The irony of one part of humanity: led mainly by People in the most prosperous country, measuring ever vanishing amounts of interference at the length of a proton to detect exploding stars, and they have to account for among other things the curvature of this planet to the millimetre.

Just a few miles away (and likely everywhere) in the same country there are many people growing in number who insist for some reason that the earth is flat. I am genuinely flummoxed why that's still a thing.
