The eternal scientific mood: the universe just exists with absolutely zero explanation manual, and scientists are left squinting suspiciously at reality trying to reverse-engineer the whole thing. Like opening a 13.8-billion-year-old mystery box with no instructions and discovering it contains quantum mechanics, dark energy, and consciousness. Scientists have been collectively making this Spider-Man face since the first caveperson looked at the stars and thought "hmm, that's weird." The entire scientific enterprise is basically just sophisticated confusion followed by slightly less confused note-taking.
