What udder nonsense.
My physics teacher takes the spherical roast beef as an example for heat convection.
Anna Cramling, women’s international chess master, should review this paper, having popularized the Cow Opening.

This is some bull
One of the cool facts about gravity is that the gravitational field of a body 'feels' spherical at a distance, even if those bodies are not spherical themselves. There are higher multipoles but they are increasingly suppressed the further you are from the body. So at least for gravity the spherical approximation turns out to be good and justified.
for simulating gravity in particular you can do one better, since a sphere is in turn gravitationally indistinguishable from a point mass due to the https://en.wikipedia.org/wiki/Shell_theorem#Force_on_a_point...
and you can do one better than that - Birkhoff's theorem, the relativistic analogue of the shell theorem.

This deserves a simulator
