3The n-body problem The problem of finding, given
the initial positions, masses, and velocities of
n bodies, their subsequent motions as determined
by classical mechanics. Poincaré discovered
Newtons clockwork Solar System did not exist.

9- 2 Approaches
- Use geological record to determine values of
celestial mechanical constants (fundamental
frequencies) and resolve state of Earth - Mars
resonance. - Use geological record to reject possible
numerical solutions of Solar System behavior. - Both absolutely require continental drilling
10Approach 1 Use geological record to determine
values of celestial mechanical constants
(fundamental frequencies) and resolve state of
Earth - Mars resonance. Use the geological
record as an interferometer.

41Getting at the g3-g4 Resonance One could even
dream that if the succession of the transitions
from the 12 to the 11 resonance were found and
dated over an interval of 200 Ma that this could
be the ultimate test for the gravitational model.

50Conclusions
- Existing records insufficient to provide long
enough records to precisely determine g4-g3 or
s4-s3. - Cannot robustly exclude huge numbers of possible
solutions without composite record spanning at
least 200 Ma. - Need pairs of low and high latitude records to
see both precession and obliquity separately. - Need to find the best places for long continuous
records - drilling is essential. - Local forcing good (!) integrated records bad!
51What will it take ?
52One million dollars! ahem! I mean One BILLION
dollars!
53What will it take ?
- Need about 170 m.y. of core.
- Need at least 25 m.y. in each continuous record.
- Need at least 25 overlap in times between
sections. - Thats 9 coring projects x 2 for high and low
latitudes. - At 5 M per project, thats at least 90 M.
54Where do we go?
55Eocene, Green River Formation, Wyoming
56Early Cretaceous Yixian Formation, Liaoning, China
57What would we get?
- Complete description of the orbital dynamics of
the Solar System. - Ability to produce insolation target curves for
any arbitrary time allowing lt 20 ky stratigraphic
precision - Improvements in precision of 104 to 1010) in
celestial mechanical measurements (Laskar, 2008). - Tuning of radiometric decay constants.
- Precise determination of the J2 value of the Sun.
- Constraints on the Velikovsky-ish behavior of the
inner planets. - Solar-System-wide tests of General Relativity.
58We cannot solve the n-body problem for the Solar
System and resultant chaotic behavior
analytically as Poincaré showed. But we can tell
which possible numerical solutions are not
possible and which are possible and completely
describe the gravitational behavior of the main
bodies of the Solar System - By using
continental coring.
