The Moberly–Jourdain incident (also the Ghosts of Petit Trianon or Versailles, French: "les fantômes du Trianon" / "les fantômes de Versailles") is a claim of time travel and hauntings made by Charlotte Anne Moberly (1846–1937) and Eleanor Jourdain (1863–1924).
The Moberly–Jourdain incident disproved time travel
The statement says the incident made the claim of time travel, I said it disproved time travel. Given the context I should be right in that it's incorrect.
