Countering Gravity

Gravity is not the only force. Other forms of force exist. Multiple forces can affect an object at the same time. Forces can counteract gravity, making an object move against the direction of gravity. These cases do not disprove gravity.

Objects can move against the direction of gravity, and flat-Earthers use it as “evidence” that gravity does not exist. In reality, there is at least a force other than gravity affecting the object, in the opposite direction from gravity, with a larger magnitude. Continue reading “Countering Gravity”


Drag or air resistance is a force acting opposite to the relative motion of an object with respect to a surrounding fluid. The magnitude of drag is directly proportional to the fluid’s density.

Flat-Earthers claim that because satellites lack an aerodynamic shape, they cannot be faster than airplanes. In reality, the air density at such an altitude is minuscule and will not produce a significant drag. Thus, they do not need an aerodynamic shape.
