The Atacama Cosmology Telescope in Chile not only confirmed one of the greatest mysteries in the universe—it also ruled out ...

"It means cleaning house, narrowing the viable paths forward, and no longer spending energy on what are evidently dead ends." ...

A new study, published on Arxiv, has deepened the cosmic puzzle surrounding the “Hubble tension,” an ongoing debate about the universe’s expansion rate. The findings come from the Atacama Cosmology ...

A new theory for the origins of dark matter suggests that fast-moving, neutrino-like dark particles could have decoupled from ...

In the leading model of cosmology, most of the universe is invisible: a combined 95% is made of dark matter and dark energy.

What are the mysterious dark matter and dark energy that seem to account for so much of our universe? Why is the universe expanding? For the past 30 years, most cosmologists have looked to the ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

Mr. Sundman earned a Masters of Science degree through the Department of Engineering Physics at Helsinki University of Technology. There, Stig became interested in elementary particle physics, with ...
