I think his points are valid and shouldn’t be dismissed as “poetic blarney”. His words may inspire and other scientists to look into these details more and look for clues to decipher the photons that come from black holes. His statements are qualitative observations, just because something is not quantitatively measurable due to tech limitations doesn’t mean it should be dismissed (much of Einstein’s works was done in his head and confirmed decades later from experiments). Some advancements such as ability to watch for minuscule changes in stars and to determine planetary movements and sizes is probably a good example of some techniques that can be used for studying the photons that are coming off of black holes.. perhaps some day we may indeed be able to measure certain characteristics that give us clues to ancient photons.
