Explaining Everything on Instagram: "This simulation offers a hyper-realistic glimpse into what a supersonic rail journey in Japan could feel like—traveling at 1,337 km/h (nearly Mach 1). 🚄💨 While today’s fastest maglev trains top out around 600 km/h, future concepts suggest that combining magnetic levitation with low-pressure or vacuum tube systems could unlock entirely new speed limits. By virtually eliminating air resistance and friction, the train could glide at extreme velocities while st
