Although some compelling evidence exists to support the idea that a repulsive force similar to dark energy exists, it has yet to be directly observed or measured. To circumvent this uncomfortable ...

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 ...

Ian G. McCarthy receives funding from UKRI's Science and Technology Facilities Council (STFC). He works for Liverpool John Moores University. Given how unfathomably large the universe is, it is ...

BUFFALO, N.Y. — In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles. Because this behavior is hypothesized to be ...

Plasma is a state of matter that emerges when a gas is heated to sufficiently high temperatures, prompting some electrons to become free from atoms. This state of matter has been the focus of many ...

A new investigation of the structure of galaxy clusters has found it agrees with predictions made by the standard model of cosmology, the best explanation scientists have of the evolution of the ...

JIM PEEBLES is widely known as the architect of modern cosmology – and its nice-guy-in-chief. Awarding his half-share of the 2019 Nobel prize for physics, the committee said he “took on the cosmos”, ...

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 ...

A new study probing the structure and evolution of galaxy clusters shows good agreement with the predictions of standard cosmological models. Cosmologists have found new evidence for the standard ...
