Albert Einstein's theory of relativity is one of the pillars of modern physics. Inititally developed from thought experiments, it is now supported by a large number of different experiments and observations. It is therefore one of the most stringently tested physical theories. We take a look at the foundations and observed predictions of this theory. [more]

More than 100 years ago, Albert Einstein calculated that space and time can wobble and vibrate like jelly. These vibrations, known as gravitational waves, are created when stars explode or black holes collide. After researchers first observed these gravitational waves in September 2015, almost a hundred such observations have been made to date. They provide unique insights into the dark universe and its secrets. [more]
