> that very scale and effort seems to be problematic when it comes to reproducing the results of experiments First of all, LIGO is 2 observatories so every result out of LIGO was observed by at least two locations. There is also an independent project called Virgo which is making gravitational wave observations, and the results are being correlated with LIGO. They have made a number of overlapping observations, which further moves us towards reproducibility. Future observatories are also planned (like LISA), which will be another opportunity to further validate events.
