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 ...
In the hunt for extraterrestrial life, we usually look for planets orbiting sun-like stars and icy moons. But there is another possible candidate—planets circling white dwarfs, the hot, dense remnants ...
Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in ...
Confining and rotating extremely cold atoms or molecules within atomic “Ferris wheels” made from laser light could test ...
A major accomplishment of Einstein's theory of general relativity, which views gravity as the result of deformations in spacetime, was that it could explain Mercury's orbit. In a new paper published ...
