It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation ...

The gauge bosons of the standard model of particle physics are responsible for three of the four known forces in the universe, conveyed through the exchange of virtual bosons. In electromagnetism, the ...

A new study reveals that some proposed signatures of quantum gravity may have an unexpected classical explanation.

Scientists have uncovered a surprising connection between quantum gravity and an exotic quantum state of matter that could explain why the universe isn’t expanding wildly fast. The study suggests that ...

(via PBS Space Time) To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity. And to do that, most physicists believe we need a ...

One of the deepest ambitions in modern physics is understanding how the fabric of space and time could emerge from fundamental quantum degrees of freedom to establish a quantum theory of gravity.

Quantum gravity seeks to reconcile the principles of quantum mechanics with the geometric framework of general relativity, aiming to describe spacetime at the Planck scale. Within this endeavour, ...

A series of theoretical results from some of the field’s most prominent physicists now supports a striking idea: quantum entanglement between particles may not be severed when one of them crosses a ...

Quantum gravity seeks a unified framework reconciling general relativity’s description of spacetime with quantum mechanics. Leading approaches include loop quantum gravity, spin-foam models and group ...

Gravitons, the particle of quantum gravity, may be impossible to detect. To progress to the next level in understanding reality, we need to combine quantum mechanics and Einstein’s general relativity.
