The Case Against Dark Matter
...he says it’s too soon to tell whether everything in the paper — which draws from quantum information theory, thermodynamics, condensed matter physics, holography and astrophysics — hangs together. Either...
New Proof Distinguishes Mysterious and Powerful ‘Modular Forms’
Using “refreshingly old” tools, mathematicians resolved a 50-year-old conjecture about how to categorize important functions called modular forms, with consequences for number theory and theoretical physics. In a new proof,...
Physicists Study How Universes Might Bubble Up and Collide
...“Because it’s an experiment, it contains by definition all the physics that nature wants to put in it including quantum effects and classical effects,” Peiris said. Peiris leads a team...
Asymmetry Detected in the Distribution of Galaxies
...a cherished symmetry of physics. But then, in 1957, the Chinese American physicist Chien-Shiung Wu’s nuclear decay experiments revealed that our universe indeed has a slight handedness to it: Subatomic...
The Materials Scientist Who Studies the Innards of Exoplanets
...a laboratory for mineralogy and high-pressure physics, and that’s basically how I started working in high-pressure physics. What sparked your attraction to it? In everyday life, you experience the changes...
In Search of Cracks in Albert Einstein’s Theory of Gravity
...and the United Kingdom; then, at 29, she was invited back to Mexico to run the theoretical physics department of the Mesoamerican Center for Theoretical Physics. A few years later,...
Troubled Times for Alternatives to Einstein’s Theory of Gravity
...September 2017, he was at the Institute for Theoretical Physics in Saclay, near Paris, to speak at a meeting about dark energy and modified gravity. The official news had not...
The Universe Is Not a Simulation, but We Can Now Simulate It
...a different approach to this abridgement, picking and programming what they saw as the key astrophysics. Then, in 2012, a study by Cecilia Scannapieco of the Leibniz Institute for Astrophysics...
The Strange Numbers That Birthed Modern Algebra
The 19th-century discovery of numbers called “quaternions” gave mathematicians a way to describe rotations in space, forever changing physics and math. Imagine winding the hour hand of a clock back...
