@jonelliott4985 Punctuation is there for clarity, not ornamentation.
FE'ers accept there is 24hr sunshine in the Arctic Circle because they can think they can explain it on a FE. They deny it occurs in the Antarctic Circle because they can't explain it (or even longer days in summer) and claim Antarctica is sealed off to prevent people finding out there isn't 24hr summer sun there. You can go to the southern tip of South America (Ushaia) and observe a 19hr day.
The radius of the globe is 3,900 miles. Mt Everest is 5.5 miles high. That is about 0.14% of the Earth's radius. Mountains don't contribute significantly to the shape of the Earth.
The deviation from a perfect sphere, e.g., polar oblation, is similarly minute on a planetary scale.
The Antarctica Treaty prevents military bases and requires visitors to adhere strict regulations for avoiding contamination of the environment there. It does not prevent anybody actually going to Antarctica. There is a booming tourist trade and various people have traipsed across it.
The tallest Antarctic mountains are about 16,000ft (about 3 miles) high.
The atmosphere is free-floating gases; there's no part of the atmosphere that doesn't have free-floating gases. No gas, no atmosphere.
Gravitational attraction is proportional to the squared distance from the object's centre of mass. Earth's radius is 3,900 miles; the gravity on Mt Everest's summit is about 99.7% that at sea-level.
Gases move according to whichever forces are acting upon them. They don't go looking for higher temperatures.
There is no flat part of a sphere; the Earth is a sphere and orbits the sun. It rotates on its axis every 24 hours while doing so. The axial wobble has a period of 24,000 years. There is no substantial orbital decay at present.
A vacuum is devoid of all matter including gases; it does not cause gases to liquify or freeze. Low temperatures do cause liquification which is probably what you're thinking of.
No, you do not need to personally go into space to determine that the Earth is a sphere. The ancient Greeks deduced it from the motion of the sun, horizons, angle to Polaris matching latitude, constellations changing with latitude, two celestial poles and lunar eclipses having a circular shadow.
There is nothing banning you from travelling around the world.
Observe the moon for long enough and you will see about 60% of it over time; while tidal locking keeps the same face pointed at it the interaction of sun, Earth & moon means there is a slight jiggle. With a high enough resolution you can also observe the shadow of lunar mountains and how they change with lunar orbit. It's clearly not a disk.
Light does not decay.
