From the mid-1980s, string theory set up a possible framework to approach quantum gravity using a 'top-down' approach. The effective field theory approach to strong forces drove the development of ...

is a quantum field theory of gravity. Alone of the four forces, gravity has no particles attached to it, and is instead explained by Einstein’s general theory of relativity as the warping of ...

Gravity is the only major force in the universe that doesn’t fit into our current quantum framework, driving the pursuit of a grand unified theory of physics. The new test would not be proof or ...

quantum information theory in quantum field theory and quantum gravity, early-universe cosmology, geophysical fluid dynamics, and physical oceanography.. Associate Professor Brian Swingle's research ...

“String theory was developed for people to understand the physics of the strong interaction. [...] People started from a very simple model where they saw that if you take two quarks (a fundamental ...

Conversely, it means that quantum gravity becomes apparent at energies ... Towards a unified field theory NOVA: If the '60s and '70s constituted the era of particle physics, how will this current ...

String theory ... excitement. Field of dreams In Einstein's day, the strong and weak forces had not yet been discovered, but he found the existence of even two distinct forces—gravity and ...
