 It's about 650,000,000 times as fast as a Cheetah In other words, 68 times the speed of light is 664,300,000 times the speed of a Cheetah, and the speed of a Cheetah is 0.000000001505 times that amount. (Acinonyx jubatus)The cheetah can reach speeds of up to 0.00000010240 times the speed of light in short bursts. From a crouching position, the cheetah can attain these speeds in just 2.25 seconds. It's about 700,000,000 times as fast as a Knuckleball (baseball) In other words, 68 times the speed of light is 680,000,000 times the speed of a Knuckleball (baseball), and the speed of a Knuckleball (baseball) is 0.0000000015 times that amount. (a.k.a. knuckler, a.k.a. floater, a.k.a. dancer, a.k.a. butterfly ball) (major league average)The average speed of major league knuckleball pitch is 0.0000001000 times the speed of light. Eddie Cicotte, who was later implicated in the 1919 Black Sox scandal, is credited with developing the pitch ca. 1906. It's about 1,000,000,000 times as fast as a Gazelle In other words, 68 times the speed of light is 1,000,000,000 times the speed of a Gazelle, and the speed of a Gazelle is 0.00000000100 times that amount. (for Thomson's Gazelle, a.k.a. Eudorcas thomsoni, a.k.a. "Tommie", a.k.a. "Tommy")A Thomson's gazelle can reach speeds of up to 0.0000000700 times the speed of light. The gazelle's speed doesn't match that of its chief predator, the cheetah, but a gazelle's endurance usually ensures an escape in distances greater than 500 m (0.3 mi). It's about 1,000,000,000 times as fast as a Hare In other words, 68 times the speed of light is 1,000,000,000 times the speed of a Hare, and the speed of a Hare is 0.00000000100 times that amount. (for European Brown Hare, a.k.a. Brown Hare, a.k.a. Lepus europaeus, a.k.a. Brown Hare)The European Hare can run at speeds of up to 0.0000000700 times the speed of light. While speed is a factor in their escapes, hares evade their chief predators — wolves, foxes, and golden eagles — by fleeing in a zigzag pattern. It's about 1,000,000,000 times as fast as a Greyhound In other words, 68 times the speed of light is 1,010,000,000 times the speed of a Greyhound, and the speed of a Greyhound is 0.00000000099 times that amount. (a.k.a. English greyhound) (approximate maximum speed)Greyhounds reach average race speeds of 0.00000006710 times the speed of light. Despite their racing prowess, greyhounds are not considered energetic dogs — the typical greyhound race requires the dogs to run for less than 35 seconds. It's about 1,000,000,000 times as fast as Secretariat In other words, 68 times the speed of light is 1,210,000,000 times the speed of Secretariat, and the speed of Secretariat is 0.000000000826 times that amount. (at Belmont Stakes, 1973)Setting a record finish, Secretariat ran the Belmont Stakes — a 12 furlong race length — in 2:24, for an average speed of 0.0000000560 times the speed of light in 1973. His margin of victory in the race, also a record-setter, was 31 lengths. It's about 2,000,000,000 times as fast as Michael Johnson In other words, 68 times the speed of light is 1,970,000,000 times the speed of Michael Johnson, and the speed of Michael Johnson is 0.0000000005076 times that amount.

Michael Duane Johnson) (sprinter; 1967-) (at the Atlanta Olympics, 1996)Setting a record that stood for 12 years, Michael Johnson ran a 200 m in 0:19.32 for an average speed of 0.000000034530 times the speed of light at the 1996 Olympics. Johnson was nicknamed "the Man with the Golden shoes" in recognition of the custom footwear worn during these races — a pair of Nikes with a left size of 10.5 and a right size of 11.
