“I have theories” is great, everyone should have theories and ideas.

But if you can’t connect them to understood, known physics and systems that have been demonstrated over and over again for centuries, you’re not really contributing anything.

“I have ideas for a really cool race car shape. I don’t know anything about formula 1, I just have this neat idea. Why won’t professional teams who demonstrate their efforts daily take my design seriously?”

Go to school, educate yourself with online courses, read every possible criticism or attack on theory, be your own worst critic and THEN if it survives knowledge and critique, you have a chance of being seen and noticed. This isn’t about “encouragement” or “making someone feel better” and it’s certainly not a plot by Big Science to keep the little man down, this is just how the process works and why you have phones and video games and soda dispensers.
