Surprisingly, there are ways to peer into hidden dimensions without having to access them directly. Imagine rolling up a tube ...

A new study casts doubt on the universe’s accelerating expansion, suggesting dark energy might be weakening over time.

Physicists have determined that most of the universe is dark matter -- invisible to us but affecting the universe anyway.

If so, laws might change when the universe itself changes phase. In the early universe, as temperatures and densities shifted, forces split apart from a unified origin. What we call “laws” may be like ...

Researchers from around the world have sought to answer important questions about the most basic laws of physics that govern our universe. Their experiment, the Majorana Demonstrator, has helped to ...

An artist’s impression of the cosmic web. Shown as a vast cobweb-like structure of mostly purple and some orange filaments on a black background, the web is the soap-sud structure of the universe ...

Yet according to physics, information is never destroyed. In principle, a burned book is just as readable as the original—if ...

Deep in the heart of the matter, some numbers don't add up. For example, while protons and neutrons are made of quarks, ...

Fundamental questions that particle physicists have pondered for decades might be answered when a $9.2 million neutron physics beam line is built at the Department of Energy’s Spallation Neutron ...
