That all depends on what people's mindsets are on who is in on it and who is basically duped by it.
Most people wouldn't have a clue what it is they're actually monitoring.
Half the world doing what?
It only requires a very small amount of people to carry this stuff off.
Of course. I'd guess there are plenty that has tried. But let's put you into that category you champion.
Let's bring this down to a small level.
You're at work and you find out your firm is duping the public. You're on fantastic wages and have a lovely home and family and car and watch and....well, you get the gist.
You decide to blow the whistle.
The owner is well respected and has important people in his/her pockets.
You decide to tell all and sundry about this and that.
What do you think will happen to you?
Do you think you'd keep your job?
Do you think your CV will be updated to add in your stint at the place which made you very comfortable?
Do you think you'll be cast aside as a bitter employee?
Maybe even cast aside as unstable.
Where's your next job and who will believe you?
Think about that on the small scale and then think about it on a larger scale.
I know, I know, it just can't happen, right?
Good actors? You don't need good actors and you don't need many.
And once again it never has, nor ever will be, for obvious reasons.
Using centuries to argue a point is basically not helping any global story.
It's a story absorbed by millions, not peer-reviewed for facts.
I have challenged it but I know most will never see that because, as you say, it's the status quo and recent historical adherence.
You don't need a penny to prove it's not a spinning globe.
Or a central and outer gradient.
To mimic a globe model exactly would be impossible, hence why I mentioned tweaking it all. I mention tweaking it all because it would need that to put Earth back to what the real potential of a map could be.
The globe is just a model and does not represent reality but it's told to be that and people simply go with it because they're shown videos and pictures and read stories of it supposedly being a spinning globe.
Why would people think any different when everything's on a plate for them?
You can swear as many times as you want to for me but it won't ever make your Earth a supposed spheroid that you supposedly live on.
When people use their own logical senses they will see the spinning globe and it's trimmings become more and more nonsensical as they age.
Absolutely and this is why alternate views are frowned upon. Bias at its best.
I agree this would likely be the case.
A judge and jury with a lawyer who has all the supposed evidence on silver platters. So their reasonable doubt is not in question to them. It's simply a followed belief system that will always win the day.
And that will prove what?
Do you know how they map the world to show it to be a globe?
Aye throw the water level away and go for something which is absolutely ridiculous and has to be explained using magic.
Water apparently curves over a big bulging spinning ball and magical mysteries keep it on.
Against what we actually see.
Sea level, water level.
I'm 100% comfortable with knowing what Earth is not and it is not a spinning globe.
I'm super comfortable with what I'm going with.
