The average speed of major league curveball pitch is 0.000000110 times the speed of light. In the 1940's, debate over whether there really was a curve in the curveball pitch was settled with the conclusion that the ball does curve; however, an optical illusion caused by the spin of the ball and the batter's perception of motion exaggerates the extent of the curve.
It's about 8,500,000,000 times as fast as a Hurricane
The speed of a Hurricane is about 0.000000110 times the speed of light.

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 9,000,000,000 times as fast as a Knuckleball (baseball)
The speed of a Knuckleball (baseball) is about 0.0000001000 times the speed of light.
