Scientists used the most massive fundamental particles to break special relativity, but even that didn’t work.

Space and time are “relative,” flowing differently for each of us depending on our motion. Einstein’s special theory of relativity, published a hundred years ago, also revealed that energy ...

Einstein's special relativity, established in 1905, unified space and time into a four-dimensional continuum. It relies on two core principles: Galileo's relativity and the constancy of light's speed.

Einstein came up with special relativity, which explained the relationship between space and time – and how they are related to each other. 'Special' means ‘in certain circumstances’ – so ...

Researchers at the Large Hadron Collider tested whether top quarks, the most massive known elementary particles, comply with ...

In the first study of its kind at the Large Hadron Collider (LHC), the CMS collaboration has tested whether top quarks adhere to Einstein's special theory of relativity. The research is published ...

At least, that's what we understand through Einstein's special theory of relativity, the revolutionary theory that united space and time can become interchangeable. And while it might be easy to ...

Tim Ellis, cofounder and CEO of Relativity Space, is competing against SpaceX in the booming space launch business and reinventing manufacturing in the process. Relativity CEO Tim Ellis on the exc ...

Relativity promised to disrupt launch by taking a somewhat niche technology in the space industry at the time, 3D printing, and using it as the foundation for manufacturing rockets. The pitch worked.
