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 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...
How Radio Astronomy Reveals the Universe
Radio waves, longer and less energetic than visible light, give astronomers access to some of the most obscure physics in the cosmos. If you ask an astronomer to choose the...
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...
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...
What Can Jellyfish Teach Us About Fluid Dynamics?
...physics. And so there was a movement that emerged, now a couple of decades ago, to say: Why don’t we study some animal systems that have already figured it out,...
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,...
Virginia Trimble Has Seen the Stars
...on to become one of the first women to earn a doctorate in astrophysics at the California Institute of Technology. While she was there, she befriended Richard Feynman, who paid...
How (Nearly) Nothing Might Solve Cosmology’s Biggest Questions
...the gravitational pull of the structures defining a void’s edge. Because of this, in a void “very little happens,” Pisani said. “There are no mergers, no complicated astrophysics. This makes...
