"It highlights gravity's possible hidden complexity and invites a reevaluation of where dark matter effects originate." ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing ...

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 ...

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 ...

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

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 ...

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 ...

This release is available in German. As modern cosmologists rely more and more on the ominous "dark matter" to explain otherwise inexplicable observations, much effort has gone into the detection of ...

An expert shares his personal reminiscences of the evolution of the subject of cosmology over six decades. He tells of the increase in our confidence in the standard model of cosmology to the extent ...
