When an object moves extremely fast—close to the speed of light—certain basic assumptions that we take for granted no longer ...

Einstein’s strangest optical illusion has been captured—thanks to lasers, a cube, and a bit of artistic inspiration.

Machine learning helped show how harnessing the weird effects of Einstein’s special relativity could enable a new kind of ...

To do this, they introduced a novel mathematical object they call the space-time dimension field. This field acts as a kind ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity ...

This is the central consequence of Albert Einstein's special theory of relativity. The object then has a different length than when it is at rest, and time passes differently for the object than ...

When an object moves extremely fast – close to the speed of light – certain basic assumptions that we take for granted no longer apply. This is the ...

Fast-moving objects don’t always look the way you’d expect. When something travels near the speed of light, strange things ...
