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 ...

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 ...

For centuries, humans have looked to the stars and wondered about the universe’s vastness, shape, and structure. One question that has long persisted is the concept of the center of the universe. Is ...

"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 ...

"If such a fifth force exists, it cannot exceed 7% of the strength of gravity." Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological ...

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 ...

Here’s what you’ll learn in this story: Time might actually have 3 dimensions. But it also means that the space would actually be one-dimensional, instead of the three dimensions we’re familiar with.

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 ...
