"A quantum theory of gravity is needed to understand what kind of phenomena there are in cases where there's a gravitational field and high energies," says Partanen.

Bianconi’s work extends this thermodynamic analogy, employing quantum relative entropy to bridge the gap between quantum field theory and general relativity.

Therefore, quantum theory could not provide the ultimate description of the world. Albert Einstein’s contributions to the field of quantum mechanics are under-appreciated, says Aspect.

"If this turns out to lead to a complete quantum field theory of gravity, then eventually it will give answers to the very difficult problems of understanding singularities in black holes and the ...

Why Gravity Resists Unification The Standard Model is built on a framework called quantum field theory. This theory merges classical field theory, quantum mechanics, and special relativity.

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.

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests.

Gravity as Quantum Entropy Gravity, traditionally seen as the curvature of spacetime caused by massive objects, might instead arise from entropy—a measure of disorder. This new theory treats ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved ...
