You almost have to feel bad for Isaac Newton. Despite all of his groundbreaking discoveries in mathematics and physics, his accomplishments have just been eclipsed by a man named James Risner who has somehow bent the laws of the universe to build an infinitely-looped spiral model railroad.
Powered by what appears to be seven HO-scale locomotives, Risner’s creation also works in reverse. But based on our scientific calculations, which are in turn based on the science we learned from the original Superman movie, leaving this setup running in reverse for too long will undoubtedly start to turn back time.
