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 ...

General relativity is a profoundly complex mathematical theory, but its description of black holes is amazingly simple. A stable black hole can be described by just three properties: its mass, its ...

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 ...

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 ...

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.

Astronomers have been searching for a mysterious substance called “dark matter” since the 1930s. Most scientists still believe it exists, despite many fruitless decades. Now we propose a new theory of ...
