Tiny but ageing neutrinos can be used to test the very foundations of quantum theory at unprecedented cosmological time scales Schrodinger’s skinniest kittens Must the Schrodinger’s Cat be fat enough ...

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 ...

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

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 suggests that the unification between quantum physics and general relativity has eluded scientists for 100 years because huge "fluctuations" in space and time mean that gravity won't play ...

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

Quantum simulation plays an irreplaceable role in diverse fields, beyond the scope of classical computers. In a recent study, Keren Li and an interdisciplinary research team at the Center for Quantum ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. Now, a newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Over a century ago, two theories were put forward to explain all of reality: quantum mechanics and general relativity. Both have been refined and improved over decades and extensively tested. They are ...
