Since a lot of information is passed left and right and the internet exists, how is one with only basic physics knowledge suppose to know what is true and what isn't? Obviously some 'crackpots' make it obvious they are wrong when they get even the most basic ideas wrong (like someone saying you can go >c is you go really fast and fire off a photon or something similar) but there are other instances where you don't really know at the basic level. I've seen book recommendations and non-recommendations and i wonder how one differentiates between saying a book is good vs. crap besides taking someones word for it. I mean you can't exactly go out and conduct a plethora of experiments at the basic level... so your inevitably relying on peoples ideas. Does anyone understand what I'm saying? Its hard to think one way because people tell you its correct when we're talking about things you don't have a lot of real world experience with.
