Under the conditions of the Hamiltonian principle, information is exchanged between two masses during an interaction by ...

A new recipe for gravity could help solve some of the ... operator leads to a new "entropic action," and to modified Einstein ...

The Einstein field equations are a system of second order, non-linear, coupled differential equations in 4 variables. As you can imagine, solving such a system is not easy. If the system possesses a ...

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 ...

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 ...

Researchers say they may have achieved Einstein's vision of a "unified field theory" that can unite two of nature's ...

Although Einstein is a legendary figure in science for a large number ... for everyone — his most enduring discovery is also the least understood: his theory of gravitation, general relativity.

"My favorite equation of Einstein's is when he derived the stimulated emission of radiation," deGrasse Tyson said during the annual Isaac Asimov Memorial Debate in 2012. "We study that in ...
