Many of us have observed the world to be an oblate spheroid, others have observed that the Earth is a disk. We should be able to use the scientific method determin which theory is stronger, or invalidate one theory or the other.
1. Observation and description of a phenomenon or group of phenomena.
2. Formulation of an hypothesis to explain the phenomena. In physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation.
3. Use of the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations.
4. Performance of experimental tests of the predictions by several independent experimenters and properly performed experiments.
Items 1, 2 & 3 have been done on this board to exhaustion, does anybody have any ideas for inexpensive experiments that could be conducted by individuals in support of either theory?
