For the last few decades, researchers have been studying what the universe looked like in its first seconds. It is generally ...

The ‘inflationary’ model of cosmology explains many large-scale features of the Universe as the result of a primordial period of exponential, almost instantaneous cosmic expansion called inflation.

A novel theory suggests that the current expansion rate of the universe is not fixed, but was in fact quite different in the ...
