Kinda fucked up tbh

What about Bogdan, who was catapulted into space in 1377 in a freak trebuchet accident which was never recorded?
- that would be the first time not all of humanity was on earth
  
  You mean you don't think he's still out there?

gotta keep someone up there to watch space just in case it gets the wrong idea
- Well, someone needs to keep the lights on in the ISS....

This must be a glitch someone's tweet from a different timeline went through ours.
- Long term occupancy of the ISS started in November 2nd, 2000. Since then there has always been at least one person Manning the ISS.
  So at least one human has not been on earth for every day since then, thus, all of humanity was last on earth on November 1st 2000. The statement is factually correct.

It’s Tim Curry in the only place safe from Capitalism.

This is kind of mind blowing.
- It's the year 3250. Two harsh desert planets are in a bitter dispute over mineral and water mining rights over the asteroid belt. The Mars coalition insists that Earth may lay claim only to those rocky bodies that fall past her orbit. Earth insists that anything beyond their respective atmospheres is fair game. They use loaded language and plan to argue that an 'atmosphere' is one that sustains life, meaning she plans to mine uninhabited stretches or Martian soil too. There is serious debate on Earth of the inhabitants of Mars are even human anymore, cross breeding has become exceptionally difficult. Martians have a lower natural fertility rate and often need IVF to reproduce. Earth gravity is too strong for martians to safely return to the home planet, and so few Earthlings have ever seen one in person.
  The dispute, unresolved, leads to the second interplanetary war. A billion people will die on both planets. Mars will lose precious irreplaceable atmosphere. Earth will lose access to much needed water. The conflict only ends when neither can keep up the fight any longer.

Holy shit.
I've never been alive in a time when every human has been on Earth. That's crazy to think about...
- Being born after 2000 should be illegal
  
  As a fellow old person, former millennial, I agree.
  
  They're old enough to have finished a master's degree
  
  finally someone said it, thank you
- I had lived in exactly 2 days in my life time in which every human was on earth.
- Get off my lawn.
  
  This planet ain’t big enough for the two of us.
  
  ;n;
- I have... and by way longer than I want to admit.
- Saaame
- If you like pedantry, people have definitely flown in vehicles and even jumped.
  
  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.
- zygote.
  
  I'M FREAKING 24!!!

Well, technically speaking, we all are in space.
- Are we technically a space fairing civilization?
  
  unfortunately i feel you can't call yourself spacefaring unless you actually control the ship, and we have about as much control over our trajectory as a mosquito has control over the amount of blood inside a blue whale
- We are all passengers on a generational space vessel.
  
  We need a better navigator, though. We keep going around in circles.

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

By 2030, everyone will most likely be back on Earth again when the ISS gets decommissioned :(
- Well, maybe sooner than 2030... https://spacenews.com/musk-calls-for-deorbiting-iss-as-soon-as-possible/
  
  i agree with him, provided we de-orbit it onto his skull
  
  Let's hope that Musk has nothing to say in that when it is time
- China will still have an operational station. Probably.
- China has their own ISS.
  
  Wouldn't that . . . not be an ISS?

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
- I mean 30,000 feet is 9km. The Kármán line is 100km. The ISS is at an average altitude of 400km.
  It's a bit like saying people in planes don't count as flying because then people on trampolines should count.
  
  Are you saying that people jumping ARE on earth? Because I disagree.
  
  Also people who live in a basement, or cave, or underground complex of some kind, or who are currently caving, ... they also aren't 'on' Earth, they're 'in the Earth', ... and people currently in submersibles, under the water line, well they're not on the surface, they're in or under the ocean or w/e, by this grammatical level of pedantry.
- We already have a definition for this, the Karman line.
- 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.
  
  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.
- Unless you define "on earth" to be "below the Kármán line. The Earth's atmosphere is probably to be considered part of the planet, else gas planet like Jupiter get difficult to talk about consistently. Atmospheres don't have a proper "cutoff", they just get thinner and thinner until they gradually become insignificant, so some cutoff is going to have to be arbitrarily defined to make the distinction useful.
  
  Karman line could be a good limit sure, but I think the orbit still kinda makes sense to include "on the planet".
  Say for example if the apartheid baby gets his Mars colony thing going, from Earth's perspective it wouldn't make much difference if a person is standing on Mars surface or on the orbit - we could say that the person is on Mars.
- Let's make some artificial rule like you need to be not on earth for 48 hours to be not on earth or something ...
  
  Can be at rest in your own reference frame without falling to earth?
  
  I think better would be to include Earth's orbit as "on Earth". This makes sense even if we expand our scope of operations to other planets
- When I jump, I am not in earth.
  
  No, you're over Earth.

Pssh, those are only the humans we know of.
- It's said, that life here began out there...

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

must have been a pretty scary halloween that year

I want more of these facts but I’m not signing up for Twitter

Space is a priority so we can ignore climate change. Rockets put our many many plane flights worth of pollution, elon musk has done over 30,000 of them (mostly for StarLink). Quite a few ended up just dumping raw pollution and parts into the ocean.
No price is paid but by the environment.
- Space is a priority so we can ignore climate change.
  I have a teacher that once said that even if we nuked the entire planet and gave 100 years to terraform Mars. Mars would still be less habitable than Earth. Colonization of space in the near future is a pipedream.
- 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.
  
  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.

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.
