Virtual particles may not be real, but they help physicists track how forces move, and allow for incredibly precise ...

A round of applause, please: Scientists have finally figured out what’s behind the sound of clapping. The research pinpoints a mechanism called a Helmholtz resonator — the same acoustic concept that ...

String theory is one of the most ambitious ideas in modern physics, aiming to unite all forces of nature into one framework.

A recent paper has proposed a new idea for what is causing the observed accelerated expansion of the universe, and dark ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the ...

Do kaons decay using a new kind of physics? Researchers are trying to explain their anomalous findings. Their larger experiment is an ongoing investigation of CP symmetry. The anomalies could be ...
