"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in ...

What we saw in the DESI experiments, and now strengthened by our South Pole Telescope observations, is that dark energy is ...

Scientists are encouraged to use accessible language and engage with the public to demonstrate the relevance of science to ...

Three intertwined time directions may underpin everything, turning space into mere “paint on the canvas” and pushing physics ...

Is the Hubble constant—a key part of how we measure the expansion of our universe—in a crisis? Some cosmologists say yes.

The curious minds at Aperture show how Einstein’s theory of relativity reshaped how we think about time, space, and gravity.

From four-dimensional hexagons to the mind-bending amplituhedron, geometrical shapes are wilder than we learn at school - and ...

A festinating new theory shifts focus from space to time, arguing the clock-ticking we take for granted is richer and weirder ...

Disk galaxies, like our own Milky Way galaxy, commonly consist of both a thick and thin disk of stars—each with different ...

Compact ruddy galaxies seen by the James Webb telescope confound astronomers. Having very little spin at birth may explain the galaxies’ small sizes.

That is the provocative assertion behind Professor Ginestra Bianconi’s latest work, which reframes gravity as an emergent phenomenon arising from the interplay of spacetime geometry, quantum ...

A trippy fringe theory suggests that time is the source of all physical matter, and space is merely a byproduct.
