A team of physicists have proposed a new idea for uniting quantum mechanics and gravity, which they believe could explain the ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

This video summarizes quantum gravity, highlighting the conflict between general relativity and quantum mechanics. It ...

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

This hybrid platform enables a new class of experiments—ones that could finally let us test whether gravity needs to be described by quantum theory." The new paper demonstrates laser cooling of a ...

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 ...

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 ...
