At the core of modern physics lie these two fundamental pillars: quantum theory, governing the behavior of the tiniest particles, and Einstein's ...

Gravity may be created by strange flashes in the quantum realm

HOW do you reconcile the two pillars of modern physics: quantum theory and gravity? One or both will have to give way. A new approach says ...

Does quantum theory imply the entire Universe is preordained?

This idea reached its peak with the strict, precise laws about how the Universe behaves introduced by classical physics. Take Isaac Newton's ...

Why Achieving a Grand Unified Theory in Physics Remains a ...

Quantum gravity seeks to describe the gravitational force in terms of quantum field theory, but a complete and consistent theory has remained ...

How can gravity and quantum coexist in the same theory?

In a theory that unifies quantum mechanics and gravity, spacetime and the wave function should be placed on the 7-sphere. Cite.
