A place for majestic STEMLORD peacocking, as well as memes about the realities of working in a lab.

Rules
This is a science community. We use the Dawkins definition of meme.
You can easily cross calculate between various, inertial frames of reference. The problem is that earth isn't sitting still in an inertial frame. We spin around the sun, and we orbit the center of our galaxy. We also get nudged about by the pull of other stars.
Tracking a time jump (or technically a time-space jump) would be easy, if you just wanted to be within the solar system. With measurements the earth-moon gap would not be too hard. Hitting a surface exactly would be another story. Miss by a meter and your cut in half by a wall or floor.
