Though there is an overwhelming amount of information floating around out there about the theory of relativity in all her guises, I was stumped last week when my eight year old nephew asked me to ...

Why can't anything travel faster than the speed of light? Do black holes really suck? And why is the universe expanding? These are just a few of the questions author and astrophysicist Jeffrey Bennett ...

Yesterday, I wrote about the core concepts needed to understand quantum physics, which is one of the two pillars of modern physics. The other, of course, is the theory of relativity, the full and ...

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 ...

Scientists may be celebrating the 100th anniversary of Albert Einstein’s general theory of relativity, but there was also a death in 1915. It was one of the many deaths of simple and intuitive physics ...

What if the Big Bang didn't begin with a singularity? This point of infinite density, which so divides physicists, could be avoided. A new approach to quantum gravity suggests that the universe may ...

Albert Einstein released his general theory of relativity at the end of 1915. He should have finished it two years earlier. When scholars look at his notebooks from the period, they see the completed ...

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.

One hundred years ago this month, an obscure German physicist named Albert Einstein presented to the Prussian Academy of Science his General Theory of Relativity. Nothing prior had prepared scientists ...
