How much brownfield work have you done?

People can hide the fact that they have a big ball of mud fir a very long time, and they only want to talk about improvement after hunts have gotten miserable.

4-11 years depending on exactly what you'd define as "brownfield"

True but beside the point. The same point stands: you can always find a way to make a worthwhile improvement in two weeks - something that's useful on its own, even if it's also the first step of a much bigger improvement plan.

Consider, then, that your experience might be limited in ways that you're unable to see due to that experience-bias.

Unlikely. I used to go looking for tasks that couldn't be broken down; I'd get excited when someone would claim that their task couldn't be broken down. But they always could, and it was never even hard.

My task is to implement a model that takes advantage of unified field theory to simulate arbitrary bodies in spacetime, first the mathematical models behind it need to be created then implemented in software.

Sure, sounds straightforward enough. Start with simple cases (e.g. universe is a unit circle), you can definitely implement useful pieces within two weeks.

That's not a real (i.e. user-facing) requirement.

You should follow your own plan, a Nobel prize in physics awaits.

There's no money in doing useful incremental pieces of physics (and precious little even for the big milestones), unfortunately.
