Light-Speed Earth Tour in 0.13 Seconds: A Mind-Blowing Visualization
A YouTube video by Airplane Mode simulates circling the Earth at light speed (186,000 miles per second), completing the trip in about 0.13 seconds (eight frames) and comparing it to the speed of sound, noting that no aircraft can reach such speeds and that hypersonic travel remains far slower but is the closest real-world visualization.
