  We’ve been yelling into space like it’s open mic night — blasting radio waves, mailing golden records like cosmic mixtapes, pointing giant satellite dishes at the void — and the universe has responded with the digital equivalent of “seen ✔️” and nothing else. So either we’re alone… or something out there took one look at us and went, “Yeah, no thanks.” Now flip the vibe. Imagine you’re in a pitch-black forest at night. You hear branches snapping.
