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

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 ...

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, ...

Mikhail Ivanov, Oliver Philcox, and Marko Simonović won the New Horizons Award for their work on large scale structures — the strands and filaments of our universe which contain buried clues to its ...

No one knows for sure, but it is not unlikely that the universe is constructed in a completely different way than the usual theories and models of today predict. The most widely used model today ...

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 ...

What if the bridge between our worlds isn’t language at all, but physics? In a recent episode of SETI Live, theoretical physicist Dr. Daniel Whiteson, co-author of Do Aliens Speak Physics?: And Other ...

I think my favorite line in Tony Kushner's theatrical masterpiece, Angels in America, is "In this world, there is a kind of painful progress." It somehow encapsulates, in just 10 words, the odyssey of ...

Over geological time, information loss is the norm, not the exception. The “unitarity” principle of quantum mechanics says ...
