I keep seeing versions of this post, which imply a bizarre misunderstanding of how we know the world.

Do people imagine that if we'd never observed galaxies or neutrinos or exoplanets or the cosmic microwave background, we could have *imagined* these things & that would be just as real?

Or that we've magically reached the point, just now, where we no longer need to observe the world?
