A new theory suggests the universe’s greatest secrets are hiding in a “zeptouniverse” that’s ready to be explored—without ...

A physicist proposes that the universe is not empty space, but is a viscous fluid, fueling the expansion and contraction we see.

New data from major dark-energy observatories suggest the universe may not expand forever after all. A Cornell physicist calculates that the cosmos is heading toward a dramatic reversal: after ...

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 ...

If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

Something genuinely strange has just happened in fundamental physics: an underground neutrino telescope in the Mediterranean recorded an ultra‑energetic particle that current models struggle to ...

Neutrino particles have extremely small masses, yet there are so many of them that they carve out the large-scale structure ...

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 ...

Physicists have been puzzling over conflicting observational results pertaining to the accelerating expansion rate of our Universe—a major discovery recognized by the 2011 Nobel Prize in Physics. New ...

Brown University physics Prof. Stephon Alexander spoke on how the analysis of musical elements can help astrophysicists understand patterns of the universe in his lecture “The Jazz of Physics” ...

Using a quasar located 12.3 billion light-years away as a beacon, a team of astronomers detected the presence of molecular hydrogen in the farthest system ever, an otherwise invisible galaxy that we ...
