Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...
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 ...
After Albert Einstein published his special theory of relativity in 1905, he spent the next decade trying to come up with a theory of gravity. But for years, he kept running up against a problem. He ...
It stands among the most famous theories ever created, but the general theory of relativity did not spring into being with a single, astonishing paper like the special theory of relativity in 1905.
A rare manuscript featuring early calculations that led to Albert Einstein's general theory of relativity sold for just over $13 million at an auction in Paris Tuesday, becoming the most expensive ...
One hundred years ago, a young physicist presented a paper to the Prussian Academy of Science — a paper that we now recognize as symbolizing the birth of general relativity. By this time, Albert ...
