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

The discovery in 1998 that the Universe is expanding faster over time shook the foundations of cosmology. This finding ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum ...

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 ...

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 ...

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 ...

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 ...

Loeb cited the example of Einstein's famed field equations that link how mass, energy, and light can affect the flow of space-time. "The distortions of time or space are minuscule unless one ...

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 ...

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 ...
