most important measurement for scientists was never recorded. The presence of EBL proves that the galaxies that are visible today are because of the light. A newly published report by Alberto Domínguez, a postdoctoral researcher in the Department of Physics and Astronomy at the University of California, Riverside, for the first time attempts to identify the key physical attributes of EBL and provides astronomers a method that is capable of measuring the elusive light. EBL is a collection of the photons emitted just after the Big Bang - is as fundamental to cosmology as measuring the heat radiation resulting from the Big Bang. By better understanding EBL, the scientists could solve the secrets of the nature and evolution of the universe along with how the universe is expanding and, possibly, how it will end.
