There are 3 voids known to humans. Subatomic, dealing with irrationable and random movement, Relative, doing with the blanket pattern forming space, and membrane or brane, doing with the multaple universes. Everything fits togather in these subcatagories of the universal theory; which we haven't found the brainpower to create. It is also all to obvious that there is outher life out there, I mean, we found bcateria on Mars, that is life just in our solar system! About "Planet X"; I put 79% or more of my bet that it is there.
