Albert Einstein’s general theory of relativity has been wildly successful at describing how gravity works and how it shapes the large-scale structure of the universe. It’s summed up in a saying by the ...

In this paper-covered pamphlet of eighty pages, which is sold for saxpence, Prof. Rice sets forth the doctrine of relativity: and not only this, but also (as prelimiriaries to it) the principles of ...

In the past quarter century, astronomical observations have led to discoveries that have literally transformed our conception of the universe. One such transformation occurred in 1998, when dark ...

Black holes exist in our universe. That’s widely accepted today. Physicists have detected the X-rays emitted when black holes feed, analyzed the gravitational waves from black hole collisions and even ...

At least 3,700 years ago,Babylonian mathematicians approximated the ratio of a circle’s circumference to its diameter. They inscribed their answer, the first discovered value of pi, on a humble clay ...

For more than a century, Einstein’s relativity has set a hard speed limit for the universe, with light as the ultimate ...

“What would it take for ‘warp drive’ to stop meaning a screenplay shortcut and start meaning a solvable design problem?” In modern relativity theory, the solution has shrunk from fantasy to accounting ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may rewrite that rule. When you purchase ...
