Images made with the W.M. Keck Observatory in Hawaii show how light from two distant galaxies is distorted into multiple images. UC Davis astronomers have made a new estimate of the Hubble Constant, ...

Learn how to calculate a satellite’s momentum and position under a constant force! 🛰️📐 This physics tutorial explains step by step how to model motion, apply Newton’s laws, and analyze orbital ...

Planck's constant reveals the quantum world's fundamental energy levels. It shows how light and matter exist in discrete units (quanta). This constant defines limits to our knowledge of particle ...

Electronics is really an applied branch of physics, so it isn’t surprising that if you are serious about your electronics, you probably know a little physics, too. If you’ve ever heard the term “fine ...

SANTA BARBARA, Calif. — The word “crisis” hung in the air from the very beginning of the meeting. In a room just steps from the ocean in Santa Barbara, astronomers and physicists shifted restlessly in ...

A team in Paris has made the most precise measurement yet of the fine-structure constant, killing hopes for a new force of nature. As fundamental constants go, the speed of light, c, enjoys all the ...

At a fundamental level, our Universe is made of particles, forces, interactions, and the fabric of space and time. Spacetime forms the ever-evolving stage on which the play of the cosmos unfolds, ...
