Although no axion signal was observed, researchers say the system demonstrated stable operation, tunability, and the ability ...

Physicists have started to treat a once-fringe idea with surprising seriousness: that our entire observable universe might be ...

Physicists from around the country converged at UC Santa Barbara for two days of talks and camaraderie in memory of esteemed physicist Professor Jim Hartle, one of four cofounders of the campus’s ...

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

Quantum cosmology and loop quantum gravity constitute two intertwined pillars in the quest for a quantum theory of gravity. Quantum cosmology applies the principles of quantum mechanics to the entire ...

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 lithium problem poses challenges to BBN models, sparking research into cosmic processes and enhancing our grasp of nuclear and astrophysical phenomena.

Welcome to Source Notes, a Future Tense column about the internet’s information ecosystem. At first glance, the video seems like an ordinary news recap. “So today the Nobel Prize in Physics was ...

Where did the universe come from? Where is it headed? Answering these ­questions requires that we understand physics on two vastly different scales: the cosmological, referring to the realm of galaxy ...
