writersoul,
May I recommend the following book:
The Structure of Scientific Revolutions by Thomas S. Kuhn
I do not mean to be offensive so please take this the right way. Your description of a “scientific theory” is simplistic. It doesn’t take into account the vast differences between scientific fields (in terms of veritability) or scientific intertia (or dogmatism). Read Kuhn, I suspect it will change the way you think about science.
