Quantum gravity and field theory represent a frontier where the principles of quantum mechanics are reconciled with Einstein’s description of gravity. Researchers are seeking a consistent framework ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other ...

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 understanding ...

While this may complicate the quest for a clear experimental signature of quantum gravity, it does not render such tests useless. According to the research team, both classical and quantum models of ...

A theoretical study suggests that gravity could have quantum effects without itself being a quantum theory. Other researchers ...

Dr. Jens Eisert, Department of Physics, Dahlem Center for Complex Quantum Systems, Freie Universität Berlin, Email: ...

Quantum gravity remains one of the big missing pieces of a Grand Unified Theory that could bridge quantum field theory and general relativity. Knowing that quantum gravity solutions must resemble ...
