A new theory suggests fusion reactors could help scientists search for axions, mysterious particles that may explain dark ...

One of the biggest mysteries of the universe is why its expansion seems to be speeding up. Physicists have attributed it to a strange force called dark energy, but exactly how it works is largely ...

Try as they might, scientists can’t truly rid a space or an object of its energy. But what “zero-point energy” really means ...

Scientists have identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. NASA's Parker Solar Probe is venturing closer to the ...

For decades, scientists have been trying to solve a vexing problem about the weather in outer space: At unpredictable times, high-energy particles bombard the earth and objects outside the earth’s ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Deep underground in Europe, the world's most powerful particle ...

It might be true that there's an ultimate speed limit to everything in the Universe — the speed of light in a vacuum — but that doesn't mean there's a limit to how energetic a single particle can be.

Ultrahigh-energy cosmic rays twist and turn on their way to Earth, which has made it nearly impossible to identify the colossal monsters that create them. In the 1930s, the French physicist Pierre ...
