Section J.I. Latorre with L. Verde: Viatjar al passat?.

The night of October 22-23, 2019, a new instrument installed in a telescope in Arizona made its first light observation pointing its 5,000 eyes of optical spectra to the cosmos. The device, which will observe a record figure of galaxies and quasars, tested its unique vobservation of the Universe.

Astrophysicists point to a crack in the standard model of Cosmology. The precision of new observational results on the early and late Universe have increased and researchers suggest the requirement of new physics to fit the new data. This is the main conclusion of a study published in Nature Astronomy and signed by researchers from the University of Barcelona, the University of California (United States) and the Johns Hopkins University (Maryland, United States).
