You are getting to the point AATW . If you did an experiment that proved earth to be a globe in your opinion then that experiment should be repeatable and predictive and doable by anyone with the means to do so. Then anyone can see that you are correct . That's the scientific method and how science advances - through experiment . Why do you need a peer review ?
Well, you need to do two things. Firstly you need to verify the method used. If you're doing observations of the horizon, say, over water and you haven't taken refraction into account then you may have drawn the wrong conclusions. I might well repeat your experiment and get the same results as you but if the method itself is flawed then the conclusion drawn from the results is still invalid.
And secondly yes, repeating the experiment can be part of peer review.
When Andrew Wiles finally proved Fermat's Last Theorum his paper was reviewed and a problem was found with it. He later fixed it but the point is the maths world didn't just take his word for it, like in science they checked his workings.
The heliocentric model was not introduced with any new data or experiment
It was introduced as a better explanation for the retrograde motion of planets. You're right in that it wasn't new information but as telescopes got better and observations more accurate it became clearer that this explanation better matched observations than the geocentric model.
We have never measured any curve
Just demonstrably not true. Plenty of photos and video of the globe earth from multiple sources and even a horizon line on a beach a few miles out to see is evidence of curve - a sharp line always indicates that either that's the end of the object or the object is changing angle so you can't see any more of it. A sharp horizon line, the distance to that horizon line increasing with altitude and things sinking behind that horizon lines are all evidence of a curve.
or detected any rotation
You might want to tell that to the Coriolis and Eotvos effects, Foucault pendulums and ring laser gyroscopes.
The weight of objects varying at different latitudes is evidence of rotation as are the the way star trails go in different directions at different latitudes.
TL;DR, the reason FE is not coherent and contains a lot of contradictory ideas is that you don't open up your work for peer review.
At best you might discuss your work within the FE community, but that is not proper peer review as that is made up of people who are not scientists. Peer review and cross-checking each other's work is a vital step in making progress.
