Recent detection of stochastic gravitational wave background by pulsar timing arrays (PTAs) missions opens a new window of testing fundamental physics laws at energy scales far beyond what is reached by particle physics experiments and/or by astrophysical observations; In my talks I will addresses such early-universe sources as primordial hydro and magnetic turbulence which are possibly present at the the epoch of the QCD phase transition Additionally I will discuss the PTAs data in the context of massive gravity independently of the gravitational wave signal origin (astrophysical or cosmological)..
