Speed of light
The speed of light is a universal constant which is supposedly impossible to breach. However it is now known that the speed of light is approximately 41.7 miles an hour (sometimes inaccurately rounded up to 42 m/h). It is much faster than the speed at which people say "Yee Gawds That's Fast!" but not as fast as the speed when they say "YOINK!" Trying to exceed this speed on any motorway launches the violator backward in time to the previous traffic jam, and become stuck in a paradoxical space/time event known as a Ransome crossroads, from which the Theory of General Relativity makes it impossible to escape.
The speed of light is not to be confused with the speed of darkness. Since darkness is the absence of light, it has only an absence of speed, except on certain nights when you want to get a good night's sleep and darkness speeds away.
The term "Light Speed" is named after the (Bud Light) beer capsules attached to the back of Roddenberry's first Enterprise.
The term comes from the original speed of the Starship Enterprise when launched from the window of a truck travelling at top speed down a freeway. In 1954, when Star Trek was first defined the speed the dog achieved was high-averaged at 41.7mph before impact. As trucks can now regularly reach speeds of upto eighty eight miles per hour without fail, yet light speed remains a very consistent 41.7mph (rounded, inaccurately), this is a sure sign of the advancement of technology as well as the inability of dogs to accelerate or even maintain their velocity when ejected onto the freeway.
How fast is the Speed of Light ?
The speed of light is very very fast indeed, so long as you don't have really crappy wiring done that often screws up your lighting and permits the speed of light to reach three seconds. Apart from that it is in fact so fast that no one has managed to successfully record it, though numerous attempts have been made. Einstein's grandfather, for instance, made an attempt before he was inexplicably killed.
Light travels even faster than sound. That’s why some people appear bright until you hear them speak, for example, George Bush
The simplest and most successful attempt to measure the speed of light was performed by Max Planck, who invented the atomic bomb, uncertainty, fondue and scientology. In this experiment, which took time around Octoberesh of 1885, Max used the Beatrice Davenport particle accelerator in Germany, a twelve inch, wooden school ruler, a sixty watt light bulb and a high speed digital camera.
First he accelerated the ruler to as close to the speed of light as it would go. Then, a clever system of levers and gears ensured that when the ruler was projected out of the end of the accelerator, the light bulb was turned on and the high speed camera activated. It was then simple to calculate:
- The speed of the ruler
- How fast the light overtook the ruler
- The distance along the ruler the light achieved before the ruler splintered against the opposing wall.
From these measurements it was child's play to guess just how fast light travels.
However, during the preliminary calibration runs one of Max's assistants was killed in an unfortunate recreation of the William Tell episode. The ruler failed to hit the apple at all and as a consequence of his death and in deference to the his grieving parents, the experiment was never completed. Despite this setback, Max used the calibration data to calculate his best guess at the speed of light and this has been accepted by the scientific community as a law.
The speed of light is approximately 42 miles per hour. It was proven by O'Sullivan that Einstein was a jew, and also downright wrong with his equation E = mc^2. Although Einstein took the liberty of squaring light in his infamous equation, it was later discovered that the speed of light could only be squared by Heavy.
The speed of heavy is 8.2 miles per hour. Although most people consider light to be the fastest thing there is, heavy is indeed faster but it takes longer to get up to speed and has problems turning corners. Therefore, the speed of heavy is given as an average of 8.2 miles per hour, even though the speed of light is a constant 42. When heavy is fast enough, however, it can square the speed of light, turning some of its mass into energy, losing weight, and eventually also becoming light.
It was also determined that Bonnie Tyler is faster than the speed of night.
Speed of light in a vacuum
There is well documented evidence that the speed of light does not stay constant in certain conditions. Light is often accidentally sucked into vacuum cleaners, and the forces subjected to it combined with the various purifying filters often cause the light to change speed, direction, or shape at random - it's even possible for light to end up travelling backwards in these cases. The exact cause of this is currently unknown, but it is suspected that vacuum cleaners are actually mini black holes themselves, and thus have slight time-space continuum distortion effects on the matter they suck up.
The most famous light-vacuum cleaner interaction, often demonstrated as the prime example of this phenomenon, utilises the Dyson vacuum cleaner. Due to the Dyson's hyper-advanced technology, the effect is magnified several times. The Dyson is turned on at full power, and a beam of light from a powerful torch is directed into the sucking attachment. At first nothing may seem to be happening, but gradually, the dust receptacle will start to emit a purplish glow. The glow will get stronger and start humming. After it has "charged" for a while, the vacuum is switched to the reverse setting, and the glow is aimed at a randomly selected object. Though the stream of light only lasts a split second, and nothing will seem to have changed, the object that was hit by the beam will now have the consistency and taste of cheese. Scientists are baffled as to how this works, but it often makes for a great party trick at scientific gatherings.
Speed of light in a medium
The speed of light in a medium has never been measured because mediums claim this would cause quantum disentanglement and kill their psychic powers, much like Schrodinger's cat. There are, however, secret societies which aim to do just this. They have been foresighted by the Mediums already.
To detect this simply set your microwave to medium and run after the microwaves as they come out.
Speed of light in transparent substances
The speed of light in a transparent substance, such as air or water, is slower than its speed in empty space because photons (the particles that make up light) are invariably polite. Every time a photon bumps into an atom, it stops to apologize before moving on. The more dense the transparent substance in which light is traveling, the more atoms the photons bump into, the more apologies they make, and the lower their average speed.
A group of German physicists recently claimed to have made photons travel instantaneously over a short distance. This was accomplished by giving each photon a gift certificate to a liquor store. Every time these photons bumped into atoms, they felt compelled to buy and share a drink with the offended atom. (As these were microwave photons, they naturally chose to make hot toddies.) By the time the photons reached their destination, they were so drunk that they had forgotten the entire trip, and so they reported that it was instantaneous. This technique would not work over longer distances, because the photons would die of alcohol poisoning.
