On the 28th of June 2009, Professor Stephen Hawking hosted a party at the Gonville & Caius College at the University of Cambridge. A large banner was strung between the walls, and written on it in capital letters was the message “Welcome Time Travellers”. Yes, this was a party for time travellers.
And there was a catch - the invitations were only sent out after the party had already taken place, meaning that only time travellers from the future would have known about the event and thus only they would have been able to attend.
The private room had been festively decorated in the theme of a champagne reception. In the middle of the room, a table had been laden with champagne flutes and plates of hors d’oeuvres.
Stephen Hawking subsequently told reports that he had sat there a long time, but no one had come.
