Kinda fucked up tbh

By 2030, everyone will most likely be back on Earth again when the ISS gets decommissioned
China will still have an operational station. Probably.

Holy shit.
I've never been alive in a time when every human has been on Earth. That's crazy to think about...
If you like pedantry, people have definitely flown in vehicles and even jumped.

Are you saying that people jumping ARE on earth? Because I disagree.
Are there enough trampolines on earth that we could reasonably expect that at any time there is at least one person in the upper part of their jump on a trampoline?

Hmm, I think this logic kinda fails because if astronauts are "not on earth", then neither are air travelers.
Astronauts orbiting earth are just couple kilometers higher altitude
Spent a moment thinking about this and I think there's an implied definition for what "on earth" means that we intuitively accept but don't ever really need to state.
If your projected free-fall trajectory both forward and backward in time intersects with the surface of the earth then you are "on earth".
Standing on the ground? Intersects twice.
Thrown rock? Intersects twice.
Person in an airplane? Intersects twice.
ISS? No intersection.
Incoming impact meteor? One intersection. -

2012 is still pending just waiting for us all to be gathered up so as to not have any loose ends.

Well, technically speaking, we all are in space.
We are all passengers on a generational space vessel.

Wouldn't that . . . not be an ISS?

Not true if you take into account all the kids jumping at any given moment.

How do they know there wasn't someone jumping at ever second of every day somewhere on earth up til then? Also people in airplanes.

Rockets are launched so infrequently that their effect is negligible compared to other sources of pollution. They're definitely still a problem (debris falling on populated areas is a concern), but the aviation industry burns a rocket launch worth of fuel a few times per minute.
wrote on last edited by [email protected]263 rockets in 2024 alone. A 747 carries 10 tonnes of fuel to burn, a rocket carries 1,500 tonnes of fuel to burn.
Seems like they're both bad, but rockets don't have as much of a point to them.

I have... and by way longer than I want to admit.

We need a better navigator, though. We keep going around in circles.

You see, you just take out the 'I', and... oh.

I like pedantry but want to go the other way. The ISS orbits in the thermosphere, still inside Earth's atmosphere. I say that you haven't really left Earth until you exit the atmosphere.

What's wrong with the karman line?

Incoming impact meteor? One intersection.The ISS was launched from Earth, in pieces but still it's of Earth origin, and will eventually fall back to Earth. It's inside the Earth's atmosphere and experiences drag. It's orbit has to be adjusted and maintained.

Yes, that's all true, but none of that describes its free-fall trajectory. Drag causes it to deviate from free-fall very slightly, and it definitely wasn't in free-fall when the pieces were launched from Earth

This is kind of mind blowing.

They're clearly not "jumping" they're pushing the earth away
That’s relatively true
