Sure, but the goal of these simulations is qualitive results about how galaxies behave, not a quantitative prediction of exactly where every star will be in a billion years.
It's like predicting climate vs. weather.
- uoaei 4y agoAny smoothed and incomplete approximation to climate models is also devestating for qualitative similarities of results to data. The point is that the chaos inherent in the dynamics means that n-body solvers that aggregate e.g. spatial regions into low-rank approximations are losing enough detail that it could result in different dynamics being expressed. Like using too large of a mesh size in CFD calculations.
