The party that didn't go off with a Big Bang: Stephen Hawking held a party for time-travellers - but no-one turned up...

It is the ultimate test for time travellers - hold a party for them, but don't post the invites until after the event.

But sadly, when Stephen Hawking tried this, he was left to his own devices - for across all of time and space, his invite to literally anyone who ever will exist landed on deaf ears.

Professor Hawking offered this as 'experimental evidence that time travel is not possible' - although we secretly hope that by publicising the party's existence (held on June 28th 2009), someone in the future might retroactively decide to visit.

A party to remember until the end of time: Stephen Hawking waited and waited, but no-one turned up...

According to Ars Technica, the Brief History of Time author explained: '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.'


It is a sad, but quite intriguing, image: Professor Hawking in a room by himself, surrounded by canapes and champagne, and expectantly waiting for the door to open or some kind of Doctor Who-style TARDIS to appear in the room thanks to some timey-wimey loophole assistance.

In fact, you can see this poignant vignette for yourself, for the party was filmed and put on YouTube.

You're still welcome to come at any time: Your invite is here

Still, perhaps it was a good thing that no-one came.

For Hawking said that while Einstein's theories alllow for time travel into the past, but that 'it is likely that warping would trigger a bolt of radiation that would destroy the spaceship and maybe the space-time itself'.
