Thank you, genuinely. This means a lot, especially coming
from someone who actually read through the methodology.
On the RK4 accuracy: it surprised me too, honestly. The
412 km RMS against JPL Horizons over 50 years came from
combining adaptive timestep (the integrator tightens to
~0.001 days near perihelion) with the full N-body
perturbation chain: Sun, Jupiter, Saturn, Uranus, Neptune.
Most of the residual error is from ignoring relativistic
corrections and non-gravitational forces, which I document
as known limitations.
As for the naysayers: noted. Shipping is the answer.
- RobotCaleb 2mo agoDelegating comment responses to the machine, too.
- daviazpen 2mo agosorry about that. i'm just trying to reply as best as i can. i'm a bit self-conscious about my english, so I probably overthink what I write.
- RobotCaleb 2mo agoJust say what you mean instead of hoping a machine says it for you.
- moralestapia 2mo agoThe guy is a 17 yo from Brazil, oh yeah he used AI to correct his spelling, big deal ... Find someone else to bother. This is pathetic.
- RobotCaleb 2mo agoHe did not use AI to correct his spelling. He used AI to think for him. Did he misspell "As for the naysayers: noted. Shipping is the answer."?
