Where is planet x?

[wratched]

Tom van Flandern is something of a kook; he believes in a lot of things that "normal" scientists don't believe in any more. There is, as far as I know, and I have researched it quite extensively, no evidence of sedimentary rock in the asteroid belt.

No, in fact, the asteroid belt is mostly sedimentary/metal rock like objects unlike the Kuiper belt which is mostly frozen water, ammonia, and methane. And the Asteroid belt is mostly likely a destroyed planet.

if there is not enough water present in our solar system to fill Earths oceans, how can the current ideas that Mars, Europa, other planets and moons have geological features caused by water erosion. Perhaps we should be looking more carefully at the hydrogen oxygen binding process for the answers, expanding earth anyone?

[landru79]

perhaps i'm wrong but there aren't sedimentary rocks in the asteroids belt too. The place where runs the belt is a bad place to appear a normal planet. Jupiter is too near. ;-)

Sorry I'm referring to the asteroid belt that runs through our solar system. I must have the two confused.

[landru79]

there aren't sedimentary rocks on kuiper belt.

[jlettis]

I think Thomas Van Flandern has it correct with exploded planet,the sedimentary rocks are an obvious clue, they don't form so well in space.

[landru79]

a non-borned planet better

[jlettis]

Kuiper belt= Exploded planet
