(at no particular order)
- PRACTICAL DEMONSTRATION of the oceans curving: they should drop 8 inches for every mile squared, but all water at that scale is always level. Indeed, the very word 'aqua' means 'level' and is the very basis for establishing the level in all construction and engineering work
- PRACTICAL DEMONSTRATION of the accelerating, spinning "Earth ball": no human sense and no accelerometer ever has registered the tiniest such motion. In fact, every human experiences the Earth as a level, motionless plane, and any and all engineering, military, construction or logistics sector assumes a flat, motionless plane. No such thing as the air being left behind, the Earth rotating under aircraft, rain falling sideways and other absurdities
- PRACTICAL DEMONSTRATION of gas pressure or even a gas pressure gradient without the necessary antecedant of a container, or in simpler terms a demonstration of gas being held against empty space without expanding into it. "Space", as portrayed in movies and some websites is a second law of thermodynamics violation: does not exist, because it cannot exist
Astronomy is not a science: it cannot progress beyond the first step of the scientific method, as nobody can vary and manipulate the variables involved. Pointing at the sky and declaring, concocting stories, "consensus" and authority are not science: science is strictly the process of establishing cause and effect relationships in natural phenomena
