The geoid (the surface of equal gravitational potential of a hypothetical ocean at rest) serves as the classical reference ...

The total energy of the ball consists of its potential energy (related to position) plus its kinetic energy (related to motion). To zero out both components, you would have to give a precise value to ...

Dark energy is one of those cosmological features that we are still learning about. While we can't see it directly, we can most famously observe its effects on the universe—primarily how it is causing ...

Lasers, devices that emit intense beams of coherent light in specific directions, are widely used in research settings and are central components of various technologies, including optical clocks (i.e ...

He came up with a new one, called the Late-Transition Interacting Thawer (LTIT) model, which models how dark energy could "thaw" after a certain amount of time after the universe started and is slowly ...

Casimir cavities are mysterious spaces between microscopic metal plates in a vacuum. Areas of diminished energy between the ...

Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

Kimberly Boddy, an assistant professor of physics at The University of Texas at Austin, has been named a 2026 Alfred P. Sloan Research Fellow, one of the most competitive honors for early‑career ...

Scientists have used theloudest gravitational wave signal ever recorded to put Albert Einstein’s century-old theory of ...

For decades, scientists have theorized that the Milky Way Galaxy’s supermassive black hole, known as Sagittarius A* (Sgr A*), ...

They show up as a mathematical solution in general relativity, basically as a time-reversed version of a black hole. Some ...

The unveiling by IBM of two new quantum supercomputers and Denmark’s plans to develop ‘the world’s most powerful commercial quantum compute ...
