What is the Dome Earth idea?

Lens adapted to this topic: Dome proponents’ claims and evidence

Dome proponents describe Earth as an enclosed system, often combining flat-Earth geometry with a firmament, a biological-cell analogy, or creationist readings of ancient cosmology. Some interpret rocket footage, space missions, or limits on Antarctic access as signs of containment. The cited descriptions document these arguments, while the available testing does not substantiate a physical dome.

• Some proponents define the dome as an enclosure or closed biosystem rather than merely a claim about Earth’s surface shape.
• Some modern versions use a cell or membrane analogy and reinterpret space exploration as staged or as boundary maintenance.
• A traditional firmament model depicts a solid vault above a flat Earth, with celestial waters and heavenly bodies associated with it.
• Some claims cite rocket videos or Admiral Byrd and Antarctica as alleged evidence for a dome or its boundary.
