Although parallax IS a troll and cannot back up these claims with ANY evidence. Just a thought to bear in mind....
As far as I see he is referring you to Earth Not a Globe for most of what he says. Why not read it if you are so curious about what Rowbotham bases his conclusions on?
I assume you're talking about this:
https://en.wikipedia.org/wiki/Bedford_Level_experiment
Conclusions based on 180 years old experiments, recognized as flawed, corrected two years later (that is one (1) year after the coronation of Queen Victoria) and utterly, utterly debunked not only by modern science, but also by the ancient Greek. Why do you believe that Rowbotham was right?
Yes. Dr Rowbotham hasn't been debunked at all, the people that 'debunked' him made flaws in their experiments so produced incorrect results. I trust Dr Rowbothams work.
Y'know, Parallax, you need to step back and take a look at those experiments. Properly.
You're stating they are flawless, and absolute, and the people 'debunking' him are the ones who are wrong.
Rowbotham isn't perfect, my dude, he's a human such as you or I.
Finish following this fella and his fraudulent findings, and frankly, flake from this faker's flamboyant falsehoods.
The fool's findings are far from fact.
Also, if we're frequently fabricating the finding that flat fellas are false and foolish, 'troll' is false, as that's for flapjacks who feign flagrantly and find fun in fashioning folks' frustration.
