Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of ...

F = ma One of the most fundamental equations in physics, Newton’s Second Law of Motion, was formulated by Sir Isaac Newton in ...

A nearly century-old offshoot of Einstein’s general theory of relativity may hold promise for solving the mysteries of dark ...

Møller, C., “The Theory of Relativity”, 62 (Oxford, 1952). Bergmann, P. G., “Introduction to the Theory of Relativity”, 37, formulæ 4.19, 4.20 (New York, 1942).

Physicists hope that understanding the churning region near singularities might help them reconcile gravity and quantum ...

When first published, the article didn't include the now-famous equation E=mc 2 ... in answering them he developed the general theory of relativity ten years later.

This theory originated as the answer to the question: Is the special principle of relativity really contradictory to the field equations of Maxwell for empty space? The answer to this question ...

In particular this theory would unify the two great bastions of twentieth century physics - the general theory of relativity and ... be encompassed by a set of equations - or perhaps just one ...

But simple it isn’t. General relativity’s equations fail catastrophically at a black hole’s centre, known as its singularity, where the warping of space-time simply goes off the scale.

Einstein's theory of relativity predicted the presence of ripples ... What's more, when he tried to write a mathematical formula to describe how gravity waves work, he couldn't do it.

But his equations turned up a surprise ... against established classical (often called “Galilean”) ideas of the relativity of speed. If someone fires a bullet from a moving car, for instance ...
