Our best models of the cosmos don't add up — but that could change if the universe is actually made of a viscous 'fluid,' a ...

The expansion of the universe could be a mirage, a potentially controversial new study suggests. This rethinking of the cosmos also suggests solutions for the puzzles of dark energy and dark matter, ...

The universe isn’t just growing—it’s speeding up as it does. That discovery stunned scientists, upending long-held ideas about gravity and motion in space. This rapid expansion wasn’t predicted by ...

The Nature Index 2024 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Our vast universe might not be infinitely expanding after all ...

Churning nano-wormholes could explain the clash in our cosmological constants. The wormholes add magnitude to a math parameter called the Gauss-Bonnet term. Boosting one term in a complex equation ...

Astronomers have known for decades that the universe is expanding. When they use telescopes to observe faraway galaxies, they see that these galaxies are moving away from Earth. To astronomers, the ...

Everything in the universe has gravity – and feels it too. Yet this most common of all fundamental forces is also the one that presents the biggest challenges to physicists. Albert Einstein’s theory ...

New research looking at the cosmological constant problem suggests the expansion of the universe could be an illusion. When you purchase through links on our site, we may earn an affiliate commission.
