How the Neutrino’s Tiny Mass Could Help Solve Big Mysteries
The KATRIN experiment is closing in on the mass of the neutrino, which could point to new laws of particle physics and reshape theories of cosmology. Of all the known...
Physicists Argue That Black Holes From the Big Bang Could Be the Dark Matter
...come back to life. In one of the latest, published last week in the Journal of Cosmology and Astroparticle Physics, Karsten Jedamzik, a cosmologist at the University of Montpellier, showed...
Why an Old Theory of Everything Is Gaining New Life
...description — the Standard Model of particle physics — constitutes physicists’ best current explanation for everything. It’s neat and it’s simple, but no one is entirely happy with it. What...
Mathematicians Attempt to Glimpse Past the Big Bang
...Jerome Quintin of the University of Waterloo. The trio recently published a paper in the Journal of High Energy Physics in which, Ling said, “we mathematically showed that there might...
Imaginary Numbers May Be Essential for Describing Reality
...predict the outcome of a famous quantum physics experiment known as the Bell test. The new research, which was posted on the scientific preprint server arxiv.org in January, finds that...
The Quest to Quantify Quantumness
...Landau Institute for Theoretical Physics in Russia, and Alexei Kitaev of the California Institute of Technology worked out two schemes for pulling off any quantum calculation: You could include T...
How (Relatively) Simple Symmetries Underlie Our Expanding Universe
Although Einstein’s theory of space-time seems more complicated than Newtonian physics, it greatly simplified the mathematical description of the universe. Isaac Newton and other premodern physicists saw space and time...
Math Proof Draws New Boundaries Around Black Hole Formation
...density approaches infinity and known physics goes off the rails. In the 100-plus years since, physicists and mathematicians have explored the properties of these enigmatic objects from the perspective of...
How the Bits of Quantum Gravity Can Buzz
...Wilczek and Zahariade’s calculation is built on physics that few would disagree with. “We did a very conservative calculation, which is almost certainly correct,” said Parikh. “It essentially just assumes...
