 It's about 0.000000005 times as fast as The Speed of Light In other words, 0.00081 miles per second is 0.00000000434823693930290 times the speed of The Speed of Light, and the speed of The Speed of Light is 229,978,267.964470 times that amount. (C) (in a vacuum)The speed of light (and all other electromagnetic radiation) in a perfect vacuum is known as "c" and measures 186,282.397051220 miles per second, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 124,188.264702890 miles per second when passing through the glass of a typical window. It's about one-seventy-five-thousandth as fast as a bolt of Lightning In other words, the speed of a bolt of Lightning is 77,000 times 0.00081 miles per second. (atmospheric electrical discharge)A bolt of lightning can travel at up to 60 miles per second when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year. It's about one-thirty-thousandth as fast as a Meteor In other words, the speed of a Meteor is 32,000 times 0.00081 miles per second. (formally Meteoroid or meteorite, depending on the context; a.k.a. "shooting star", a.k.a. "falling star")Small meteoroids enter the Earth's atmosphere at speeds between 6.90 miles per second and 45 miles per second, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 1.70 miles per second. It's about one-six-thousandth as fast as The Space Shuttle In other words, 0.00081 miles per second is 0.00016834 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 5,940.40 times that amount. (Orbiter vehicle velocity)The space shuttle orbits at a speed of 4.81170 miles per second. During liftoff, the space shuttle accelerates to orbital speed in 8.5 minutes, consuming over 1.59 million kg (3.51 million lbs) of propellant in the process. It's about one-seven-hundredth as fast as a Bullet (Rifle) In other words, 0.00081 miles per second is 0.00142 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 704 times that amount. (5.56 x 45 mm, a.k.a. 5.56 NATO)A 5.56 x 45 mm cartridge is fired at a velocity of 0.5690 miles per second. As the NATO rifle cartridge, it is used by the military forces of more than thirty-one countries, including use in the M16 series, M4 Carbine, HK-416, and M249 Squad automatic weapons used by the United States armed forces. It's about one-five-hundred-fiftieth as fast as a Jet Fighter In other words, the speed of a Jet Fighter is 530 times 0.00081 miles per second. (for Lockheed Martin F-16, a.k.a. Fighting Falcon, a.k.a. Viper) (maximum speed at altitude)An F-16's maximum speed at altitude is approximately 0.420 miles per second. The F-16 has a flight ceiling of approximately 15 km (9.32 mi). It's about one-three-hundredth as fast as a Bullet (Handgun) In other words, 0.00081 miles per second is 0.00339 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 295 times that amount. (for .40 Smith & Wesson 135 grain Sierra JHP, VV 3N37 powder, Fed. 100 primer, Remington case) (muzzle velocity)A 0.40 caliber Smith & Wesson bullet has a muzzle a velocity of 0.2380 miles per second. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990.
