If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

A new recipe for black holes could do away with central singularities, saving the laws of physics from troubling infinities.

While quantum mechanics governs the behavior of particles at the smallest scales, general relativity describes the force of gravity on cosmic scales. Unifying these two frameworks has been one of the ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of ...

This theory tries to reconcile Einstein’s theory of general relativity (which sees gravity as a warping of spacetime) with quantum theory (which views the universe as being made of extremely ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) is ...

underpinning these theories is Einstein’s general theory of relativity, which treats space and time as a unified “spacetime” and considers gravity as spacetime’s curvature. Perhaps ...

Scientists propose a relatively simple yet still complicated tabletop experiment to test the quantumness of gravity, aiming to reconcile general relativity and quantum mechanics.

While quantum mechanics governs the behavior of particles at the smallest scales, general relativity describes the force of gravity on cosmic scales. Unifying these two frameworks has been one of ...

Since the beginning of the 20th century, Einstein's theory of general relativity has been the best description we have of how gravity works. However, right around when Einstein came up with ...
