Thanks for your review and comments Peter.
First, I would like to correct one misinterpretation; my essay included an "observation", and not an "accusation", regarding physicists not questioning the model when dealing with observational data which does not "fit" the accepted paradigm. I noticed a surprising number of papers on arXiv where the conclusion included a statement like "These observations do not fit the prevailing, accepted model", or something to that effect, and then just leaving it at that.
Secondly, regarding "scrape into consideration for a prize", for me this is not about winning an essay contest; it is irrelevant. My aim is to get these ideas out there for a critical review, by scientists far smarter than I. I don't expect members of the "establishment" to seriously consider my ideas or even waste their time reading the essay. However, I do hope that some young physicists, just starting their careers, and not wedded to the status quo, will take some of these ideas, explore them more thoroughly, and decide for themselves whether this alternative paradigm has any validity.
Thirdly, regarding the time frame. I think that 10 years for a change in thinking is wildly optimistic. General Relativity is now almost 100 years old, and yet cosmologists still stick with Newtonian gravity, where gravity is a "force" between objects, rather than the Einsteinian motion of matter through curved space, which gives the illusion of a force. One also has to be realistic, and realize that mainstream physicists have 20, 30, 40 year academic careers tied to preserving the status quo, and vigorously "defending" the Lambda CDM paradigm, so any change will not come either easily or quickly, especially coming from a non-physicist. One also has to avoid being bitter about rejection. After all, this is about ideas and not people. It is not about winning or losing, but about working together in a search for the "truth", whatever that happens to be.
Thanks again for your comments.
