The universe was created 13.7 billion years ago in a blaze of light: the big bang. Roughly 380,000 years later, after matter (mostly hydrogen) had cooled enough for neutral atoms to form, light was able to traverse space ...

(Phys.org) —Adam Falkowski, a physicist working at CERN, on his Particle Physics Blog, is claiming that researchers on the BICEP2 team that uploaded a paper (First direct evidence of cosmic inflation) to the arXiv preprint ...
The recent BICEP2 observations – of swirls in the polarisation of the cosmic microwave background – have been proclaimed as many things, from evidence of the Big Bang and gravitational waves to something strange called ...

(Phys.org) —Physicists Joseph Silk of Institut d'Astrophysique de Paris and Jens Chluba of Johns Hopkins University have together published a Perspective piece in the journal Science, where they discuss the future of cosmological ...
Last month, scientists announced the first hard evidence for cosmic inflation, the process by which the infant universe swelled from microscopic to cosmic size in an instant. This almost unimaginably fast expansion was first ...
