I've been looking into the matter, and I'm convinced the Space walk wasn't a hoax.
I think just because they slipped on one pre-written report it doesn't mean the thing didn't happen. With the high profile of the mission it's natural to think that they carefully scripted everything that was going to be said ahead of time. As you can see on my montage, the mission commander reads from a script after the space walk.
Apparently, the media in Taiwan, a country not particularly friendly towards China, declared the Space walk a hoax right from the beginning. The reasons they gave were the usual ones:
1. There's no stars in the video.
2. The flag waves around as if being blown in all directions by wind.
3. The rapid movement of the Taikonaut. The suit should slow him down.
4. China fears America's scientific genius, so they made a fake video.
In addition, some bloggers have suggested:
a. That the Space walk is filmed underwater due to visible “bubbles” in the footage, or possibly during a weightless flight.
Let's look at these:
The no-stars claim has also been used by the conspiracy theorists who think the Apollo missions were a fake. The thing is that when it's daytime, it's so bright that your eyes will iris down and you won't be able to see the stars. This goes for daytime on the Moon, or being on the day side of Earth in orbit.
It looks like there’s a breeze blowing around the flag. Mythbusters have already debunked this myth. They put an exact copy of the Apollo mission flag into a vacuum tank to see if they could replicate the effect. They did. There’s no air pressure in Space so small wrist movements will make the flag go all over the place.
Rapid movements? The same thing that goes for the flag applies here, no air pressure. Also, if it was filmed underwater, wouldn’t that definitely slow him down?
China fears Science America? I doubt it. I watched a clip from Space.com where they had an American scientist on commenting the Chinese Space walk. He said young people in America shun getting jobs in science because it's considered to be too hard, and it's easy to get a good job in the service industry. Money is more attractive than contributing to science.
The "bubbles" that can be seen in the Space walk footage suggests it's filmed underwater. But divers say that bubbles in water don't move like that. In water, bubbles move slowly in the beginning and then gain momentum. Also, the exact same phenomenum can be seen in the footage from America's first spacewalk, the Gemini mission, where they can be seen frequently moving in all directions.
If the weightless flight theory was true then they would need a plane big enough to fit that whole set. Also, during those flights you are weightless for about 30 seconds, no more. The Taikonauts can be seen for several minutes at a time in weightlessness.
I’ll wrap this up by quoting the scientist who commented on the Space walk: "I believe it and I'm jealous"
