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 ...

By stopping black holes from fully evaporating, hidden dimensions may solve a cosmological paradox.

One of the best-performing models in cosmology is also one with the least physical rationale behind it. Columnist Leah Crane ...

In a new paper, physicists argue that hypothetical particles called axions could explain why the universe isn’t empty. Physicists have long hypothesized the existence of a minuscule particle called ...

A recent study has made strides toward solving one of physics’ biggest puzzles: including all known particles and interactions into the theory of quantum gravity. The solution is to modify the quantum ...

Google updated its search engine and Lens tool with new features to help you visualize and solve problems in more difficult subjects like geometry, physics, trigonometry and calculus. The update ...
