(Phys.org)—Physicists have discovered a surprising consequence of a widely supported model of the early universe: according to the model, tiny cosmological perturbations produced shocks in the radiation fluid just a fraction ...
Now that scientists have confirmed the existence of gravitational waves, a NASA team is set to search for a predicted signature of primordial gravitational waves that would prove the infant universe expanded far faster than ...

Einstein was right – changes in gravity do spread as waves through space. The LIGO experiment detected such waves from a collision between two black holes with masses of about 36 and 29 times that of the sun (described ...
