Steven Hawking once set up an experiment too disprove the idea of time travel becoming real by hosting a party, and only telling people the day after

What ways can this experiment be debunked?

It’s not really an experiment that proves anything one way or another so there’s nothing really to debunk. If time travelers had shown up then that would be proof that time travel is possible. But since nobody showed up we don’t learn anything one way or another.
