Planet X orbit
This site also talks on how the Sumerians knew and predicted this
what do you think ?
I think that the people who put up the site don't know anything about physics OR the Sumerians.
Now... let me explain.
If a planet hit the Earth, it wouldn't "split in two." It would demolish both planets. Think of two raw eggs hitting each other.
Astronomical bodies that hit the Earth (meteorites to asteroids to planets, maybe) do one of two things: They smash into the Earth (damaging
themselves or obliterating themselves) or they obliterate it. The Earth's gravitational well means that if things get close enough to hit the
planet, they don't run away (though very small objects can "skip" off the atmosphere. We're talking objects a few yards in length or less.)
The Sumerians never heard of the planet Nibiru. We do have their astronomical tables and observations of their astronomers. They only knew the
planets Mercury through Saturn.
Their math wasn't good enough (and their instruments weren't good enough) to calculate orbits of rarely seen objects (you need calculus to do this,
and they didn't have calculus.
The website author hasn't done their geology homework, either. They have a nice animation of Pangaea that splits to form our modern continents...
but they don't understand plate drift, erosion, mountain building, the impact of weather, glaciation and so forth. The simple animation doesn't
show that pieces of the crust slide UNDER other pieces or show how erosion and glaciers sculpt and erode the land.
They have a nice selection of astrophysics papers -- but they don't understand the papers they present. Scientists have long believed there were
other bodies beyond Pluto (and we've found them, including Sedna and the more recent "Xena") -- BUT that they were in stable orbits and never come
into the inner solar system. So the "planet X" in the science papers has nothing to do with the imaginary "Nibiru."
