Then and now, if you had less education, or if you are young, you are not really going to be accepted into the scientific world. The example of the letter to the Royal Society, but no reply

it might not be that; they get inundated with ideas and proposals from the public most being way out and separating them out and assessing can take a lot of time.
Have you shown us a copy of what you sent? I saw your PowerPoint
I also saw a post on hearing that I am going to reply to.
