The title of this piece made me curious to read it. I am not really a sci-fi reader or writer. The closest to science fiction that I have gotten is time travel romance novels by Lynn Kurland and Jude Deveraux.
As much as I barely understood what you were saying there were a lot things I had heard of at some point in my life.
I appreciate you not stating a lot of scientific long words. You may have explained things in a scientific manner but it was in a language that someone like me could understand. I don't understand the gravity and anti-gravity part, or the membrane theory.
The explanation of the piece was complete enough to keep me guessing how all this pertains to life on the planet. It does not change anything about me just a new perspective on how the world works.
I don't think there's much you can improve upon especially since this is not area of expertise. There were no grammatical errors that I could find and all your words were spelled correctly.
Are you going to write about time travel next? I have heard people are coming close. Keep writing. This is a good piece.
