how do I know I'm getting the best answers to my questions?
Firstly, that depends on defining "best". I am quite happy with Start Page (i.e. Google without the record/detail retention) for simple matters. But when looking up more complex matters - such as today, I was checking the spacing of shell-layered parallel universes separated by energy grids, and whether given the consequent continuous pulse theory of universe formation, there ever could to be said that there had been (or is or could be) a start point in time, and if so how would one define it (i.e. against which subjective or objective parameters) - then I go to the scientific search engines.
