Title: "The first double pulsar system - a unique testbed for relativsitic gravity"
We recently discovered the first double pulsar system. This system
consisting of a 22-ms and a 2.8-s pulsar in a 2.4-hr orbit is the
most relativistic system ever found. Its property of providing
two clocks moving in a deep gravitational potential opens new ways
of probing relativistic gravity and the study of neutron stars and
pulsars in general. I will describe these opportunities, present
the latest results and conclude with an outlook into the future
where the Square-Kilometer-Array (SKA) promises the study of Black Hole
physics with pulsars.
