E = mc² is a simplified form of the more complete equation E² = (mc²)² + (pc)², where the term 'pc' accounts for kinetic energy. The equation E = mc² accurately reflects the relationship between ...

Researchers propose a new theory for the origin of dark matter, the invisible substance thought to give the universe its shape and structure. Their mathematical models show that dark matter could have ...

For more than a century, physics has been built on two great theories. Einstein's general relativity explains gravity as the bending of space and time. Quantum mechanics governs the world of particles ...

Data from an African observatory show that jets from a collapsed star are capable of producing some of the Galaxy’s fastest particles. An array of telescopes in Namibia has pinpointed the origin of ...
