Do new calculations describe the "birth of the universe"? Researchers in Japan have developed what may be the first string-theory model with a natural mechanism for explaining why our universe would ...

If we want to describe the Universe as simply and completely as possible, it takes 26 dimensionless constants to get us there. This is quite a small number, but not necessarily as small as we'd like.

How exactly did the universe start and how did these processes determine its formation and evolution? This is what a study ...

As it turns out, it takes 26 dimensionless constants to describe the Universe as simply and completely as possible, which is quite a small number, but not necessarily as small as we like.

However, we do know that the universe is larger than 93 billion light-years across. This is the diameter of the sphere of the “observable universe” that we find ourselves at the center of.

String theory may be our best attempt at a theory of everything, except that it can't describe an expanding universe like ours. Now a radical new twist on the idea could finally fix that – but ...

How cool is it that your article about five numbers that transform our understanding of the universe started on page 42 (13 August, p 42), the number made famous by The Hitchhiker’s Guide to the ...

We know that the universe is expanding, and our understanding of nature based on general relativity and the Standard Model of elementary particles is consistent with this observation. However, these ...

As a member of the University’s Summer Undergraduate Research Fellowship program and a 2021 McHale Fellow, I am conducting theoretical research on how the shape of the universe can explain dark matter ...

Scientists believe we could find missing aspects of our understanding of the universe by looking closely at the signatures of gravitational waves—ripples in the fabric of space-time.

The grand explanation physicists use to describe how the universe works may have some major new flaws to patch after a fundamental particle was found to have more mass than scientists thought ...

We may have already found evidence of an evolving, dynamic kind of dark energy, in the form of the radiation emitted when the first stars appeared in the universe.
