The anomalous 21-cm absorption at high redshifts
Abstract The EDGES collaboration has reported the detection of a global 21-cm signal with a plateau centered at 76 MHz (i.e., redshift 17.2), with an amplitude of $$500^{+200}_{-500}$$ 500 - 500 + 200 mK. This anomalous measurement does not comport with standard cosmology, which can only accommodat...
