Nuclear fusion, the process that powers every star in the observable universe, has moved from theoretical physics into the realm of real laboratory results. On December 5, 2022, scientists achieved ...

The total energy of the ball consists of its potential energy (related to position) plus its kinetic energy (related to motion). To zero out both components, you would have to give a precise value to ...

Precious metals may be escaping from the planet’s core. This hotly debated subject could help us understand Earth’s evolution and determine whether life exists elsewhere in the Universe ...

Astronaut Shubhanshu Shukla has used a water blob to explain Earth's shape. Discover the physics of surface tension, rotation, and inertia in this space and physics explainer.

Scientists now understand why seismic waves speed up near Earth's core. Extreme pressure and temperature cause solid mantle rock to flow slowly, aligning mineral crystals. This anisotropic structure ...

It's well established that the universe is expanding, but there's serious disagreement among scientists over how fast it's ...

At the smallest scales of matter, nature behaves in ways that feel almost counterintuitive. Individual particles follow simple rules, but when they interact together, entirely new behaviors can ...

John Friedrich led a high-profile land and sea rescue squad, but as Marc Fennell reveals, it was all built on lies ...
