A novel theory of 'wavy space-time' suggests that the division between our best descriptions of the universe on its smallest and largest scales may be because gravity does not play by quantum rules.

Few ideas in modern science have reshaped our understanding of reality more profoundly than space-time—the interwoven fabric ...

The Einstein equation of general relativity describes spacetime and gravity, while the rest of physics is described by quantum mechanics and the Schrodinger equation.

One: Gravity is quantum - this means gravity and by extension the fabric of spacetime exhibit the various weird properties of quantum world, like superposition and entanglement.

Einstein’s theory of general relativity, where gravity is caused by the curvature of space-time, is awesome. It has been confirmed to an incredible level of precision, extending to fifteen ...

Could emergent gravity, where it's entropy that's the fundamental quantity in the Universe, revolutionize our understanding of how it all works?

Did space-time emerge from quantum effects? We first discovered the laws of gravity, and then those of quantum mechanics. But new work suggests nature might go about it the other way around: space ...

One of the most robust 1,2 expectations for quantum gravity—the theory describing the interplay between gravity and quantum mechanics—is that space-time itself at the smallest scales should ...
