Susskind and Friedman follow their collaboration on Quantum Mechanics by probing the mathematical nitty-gritty of field theory and Einstein’s theory of special relativity in the third ...

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

Despite the change, the differences in the photon spheres between classical relativity and the predictions of these exotic models are still too small to be seen with the Event Horizon Telescope.

"Quantum theory and Einstein's theory of general relativity are mathematically incompatible with each other, so it's important to understand how this contradiction is resolved.

Despite the change, the differences in the photon spheres between classical relativity and the predictions of these exotic models are still too small to be seen with the Event Horizon Telescope.

For over a century, Einstein's general relativity has brilliantly described gravity on large scales. Yet it remains incompatible with quantum mechanics, which governs phenomena at the particle scale.
