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,...
The Mathematical Structure of Particle Collisions Comes Into View
...Their method may help bring about new levels of predictive accuracy, which theorists desperately need if they are to move beyond the leading but incomplete model of particle physics. “They...
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...
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...
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...
How Space and Time Could Be a Quantum Error-Correcting Code
...conjectured in the Journal of High Energy Physics that space-time itself is a code — in anti-de Sitter (AdS) universes, at least. The paper has triggered a wave of activity...
New Black Hole Math Closes Cosmic Blind Spot
...weigh more than 10 solar masses. Earlier this year, researchers at the Max Planck Institute for Gravitational Physics used Field and Khanna’s surrogate model to look through LIGO data for...
Cosmic Triangles Open a Window to the Origin of Time
...the final answer without ever working through the complicated particle dynamics. The results hinted that the usual picture of particle physics, in which particles move and interact in space and...
