illuminati signs on america's got talent 2011

We are a little behind with americas got talent and I've just finished watching the first live show aired originally in july 2011. One of the acts was called Squonk opera. I'm gonna try to put the you tube video up of the original broadcast but i'm pretty new to this so...
I'm not very clued up on signs and symbols but maybe you can enlighten me. However towards the end of the clip there is a reference to betelgeuse and our world become a ball of red and black flame and from this a new world is born. I know you guys are on top with this shit and what i'm posting is probably old news but I would love to hear what you think.
