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 ...

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe ...

How did the universe start? Did we begin with a big bang, or was there a bounce? Might the cosmos evolve in a cycle of expansion and collapse, over and over for all eternity? Now, in two papers, ...

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, ...

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 ...

Ars Technica has been separating the signal from the noise for over 25 years. With our unique combination of technical savvy and wide-ranging interest in the technological arts and sciences, Ars is ...
