Throughout the Media was the message to read, that postulated by Einstein Gravitational waves were actually detected. But what are gravitational waves and what they are doing exactly?

Besides the way of proof for the existence of black holes has been furnished, which is probably one of the reasons, why demonstration of gravitational waves makes such a wave. Black holes are fascinating, almost as fascinating as the fact, it took one hundred years, was demonstrated to Einstein's theory. Next Video tells us very clearly, What are gravitational waves, as they distort the space time and what that actually means, „distort spacetime“.

Space and time are interrelated. Therefore, very heavy masses stretch and compress the space - it created so-called gravitational waves. The animation explains in a simple manner the phenomenon of gravitational waves and how they distort spacetime.
