“Using newer mathematical tools, my colleague and I have demonstrated a new theory that may accurately describe the universe. Instead of basing the theory on the warping of space and time, we ...

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time—the interwoven fabric ...

In 1916, Albert Einstein discovered that his theory of general relativity predicted the existence of gravitational waves — ...

Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe.

Rewinding the Laws of Time and Space. Chronicle photo illustration by Rick Nobles Roni Harnik is an explorer who likes to think big. Foreign continents hold no sway over him.

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 ...

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.

As it studies cosmic microwaves, the Simons Observatory in Chile aims to help prove or disprove cosmic inflation, a notion that the universe expanded rapidly in the moment after the Big Bang.

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy.

Whether space and time are part of the universe or they emerge from quantum entanglement is one of the biggest questions in physics. And we are getting close to the truth By Michael Brooks 25 June ...

Bizarre quantum bonds connect distinct moments in time, suggesting that quantum links—not space-time—constitute the fundamental structure of the universe.
