What is the scientific process?

Explanation:

The scientific process is supposed to be something like ...

At any point, the observations and theories can be published for critique by other observers, experimenters, and scientists.

The theory should be sufficiently defined so that it is possible to differentiate a relevant experiment or observation from one that is irrelevant. Similarly, every effort should be made to separate causality from correlation, and to identify or rule out alternate causes or additional causes from the one(s) theorized. Experiments should be sufficiently well-defined so that they can be reproduced.
