On July 28th 2009 the esteemed theoretical physicist held a massive party for time travelers. The story goes that he planned the party carefully, rented space and catering. Only no one was invited until after the party. The only people to arrive would have to be time travellers!
“I have experimental evidence that time travel is not possible” — Steven Hawking
But what if there is another explanation? What if the party did happen? What if time travelers from throughout the future time-lines did arrive? Maybe no one remembers. Maybe no one can remember.
