In my opinion, if we look at this as fact we're missing the whole point. It is not meant to be "Fact" or "Fiction". It is made to make us "Think". As first I thought it was real. Then I thought it was fake. Now I know it's both. It also blew my mind when some of the "facts' were revealed about the age of solar systems etc. Actually, this subject always blows my mind. Sometimes I feel amazingly lucky. Sometimes I feel like a complete victum of my own existance. So, exploring the possibilities of the Universe, I'm all for! By the way. Excellent production in most of the show. Very high quality and sometimes sooo good it's hard to tell which is which, I think it's brilliant.
