The speed of light in a vacuum is exactly 299,792,458 metres per second (or 1,079,252,848.8 kilometres per hour, which is approximately 186,282.397 miles per second, or 670,616,629.4 miles per hour).

Think about it, when you switch the light on, you get light speed. When you see lightning you see a flash. When you watch a movie you view pictures. All from light, which is fast light.

But then, when you switch the light off, you get dark speed? When the lightning dissappears, you get darkness. When you switch the television off, you see no pictures.
So then, at what speed is Dark Speed?
I might even be way off, WHAT is the speed of dark?

Is it just simply -299,792,458m/s? How would you measure the speed of dark when the Universe is dark?

Any ideas? :)
 
But hang on, how do you know dark is the absense of light and not the other way round.
As an analogy, is a Zebra white with black stripes or black with white stripes?

Taking the above into consideration then how was light measured, and surely the same can be done to dark. One does not know the boundries of the Universe to make the statement dark is the absense of light! :p

I actually got my mate to help me. First we worked out the speed of sound by him shouting at me and waving at the same time. Then I timed how long it was between me seeing the wave and hearing the shout, in order to deduce the speed of sound. I made it approximately 330 m/s.

Then I got him to say "go" exactly 1/66 seconds before he hit the 'on' button on the torch, so that me hearing him say the word would coincide with him turning the torch on.Then I timed the interval between the word and me seeing the light, and used that to calculate the speed of light. From there I was able to use the results of my previous experiment to calculate the speed of dark.

And yes, we just have really fast fingers and a really sensitive stopwatch.

So instead of going to the pub/going out with your gf you and your buddies conduct scientific experiments? :D :p (kidding)

Aha, but your method for finding the speed of sound is no adequately accurate for the purposes of this experiment, you would have to take into account the speed of light in the first place!

Seems this new fangled Science malarkey you're going on about isn't all it's cracked out to be!

You see i'm with this guy. I wanted to say that but didn't know how! :p

Anyone else with theories of darkness? :D

i see, well this is the only formula for momentum ive learnt so far in my physics course. I guess even though we study particle physics also, we dont study to the extent of involving other concepts such as laws of momentum etc.
Interesting though.

A Level right ;)
