Kinda fucked up tbh

The Sun isn't stationary
but it also goes around in circles, or maybe it's more of a spiral

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/

another circle maybe? does anyone really know?

i mean, even those guys who went to the moon still stayed within a very close proximity to the earth compared to the size of the solar system
only when people travel to mars they will really have left the earth
The Moon is basically Earth territory. You can't go to Hawaii and claim you left the US.

Wouldn't that . . . not be an ISS?
The CSS then. They just have a problem aligning it.

So basically, the Karman line is the theoretical highest point that an airplane can fly, or at least it was when it was calculated. If it were recalculated today it would be higher because of technological advancement. The definition used by the agencies that define it as the edge of space set an altitude near the originally calculated line. The functional difference between being above the line and below the line is that the keplar force will keep an object above the line from falling to Earth within 24 hours while drag will slow the object below the line enough for it to fall back to Earth within 24 hours. It's fine as a functional definition but I see no reason that it should be universally applied. In the scope of this discussion why should we consider something that will fall back to Earth in 25 hours not be on Earth but something that will fall back to Earth in 23 hours to be on Earth?
That's highly pedantic, you need to draw the line somewhere. At 120 km you get long-ish sustainable orbits, at 80 km objects decay within a single orbit. The ISS sits at around 420 km, well above that
Btw, the airplane limit calculated by von Kármán was closer to 80 km, the 100 km limit is not based on his calculations.

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

gotta keep someone up there to watch space just in case it gets the wrong idea

The Milky Way is in a sort of orbit around the center of the Local Group which is the name for the local group of galaxies. It's not a clean circular orbit and it's not possible to calculate the rotation time, because the pull from other galaxies is stronger than their collective centre of point of gravity, but sure, it rotates overall on that scale too.
The next levels are different. The Local Group is part of a larger supercluster of galaxies that do not seem to rotate. It's more like flows of galaxy clusters. Depending on the point and scale we look at, it may be shrinking or expanding.
Perhaps there is some rotation to it, but the scale of both distance and time is so incredibly large that it's meaningless. -

I had lived in exactly 2 days in my life time in which every human was on earth.

Well, technically speaking, we all are in space.

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.

sounds like they spent a lot of time coming up with that name
jokes aside, thanks for the interesting info!

What about Bogdan, who was catapulted into space in 1377 in a freak trebuchet accident which was never recorded?
