I read the article out of curiosity and noticed he didn't express any specific reasons he doubted the moon landings. Some people point to the craft that landed on the moon. I doesn't look like something that would be safe. I would be reluctant to risk my life in such a tiny thing with thin walls.
I am not expressing doubt myself. I do wonder about the solar and cosmic radiation issue though. The Earth's magnetic field offers protection from space radiation, so I am wondering if the mission was timed so the Earth was between the sun and moon. From what I understand, if it was the other way around the moon would not have any protection from the Earths MF.
Solar and cosmic radiation is a problem for manned missions to Mars. Finding a light weight solution is difficult. Lead is heavy.
I'm convinced they only do it for publicity. They are playing the media. He'll come out in a few months and say "Just kidding..... but maybe not." It'll get him a few more millions towards his next shoe deal.
No I believe that, as a celebrity athlete, Stephen Curry said this to increase his name recognition. The more people that know who he is, the more money he gets for endorsement deals.
