Every astronomy textbook tells us that soon after the Big Bang, there was a period of exponentially accelerating expansion called cosmic inflation. In a tiny fraction of a second, inflationary ...

Researchers have discovered a new generic production mechanism of gravitational waves generated by a phenomenon known as oscillons, which can originate in many cosmological theories from the ...

The approach parallels the way cosmologists go about inferring the history of the universe. Like fossils, astronomical objects are not randomly strewn throughout space. Rather, spatial correlations ...
