I was in a physics PhD program in the 1990s and remember attending a talk where they simulated a neutron star collision and showed what the gravitational wave chirp looked like and it was exactly like the real gravitational wave chirps they measured later.
So personally I like hearing about little ‘big science’ projects such as detectors for rare radioactivity (proton decay, dark matter recoils, majorana neutrinos) and this project which may lead to a sun grazing satellite.
