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, ...

"We will push the limits of what we can observe, and use every gravitational lens we detect with Roman to pin down the particle nature of dark matter." When NASA’s Nancy Grace Roman Space Telescope ...

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

The fabric of space and time is not exempt from the effects of gravity. Plop in a mass and space-time curves around it, not dissimilar to what happens when you put a bowling ball on a trampoline. This ...

The current "standard model" of the cosmos, its history, and its evolution is called the Lambda Cold Dark Matter (LCDM) model — but the supremacy of this model, in which lambda represents the ...

A new paper suggests that we may be able to spot alien spaceships hopping between distant stars using "warp drives" because the sci-fi-inspired technology would give off specific gravitational waves ...

Scientists have calculated the speed of a spinning supermassive black hole by studying the 'spaghettified' remains of a star it destroyed. When you purchase through links on our site, we may earn an ...

In the realm of physics, the speed of light is considered one of the most fundamental constants in the universe, dictating the structure of time and space as we know it. But what if this cornerstone ...

As the digital age has advanced, satellites have become indispensable pillars of our modern world that orchestrate navigation, communication and commerce. But these serene celestial sentinels face a ...

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 ...
