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.

Using the Large Hadron Collider (LHC), a team of researchers recently tested whether top quarks also follow the special ...

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 ...

More than seven years after it was founded in a Seattle co-working space, Relativity Space launched its first 3D-printed rocket on a test mission that began with a ...

your twin boards a spaceship and launches into space to travel through the universe at nearly the speed of light. Since, according to Einstein's special theory of relativity, time moves slower the ...

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 ...
