Relationism is the idea that objects, entities and reality itself is defined and created by interactions and relationships. I will argue that relations aid in the understanding of spacetime for a ...

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 ...

Loop Quantum Cosmology (LQC) applies the non-perturbative techniques of loop quantum gravity to homogeneous cosmological models, yielding a quantum replacement of the classical big-bang singularity by ...

CHAPTERS: 0:00 - Deterministic to probabilistic universe 1:55 - Why must we quantize gravity? 6:22 - What is the central ...

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 ...

In a continuous pursuit to understand the fundamental laws that govern the universe, researchers have ventured deep into the realms of string theory, loop quantum gravity, and quantum geometry. These ...

Physicists have long struggled with their goal of making gravity a quantum force. A radical post-quantum approach might solve ...

Researchers suggest that unambiguous signals of quantum gravity could appear in future tabletop experiments with gravitationally interacting objects. Is gravity quantum or classical? This fundamental ...

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

Physicists have tested the hypothesis that gravitational fluctuations in space-time can destroy quantum superposition and explain why large objects do not behave like particles. An experiment in the ...

In a bold step toward solving one of science's most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...
