The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Scientists have determined a way to measure gravity on microscopic levels, perhaps bringing them closer to forming a theory of "quantum gravity" and to solving some major cosmic mysteries. Quantum ...

(via PBS Space Time) Black holes are inevitable predictions of general relativity—our best theory of space, time and gravity. But they clash in multiple ways with quantum mechanics, our equally ...

The evolution of quantum mechanics has continuously deepened our understanding of the microcosm, guiding researchers from the seminal formulation of the Schrödinger equation to more refined ...

A null boundary carries a degenerate signature (0++) metric, which is obtained by taking the pull-back of the four-dimensional line element to the boundary. Credit: Classical and Quantum Gravity (2025 ...

Relativistic quantum mechanics, traditionally governed by the Dirac equation, has been continually refined to better encapsulate the interplay between quantum systems and gravitational fields. This ...

Breakthroughs in science often begin with a simple question and years of tireless exploration. From the way tiny molecules slip through microscopic pores to the staggering behavior of matter near ...

Quantum entanglement, a bewildering phenomenon where particles become interconnected regardless of the distance separating them, challenges our fundamental understanding of reality. It has puzzled ...
