The Globetrotters are the human descendants from the famous basketball team, the Harlem Globetrotters. For whatever reason, at some point, the Globetrotters left Earth to the Globetrotter Planet. The Globetrotters are exceptional basketball players specializing in basketball tomfoolery, who also have keen scientific minds, and have saved both the Earth and the Universe from disaster. Professor Farnsworth once created a team of Atomic Supermen to challenge the Globetrotters in a game of basketbal
This makes me think of the red dwarf episode where they find a Time Machine 3 million years into deep space, and use it to go back to the 15th century. They get disappointed and think it failed because they are still in deep space, and Krysten says no, it worked, we are now in 15th century deep space.
They then work out that you need both a Time Machine and an instant space travel machine like the holly hop drive. Especially since everything in the universe is moving.
And so, like, aliens might very well care but can’t find the right intersection of time and space to actually get there. :)
Take that back!!
One such possibility is that you can only travel to times where the device you’re using to do so exists.
More like a time gate than an H.G. Wells-style machine, but still a workable model.
Exactly, they’d know a lot more accurately what happened too, which raises another point as to why no one comes back here - imagine gong somewhere that you know horrible things are happening to children but you can’t say anything or save them because of the timeline…
Even if in the unlikely event Hawking didn’t know about it talking to him and not saying ‘that friend of yours epstine is a bad dude’ would be unbearable.
One the one hand you are correct.
On the other hand… Behold! An A in pi! www.spoj.com/problems/PIHEX2/
Yeah, now that I think of it more, I can’t see a single good reason for a time traveler to show up at this party. Going back in time to prove the existence of time travel to the past has a very good chance of handing control of time travel away to people who can undo your existence without you ever being aware of it.
Even if you just wanted a conversation with one of the brilliant minds in physics, it would be smarter to pick a random lecture or non-time-travel-themed party.
Yes, or someone did show up despite knowing the risks because they trusted Hawking to understand the dangers of revealing the secret of time travel and not sharing it with any living soul. If time travel were to ever become possible and somewhat commonplace then the chances are probably close to zero that everybody chooses not to attend this party (assuming the invitation remains famous for long enough). Perhaps the party was crowded with people thinking the same way.
It’s much more likely that it all just played out exactly the way Hawking said it did, of course. But it’s a fun thought experiment to play around with.
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.
