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

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

Scientists are a step closer to solving one of the universe's biggest mysteries as new research finds evidence that two of ...

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 ...

New research suggests the universe may be lopsided. Cosmic microwave background and galaxy data hint at directional differences, challenging cosmology’s assumption of uniformity and standard ...

What are the mysterious dark matter and dark energy that seem to account for so much of our universe? Why is the universe expanding? For the past 30 years, most cosmologists have looked to the ...

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, ...

Mr. Sundman earned a Masters of Science degree through the Department of Engineering Physics at Helsinki University of Technology. There, Stig became interested in elementary particle physics, with ...
