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 ...

We often marvel at the genius of Albert Einstein, a physicist who revolutionized our understanding of the universe. Yet, even ...

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.

Teleology is the idea that some processes in nature are directed toward a goal or an end. Today, it is commonly asserted that teleology is a remnant of antiquated ways of thinking about causation, and ...

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 ...

The third Quantum Gravity conference took place at Penn State University from 21 to 25 July 2025, bringing together ...

The dream of time travel has fueled stories, films, and scientific debates for generations. The idea that you could step into a machine and reappear in another era has captivated people for as long as ...

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 ...

Synthese, Vol. 197, No. 5, Special Issue on New Trends in the Metaphysics of Science (May 2020), pp. 1961-1982 (22 pages) In this paper, I will argue that metaphysicians ought to utilize quantum ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...
