Having read a few of the posts concerning the book "Return of Planet X" I would say that the critiques of this book exude fear and the unwillingness to perhaps come to terms with the fact that our earth could very well go through some drastic changes and could very well fall to pieces. As a matter of fact there is excellent Science and astronomy in this book. Facts are a stubborn thing and it is unfortunate that there are many who refuse to accept the Truth. There is a thing called common sense, logic and a combination of much circumstantial evidence which can help in finding the Truth. The other Option is seeing is believing!!! Yes there are those who can say they have heard the end of the world story many times in the past and they are still here!! This in no way means that the world will not end in some future time. I believe that there is much evidence to support the fact that 2012 will be significant to our earth..in fact, the Book "The Return of Planet X" will be shown to have much validity, and one would be wise to TAKE HEED of the words and message therein!!!
