Never before have there been so many people on Earth. The new world creates new challenges for us living together, one of the biggest being the infrastructure in the world we live in.

A milestone in physics: In 2015, scientists proved the existence of gravitational waves. These waves travel billions of light-years through space, eventually reaching Earth and bringing us insights that were previously unattainable.

In September 2015, the world of science experienced a sensation: researchers in the USA succeeded in proving the existence of gravitational waves for the first time in the history of physics. A milestone. This proof opens up a completely new perspective on our universe - perhaps even on the birth of the cosmos itself, nothing less than the Big Bang. Gravitational waves are created when something gigantic happens in the universe: a stellar explosion, the merging of neutron stars or black holes.
