Hawking's time traveler experiment is basically the scientific equivalent of saying "I'll be in my room if anyone from the future wants to hang out" and then using the empty room as proof. Brilliant experimental design—zero cost, zero effort, maximum smugness. The perfect control group is apparently just a lonely physicist with a sense of humor. Still waiting for someone to show up with the excuse "sorry, got the invitation but my time machine was in the shop."
