For a quarter century, cosmology has rested on a simple but audacious idea: that a fixed “cosmological constant” drives the ...

DESI has made the largest 3D map of our universe. The Earth is at the central vertex, and every dot is a galaxy. DESI collaboration and KPNO/NOIRLab/NSF/AURA/R ...

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

The clearest pictures yet of the newborn cosmos strengthen the prevailing model of the universe but deepen a mystery about its expansion rate. Measurements of this rate, known as the Hubble constant, ...

The accelerated expansion of the present universe, believed to be driven by a mysterious dark energy, is one of the greatest puzzles in our understanding of the cosmos. The standard model of cosmology ...

A survey of more than 25 million galaxies has found a strange contradiction in how astronomers measure the universe's clumpiness, and it could threaten the standard model of cosmology, which describes ...

Scientists from the University of Sheffield suggest that dark matter and neutrinos may interact, challenging existing ...

Right now, it looks like cosmology is at a tipping point. Will the James Webb telescope resolve the issue by revealing new physics? When you purchase through links on our site, we may earn an ...
