The Yerevan Dome Collapse is a disputed 1994 immersive theatre performance held inside a decommissioned Soviet planetarium in Yerevan. Its connection to the Beach Surgery franchise is debated; it predates the novel's 2020 publication by 26 years, yet fandom has long speculated whether it is a retro-causal precursor—a work the novel summoned backward—or an independent coincidence.
**Documentation.** The event is known through seventeen photographs, two audio cassettes, and eyewitness testimony of 5–8 surviving participants. A single VHS recording of the final session was discovered in a Yerevan estate sale in 2008; it deteriorated rapidly and was partially digitized. No contemporary newspaper coverage has surfaced.

**Content and description.** Participants entered the darkened dome and were guided through what witnesses describe as a choreographed "collapse." The dome's acoustic space was flooded with low-frequency tones; participants moved freely; at irregular intervals, the creator(s) read passages in English and Russian—sometimes simultaneously, creating dissonant overlap. Eyewitness accounts diverge sharply: some recall a woman in a "red costume" at the center; others describe only the dome itself as protagonist. The final session ended in near-total darkness. One witness reported "the sensation of falling without moving."
The dome was demolished in 1997. The creator's name was either never made public or has been systematically erased from surviving documentation. [citation needed] A 2015 fandom thesis argued the work dramatized the glitch—that the dome's collapse represented the irreparable seam between the two halves. Skeptics counter that timing and coincidence are insufficient proof of connection.
