It took Einstein 10 years to make the theory work for gravity too, which is how general relativity gets its name. The theory is a series of equations defined by Einstein. These equations combine ...

Mathematical equations have shaped our understanding of the universe, and these nine have played a key role in changing the world.

To account for gravity, time and space must be curved around massive objects. The math was very complex and the whole idea so strange that most people didn't accept it. But Einstein suggested ...

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

Nearby was Einstein’s wife, Elsa ... he had to slip a fudge factor into the equations of general relativity—a cosmological constant. While gravity pulled celestial objects inward, this ...

This equation is how atomic bombs and nuclear ... it did not explain the nature of gravity itself. Einstein knew that his ...

It modifies Einstein’s equations by introducing two functions, μ and η, which describe changes in gravity and metric ...

It opened up an entire field of physics, but left Einstein with some nagging questions. The problems of gravity and acceleration would not go away. After thinking about the problems for 10 years ...

Nearby was Einstein's wife, Elsa ... he had to slip a fudge factor into the equations of general relativity—a cosmological constant. While gravity pulled celestial objects inward, this extra ...

But ripples in spacetime seemed a little too far-fetched for Einstein. What's more, when he tried to write a mathematical formula to describe how gravity waves work, he couldn't do it. So Einstein ...

Research on Gravity in Line With Einstein's Theory ... line up with what Einstein's theory of general relativity ... Einstein's Equations Collide With the Mysteries of the Universe Nov. 11 ...
