Actually the most popular theory of planet formation for the inner solar system holds that there were somewhere around 20 rocky planets of various
shapes and sizes at the very beginning, and while still gathering matter and cooling, we had a lot of impacts and near misses resulting in planets
obliterating each other (giving other planets yet more material to aquire), changing of orbits that led to a fall into the sun, or flung out of our
Note how I said "most popular theory", as in truth, even with the most modern super computers to run simulations, without a time machine to go back
and look, we'll never really truly know.
If we can some day see in greater detail other systems forming, it will give us even better data to work with, but again, while things might follow a
trend, it won't prove exactly how our system formed.
If we look at Sitchin's theory, we have a planet that impacted with another planet that had formed between Mars and Jupiter.
Okay, that's not far fetched, as again, the most popular theory says there were many planets colliding then. So I can buy that.
The impact split this planet in half.
This is a little hard to swallow, but not completely impossible. It would depend on Nibiru's size, Tiamat's size, angle of impact, velocity, etc.
Many computer models show that rocky planets tend to obliterate each other on impact, with one possibly retaining enough material to reform. The
Earth's Moon impact theory has the Mars sized planet and Earth doing just that, but it had to hit at just the right angle too.
Then Nibiru came around and impacted the remains again, causing one half to move away and end up in Earth's orbit, and actually became the Earth.
Now this step is much more hard to swallow. Nibiru hitting a planet split it in two, and then the next time it impacted it just caused one half to
move and later it became Earth. If you think about the forces involved, if it broke the first planet in half, I'd hate to think of what it would do
smashing into that half again. To me it would be obliterated or added to Nibiru's mass.
Then here comes Nibiru again, only this time it's one of it's moons that hits the other half of the original Tiamat and that shatters it so that it
becomes what is now the asteroid belt between Mars and Jupiter.
That part boggles the mind. Nibiru itself only splits Tiamat in 2 pieces, then hits again and only pushes on piece into Earth orbit, yet on the 3rd
time around, a much smaller moon is able to smash the rest of Tiamat into all the pieces of the Asteroid belt.
There are a lot of problems and unknowns here with this idea. First, Nibiru's size. It would have to have been at least 3 times or more massive than
Earth (since Earth is 1/2 of Tiamat according to this theory, and Nibiru was able to break it into 2, yet remain pretty much intact), not impossible
of course, but would be a requirement.
Next is the formation of 1/2 of Tiamat into the Earth. The 2nd collision somehow sent that mass into Earth's current orbit (which is a very stable
orbit around the sun......if I were a betting man the odds against that are so high I'd call anyone else a fool for betting on it).
Then there is the last half of Tiamat being shattered by one of Nibiru's moons, forming the Asteroid bet. The problem with that as you pointed out
is: the amount of material in the asteroid belt if put together is only 4% of our moon. That's tiny, and wouldn't equate to 1/2 of Tiamat which
would be close to Earth's mass of course.
You mentioned that most of the material might have been flung out from this shattering, and might be an answer, except: it was Nibiru's moon that did
this shattering, and Nibiru itself was only able to split Tiamat in half and bounce 1/2 to Earth orbit, so that just doesn't add up I'm afraid.
Most modern theories hold that the asteroid belt formed because gravitational perturbations from Jupiter kept anything from forming there. The other
reason that many accept that theory is because of the composition of the asteroids in the belt: they are made up a many different compositons, meaning
that they didn't all come from one planet.
Of course if Nibiru is a Jupiter +4 sized planet or brown dwarf none of Sitchin's theory would hold up either. A gas giant that size (or worse, a
brown dwarf) would have swallowed Tiamat whole, not split it in two.
So does this destroy Nibiru? Well I think it makes Sitchin's theories wrong. Is there some rogue planet out there?
I'm open to suggestions and speculation (which is fun), but not Sitchin Dogma.
