There’s an innumerable number of reasons no one showed up, only one of which is that backwards time travel isn’t possible.
One of which is that Stephen Hawking threw a lousy party.
Take that back!!
The other one is that most people haven’t herd of it, so I doubt the knowledge of this party will travel that far into the future.
Someone who put work and effort into developing time travel will have heard of it. Unless it happened after a complete destruction and rebuild of civilization or two.
We’re in one of the unlucky few possible resulting timelines in which no one showed. My friend from timeline 3f-1933847.12b told me that their party is still going. Every few hours more travelers turn up with a fresh keg, and whatever their generation’s party drug is.
It’s by far the most plausible but sure, if you ignore Ockham’s razor, sure, it’s only one of many explanations
Can you imagine if someone showed up and his party became ground zero for a worldwide pandemic of future diseases for which we don’t have cures yet?
Hawking gets a Covid sample from a time traveler in 2009 and immediately travels to the Wuhan lab to study it and look for a cure, he successfully delays the pandemic and he almost gets to a cure but a bad guy time traveler comes to kill him in 2018 and without the watchful eye of Stephen Hawking, the world falls to chaos.
I’d watch that movie.

“The Big Time” by Fritz Leiber is one of my all time favorite novels. His time travel works on the principle of 'The Law Of Conservation Of Reality." There’s only one timeline, and it’s possible to change it, but it requires a lot of work.
If you go back and kill baby Hitler, he’ll come back to life and no one will remember anything. It takes vast armies fighting thousands of secret battles to change one thing. But when a Big Change hits, look out!
I’ve never read any Fritz Leiber, but he’s cited as a major influence by Zelazny (and Butcher, Donaldson, Stephenson, etc.)
Maybe today is the day I dig up and start reading Fafhrd and the Grey Mouser.
Good place to start.
Hawking concluded it is impossible because nobody showed up to his party. Zero thought was spent wondering if it was a party worth showing up to.
It would have been really awkward for everyone involved if someone stumbled into his party by mistake and freaked him out.
The problem is he only told us when it was, but not where.
He did divulge the location afterwards.
Correct me if I’m wrong:
I live in a timeline where time travel has not yet been invented. Even if someone invents it in the future and travels to the past to the party, that’d create an alternate timeline where the party is attended and civilization leaps bounds ahead in glorious post-scarcity, magical socialism fashion.
But nooooo since the timeline was forked at that point, no matter how many people do, in fact, attend the party, I’m stuck in the “strand” of the timeline when no one ever did because time travel has not been invented.
Depends on how you see it. It could also be that for some reason or another even with backwards time travel no one shows up. And thus you avoid having a paradox
Or it could be like a time portal so once you build one you an travel back to any point it existed in but one to a point where it doesn’t exist since you need time travel infrastructure
Or the technology for invisibility arrives before time travel so they were there, just undetected. Absence of evidence is not evidence of absence.

I mean, that for the most part makes sense. Although in that case, wouldn’t it have been reported that “no one attended the party but the food and the snacks were somehow missing”?
That said. Unsure how exactly it went but I read somewhere that if you had the power of True Invisibility, that is being undetectable at any wavelength of light, then you’d basically be able to simulate negative mass, and from there to “time travel” it’s kind of a straight line.
My theory is, time travel is possible but humanity went extinct before we got to that point.
