What If You Kept Getting Faster and Never Stopped?

Your speed doubles every hour. It never stops. Where are you after 28 hours? You start on a desert road at walking pace: 5 km/h. One hour later you're jogging. Then you outrun Usain Bolt, overtake highway traffic and pass a sprinting cheetah. Keep doubling, and you overtake a bullet train, a diving peregrine falcon, a passenger jet, Concorde, the SR-71 Blackbird and the X-15, break the sound barrier, and feel the air itself start to glow around you. At orbital speed you leave the ground, then you leave Earth, cross the Moon's orbit and beat the fastest thing humans have ever built. Then physics pushes back. Past half the speed of light, doubling stops working. You can only add more 9s: 90%, 99%, 99.9%, 99.99%. And time itself starts to stretch. Every speed and record in this video is real. Only the suit is imaginary.

Fastest spacecraft (Parker Solar Probe, 692,000 km/h), Guinness World Records: https://www.guinnessworldrecords.com/... Wild cheetah top speeds (Nature, 2013): https://capitalfm.africa/speed-and-br... Note: the time-dilation figures (e.g. 1 s for you = 71 s on Earth at 99.99%) come from special relativity. Above 50% of light speed the video stops doubling, because nothing with mass can reach the speed of light.
