I just explained what this theory says and put some photos and videos.
BTW you can check the "We are happy at CERN" video and see that the photogram is authentic.
About youtube videos, they're just users saying what they think, which may be true or false.
I also said I'm skeptical, but I don't own the truth, personally.
Do your own research and decide what is true and what is false, for you :)
