The search for quantum gravity is the next big step in physics, as researchers seek to unify the physics of the very small ...

In the strange world of quantum mechanics, nothing isn’t ever actually nothing — and now we have found that nothing, or the absence of a photon, can be used to cool things down. One of the most common ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...
