Speed of light around Earth, 7.5 laps per second

If you could make light bend around Earth, it would orbit 7.5 times per second (near the surface). That's 0.13 seconds per orbit! Play around with the SPEED in settings, as I uploaded this at 60 frames per second. *Animation by Dr. James O'Donoghue using NASA imagery. *Share/use as you wish, credit is appreciated.
