Gravitational Waves

For the first time, scientists have observed ripples in space-time, so-called gravitational waves, which - triggered by a major event in the distant universe - reached Earth. This observation confirms an important prediction of the general theory of relativity formulated by Albert Einstein in 1915. At the same time, it opens a new window on the cosmos.

How researchers succeed in tracking down gravitational waves more

For the first time, scientists have observed ripples in the fabric of spacetime called gravitational waves, arriving at the earth from a cataclysmic event in the distant universe. This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos. more

After decades of intensive preparations, the researchers achieved their goal; on 14 September 2015 two detectors known as Advanced LIGO finally managed to ensnare gravitational waves more

In the 1970s, Max Planck scientists started working in the research field of gravitational waves more

Today, we cannot imagine modern astrophysics without the general theory of relativity: no matter if it's black holes, quasars, or gravitational lenses – it plays an important role in all these fields.  And when researchers try to track down gravitational waves, they are trying to confirm one of Einstein's predictions. The eventful history of the most famous equation of the century. more

Albert Einstein predicted their existence in the last century, but thought it would be impossible to discover them. Astronomers are now looking for them, nevertheless: gravitational waves. more
