| Abstract | This event, so far unique, beautifully confirmed the standard views on the gravitational waves produced by a merger of two neutron stars, but its electromagnetic multi-wavelenth observations disagreed with the numerous initial versions of the “standard fireball model(s)” of gamma ray bursts. Contrariwise, they provided strong evidence in favour of the “cannonball” model. Most uncontroversially, a cannonball was observed at radio wavelengths, with an overwhelming statistical significance (>17 σ), and travelling in the plane of the sky, as expected, at an average apparent superluminal velocity V$_{app}$ ∼ $4 c$. |
