a) There are multiple foreign nations who have travelled to space - many of whom are openly hostile to the USA. None of them blabbed?
During the cold war the US expressed open skepticism against the Soviet Space Program, and vice-versa.
Their skepticism was about the EXTENT of the opposition's capabilities - not about whether they could orbit a satellite or put a man into space...which is why (for example) the Soviets put a radio transmitter onto Sputnik that was tuned to a frequency that any amateur radio ham could pick up. I vividly recall my father (who repaired TV's and radios for a living) spending all night building a 20MHz radio receiver so that his three year old son (me!) could listen in on the sounds from it every 90 minutes as it rose above the horizon and tracked across the sky in a matter of a minute or two. At that young age, I couldn't understand why it was important - but my Father told me "This is the most important thing you'll ever hear!" and it turns out to be pretty much my first memory. As it turns out, he was probably wrong about the significance of it...but he was no fool.
b) There are multiple non-government agencies (SpaceX, for example) who would have to have been in collusion. None of them blabbed?
NASA is actually composed entirely of non-governmental agencies called government contractors, public-private arms of the state which operate within the government's secure realms.
Actually, NASA has over 17,000 employees of it's own - they are NOT entirely composed of NGA's. Also, I've worked on projects for NASA (I built simulators to train Space Shuttle pilots and the people who operate the Canadian robot arm on the ISS. I've met and worked with astronauts who've been to the ISS...and they don't seem to me to be at all dishonest people.
c) Not one "death bed" confession from an astronaut? Really? Not a single one?
Buzz Aldrin's entire personal and professional life revolves around the fact that he was an Apollo astronaut. It has brought him fame and fortune and he has traveled around the country inspiring adults and children alike. Do you really think he would admit that he was a phoney?
Also, when people are sick they generally believe that they will pull out of it.
Deathbed confessions are quite common - and generally turn out to be true. See:
https://en.wikipedia.org/wiki/Deathbed_confessionYour explanation might explain why SOME people do not confess - but it cannot remotely explain why not a single one of the hundreds of thousands of people who would have had knowledge of this supposed conspiracy ever admitted it.
d) What about all of those astronomers - they'd all have to be in on it. Nobody blabbed?
Astronomers merely observe the sky and interpret. They are not scientists who put their subject matter under controlled conditions to come to the truth of a matter --they can't. Astronomy is not a real science. Astronomers are fake scientists.
That's not a very nice thing to say! Wow!
Anyway - what you say is untrue. Astronomers (some of my best friends are astronomers) do indeed do controlled experiments. For example, the idea that the expansion of the universe results in a measurable red-shift in starlight. That was a "hypothesis" - which was then tested by performing the experiment of looking at the spectra of light from many stars who's distance could be estimated by other means. When the degree of red shift was found to accurately match the theoretical values - the hypothesis was proven and "The Hubble Hypothesis" became "Hubbles' Law". Yes, they are scientists - yes, they do experiments. No - they are not idiots. No, not a single one of them believes in the Flat Earth and if they are conspiracists then not a single one of them has ever blabbed about it.
e) What about all of the people who build and sell GPS equipment, without satellites in orbit, GPS can't work the way it's claimed - but the people who write the software for these things would also have to be a part of the conspiracy.
The military built the GPS satellites and the military is publishing the spec.
Yes - but what about the software engineers who write the software to decode the signals from these radio sources and the hardware designers at places like Apple, Sony? They have to write software that calculates positions of satellites - to assume that this is possible without understanding that the Earth is round is...beyond naive. Honestly - either all of those people are in on the conspiracy - or there is no conspiracy.
f) Ditto satellite TV companies.
Do you really think that Dish network is building and launching their own satellites single handedly?
Again, you're assuming that once the satellite is launched - that's the end of the story. Of course it isn't. Every one of those Dish Network electronics packs is running software written by someone who doesn't work for NASA or any of the launch companies that alters the dipole on the satellite disk to track the signal. Really - the business of making and selling satellite TV receivers REQUIRES that you know how the satellites are placed - and if the world is really flat then an awful lot of people at Dish Network are "in on the conspiracy". It's naive to assume otherwise.
g) All of those ships, drones and aircraft that are claimed to be patrolling The Great Ice Barrier have to be in on the conspiracy - so do the people who build those ships, the people who supply them, the people who crew and repair them. So do all of the countries who have navies down there who'd have spotted them. So do all of the air-traffic control people who watch these aircraft land and take off in huge numbers.
Who claimed that the wall was guarded? Why are you making stuff up?
Many of your fellow FE'ers believe that. I guess you personally do not - but if you don't, you have to explain how it is that antarctic explorers and the people who live for extended periods at the south pole are "in on the conspiracy".
h) Navigation by the stars can't work the same way in FE as it does in RE. But sailing ships going back to the 1600's used this navigation technique...and their sailors wrote manuals about it - there are copious books on the subject. Every commercial shipping company and every navy in the world would have had to be a part of the conspiracy.
Celestial navigation works by looking at the North Star and gauging where East and West are based on that. For the South it involves finding the Southern Cross.
Again, your understanding of the very basics here is sadly lacking for someone who claims to be an expert in FET. Navigation is a hell of a lot more than knowing which direction you're facing (which is really all you'd know from seeing which direction Polaris is in). It's about calculating your latitude and longitude - from stellar, solar and lunar position observations which allow you to deduce the local time and therefore your position.
Those calculations - in fact the very way you measure the things that go into those calculations - are based on the presumption that the earth is an approximate sphere and that it rotates every 24 hours and that the sun is a VERY long way away so it's parallax may be ignored.
Imagining navigation to be as simple as you say is ridiculous. Really - go learn some of the very BASIC facts of how ships navigated before GPS and other radio navigation aids before saying this kind of nonsense.
Really Tom - for someone who claims to be an expert (possibly THE expert) on FET, you really should get to understand the counter arguments.
I strongly recommend
https://en.wikipedia.org/wiki/Celestial_navigation to understand how exactly ships navigated before around 1900. If you take the time to understand what this is saying - then you'll realise that the technique described cannot possibly work with FET being the way it is claimed to be.
So, again, you're left with literally MILLIONS of people today, and going back to the 1600's and earlier who are a part of this conspiracy - or the earth is round.
I also recommend the excellent book "Latitude: The True Story of a Lone Genius Who Solved the Greatest Scientific Problem of His Time" by Dava Sobel - which explains the great lengths that people went to in order to navigate at sea. It's a great read...and leaves an awful lot for you FE'ers to explain.
