How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the ...

Two new studies have measured the expansion of the universe in our immediate cosmic neighborhood using a novel method that ...

For almost a century, we have known that the universe is expanding. For several decades, evidence has suggested that the expansion of the universe is accelerating. Crucial to those estimates were the ...

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

For years, cosmologists have argued over a simple question with an awkward answer: How fast is the universe expanding right ...

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 closer look at the Lambda Cold Dark Matter model, its core components, supporting evidence, and why new observations are ...
