"Space": running on the waves of gravity

A hundred years ago, an inquisitive mind of a genius, Albert Einstein assumed that the universe is filled with gravitational waves, and even described their properties. To this day, scientists continue to look for them. The "Space" invites viewers to witness these searches in Hanover, Germany.

Thus, all objects of the universe - colliding black holes, collapsing stars, planets - create ripples in the fabric of space-time, slightly distorting, deforming it. This "ripple" is the gravitational waves. 

Pulsars as detectors for gravitational waves

So far, they escape despite kilometer-scale detector systems of discovery: gravitational waves, vibrations of space-time whose survival Einstein forecast in his theory of general relativity. However, the detection of gravitational waves could soon be possible. And not with special detectors, but with ordinary radio telescopes that measure the arrival time of the radio signals from pulsars. The vibrations are there but not - as has been mostly assumed - as a sort of background noise, but it dominate individual signals of individual sources.
