Scientists say it's possible to use tiny ripples in space and time, or gravitational waves, to measure the rate at which our ...

Quasicrystals are orderly structures that never repeat. Scientists just showed they can exist in space and time.

The shape of the cosmos depends on a balance of two competing forces: the pull of gravity and the expansion driven by dark ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

For the last 25 years, most scientists have believed that about 70% of the universe is formed by something called ‘’dark ...

The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

A new hypothesis known as the Quantum Memory Matrix (QMM) could help explain some of the biggest mysteries of the universe, including the Black Hole Information Paradox. The idea is that space-time ...

An astrophysicist explains what wormholes are and how these theoretical space-time tunnels have popped up in the solutions to a set of decadesold equations.

Wormholes are often imagined as tunnels through space or time — shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In ...
