Since 1915 when Albert Einstein published his theory of general relativity, scientists have worked on testing its limits, and with the results of this 16-year test, it still holds up. Professor ...

Albert Einstein's general theory of relativity describes how the fabric of space and time, or spacetime, is curved in response to mass. Our sun, for example, warps space around us such that planet ...

Learn how researchers used Einstein’s theory of general relativity to create the most accurate simulations to date. Think of a black hole, and you might imagine a literal dark hole, but contrary to ...

Recent advancements in observational techniques have led to the capture of high-resolution images of black hole shadows, which are challenging the completeness of Einstein’s general theory of ...

In a simulation of the universe without commonly made simplifications, galaxy profiles float atop a grid representing the spacetime background shaped by the distribution of matter. Regions of blue ...

Albert Einstein’s mind reinvented space and time, foretelling a universe so bizarre and grand that it has challenged the limits of human imagination. An idea born in a Swiss patent office that evolved ...

The weak-equivalence principle is integral to general relativity, so these test results offer yet more support for a core theory of our universe. In 1916, Albert Einstein dared to declare that Isaac ...

From high school mathematics to differential geometry, general relativity, and gauge theory."I want to learn differential ...

This November, Einstein’s theory of general relativity will celebrate its 100th anniversary. Despite its advanced years, Einstein’s soon-to-be centenarian theory is holding up remarkably well. That’s ...

Michelson's interference experiment / by H.A. Lorentz -- Electromagnetic phenomena in a system moving with any velocity less than that of light / by H.A. Lorentz -- On the electrodynamics of moving ...

Albert Einstein's theory of relativity is actually two separate theories: his special theory of relativity, postulated in the 1905 paper, The Electrodynamics of Moving Bodies and his theory of general ...
