Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in ...

Physicists are exploring whether hidden dimensions and the shape of space could help explain why fundamental particles have ...

A team of physicists has coaxed a single, photon-like particle into behaving as if it lives in 37 different quantum ...

At the smallest scales, heat engines can do more than Carnot ever imagined. Researchers at the University of Stuttgart have ...

The masses of fundamental particles such as the Z and W bosons could have arisen from the twisted geometry of hidden ...

Our universe may be hiding extra dimensions just beyond the reach of current experiments — and they could be the key to unlocking two of the most stubborn mysteries in physics. A new theoretical study ...

For the first time, physicists have built a two-dimensional experimental system that allows them to study the physical properties of materials theorized to exist only in four-dimensional space. An ...

Researchers attempting to solve the problem of dark matter have proposed a particle that can travel to an unseen fifth dimension. The work is entirely hypothetical, as it attempts to explain a type of ...

The geometry of space, where physical laws unfold, may also hold answers to some of the deepest questions in fundamental physics. The very structure of spacetime might underlie every interaction in ...
