A longstanding goal in physics has been to link general relativity with quantum theory and so unify the forces of nature. Theories of quantum gravity, however, are plagued by the weak theoretical ...

An unprecedented neutrino detection in the Mediterranean has pushed the boundaries of high-energy astrophysics, raising new ...

One of the best-performing models in cosmology is also one with the least physical rationale behind it. Columnist Leah Crane ...

Michael Boylan-Kolchin and others show “early dark energy” might help solve the Hubble Tension and explain why there are more early galaxies than expected. A panel of physicists and astronomers ...

A good chunk of cosmology is riding on whether dark matter exists or not. But what makes us so certain that dark matter is ...

"Atomic clocks bring cosmology and astrophysics down to Earth, enabling searches for ultra-light particles that could explain dark matter in a laboratory." When you purchase through links on our site, ...

Celestial objects known as dark dwarfs may be hiding at the center of our galaxy and could offer key clues to uncover the nature of one of the most mysterious and fundamental phenomena in contemporary ...

The use of atomic clocks could help bring cosmology and astrophysics "down to Earth" by allowing scientists to investigate the mysteries of dark energy and dark matter in the lab. When you purchase ...

A student-led experiment has shown that the search for dark matter doesn’t always require massive infrastructure.

Celebrating the appointment of Professor Lloyd Knox, center, as the new Michael and Ester Vaida Endowed Chair in Cosmology and Astrophysics are, from left: Distinguished Professor Andreas Albrecht, ...

Erik Shirokoff, associate professor in the Department of Astronomy and Astrophysics and senior member of the Kavli Institute for Cosmological Physics (KICP), passed away on Thursday, January 26, ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...
