In this proceedings I briefly present the status of the global 21-cm signal
detected by EDGES in March 2018. It is organized in three parts. First, I
present the EDGES experiment and the fitting procedure used by the
collaboration to extract the tiny 21-cm signal from large foregrounds of
galactic synchrotron emission. Then, I review the physics behind the global
21-cm signature and I explain why the measured absorption feature is anomalous
with respect to the predictions from standard astrophysics. I conclude with the
implications for Beyond Standard Model (BSM) physics coming from the EDGES
discovery.
