Context: He’s in the files
Is it because our solar system is hudling through space at over 1.5 million miles per hour, so anyone who time travels will find themselves alone in an empty void?
Nope, not visiting that

There’s no universal frame of reference. Any theoretical time travel would likely need a beacon of some sort to calibrate their arrival point, meaning you could only travel back to the point time travel was established.

You know what they say: the best time to build a time machine is 50 years ago.
I think that’s basically the movie Primer too, they’d turn the machine on, go hide in an apartment for X amount of time, then go back to the machine and emerge 5 minutes after they turned it on and just walked away.
But gravity effects time, sticking close to a planet isn’t going to be hard.
Ironically enough the first (if we ever get them) time machines are going to be a hell of a lot like modern “UFOs” are described. You couldn’t risk landing on the planet, elevation changes are what’s really a nightmare to account for. Show up and hour early and everything is a foot higher because of how fast we’re spinning.
So you’d want a space craft, because space is big and empty. And realistically it’s going to take something bigger than a telephone booth or even the 1980s embodiment of Florida on four wheels with a hood designed to do cocaine off of to house a time machine.

I’ve seen this take a lot it feels like and it boggles the mind why. If someone figures out time travel they ipso facto will have figured out the space travel as well.
If you can travel through time you can travel through space.

That logic assumes that there is some universal way if measuring the position of the earth, but there is no absolute system for measuring position in space. Location, distance, velocity, and even simultaneity depend entirely on the choice of a frame of reference. And the frame in which the earth is stationary is no less valid than any other.
Also the type of time machine has a bearing here. The traditional H.G. Wells vehicle-type doesn’t jump, but moves smoothlythrough all the intervening moments in time, so there’s no reason it wouldn’t stay firmly on the surface. And a time portal that forms a connection to the same apparatus at a different time would have no problem either, since the machine itself doesn’t move except in the ordinary way.

If i had a vaccume and a carbon nanotube rotating such that the ends are moving at the speed of light, and another going the opposite direction, I would have a dimensional anchor as moving it would cause spacetime to exceed the speed limit.
Voila, I just created a sci-fi plot device

My theory is that time travel still follows the curve of the space time continuum.

Listen, dude: I’ve got a lot more concerts in my list before I get to your lame-ass party.
Would you have missed Metallica in Moscow for some party you assumed nobody would attend? Fuck no.
Now if you’ll excuse me I’m gonna go sell all your grandmothers some really strong modern weed to get into Hendrix, New Year’s Eve, 1969.
Can’t wait to hear Machine Gun live.

No need to assume. You already know nobody attended. And you can also be part of the joke if it’s one.

lame-ass party
Since the time traveler would be from the future, he’d have already known that nobody went to the party.

Right? We only show up in some timelines as a fucking joke.

Or… isn’t there the theory that time travel just creates an alternate world. but all timelines exist… so there’s a second line where there’s 50 people that brought their year 3000 band, and their instant ALS cure pod, partied with Hawking then arrested trump for his crimes before he could run for president.

Let’s see… the egotistical pricks that sued anyone that wanted to like them… in an authoritarian shithole… or hanging out with Stephen Hawking…
Tough choice. Can I convince Lars to sleep in the disaster bed? Or help them with arrangements so that songs that have about 1 minute of interesting music don’t have 8 minutes worth of filler?

There is also the idea that time machines work like telephones. You need to have a receiving end made first before you can call it.

Wasn’t it already a known fact? I swear I’ve read about it already like 5 years ago, and I’m not a time traveler.

He wasn’t known for being a great guy, just a really smart guy.
The name of the late Cambridge physicist was included in a 2015 email in which Epstein told Maxwell to offer a reward to any of Giuffre’s “friends acquaitonts [sic] family” who could prove false an allegation that Hawking had participated in an “underage orgy” in the Virgin Islands. Hawking, who died in 2018, has not been accused of a crime related to Epstein.

Now, I’m speaking hypothetically, legally, and for educational purposes only… you fast-forward a few decades and suddenly certain names appear in court documents and flight logs, not convictions, not proof of wrongdoing, just… associations. Enough to make a careful chrononaut say, ‘You know what? I’m not popping back in time to shake hands and eat shrimp.’
The absence at that party wasn’t evidence that time travel failed. It was evidence that it worked, and everyone who could come already knew how the story looked later.
History doesn’t just judge actions. It judges proximity. And no self-respecting time traveler shows up early to something that turns awkward in hindsight.
