It's about two-thirds as fast as The Speed of Light
In other words, 0.666666666677790 times the speed of light is 0.66666666667779 times the speed of The Speed of Light, and the speed of The Speed of Light is 1.499999999975 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 299,792,458 m/s, per the formal definition of the meter. While visible light travels close to this speed in air, it slows to 0.666666666677790 times the speed of light when passing through the glass of a typical window.
It's about 2,000 times as fast as a bolt of Lightning
In other words, 0.666666666677790 times the speed of light is 2,000 times the speed of a bolt of Lightning, and the speed of a bolt of Lightning is 0.001 times that amount.
(atmospheric electrical discharge)A bolt of lightning can travel at up to 0.00032 times the speed of light when arcing from the atmosphere to the Earth. An estimated 280 million lightning strikes strikes occur each year.
It's about 5,000 times as fast as a Meteor
In other words, 0.666666666677790 times the speed of light is 4,800 times the speed of a Meteor, and the speed of a Meteor is 0.0002 times that amount.
(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 0.0000370 times the speed of light and 0.00024 times the speed of light, depending on their size. The fireball effect, known as ablation, ceases once the atmosphere has slowed the meteoroid to a velocity of about 0.00000930 times the speed of light.
It's about 25,000 times as fast as The Space Shuttle
In other words, 0.666666666677790 times the speed of light is 25,810 times the speed of The Space Shuttle, and the speed of The Space Shuttle is 0.000038745 times that amount.
(Orbiter vehicle velocity)The space shuttle orbits at a speed of 0.000025830 times the speed of light. 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 200,000 times as fast as a Bullet (Rifle)
In other words, 0.666666666677790 times the speed of light is 218,000 times the speed of a Bullet (Rifle), and the speed of a Bullet (Rifle) is 0.00000459 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 0.000003050 times the speed of light. 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 300,000 times as fast as a Jet Fighter
In other words, 0.666666666677790 times the speed of light is 300,000 times the speed of a Jet Fighter, and the speed of a Jet Fighter is 0.0000033 times that amount.
(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 0.00000220 times the speed of light. The F-16 has a flight ceiling of approximately 15 km (9.32 mi).
It's about 500,000 times as fast as a Bullet (Handgun)
In other words, 0.666666666677790 times the speed of light is 520,000 times the speed of a Bullet (Handgun), and the speed of a Bullet (Handgun) is 0.00000192 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 0.000001280 times the speed of light. This type of ammunition has been the standard issue round of the United States Federal Bureau of Investigation (FBI) since 1990. |
