What Scientific explanation?

Answer 1

Explanations must be Consistent.

The explanation for one set of phenomena cannot contradict the explanation for other sets of phenomena.

If explanations are inconsistent, they must be rectified or abandoned.

Explanations must be Testable.

Explanations must be examined in

laboratories, in nature, in the field or through the study of past events and

must be capable of shown to be incorrect. If they are incorrect they must

be changed or abandoned.

Preferred Explanations should be Elegant (Simple).

Explanations that require the invention of the fewest "missing pieces" have the greatest reliability. Explanations cannot include pieces that are either inconsistent

with what is already known or that are untestable.
