The Seek for Darkish Matter Is Dramatically Increasing

https://ift.tt/eA8V8J
Physicists are checking whether or not darkish matter tickles several types of detectors, nudges starlight, warms planetary cores, and even lodges in rocks. Ever since astronomers reached a consensus within the Eighties that many of the mass within the universe is invisible—that “darkish matter” should glue galaxies collectively and gravitationally sculpt the cosmos as an …

Mathematical ‘Hocus-Pocus’ Saved Particle Physics

https://ift.tt/eA8V8J

Renormalization, a technique that helps bridge the big and the small, has become perhaps the single most important advance in theoretical physics in 50 years. In the 1940s, trailblazing physicists stumbled upon the next layer of reality. Particles were out, and fields—expansive, undulating entities that fill space like an ocean—were in. One ripple in a …
