A bubble emerged in "space" and accelerated upwards, just like an air-bubble accelerating to the top of a pool of water. What part of this evidence do you not understand?
In a vacuum, an object would not away like in the video.
Do tell us how you determined that it was a bubble. Do tell us how you eliminated other forms of acceleration. Do tell us how you measured the acceleration and whether it's in line with your hypothesis.
Then don't forget you still have to show the
intent to defraud. You haven't demonstrated that the Chinese Government even posted this video. You're not even in the ballpark to show that this is, in your words, "Conclusive proof the chinese [sic] space agency has faked spacewalks".
As usual, FET has only half-baked ideas and evidence. Another FET epic fail. It's just like Carpenter's proof that world is flat because the HMS Challenger's entire voyage including to and from England and over-wintering in South America over three years means that the distance around Antarctica must be too great for the Earth to be a sphere. What's next? Maybe we'll hear how the fairies build the nexus rings? We've already heard that some consider the phases of the Moon to be caused by, oh get this!, biology. The Moon plants grow and die off producing the Moon's phase.
