I just wanted to complete the quote from DuckDodgers for you, and add a little emphasis:
...you could ignore every single RE post and work solely on FET if you so chose to. We are actually helping you identify the holes in your theory.
Take bendy light for example. I put a bit of work into figuring out how much it would have to bend both up/down and left/right. You can find all that info (and the related discussion of course) in
this thread. This should be of great help for someone to work out a
proper formula and constant to describe the behaviour of bendy light. Of course, without bendy light, FET just doesn't work at all, it's just too easy to prove wrong.
Back on topic though, gravity is the "explanation of best fit" when it comes to explaining why things fall to earth when dropped. It doesn't have to mean the earth is round, it just means it doesn't have to be accelerating upward at a rate of ~9.81ms
-2 (which is totally implausible, especially with variances in the acceleration due to gravity being so well known, and easily measured).
Use the feedback you get to refine your theories into something more coherent and plausible, just like real scientists do.
