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.

Using the James Webb Space Telescope, scientists have charted billions of years of galactic evolution, and found that ...

A colossal structure in the distant Universe is defying our understanding of how the Universe evolved. In light that has traveled for 6.9 billion years to reach us, astronomers have found a giant, ...

This article was originally published at The Conversation. The publication contributed the article to Space.com's Expert Voices: Op-Ed & Insights. About a century ago, scientists were struggling to ...

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 ...

Unfortunately, any work you do in the universe will have to be done the old-fashioned way. There may be an infinite amount of energy locked in the vacuum of space-time. So could we ever harness this ...

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 ...

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 ...

The space-based observatory will scan the cosmos in 102 colors we can't see to unlock the secret history of the universe. Reading time: Reading time 2 minutes NASA’s newest eye on the cosmos is ...

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, ...
