Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light. Albert Einstein's 1905 theory of ...

Black hole and Big Bang singularities break our best theory of gravity. A trilogy of theorems hints that physicists must go ...

Here’s how it works. General relativity is physicist Albert Einstein's understanding of how gravity affects the fabric of space-time. The theory, which Einstein published in 1915, expanded the ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists ...

Einstein allowed his imagination to run riot, creating ‘thought experiments’ that questioned centuries of knowledge about time, space and motion. In 1905 he published a series of papers that ...

Some consider her accomplishment to be as significant as Albert Einstein’s general theory ... of mathematics surrounding Noether in her time. The daughter of a university math professor, Noether ...

This difference arises from Einstein's introduction of a key new element: the deformation of time, in addition to the deformation of space, to achieve the exact curvature of light. Are these ...

A rare ring of light surrounding a galaxy nearly 590 million light-years away from Earth has been discovered by a space telescope ... the Einstein Ring will remain for some time, allowing ...
