If you had a warp drive, it would be easy. The mathematics are strange the way ley lines are strange, invisible yet divinable. You’ve pulled your way up sterner mountains, fingertip by fingertip. You’ve already compensated for stellar motion, spacetime curvature, hyperspatial congruences. You’ve scratched out hundreds of equations in cold blue hyacinth ink and piled them away in the knitted stocking under your bed, where only Berenice would think to look. Equations that would tell you exactly where to slice a hole between worlds, if only you had the right knife.
