scifi levels - looking for link of article

Can anyone help me? I remember having read an article somewhere on the internet about the different stages of science fiction / free thinkers. I've tried searching, but to no avail. I only know that there were four stages and that the last, fourth category was about science fiction thinkers who think really far into the future..how earth, humanity, technology etc will be in 10000+ years. anyone know what I'm talking about? :o

Thank you for so perfectly illustrating my point.

You don't seem to understand what the word "theory" means. They're not "just theories". They are concrete models for describing the universe, for which there is an overwhelming amount of scientific evidence. Devices like inertial dampers and subspace communicators violate the most fundamental laws of the universe, namely conservation of energy and causality; if some small device can simply set these laws aside, the entire field of science falls apart at the seams.

I sure hope you're not a scifi writer.
