You would know best.
I would know best how to do the impossible? You flatter me, but no, I'm not a miracle-worker.
Given that you seem to be certain of those groups which do not belong in the conspiracy
And since when is this a given, exactly? When have I spoken with this supposed certainty?
I figured by logical extension that you would most likely know who does rightly belong in it.
If your "logical" extensions lead to introducing unhelpful strawmen, you should consider using either more logic, or less logic. I'm not sure which would work better.
We should at least be able to lock down a few obvious players, right? NASA being the prime one.
Why would NASA be "the prime one"? You seem to know something, but you're reluctant to share it.
Would any other agencies of US government have to be involved?
Why are you discussing agencies when you should be discussing individuals?
If all space travel is faked, wouldn't all 72 existing space agencies have to be knowingly complicit perpetrators in the hoax?
Given that most of them do not claim to perform the extraordinary feats you attribute to them, there's no need for them to be perpetrators of anything at all.
I'm talking about ships and planes getting lost because the RE-map is supposedly wrong. If the RE-map is wrong, how come ships and planes still find their course?
What makes you think that a specific projection of the Earth can't be used for navigation?
I'm talking about satellites not being where they are supposed to be. If RE wrong, why are the satellites where RE claims they should be?
What makes you think a specific projection of the Earth can't be used for location?
I'm talking about stars and planets not being where they are supposed to be. If RE is wrong, why are planets and stars where RE claims that they should be?
See above.
I'm talking about extraterrestrial radiation. How come that particle-physicists can detect stellar neutrinos coming THROUGH Earth from the direction where the Sun should be according to the RE-model?
Electromagnetic acceleration.
I'm talking about distances and angles not fitting to the official maps when a cartographer makes a new map from measurements. Why do his measurements fit to a RE-map???
An "interesting" allegation, but it's been discussed to death in other threads. I recommend the search function.
If Earth were flat and then there would be thousands of instances each day across all of industry and research where the measurements do not match the official numbers. And yet there is not one corporation and not one scientist who complains that the official numbers are wrong.
If Earth were flat, then all the calculations based on the RE-model would be wrong and would lead to thousands of accidents and incidents every single day. How do you cover up the shape of Earth when thousands of people compare the official numbers to real-life every single day as part of their job?

You have yet to substantiate any of this. So far, your claims rely on RET being internally inconsistent rather than "wrong". I already told you that this is (for the most part) not the case, and highlighted the fault in your reasoning. Restating your reasoning, shockingly, did not advance your point.
Au contraire. The conspiracy is actually very well defined.
Is it? Let's hear it.
- The aim of the conspiracy is to control/fake information about the shape of Earth and/or space-travel.
This flies in the face of every single conspiracy proponent's claims, so I'm going to venture a guess here and say that's false. If you want to propose your own conspiracy in order to then explain how wrong it is, please refrain from doing so in the upper fora.
- They do this by involving all the people that would be necessary for doing so.
Congratulations - the crux of your argument is a truism. This is getting better and better.
- The conspiracy has successfully fooled hundreds of thousands of corporate professionals and scientists every single day for decades without any slip-up ever.
I already pointed out that slip-ups are relatively common. Once again, if you want to make up your own argument and then disprove it, I'll be asking you to take this elsewhere. Metabunk, perhaps?
- No member of the conspiracy has ever stepped forward and exposed them. In decades.
And now you've added a lie. Matt Boylan/Math Powerland and Thomas Baron would be very sad to hear that they never existed.
- No member of the conspiracy has ever lost control of sensitive information. In decades.
Other than the missing Apollo 11 tapes, you mean? I'm going to have to ask you to refrain from lying.
- Nobody has ever managed to infiltrate them or find them or identify one single person who's a member. In decades.
See above.
So, we have an all-powerful entity
Which is not all-powerful, nor powerful at all
that must exist
Except for repeated claims that it may well not exist
but you cannot prove that it exists
Indeed - it would be a bit strange of me to prove something I don't believe to be true
Funny. That sounds exactly like religion.
Indeed - your description of the supposed conspiracy, together with your willful misrepresentations and blatant omission of facts when they don't suit your narrative really does sound religious in nature. There's a reason I repeatedly called you a RE zealot, and I'm so glad you chose to document it here in such great detail!
