Gravitational wave background discovered by NANOGrav as evidence of a cyclic universe
Nick Gorkavyi
Abstract:The consortium NANOGrav discovered the isotropic gravitational wave background (GWB) with an amplitude of h ∼ 10 −15 and a frequency of f ∼ 10 −8 Hz using observations of millisecond pulsars. We hypothesize that the GWB is relic radiation left over from the merging stellar mass black holes (SBHs)during Big Crunch at z ∼ 10 10 . The relic gravitational waves are similar to the gravitational waves with f ∼ 10 2 Hz discovered by LIGO in 2015, taking into account a decrease in frequency by a factor ∼ 10 10 due to … Show more
