The Tiamat Collision

The Battle is 3D: Tiamat on her circular orbit beyond Mars, Nibiru coming in on its 3,600-year retrograde ellipse with its perihelion on that orbit, the satellite that hits, and the time scrubbed from days before to forty years after. After the hit the remnant leaves on its new ellipse, which is seen to come back to the point of impact; the lower half stays where she was and shears into a ring by Kepler alone. Zoom in and the bodies are spheres at true scale: Tiamat, Kingu, the incoming satellite, Nibiru passing sixty radii out.

The Halves stands every mass in the story on one logarithmic ruler: Earth's oceans, Ceres, the measured belt, the Kuiper belt, the Moon, her ten other moons, Mars, the satellite that moves her, Earth, her lower half as the book has it, the Oort cloud's range, Tiamat whole, Nibiru. The upper half's share is a dial; 'two parts' is half by default, and Lynn's 'size of Uranus' is a preset.

The Move is the impulse: the single-impulse orbit seen from above, with the point where the second burn would have to be paid; and the impactor curve, largest remnant and kick delivered against impactor mass, with the dialled satellite, the one that halves her, Mars and the Moon marked. The inclination dial flips the story's sign: prograde, the winds come from behind and push her outward.

The Moon maps Kingu's leash, survival by distance and kick direction, with Tiamat's Roche limit and the Moon's orbit today drawn across it, and sets three measured rulers beside it: oxygen isotopes, core fractions, and ages. The File runs eleven cards, the words first, then the arithmetic, then two verdicts at equal size.

This site's culture wing carries a source note on The Anunnaki Chronicles that lays out Sitchin's scenario in seven rings, and the first ring is this battle. The solar system held 'the Sun and only nine other planets' (p. 105); Tiamat, 'the Watery Monster', was 'beyond Mars' (pp. 99, 115); Marduk, which is Nibiru, came in retrograde with seven satellites, 'the winds' (pp. 105, 109). On the first pass 'it was the satellites of Marduk that smashed into Tiamat, and not Marduk himself' (p. 110), and she was left 'fissured and lifeless' (p. 111); ten of her moons became retrograde comets (p. 112). On the second, 'Marduk himself now hit the defeated planet, splitting Tiamat in two', the North Wind 'crashed into the separated half' and 'carried this part, destined to become Earth, to an orbit where no planet had been orbiting before' (p. 113), 'nearer the Sun' (p. 120); Kingu was 'pulled along' as the Moon (p. 119); the lower half, 'on the second orbit', was smashed and 'hammered to become a bracelet', the asteroid belt (pp. 113-114). 'Some four billion years ago' (pp. 173, 340). Neither book gives a mass, a speed, an angle or an energy for any of it. This bench supplies the arithmetic the book never did.

It also follows the note on The Anunnaki Connection, where Heather Lynn reports a different version: Tiamat 'between Mars and Jupiter about the size of Uranus' (Lynn p. 42), and a Moon that is either 'one of Nibiru's moons' captured by Earth (Lynn p. 21) or 'another moon of Tiamat' (Lynn p. 42), never Kingu; the bench makes Uranus's mass a preset. It follows INST-70, the Nibiru orbit bench: that bench read Nibiru's size and inclination from the same book, and this one borrows them for the closing speed and puts its perihelion on Tiamat's orbit; the one-screen ledger in that bench's Battle view is opened out here into three. And it follows INST-71, the Gold Shield, the same scenario's motive. As ever, the answer is not presupposed. A planet struck off its orbit by another's satellite is a real kind of event; a giant impact making the Moon is the mainstream account. The bench writes those down, and then the masses, the impulse, the geometry and the Moon's three rulers.

Everything on the bench is arithmetic on the book's sequence and on published values: two-body mechanics for the orbits and the impulse, momentum for the impactor, a published scaling law for the break, the leash from energy and angular momentum. A script that ships with the site re-derives every displayed number before the build passes, the ones the book gave and the ones it never did.

u² = v_T² + v_N² − 2v_Tv_N cos i · Δv = v_T − √(2GM☉q/(a₀(a₀+q))) · Δv = m·u/(M+m) + 2GM_N/(b·u) · Q_R = ½μv_i²/M_tot vs Q*_RD = c*(4/5)πρ₁GR_C1² · M_lr/M_tot = 1 − Q_R/2Q*_RD · bound iff |v_orb − Δv| < √(2GM/d)

The closing speed comes from the book's geometry. Tiamat circles at 2.7 AU at 18.1 km/s; Nibiru at its perihelion there, on the 3,600-year orbit, moves at 25.6; at Halley's inclination retrograde (162.3°, as INST-70 read it) the vector difference is 43.2 km/s, head-on 43.7, and at the prograde mirror only 10, pointing the wrong way. The braking impulse that drops her perihelion to 1 AU is 4.80 km/s tangential, 4.91 along the inclined closing line; Δ(1/a) is 0.63 AU⁻¹, a thousand times the nudge the same Nibiru gives a planet from a distance in INST-70.

The impactor is momentum, and the break is a published law. A perfect merger delivers m·u/(M+m): 0.22 Earth masses at 43 km/s, with Nibiru's own pull at 60 Earth radii adding 0.6 km/s; its kinetic energy is 1.6 times Tiamat's gravitational binding energy. Leinhardt & Stewart's catastrophic-disruption threshold, c* 1.9 for planet-scale bodies, puts the largest remnant at 73% of the total with the unequal-mass correction and 35% without; the bench draws both. The impactor that halves her exactly is 0.36 Earth masses and kicks her to a perihelion of 0.64 AU. Marduk himself, 12.7 Earth masses, does not split her: the largest remnant is 70% of the pair, Marduk with Tiamat inside it.

