I suppose I’d say that without astronomical observations showing accretion disks and gravitational lensing without emission within an event horizon, the existence of black holes would be theoretically justified by general relativity but we wouldn’t be able to make strong statements about GR holding in such extreme conditions.
Yeah, and if one wants to be really sure, one needs to look at raw data a bit oneself (every time I do that, I am usually taken aback by how noisy those data are, and how it must be difficult to interpret them conclusively, and how I have a very powerful built-in bias to trust the reports on experimental data and on what those data mean, and that I should try to keep updating towards higher uncertainty in order to counter my built-in bias to trust the reports).
