Astronomers have released the most ambitious cosmic map assembled so far, confirming that matter in the Universe is less ...

Observations of the thermal energy in a baby galaxy cluster 12.4 billion light years away suggest much more energetic early ...

Recent observations create a puzzle for astrophysicists: since the big bang, less galaxy clusters have formed over time than was actually expected. Physicists from the university of Bonn have now ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

In my opinion, the theory of evolution by natural selection is one of the most elegant and by far one of the most encompassing theories humanity has ever come up with. Even though it was originally ...

For decades, the prevailing cosmological model has placed dark matter and dark energy at the center of our understanding of the universe’s structure and evolution. These invisible components were ...

Dark matter might have had a turbulent youth. According to an international team, this invisible substance may have formed at ...

What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open ...

For decades, the cosmological field was working under the assumption that, after the universe began in a hot dense soup of energy that expanded in the Big Bang, it continued to expand, forming the ...

Everything in the universe has gravity — and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...
