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.

Textbooks give strange, imprecise explanations of where things happen in quantum mechanics. Consistency with gravity needs a fresh approach.

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...

Quantum physics is often described as the most successful scientific framework in history. In its 100 years of existence, it has explained everything from the periodic table of the elements to how ...

Abstract: Black holes are often portrayed as cosmic vacuum cleaners that swallow everything, even light. In reality, they are far richer and more revealing: each black hole is a natural laboratory ...

There is no question that quantum theory is correct. It’s been proven over and over, both in the lab and through practical achievement. But the question remains: is it always correct? Quantum ...

"This work is a step toward understanding how quantum mechanics and gravity work together, a major unsolved problem in physics." The first step toward quantum gravity, the "holy grail of physics," may ...
