The second official single from Miss Anthropocene, "So Heavy I Fell Through the Earth", was announced via Instagram on November 11, 2019, and released on November 15, 2019. The cover art and track listing for Miss Anthropocene were also unveiled on November 15. The track received positive reviews from critics who commented on the track's slower and darker sound compared to the previous single "Violence", with NME stating that it felt like a "slow-motion fall through the cosmos", noting the track's "thick layers of bass" and "Grimes' dangling voice". Pitchfork labelled the track a "six-minute downtempo odyssey" with "forceful theatrics".
