Quantum mechanics and Einstein’s theory of gravity explain almost everything we see in nature, yet physicists still do not know how to unite them. A new theoretical framework suggests that some ...

The odds of the bet Jonathan Oppenheim made in 2023 are generous, even at 5000 to 1. But if he wins, it could transform our view of the universe. The physicist is wagering that space-time, and ...

Physicists have tested the hypothesis that gravitational fluctuations in space-time can destroy quantum superposition and explain why large objects do not behave like particles. An experiment in the ...

IntroductionIn this series, we are testing the idea that "the universe might be a simulation running on a giant computer" by ...

A team of physicists has uncovered a surprising new way to explore one of science's greatest challenges: uniting the two fundamental theories that explain how our universe works—Einstein's theory of ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Before determining the correct quantum theory of gravity, researchers need to know if gravity is actually quantized. Experiments testing that assumption are now being developed. Quantum fluctuations ...

Researchers suggest that unambiguous signals of quantum gravity could appear in future tabletop experiments with gravitationally interacting objects. Is gravity quantum or classical? This fundamental ...
