Have we really measured gravitational waves?

In 2017, a Nobelprize was awarded for the direct detection of gravitational waves, as predicted by Einstein's theory of General Relativity. But really we are still no sure that the events are indeed of astrophysical origin and not misidentified noise that originates on Earth. In this video I tell you what gravitational waves are, how to measurement (directly and indirectly), what the problem is with the existing direct detection, what's the matter with LIGO's Nobelprize winning figure, and what's with the glitches.
