After a century of observations spanning the breadth of the cosmos and theoretical insights that push humanity's vision of ...

Massive ripples in the very fabric of space and time wash over Earth constantly, although you'd never notice. An astrophysicist is trying a new search for these gravitational waves. University of ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has driven a hundred-year debate between philosophy and science. In Einstein’s ...

The James Webb Space Telescope (JWST) continues to deliver awe-inspiring views of the cosmos and the art world has taken ...

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you’ll ...

Scientists using NASA's James Webb Space Telescope now think the "little red dots" spotted in the early universe could be a new kind of space object. They call it a "black hole star." - T. Müller / A.

University of Colorado Boulder astrophysicist Jeremy Darling is pursuing a new way of measuring the universe’s gravitational wave background—the constant flow of waves that churn through the cosmos, ...
