For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

Researchers have discovered a hidden quantum geometry inside materials that subtly steers electrons, echoing how gravity warps light in space. Once thought to exist only on paper, this effect has now ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at once, described by a mathematical object called a wavefunction.

Quantum gravity is a research area in theoretical physics that seeks a consistent, predictive framework unifying general relativity with quantum mechanics by quantizing the gravitational field. It ...

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast ...

Quantum gravity seeks a consistent framework to merge the principles of quantum mechanics with general relativity, addressing the challenges of formulating a quantum field theory for the gravitational ...

Einstein’s theory of general relativity explains that gravity is caused by a curvature of the directions of space and time. The most familiar manifestation of this is the Earth’s gravity, which keeps ...

Recent advances in theoretical physics have increasingly highlighted the pivotal role of algebraic structures in unifying particle physics with quantum gravity. These approaches leverage sophisticated ...

The mystery of dark matter—unseen, pervasive, and essential in standard cosmology—has loomed over physics for decades. In new ...

This talk tells the story of symmetry in theoretical physics, and its interplay with developments in our understanding of gravity over the years. In this talk, McNamara explores the power of symmetry ...

The image depicts an experiment in which heavy particles(illustrated as the moon), cause an interference pattern (a quantum effect), while also bendingspacetime. The ...
