For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general ...

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

A team of scientists is proposing a bold alternative to the Big Bang theory, suggesting that our universe may have formed ...

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.

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

What can Earth-sized exoplanets teach scientists about the formation and evolution of exoplanets throughout the cosmos? This is what a study recently posted to the arXiv preprint server hopes to ...

The Vera C. Rubin Observatory released its first images, showcasing millions of galaxies. The images are also expected to reveal thousands of previously unknown space objects. Researchers at UC San ...

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 ...

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

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