I’m a recently retired engineer, and with time on my hands I started to try to learn more about some aspects of cosmology that had intrigued me for a long time. One thing led to another, and as I worked to get a deeper understanding of modern theories I encountered several places where the standard models and concepts appear to be flawed. I also frequently encountered good presentations and discussions on Physics Forums, and it looked like a great place to seek answers to some of my questions. However, after reading the policy on speculative discussions, it sounds like I wouldn’t be allowed to ask my questions, as they do challenge aspects of generally-accepted theory. Is that really the case?
