For more than a century, physicists have been trying to reconcile the smooth geometry of gravity with the jittery ...

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) ...

A deceptively simple experiment that involves making precise measurements of the time it takes for a particle to go from point A to point B could cause a breakthrough in quantum physics. The findings ...

The prevailing assumption has been that Einstein's theory of gravity must be modified, or 'quantized', in order to fit within quantum theory. This is the approach of two leading candidates for a ...

Quantum theory fails to explain how the reality we experience emerges from the world of particles. A new take on quantum ...

Quantum theory is often sold as a story about tiny particles, but its real disruption lands squarely on our everyday sense of ...

Quantum invariants have emerged as powerful algebraic and numerical tools that encapsulate the subtleties of topological structures. By drawing on quantum group theory and the constructs of ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Every once in a while, a revolutionary idea comes along that has the ...

Quantum mechanics, the theory which rules the microworld of atoms and particles, certainly has the X factor. Unlike many other areas of physics, it is bizarre and counter-intuitive, which makes it ...

Quantum electrodynamics was put to the test with highly charged uranium ions To put one of physicists’ most important theories to the test, scientists go to extremes. Extremely strong electromagnetic ...
