Show HN: Built an space travel calculator with vanilla JavaScript v2

built this fun web to visualise how fast or how far are we since birth using 4 velocity vectors Rotation,orbit, solar system speed and galactic drift relative to cosmic microwave background. I’m currently using ~600 km/s for the galactic velocity, but I know this is a debated figure depending on the reference frame Built with Vanilla JS (no frameworks). added a feature to generate a "Cosmic Receipt" of your journey. added cosmic connection section to compare with ur friend and partner added seassion travel log
