describe it

It's a picture of some colors with an X in the center

When you stare at the X, the colors disappear

The Troxler-Effect

I've seen that before. what does that have to do with a flat-surfaced Earth.

When you think you're on a flat surface, it doesn't immediately mean it is flat

Because it's constantly the same feeling, it could also be the Troxler Effect

we didn't just think we are on a flat surface. we get that from experiments

observation is the first step in the scientific method

The same kind of experiments (sending people to space...) proves the earth is a globe

but the results have already been falsified

by identifying fraudulent data handling

Wouldn't it be a bit too expensive to organise space flights to just never reveal it's results?

no. it's cheaper

you collect $20 Billion/yr and don't have to do anything

What are they planning to do with the fact that the earth is flat/globe?

I don't understand your question

but you are jumping ahead anyway

If they keep behind the truth, it has to have a reason, right?

You've skipped some steps

@ChinaGirlNL hidden lands with hidden resources

When a detective shows up a crime scene, what is the first question asked?

does he/she ask "who did this? why did they do it?"

no

they ask "what?"

"What happened here?" i.e. they collect data

to understand what happened first. only then can they take the next step to ask who, why, how

So first understand the "what"

what is the nature of our world?

once you have confirmed it is flat surfaced, then you can start to ask "why the lie"

and who did it

Problem: I don't believe the earth is flat (nametag)

then it doesn't matter why they would lie. you don't believe they are

So I ask myself why a hypothetical lie would be made?

but that shouldn't be used to determine the shape of the earth

'Why' is the most interesting question to me

I have my own hypothesis. others here may have their own. regardless, it can't be answered scientifically.

Because it doesn't ask for a fact, which means the answers can be multiple things, much more interesting

so what's the point?

but none can be tested/proven

Exactly
