In Fake Universes, Evidence for String Theory
...is a loaded word,” said Mukund Rangamani, a professor at Durham University in the United Kingdom and the co-author of a paper posted recently to the physics preprint site arXiv.org...
Quantum Weirdness Now a Matter of Time
...about quantum physics that goes beyond classical physics to endow particles with this supermemory? Researchers have differing opinions. Some say the key is that quantum measurements inevitably disturb a particle....
The Particle That Broke a Cosmic Speed Limit
...window into the laws of physics at otherwise unreachable scales — maybe even connecting particle physics with the evolution of the cosmos as a whole. At the very least, they...
Quanta Writers and Editors Discuss Trends in Science and Math
...physics. Geometry and topology and physics have been kind of intertwined for several decades, but number theory and physics are really starting to communicate a lot more. This article in...
A New Theory to Explain the Higgs Mass
...gravity is hundreds of millions of trillions of trillions of times weaker than magnetism and the other microscopic forces of nature. This disparity shows up in physics equations as a...
Seeing Time Through a Liquid Crystal Display
Time is one of the most fascinating and mysterious subjects in physics. In June, about 60 experts gathered to discuss the nature of time at the Time in Cosmology conference,...
