We spoke with theoretical physicist Brian Greene about Einstein's theory of space-time. Many scientists believe space-time is a fundamental concept. But Greene thinks there might be something ...

The pull of gravity is just matter sliding along the curvatures of space-time. Einstein shot to the pinnacle of celebrity in 1919, when British astronomers actually measured this warping.

Space-time may hide a bizarre new kind of black hole that causes Einstein’s theory of gravity to fail – and could solve the ...

A weak gravitational field indicates nearly flat space-time, and there Newton's theories seem to apply. But a strong gravitational field throws classical predictions off. Einstein postulated three ...

For over a century, quantum mechanics and Einstein’s general relativity have stood as the cornerstones of modern physics, yet ...

In 1905, Einstein published the first of his many papers addressing the shortcomings of classical physics about light and ...

Among these, Einstein manifolds play a crucial role as they satisfy specific curvature conditions that relate to the energy content of the spacetime. Recent research has focused on characterizing ...

Einstein’s big idea was the strange concept of space-time - the notion that space and time are woven together, and become distorted by objects with mass. Ten years before general relativity ...

Researchers at the Large Hadron Collider tested whether top quarks, the most massive known elementary particles, comply with ...

The length of time during which we understood gravity has changed: the general theory of relativity by Albert Einstein had another 100-year basis, for example, instead of a force between masses, ...

This mathematical framework allowed Einstein to describe curved spacetime and express physical laws in different coordinate systems. Tensor Calculus: Einstein adopted and expanded upon the tensor ...
