Using gravitational waves as a measure of the universe's rate of expansion could solve the biggest headache in physics, the ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. Thanks to a global network of observatories—called the Laser Interferometer Gravitational-Wave ...

When black holes collide, the crash generates ripples in the fabric of spacetime—gravitational waves. These distortions ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

For the past two decades, scientists have wondered about a bright, distinct striped pattern seen in radio waves emanating ...

What was your favorite toy growing up? This paradox claims that memory—and every other one—is just a random fluctuation.

The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a black hole.

Astronomers have long known the universe is expanding—but exactly how fast remains one of the biggest mysteries in cosmology. Different techniques for measuring the Hubble constant stubbornly disagree ...

There was a time before portable TVs and personal media players when the idea of putting coin-operated TVs everywhere, from ...

Scientists propose a gravitational-wave method called the stochastic standard siren to measure the Hubble constant, offering an independent way to examine the universe’s expansion and the Hubble ...
