I’d go with the mesosphere, because that’s where meteors burn up. That’s a little below the karman line and is defined by actual qualities, instead of an arbitrary number. Regardless, both exclude the ISS. :)
No human has ever been not gravitationally bound to the earth. So really this type of showerthought seems to be too early. If we send astronauts to Mars, it will be easier to say they have been separated from Earth.
Would you count a permanent base on the moon? I think it should, since you’d be more impacted by the moon’s gravity than Earth’s, despite still being in Earth’s orbit.
Are we certain there is a moment before that date that every single one of the ~6 billion people isn’t mid jump?
Literally a leap second
Or on an airplane
Maybe we can amend the definition of “on Earth” to “inside the atmosphere” for purpose of that tweet
No! We most dive deeper into Achually Land!
How far does “the atmosphere” go? Because technically the ISS is in the thermosphere, which is part of Earth’s atmosphene.
Already, let’s go with the karman line like everyone usually does.

Are you an astrophysicist?
No, just your garden variety nerd.
I would go with what the professionals use.

I like this.
It’s really the only non arbitrary answer.
Yeah, that’s probably a better metric.

The moon and everything on it is gravitationally bound to the earth. So I would not count a moon base as having escaped the Earth.
So, is the next set of goalposts that we need to except the solar system?
Planes are supported by the gas that is part of Earth, it’s not a lot different to boats that are supported by Earth’s water
Well duh, at nighttime when everyone is asleep
My bedridden grandmother is ruining it for us all
Also: air travel is a thing
