While the equation E=mc 2 is famous throughout the world, it was just the first step in Albert Einstein’s discoveries. The formula, describing the relationship between energy and matter, laid the ...

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 ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the physicist ...

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 ...
