A Black Hole is a cosmic body that is so massive that it warps space-time around it. Even light, the fastest thing in the universe cannot escape from it. The ordinary laws of physics do not work beyond the event horizon of a black hole. Giant black holes are formed in the centers of galaxies and can have billions of sun masses. Our own Milky Way has a giant black hole in the centre!

Gravitational Wave Astronomy is a completely new kind of astronomy. The first detection of a gravitational wave on 14 September 2015 has opened a new window on the Universe, a new way of perceiving our cosmos. Gravitational waves are like a new sense. If existing astronomy is like seeing, gravitational wave astronomy is like hearing. Gravitational wave detectors are extremely sensitive "laser ears" and can "listen" to the ends of the universe and into places normal astronomy cannot see.

LPF launched successfully on 3rd December 2015 at 4:04 GMT. After a picture perfect start, a journey to its destination some 1.5 million kilometers from Earth towards the Sun, and a successful release of the test masses, LISA Pathfinder began its job as a space laboratory on 1 March. With LISA Pathfinder, scientists have created the quietest place known to humankind. Its performance exceeds all expectations by far. Observing the most perfect free fall ever created was only made possible by reducing and eliminating all other sources of disturbance.

A series of lectures given at the Kerr Conference, hosted by the Max Planck Institute for Gravitational Physics (Albert Einstein Institute) to commemorate the 50th aniversary of the discovery of the Kerr Metric.

Speakers included Roy Kerr, the discoverer of the Kerr Metric, and Reinhard Genzel.

Quantum field theory and Einstein´s general relativity are not compatible with each other within the known physical laws. But if we want to understand what happens inside a black hole or at the Big Bang, we need a theory that combines both.
