Quantum mechanics and general relativity are the two pinnacles of 20th-century physics. In their respective fields, ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

For more than a century, physicists have been trying to reconcile the smooth geometry of gravity with the jittery ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

There are more and more instances popping up where AI systems are helping science and math researchers with their research. A Michigan ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

"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 ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...
