The glow from faster-than-light particles gives us a unique way to explore the universe. Nothing can travel faster than light — in a vacuum. But when light slows down, sometimes matter can blaze past ...

When it comes to speed limits, the ultimate one set by the laws of physics themselves is the speed of light. As Albert Einstein first realized, everyone looking at a light ray sees that it appears to ...

An innovative algorithm for detecting collisions of high-speed particles within nuclear fusion reactors has been developed, inspired by technologies used to determine whether bullets hit targets in ...

There's an ultimate speed limit in the Universe: the speed of light in a vacuum, c. If you don't have any mass — whether you're a light wave (a photon), a gluon, or even a gravitational wave — that's ...

The origin of the universe's most powerful cosmic rays, or high-speed particles, has for decades been difficult to determine. Astronomers recently used ghostly particles called neutrinos to verify the ...

When a pair of ultradense cores of dead stars smashed into one another, the collision shot a bright jet of charged subatomic particles through space. Astronomers thought no such jet had made it out of ...

We learned how motion gives matter its mass, but how does motion affect time? We learned how motion gives matter its mass, but how does motion affect time? Let’s dive deeper into the true nature of ...
