Let's rewind the clock back…oh, I don't know, let's say a hundred years. It was 1917, and Einstein had just developed his ...

Einstein’s theory of gravity — general relativity — has been very successful for more than a century. However, it has theoretical shortcomings. This is not surprising: the theory predicts its own ...

Scientists understand gravity pretty well when it comes to two objects, but add a third, and you’ve got chaos—a system that’s impossible to explain with our simplest equations. But you also have a way ...

It isn’t often that physics produces news that diverts the mainstream media from politics, crime and sports. But, now, in the space of four years’ time, physicists have twice elevated the intellectual ...

A century ago, Albert Einstein became famous. Sure, he was already well-known among physicists. But the world at large learned his name only after November 1919, when news broke that his theory of ...

Scientists have attempted to disprove Albert Einstein's theory of general relativity for the better part of a century. After testing and confirming Einstein's prediction in 2002 that gravity moves at ...
