Hello Itchy.
You still haven't told me how you think space travel could be real on a flat Earth, that makes no sense at all to me.
Glad you asked that, it relates to one of my recent discoveries.
Two weeks ago I went to a talk on UFOs. I'm not a UFO believer, but the talk was near my home, so I thought I would go along just out of interest. The talk was awful, but a guy there said he was a university cosmology post-grad researcher. I got to talk with him after. Of course, he didn't believe in UFOs either, but he said he liked to expose "bad science".
I explained to him that I had doubts about some claimed achievements in space, expecting him to call me a nut and walk away, but get this; he smiled at me and said that it's well known in academic circles that most space missions have been nothing more than cold war propaganda. Basically both the US and Soviets started exaggerating their achievements and the whole thing snowballed out of control. That's why progress seems to have stopped; since the end of the cold war the propaganda has lessened, and today's claims are more in line with reality.
The truth is that we can launch satellites and probes, but that's about it.
