Let's say you think you have a good idea, but you're too scared to publish because if you're wrong you can ruin your reputation, how do you go about getting feed back? I have presented the idea in the link below https://www.physicsforums.com/showthread.php?t=399767 to a couple colleagues and they find it cute and insightful. Additionally, there's so much literature, I could spend years doing background research, and still not figure out if some one published the same thing in some obscure place. Despite the fact I'm about to get my PhD, I still could use the guidance of a mentor. I feel like this is a sign that I should quit research.
