If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...

Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

Earth’s magnetosphere, once thought to have a simple electric polarity pattern, has revealed a surprising twist. New satellite data and advanced simulations show that the morning side of the ...

NASA scientists have discovered a third global energy field around Earth. Known as the ambipolar electric field, this force drives charged particles into space above the poles. Two major global energy ...

A strange electric field around the Earth, long suspected to exist, has been detected for the very first time, and it is believed to cause a polar wind which launches particles into space at ...

To put one of physicists’ most important theories to the test, scientists go to extremes. Extremely strong electromagnetic fields, that is. The theory of quantum electrodynamics, which describes ...
