Is ' DARK' Something...like ' Light' is ?
« on: 13/09/2007 00:19:44 »
Dear Sirs,

Here is some light:



nice isn't it....see it there being all busy moving rather quite fast !!

and here is some Dark:



notice how ....well.....Dark it is !.....just sitting there being all non-light-like !!


But.........is ' Dark ' actually something ?..Light is isn't it ?....I know one can say that dark is the absence of light but then is light the absence of dark ?

If ' Dark ' is something, then what is it ?...does it move at C ?

...Am I making any sense here ?

Dark travels faster than light. No matter how fast light travels, dark always gets there first.

Dark is the absence of vision, which is not the same as the absence of light (i.e. UV or IR light is still arguably light, and is visible to some species of life, but to our eyes they would still be dark).

If this is true when I try to read morse the gaps between the dits and the dahs must travel faster and get out of synch which explains my difficulty in reading it.

Does 'dark' really have to be the absence of something ?
Can it not be that everything encroaches on 'darkness' itself..and that ' darkness' is in itself something ?

But have you not said it there yourself.  If that which is not dark is the encroachment of something into the darkness, then it follows that that which differentiates darkness from non-darkness is this encroachment, or lack of it.  Thus it follows that true darkness can be defined merely as the absence of encroachment into the darkness.

Whether darkness can itself contain something is immaterial to what you have said, since you have not defined light as the absence of the thing which is dark, and so have not distinguished light from dark by that which is dark, but rather by the presence or absence of that which is light.  If both light and dark contain dark matter, then dark matter cannot be used to distinguish between light and dark.  If only light, but not dark, contains light matter, then light, or the absence of it, must define both light and dark.

That is very confusing! and a little hard to read ! A bit like whos on first! Or some old play on words... I am lost!

'Lack of something', while a valid concept,  can get out of hand.
'Dark' would be lack of light but, at the same time, you could have a 'lack of food', 'lack of money',  'lack of fun'.
In fact any'thing' , as well as being what it is is also a 'lack of everything else'. Owch.
This is why we don't talk about dark in the same way as light - which is actually SOMETHING.
Except, of course, when we want to play at photography in a darkroom.

So what about a lack of vacuum...?

Or maybe a lack of Dark...?

In other words, can you have a lack of a concept that is itself a lack....

On this forum we are trying to aim at 'lack of ignorance' perhaps?
Are we in with a chance?
