For more than a century, gravity has been the stubborn outlier in physics, perfectly described on cosmic scales yet refusing to mesh with the quantum rules that govern everything else. A growing camp ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. An image of a black hole surrounded by matter. Does the secret of quantum gravity lie around ...

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 ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Here’s what you’ll learn in this story. A new paper uses a simplified model to prove that gravity can be unified between quantum and standard physics. The simpler model still meets the established ...

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

If you want to understand gravity, it makes sense to study black holes. Nowhere else can you find so much gravity so conveniently compacted into such a relatively small space. In a way, in fact, black ...

Gravity can turn itself into light, but only if space-time behaves in just the right way, a research team has found. Under normal circumstances, you cannot get something from nothing. Specifically, ...
