As announced in February, two Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors recorded a gravitational wave signal born out of the collision of two black holes 1.3 billion lightyears away. Not only does this extraordinary detection corroborate the existence of gravitational waves, but it is also the first direct observational evidence for the existence of black holes which are among the most fascinating predictions of general relativity. Gravitational wave detectors now provide us with a new set of senses to explore the mysteries of our universe, thus heralding a new era in astrophysics.
On Monday 22 February, Dr Thomas Sotiriou and Dr Helvi Witek hosted a successful outreach event about this first direct detection of gravitational waves from the LIGO.
The event consisted of two talks that aimed to explain (in a way accessible to non-experts and the general public) the underlying physics, the most impressive aspects of the detection method, and the outstanding significance of this result:
18.00 - General Relativity, Black holes and Spacetime Ripples
Dr Thomas Sotiriou
18.30 - Searching for a raindrop in a stormy ocean
Dr Helvi Witek
The event was well attended and the feedback has been extremely positive. Well done to Thomas and Helvi for hosting this successful event! If you were unable to attend, both talks are now available to watch online.
