Just watched it - dear god, I can't believe people fall for such bullshit. It seems if you say things with enough assertion, people will believe it. (I suppose Trump and Boris are evidence of that).
A couple of blatant examples where he was talking crap- for example of course compasses don't work in the artic - that's where the magnetic north is, and compasses don't work next to magnets...
And why people don't go to the Arctic? Actually, they do - plenty of climbers/mountaineers go into the remotest regions. But there are massive issues of ownership of Arctic regions (it's is actually a complex and fascinating topic - well worth a look if you've got a moment.)
But most of his ideas were totally stupid - that American Government has created this conspiracy and that everyone at NASA is in on the hoax, and that all pictures are computer generated? Ridiculous. He couldn't even answer how it would benefit the government. And if we live in some sort of manufactured plasic bubble - then what's outside that bubble? It's stupid.
He never even mentions the stars - anyone can get proof that we live on a circular earth just by looking at the stars. Have a look at them now and again - you'll notice the Plough rotates slowly around the N.pole star. And Orion, closer to the horizon rotates even faster - as if we're spinning on an axis...
Even Aristotle in the 4th Century commented on the stars in relation to the shape of the earth. - what on earth would Aristotle gain from an 'American hoax' in the 20th Century?
Never mind basic, basic geographical features that prove the earth is round - like air currents and heat currents. Anyone who has done even a geography A level could disprove his ridiculous assumptions.
