Einstein’s general theory of relativity—the idea that gravity is matter warping spacetime—has withstood over 100 years of scrutiny and testing, including the newest test involving supermassive black ...
An international group of scientists has been studying how the structure of the universe has grown over the past 11 billion years. These researchers recently announced findings about how gravity ...
When you open a map app on your smartphone, your current location is displayed as a blue dot.With an error margin of just a ...
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 ...

The length of a second has been redefined twice so far—a story about 'time' as changed by Einstein
Recently, there is something that has been on my mind. It is the idea that the definition of a second might change.I am not a ...
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 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 ...
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 ...
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 ...
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 ...
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 ...
