The scale of our model is 575,872,239 to 1. So every 100 metres along the track corresponds to more than 57 million kilometres in space. The speed of light is about 1.16 mph, so it is easy to walk at 3 times the speed of light and to cycle at 10 times the speed of light. Every journey down the cycle track ends before it begins and every time you travel on the track you will become a little younger.
