Wiggs: (flat-Earth in this thread)

Air pressure doesn’t require a physical container — it requires a force. Gravity confines the atmosphere, which is why pressure is highest at the surface and drops with altitude.

Air pressure isn’t set by heat or by a physical container — it’s set by the weight of the atmosphere held by gravity.

The Moon has almost no gravity, so gas escapes >> no pressure. Mars has weak gravity, so it keeps a thin atmosphere >> low pressure. Earth and Venus have similar gravity, but Venus has vastly more atmospheric mass (mostly CO₂), so its surface pressure is ~90× higher — the heat is a result of that atmosphere, not the cause.

Jupiter is extremely hot yet holds enormous pressure because its gravity is immense. Hot gas doesn’t create pressure by itself — gravity retaining large amounts of gas does.

Jupiter’s pressure starts Earth-like at the cloud tops but rises continuously to tens of millions of times Earth’s surface pressure due to its immense gravity — despite being extremely hot.

I have a friend who is a zealous flat earther. He believes I am indoctrinated and that he has the knowledge to enlighten me. He believes it is more important to push his views on the subject than just get along and talk about more important things. He follows a guy who is planning to sail two boats to the outer edges of the flat earth and then beyond to unknown lands, I forgot to ask him how they intend to get through the firmament at the edges holding everything up but it is his firm belief that this guy is like the second coming and he is tempted to join him on his journey (true story).
