Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

The force we experience most intimately remains the most mysterious. Physicists understand how vast migrations of particles called photons light up our homes, and how swarms of “gluon” particles hold ...

Physicists have developed a novel approach to solving one of the most persistent problems in theoretical physics: uniting gravity with the quantum world. In a recent paper published in the journal ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...

Quantum gravity seeks a consistent framework to merge the principles of quantum mechanics with general relativity, addressing the challenges of formulating a quantum field theory for the gravitational ...

The biggest open problem in the foundations of physics is that Einstein’s theory of gravity, General Relativity, does not ...

Entropy. The word itself should cause insomnia. It means that matter and energy will degrade—ultimately leading to chaos in the universe—if things are left alone. So why is a new theory suggesting ...

A "New Theory of Everything" aims to advance and improve our understanding of gravity beyond what we know from Einstein's Theory of Relativity. For years, scientists have tried to combine gravity with ...

A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...
