Sense（1）

An international group of researchers has developed a new way to measure accurately the extragalactic background light (EBL) that fills the universe. The technique involves measuring the attenuation of high-energy gamma rays from distant blazars and it could improve our understanding of how galaxies form and evolve, as well as how the universe has expanded since the Big Bang
