But if you take light away, you're left with darkness. And if you take darkness away, how would you be left with something that has already been taken away?

Haha you got me stunned there, it might not of been the original question but, it's still a good question.

Put it this way: What is a cup with the absence of water?
What is the absence of emptiness?
Either there is no longer a cup or its full again.

well you see their is no such thing as darkness only light.

That is about as good as you can put it.

Well if you want to really think outside the box, darkness is technically not the absence of light, but instead an abscence of what we can see as light. For example, a room can be lit up with infared lights, but this is not in the humans spectrum and they would not detect this, yet other cameras, other species, ect ... can detect this light. Hence the abscence of darkness is presence of light we can see appearing. Everything is a part of your perception, and the words we use to describe it merley pertain to us as humans. As does the concepts of time, space ect...

Good shit, you're pretty smart. I like the way you think.

You can't take darkness away. You can only add light.

This man tells the truth. What your asking is taking away something that doesn't exist.

How does it not exist if you can clearly see it when the light is gone?

........The funny thing about what you said is the the definition of darkness is not seeing anything lol

Think of it like this. You can only add or take away light. Darkness is forever there.

You have to first truly understand what light is and how we perceive it. The spectrum of visible light is made up of waves with relatively "average" wavelengths. We perceive this through our eyes. Looking at infrared (a much longer wavelength), infrared is heat, and in the same way the ABSENCE OF HEAT is 'perceived' as cold. This is in face not the case. We're just not perceiving any heat. Same with light. Light and heat are waves. Darkness and cold are non-entities

Light is energy. Take away that energy and darkness remains. It's a similar relationship between hot and cold. Things that are hot have more energy than things that are cold. But what is darkness and what is cold?

To transform this argument into one we can poke around, let's consider the microwave versus the refrigerator. Think about how long it takes to heat up a hot pocket in the microwave versus how long it takes for a soda that was in the garage to cool in the fridge. The reason for things taking longer to cool is because a fridge doesn't add cold to the soda; it removes heat from the soda. It's a slower process because it depends on the temperature difference of how cold the soda is initially and how cold it will be when the cooling process is complete. We can add energy to things no problem, but we do not yet have an energy vacuum that can suck it out once we put it in.

It isn't possible to add cold to things because cold is not anything on its own. It can't be defined without using heat. If you don't believe me, try to define cold. Then try to define darkness. You'll probably find it just as difficult to define.

The conclusion is that if you don't consider light and dark to be opposites and instead think about how much light there is, ranging from 0-100%, you won't have any confusion. It's only because of the assumption that light and dark are pure opposites that any confusion arises.

You are absolutely correct about darkness and coldness being the lack of something rather than an abundance of something. However your example is a bit flawed. A refrigerator is slow at cooling a soda because it uses cold air (around 4 degrees celcius) to cool the can via direct conduction. A very slow process because there is a large amount of matter in the soda compared to the air. Fewer air particles hitting the can means it can remove only a small amount of energy at a time. The microwave actually uses waves that pass through the food adding kinetic energy by spinning polar molecules (usually water) and is much more efficient. In reality it takes no longer to add energy to a substance than it does to remove it. Every substance has a constant at which energy is transferred. Styrofoam for example resists temperature change quite well because it has a low constant. Metal does the opposite because it has a large constant.

Thank you for sparing me precious time. I was going andto go into resonance frequencies and now i dont have to :)

I am pretty well-versed in heat transfer and the like, but I was keeping this simple. I guess I didn't completely connect the circle here. Ahem.

I merely meant to say that if there was a fast way to cool things, such as a microwave working in reverse, we would use it. But we do not. Therefore, it wouldn't make sense to tell someone to use the microwave to freeze ice cream. It would confuse them, just as it is confusing to think about removing darkness when people only know how to remove light.

And if we're calling out each other's arguments flaws, I owe you one. Conduction would be only applicable to the contact area between the soda and the shelf it sat on. I'd argue that it's convection between the can and the air flowing over it that removes most of the heat.

I see more flaws in your argument. But imma say fuck it and just smoke a joint an relax because I'm pretty sure we both know the point here has been made :) cheers!

Darkness is merely a definition to explain the absence of light, just as the word cold explains the absence of heat. Heat and light require energy, darkness and cold label the loss of.

stonederer Says:

Taking away the light also takes away the darkness, so the absence of light is also the absence of darkness. its semantics.

it must follow the natural pattern of all things, the absence of light is darkness, the absence of something is nothing, the absence of darkness is light, the absence nothing is something.

Id just like to point out... Nothing is true. Everything is permitted. Albert Einstein was extremely smart as we all know. He often would question things we know in order to test them. Why cant the absence of darkness be a void? Total darkness is very rare. It only exists around a black hole. All light energy is taken in and nothing is left. The absence of darkness could very well exist. It could be anti-energy. We know so little in this universe that it is entirely possible that everything we know about physics is wrong.

bakayurei Says:

but since we've defined light and dark the way we have, we'd have to be talking about other things entirely if we started giving them other properties, like existence or whatever.. dark is just the state of things where there's no light, because we've defined that term like that .. if we were talking about something that didn't have that definition, then it wouldn't be darkness

Tue, 07/17/2012 - 8:52am
baked101 Says:

Maybe a black hole? Since light is energy, and darkness is neutral, what if a black hole is the otherside? And is just the complete opposite of light and darkness is just the middle man. Bam mother fuckers!! Caboom. Sham. Caapow!

MachoHan Says:

Darkness is not a quantity. It is a word describing the absence of light. So if you measure darkness you measure the amount of light in an area and not the amount of dark.

Therefore the absence of darkness is light.

What I really want to know is this... What is the opposite of matter. Is it anti-matter or the absence of matter?

Tue, 07/17/2012 - 3:29pm
bakayurei Says:

if you can say that dark is both the absence and the opposite of light, then a vacuum would be the opposite of matter.. .. opposition isn't a property that's in things in themselves tho, it's to do with where we 'locate' things in our heads.. so call it whatever you want, whatever suits the purposes of whatever discussion you're having.. matter's opposed to antimatter and they're both opposed to empty space

darkness is nonexistent. darkness cannot be "absent" because darkness in itself is absence. the absence of light. you can't be missing absence, otherwise it is just the presence of something i.e. light.

whats evers actualy there, we just wouldnt be able to see it with out any light or dark to contrast it
