Stephen Hawking’s time travel proof – none turned up to his funeral

by | 13th, May 2018

Time travellers are invited to come to Stephen Hawking’s memorial service in June. We expect – as he himself would have expected – none of them to turn up. There being rather an in-joke going on here.

Hawking’s work was rather famously about black holes, wormholes an other bits and pieces of weird physics mixed with astronomy. And it’s those weird bits which some think hold the secret to time travel if that is indeed possible at all. We’re really pretty certain that there isn’t – and isn’t going to be – some little box that allows us to go forward to next Tuesday nor to go back. All those sci-fi stories about being able to get the racing results and make a fortune aren’t going to come true.

But Hawking’s work was all about this sort of thing. And some of his theoretical results said that it might be possible using these weird bits of astrophysics. Or not, as the case may be. So, thus the joke about the memorial service:

A thousand people have been invited to attend a June memorial service for theoretical physicist Stephen Hawking, whose ashes will forever be interred next to Sir Isaac Newton’s in the halls of the 11th century Westminster Abbey church.

And travelers from the future, it seems, are permitted to attend.

The joke here being that Hawking had already tested the idea a few years back:

I have experimental evidence that time travel is not possible. I gave a party for time-travellers, but I didn’t send out the invitations until after the party. I sat there a long time, but no one came.

No, really, he did.

And that’s a rather good proof of time travel too. Imagine that it does exist. So, where the hell are they all? That there aren’t any is rather evidence that it’s not possible, isn’t it?
