Gravitational Wave Detection on Ground and in Space – The New Window to The Universe
Wednesday 3 October 2018, 18:00 – 19:00
Location: Bremen Exhibition & Conference Center – DLR Hall
According to Einstein, gravitational waves are created by accelerated masses like in binary systems of Black Holes or Neutron Stars which circle around each other, approach each other, and finally merge. The gravitational wave signals carry information about the physics of the Black Holes, in particular of their event horizons, and of the highly extreme states of matter inside Neutron Stars. Such gravitational waves can also be used for a highly precise method to establish a cosmological distance scale which will contribute to a further independent and improved determination of the Hubble parameter and of the dark energy in our universe. Furthermore, gravitational waves can provide a better understanding of the fluctuations of matter and space-time in the very early universe and its inflationary phase. Beside electromagnetic radiation, gravitational waves thus provide a second and very clean way to observe the dynamics of Black Holes, stars, and the whole universe.
