In the moments before the Big Bang, our universe was a hot, dense, and extremely high-energy place. That all changed when the universe exploded 13.8 billion years ago. Rapid inflation divided a ...

"This may be reshaping how we think about the Universe, and it's exciting! There are still surprises left in cosmology, and who knows what discoveries will come next?" This research was published in ...

Particle physics is the study of the elementary building blocks of matter and radiation and their interaction. The fundamental particles are summarised by the standard model. This includes leptons ...

New research suggests that dark energy isn't needed to explain the acceleration in the expansion of the universe — instead suggesting giant voids in space are creating an illusion. When you ...

What is the structure of our physical reality? Physicists have long imagined space and time interweaving into “space-time”, the metaphorical fabric that underlies the cosmos. But there may be ...

This discovery resolved the debate: the spiral nebulae were not mere clouds but entire galaxies. Hubble’s finding fundamentally altered humanity’s understanding of the cosmos, revealing a universe far ...

Dark matter can't be too heavy or it might break our best model of the universe, new research suggests ... extensions of the Standard Model of particle physics predicted the existence of such ...

Extremely precise measurements of the distance between the Earth and the Coma cluster of galaxies provide new evidence for the Universe’s faster-than-expected rate of expansion. (Photo courtesy ...

The Hubble tension grows: new data shows the Universe’s expansion defies current physics models, suggesting our understanding of cosmology may need a major overhaul. Credit: SciTechDaily.com New ...

DURHAM, N.C. — Our cosmic neighborhood is revealing an uncomfortable and unexplainable truth: the universe seems to be breaking the speed limit set by our best physics models. By precisely measuring ...
