I do not understand what you are trying to say. You said that we can find evidence for what you observe directly, but we have observed this phenomenon! We've measured it using highly sophisticated equipment and we've proved that the area around hudson bay has less average gravity than the rest of the earth. None of you have provided any verifiable claims or evidence to counter this, because it clearly does not fit with the FE model, but as I explained in the first post, it does fit with the RE model
