As I understand, science requires tools of measurement, procedures for testing, and working theories that can be tested to gather data concerning the results. A speculation is an idea that has not formed into something that can be tested, but has the possibility of being polished into a testable theory in some cases. Pseudo-science is composed of material that can not be tested, and ranges often into the spectrum of wild speculations with no grounding for any verification. Can anyone elaborate on this if it needs to be elaborated? Thanks.
