If I derive Kepler's laws from positions of planets, I have preserved elements of their motion for replay as well.

- Retric 6y agoThe laws alone don’t have enough information to replay their motion without each planets location, a foci, the orbital period, and an associated timestamp or equivalent information. So, include that data and it’s lossy compression, exclude it and it’s not.
