Easy. Take the Schwarzschild metric, find the Christoffel symbols, find their derivative, write down the geodesic equation, change to some cartesian coordinates to avoid endless suffering, get an immense multiline ODE, integrate. That's pretty much it.

The TV and books I consumed as a kid made it seem plausible that people in the future will regularly talk like that.

Now, living in the future, I'm happy that it turned out to be true.

Oddly, the math invoked by that quote is 100 years old.

Were less applications for it back then though!
