The Big Bang model begins with a point of infinite density where the laws of physics break down. This is a deep theoretical problem that suggests the beginning of the Universe is not fully understood, ...

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 ...

UChicago physics Prof. Bonnie Fleming, who is also the chief research officer at Fermi National Accelerator Laboratory, is ...

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 ...

A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

On January 22, 2025, physicists unveiled a groundbreaking discovery that could revolutionize our understanding of the universe and potentially unlock the secrets of time travel. The existence of ...

Attempts to describe quantum physics are rarely enjoyable, but Paul Davies' zeal in Quantum 2.0 sometimes steers too close to ...

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 ...

This is the light echo of the Big Bang, the first light that freely moved through the universe. This relic is crucial to our ...

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 ...
