Debunking Flat Earth Misconceptions
Atmospheric pressure decreases as altitude increases. A pressure difference can occur without a barrier. Other factors, like gravity, can cause a pressure difference.
Flat-Earthers claim a pressure difference cannot possibly occur without a barrier, like Earth’s atmosphere next to the vacuum of space. In reality, it is not difficult to demonstrate that a pressure difference can exist without a barrier.
Atmospheric pressure decreases as altitude increases. There is no visible boundary between Earth’s atmosphere and space in terms of pressure. There is no abrupt drop in pressure where space begins.
Flat-Earthers assert that it is impossible for the pressurized atmosphere to meet the vacuum of space without any barrier. In reality, the pressure changes gradually. There is no sudden pressure drop between the atmosphere and space.

A vacuum implosion can occur if a sealed enclosure has less pressure inside it than outside it, and the structure is not designed to withstand the pressure difference.
Flat-Earthers use vacuum implosions to ‘disprove’ space travel in the vacuum of space. In reality, 1. it is possible to engineer structures that can withstand such a pressure difference; and 2. in space, the inside is pressurized while the outside is a vacuum, which simplifies the engineering considerably.
