So let it be written; so let it be done.

I'm 5'7. Anything that's to high for me to reach with a running jump is now considered space. I have spoken.

Provocative is such a kind way of saying misleading.

Planes lose that ability around 50k feet. Military planes get closer to 100k feet. 60miles is easily 3x that.

Yeah, but they left Miranda, so...

Super interesting. So the mda ice can store energy which can be released by heating it back into regular ice.
This was a good read op.

now china cares about legalities? wonder whose balloon satellite designs they stole to fly just outside the legal definition of near space

Is there a full resolution image somewhere? Or because I’m on mobile it’s compressed?

And? I'm not sure how this theory/discovery contradicts the other one

I hate to be 'that guy', but:
Dark matter and dark energy are completely different, and from my layman's understanding - having opposite effects.
Dark matter (DM) is used to explain excess gravity observed in the universe - an attractive force.
Dark Energy is used to explain the observed accelerating expansion of the universe - a 'repulsive' force (not technically true, but observationally convenient phrasing).
Black holes are postulated to be possibly connected to the dark energy thing.
Upvoted for Ace Ventura reference.

Its not fuzzy at all. You are either in orbit, or you are not.

I'd argue that, if you are able to overcome gravity via buoyancy and/or aerodynamic lift, you are not yet in space. If you need to use orbital velocity to stay up, then you're in space. That probably still leaves some room for argument, but it would be a pretty narrow range of altitudes in which to argue.

Stupid article title and even the premise seems like bandwagoning to get clicks. While there is no universally-accepted legal definition of where space begins, the spy balloon is nowhere near any of the proposed boundaries.
There is no dispute about being able control our national airspace at 60,000 feet.

Orbit is a speed not a height. The atmosphere puts a lower bound on where that speed can be "orbital" as you loose too much speed and even burn up low enough.

Europa, Titan, Ganymede, and Enceladus

Well it definitely doesn't begin at 40-60k up where they were located. 🤷
