Detection of the cosmic gamma ray horizon: Measures all the light in the universe since the Big Bang
Riverside CA (SPX) May 27, 2013
How much light has been emitted by all galaxies since the cosmos began? After all, almost every photon (particle of light) from ultraviolet to far infrared wavelengths ever radiated by all galaxies that ever existed throughout cosmic history is still speeding through the Universe today. If we could carefully measure the number and energy (wavelength) of all those photons - not only at the present time, but also back in time - we might learn important secrets about the nature and evolution of the U ... read more
