Princeton University physicist Curtis Callan will give a free public lecture on cosmology and particle physics on Monday, April 25, at 7 p.m. at the University Inn and Conference Center, 611 Ocean ...

Astroparticle physics and particle cosmology represent converging disciplines that strive to understand the universe from its largest structures down to its most fundamental constituents. In this ...

Dark matter has bewildered scientists for centuries. It makes up most of the universe’s matter, but it can’t be seen directly ...

Cosmologists face a dilemma. The rise of quantitative cosmology, exemplified by the release of new data in March on the cosmic microwave background from the WMAP satellite (see pp16-19; print version ...

No matter how elegant your theory is, experimental data will have the last word. Observations of the retrograde motion of the planets were fundamental to the Copernican revolution, in which the sun ...

A theory that unites quantum mechanics and general relativity claims that there was no first moment in time, but it still agrees with the predictions of classical cosmology. It's in the stars One of ...

For the past few years, a series of controversies have rocked the well-established field of cosmology. In a nutshell, the predictions of the standard model of the universe appear to be at odds with ...

“This year’s Nobel laureates in physics have painted a picture of a universe far stranger and more wonderful than we ever could have imagined.” Theoretical physicist Ulf Danielsson from Uppsala ...

THIS YEAR’S Nobel prize for physics was split two ways, but both halves went for discoveries beyond Earth. One was for a finding that is, by astronomical standards, quite close by—a planet going ...
