The astrophysicist Joshua Frieman seeks to pinpoint the mysterious substance driving the accelerating expansion of the universe.
Newly discovered particles are forcing physicists to extend their simple picture of subatomic interactions or replace it with a more nuanced understanding.
Physicists have begun to explore the idea that mass and length may not be fundamental properties of nature. The hypothesis could help to avoid the conclusion that our world is just a weird bubble in an endlessly foaming multiverse.
Martin Hairer was named a 2014 Fields medalist for an epic masterpiece in stochastic analysis that colleagues say “created a whole world.”
Katherine Freese, a physicist who will soon lead the Nordic Institute for Theoretical Physics, reflects on the hunt for dark matter and how dark matter heating may have produced the first stars.
Newly discovered patterns in evolution may help scientists make accurate short-term predictions.
The cosmologist David Spergel explains why a widely publicized gravitational-wave discovery could be wrong, and how the “overreaching” study could affect the public’s perception of science.
Chao-Lin Kuo, who helped design the experiment that claimed to have found evidence of gravitational waves from the Big Bang, isn’t bothered by criticism that cosmic dust may account for his results.
Surprising oil drop experiments suggest that the quantum world may not be as strange as advertised.
