If you think I did something awesome, consider buying me a coffee:

comment Does one need to take into account finite gravity speed in N-body simulations?
@Walter true, edited. As I understand it, this is justified for galaxies because the time scales involved in galactic evolution dwarfs the travel time of gravity through the galaxy, so any effect is negligible. Still! My question stands...Perhaps a good follow-up question is then: how to quantify the error between the models; plain Newtonian, corrected Newtonian, and GR?
