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 ...

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 ...

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

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 ...

This dimple in space-time is the result of what we call a gravity well, and it was first described over 100 years ago by Albert Einstein's field equations in his theory of general relativity.

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 ... due to general relativity’s linking of space with time, energy alone is not conserved but a ...

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 ...

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 ...
