Pythagorean Roulette
Last time we derived the gravitybased equation that powers interstellar travel in gr4Xity. The “jump distance” to another star is determined by a square root function that captures diminishing returns. Squareroot distance functions arise in many different contexts. In this article, we’ll apply another example that’s critical to crafting variation and risk in the world…

The Force of Gravity
Newton’s law of universal gravitation describes the force of attraction between two bodies at nonrelativistic velocities: proportional to each mass relative to the distance each way. In gr4Xity, ships travel to other star systems by “jumping” into the target star’s “gravity well”. Plotting a course requires sufficient gravitational attraction between the ship and destination star…
