I cannot post here the links yet, but you can just search it up, there's so many links out there that will explain to you the theory.
Honestly, I don't believe in this theory but I found it interesting. You get my point?
I actually tried to write a short story about this because I found it interesting. But I don't know what ways can I improve my story about this fiction.
Things to remember: I am writing this story not as a true to world story, but a plain fiction. So that would mean I would include powers, uncommon strength, etc. I would not take the whole theory itself, but just some of it. (I mean, just the hollow earth but i would not include the partly angels in the original theory)
So, I posted this not to ask about your opinions if this is pretty cool or what, but I just want to know what points should I consider in making a fictional story. Much more better if you will include some of your stories, already made or not, (if you have one), so I will know tips from more advanced writers since I am just a beginner and this is my first fictional story. Thanks guys!