The geometry is exact and does not depend on the channel. After one impulse at 2.7 AU the orbit is 1.00-2.70 AU, e 0.46, period 2.5 years, and the impulse point is its aphelion: the remnant comes back there every circuit. A circular 1 AU orbit needs Hohmann's second burn, 6.2 km/s, at 1 AU. Nibiru's perihelion is at 2.7 AU; it and its satellites are never at 1 AU. The gravity channel, Nibiru passing 7.5 Earth radii from her (2.1 of its own radii, outside its Roche distance for her, tides 5% of her gravity), delivers the same 4.9 km/s and the same ellipse without a hit.

The leash is energy and angular momentum. A satellite at distance d stays when its primary is kicked by Δv at phase φ only if its new relative speed is below √(2GM/d), and it then needs a perihelion above the surface. At 4.9 km/s the bound limit is 31 Earth radii along Kingu's motion, 5.3 side-on, inside the planet against; over all phases, survival peaks near 20 R⊕ at about 25%, is 1% at 10 and zero at 60. The measured rulers beside it are not the bench's: Earth-Moon Δ17O within 5 ppm, the lunar core 1-2%, the Moon 4.51 Gyr.

What survives every dial is worth stating: the impulse that moves her is reachable in one blow from a retrograde Nibiru; the impact that delivers it breaks her to the order of 'two parts'; Nibiru's own gravity could do it without a satellite; Earth and Moon share their oxygen as a Tiamat-born Kingu would. What does not survive is the belt, 2,500 times too light and conceded by the book; the second burn, which no body with its perihelion beyond 1 AU can pay; the Moon's missing core; and the clock, which has the Moon and Earth's oldest rocks older than the event. Whether that is an origin story or a story is a reading the bench leaves to you.

Tiamat's orbit and her upper share, Nibiru's inclination and miss distance, the impactor's mass, Kingu's distance and the kick's direction, and for the 3D view the time and the debris spread. Between them they draw every battle the words could mean, which is the exhibit.

• Her orbit. 1.6 to 4.5 AU, Mars's to Jupiter's; 2.7 by default, the belt's heart. It sets her speed, the closing speed and the impulse: nearer the Sun the blow is smaller and faster.
• Her upper share. 6% to 95%; half by default ('two parts', p. 113), which makes her 2.0 Earth masses; Lynn's 'size of Uranus' preset makes her 14.5 and Earth a fourteenth of her. It sets her mass, radius, binding energy and Roche limit.
• Nibiru's inclination. 0 to 180°; Halley's 162.3° retrograde by default, the prograde mirror 17.7° and head-on 180° as presets. Below about 45° the satellites push her out; past it they start to brake her, but at the default 2.7 AU no impactor reaches 1 AU until about 101°.
• Nibiru's closest approach. 5 to 200 Earth radii, 60 by default: the satellite's orbit and the distance from which Nibiru's own gravity tugs her. At 7.5 it delivers the whole kick alone.
• The impactor. 0.005 to 3 Earth masses; by default the one that, with the flyby, reaches 1 AU. Presets: the one that halves her, a Mars, a Moon, Marduk himself.
• Kingu. Distance 2 to 80 Earth radii (20 by default) and the kick's direction relative to her motion (20°). The Moon view maps every combination.
• Time and spread. The 3D clock runs from forty years before the hit to forty after, resolving hours near it; the debris spread, 0.5 to 6 km/s, sets how wide the ring grows.

Seven claims that make up the Celestial Battle, from the anthology's own sentences to Lynn's report of them, with where each lands against the arithmetic.

1. Start on the battle and press play. Nibiru comes in, the satellite converges, the flash, and the remnant leaves on its ellipse while the lower half shears into a ring where she was. Scrub to +30 years: the ring is complete, at 2.7 AU, not at 1.
2. Press 'the bodies'. Tiamat at 1.2 Earth radii, the incoming satellite two Mars masses, Kingu the Moon's size. Press 'Nibiru passing': the planet that sheds seven of these, sixty radii out.
3. Go to the halves. Read the lower half against the measured belt: 1,010 to 0.4 thousandths of an Earth. Press 'Lynn': Tiamat becomes Uranus, and Earth a sliver of her.
4. Go to the move. The amber ellipse touches the blue circle at the red point and the dashed 1 AU circle at the amber one. Drag the impactor mass: the remnant falls as the kick rises; the two curves are the two forms of the law. Press 'prograde mirror': the kick points outward and nothing reaches 1 AU.
5. Go to the Moon. Drag Kingu's distance and the phase across the map; watch the readout say stays, falls in, or lost. Then read the three rulers: the oxygen that does not separate the stories, the core that does, and the clock.
6. End on the file. The words, the halves, the impulse, the impactor, the break, the gravity channel, the Moon, the rulers, the scar and the spins, Lynn, what is not in the book, then both verdicts.

The honest line between what is reported, what is measured, what is modelled on them, and what is a reading:

In one line: the book's sequence is REPORTED with page numbers; the masses, the oxygen, the cores and the ages are MEASURED; the orbits, the impulse, the impactor and the leash are EXACT two-body arithmetic on them; the break and the borrowed geometry are MODELLED, every choice on a visible dial, every number re-derived by scripts/tiamat-tune.mjs before the build passes; and whether a sequence that is consistent in its own order of magnitude and fails on the belt, the burn, the core and the clock is an origin story is a READING this bench declines to make.
