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 central consequence of Albert Einstein's special ...

Astronomers have finally watched a black hole do something Albert Einstein only described on paper: twist the very fabric of ...

For the first time, physicists have demonstrated a phenomenon known as the Terrell-Penrose effect, which causes an object moving close to the speed of light to warp before our eyes. The new findings, ...

Tiny “Ferris wheels” made from light and extremely cold particles could allow researchers to test a facet of Albert Einstein’s theory of relativity on unprecedentedly small scales. Theories of special ...
