How far away is everything right now?
Real distances for this second. Press send and watch one pulse of light crawl out to each world at its real speed, sped up so a whole hour fits in twelve seconds.
What is fast out here?
Every bar is a real speed measured right now. Each one races the same stretch: Earth to the Moon. The clock speeds up as it runs, so watch the elapsed time, not the bars.
