If we look at the sky, we see an infinity of stars, sometimes a planet or even comets but, above all, we see darkness. Where did the light of that infinity of stars go? Why doesn’t it illuminate our nights as well as the sunlight bathes our days?

With this video “Why is the night dark?”, the Instituto Galego de Física de Altas Enerxías (IGFAE) inaugurates a series of videos with the physicist Darío Lago, creator of the popular science Youtube channel in Galician O Son das Ideas, in which we will dive deep into the origins of our Universe.

Script: O Son das Ideas, and IGFAE researchers José Edelstein, Javier Martín and Imanol Corredoira.
Animation and voice-over: O Son das Ideas.

This video was co-financed by the Operational Program FEDER Galicia 2014-2020.
