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 ...

The UC Irvine Department of Physics and Astronomy has established a research program in modern cosmology – an entirely new field of research at the university. The new program builds upon the ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Dark matter remains one of the most compelling enigmas in modern cosmology. Although it does not emit light, its gravitational influence is essential for the formation and evolution of cosmic ...

The Atacama Cosmology Telescope in Chile has released its final batch of data after 15 years — and it proves that the Hubble ...

"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, ...

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 ...

The University of Chicago’s Kavli Institute for Cosmological Physics has secured $10 million in new funding through two gifts: a $5 million gift from an anonymous alumnus and his wife and a match of ...

As part of the Decadal Survey on Astronomy and Astrophysics (Astro2020), the Panel on Cosmology will identify and articulate the scientific themes that will define the frontier in cosmology research ...
