What is light, without darkness?

Yeah. :

 

...I was aware but didn't think about the people sleeping in mixed day/night times...and after my graveyard shifts I sleep better during the day-provided I can get some darkness in my room (not hard-I just seal all incoming light )

And the sun thing...I don't really get what you said...but what I meant by my post is...if the sun exploaded...you know it goes boom?

Are are you refering to the "too much sun" thing (I only used sleep deprivation if we say had nothing but pure blinding sun light entering every corner of the world-though some could die from the heat it'll be in...)

 

I think first you have to ask what darkness is. Tehuber1337 answered this rather well, but it seems to have been ignored, so I'll have a stab at it:
darkness is defined by varying degrees of light, without light darkness would not exist. For instance; there was no word for vacuum until the absence of air was discovered. Shadows almost always have light in them.
You might as well ask if heat can exist without cold.

 

Oh...so if there was no darkness and absolutly no shade we might not all be burnt to death/over heat/possibly get no sleep?

(I can't sleep when it's over 25 degrees )

 

0.0 I love heat =)

 

Well said.
CLAP CLAP CLAP.
Without death, there is no life.

 

What the fail... Why bother thinking about something like that?

 

This thread makes me lose faith in humanity. Even moreso because I know that however I construct this, it's going to be ignored for convenience by the people who actually need correcting. I wonder sometimes if this is how the world continues to manufacture stupidity.

What is light without darkness? A stupid fucking question considering darkness is an abstract concept we use to describe the lack of intensity of a certain wavelength of electromagnetic wave in any given area. Darkness isn't a thing, it can't be measured, and thus it doesn't exist and cannot have light in it. We don't have anti-lumens to measure how much dark there is. We have lumens to measure light intensity, though. Light is real. It is measurable. Darkness is fake and can't do shit.

 

Bite me.

 

Unfortunately, I WILL get into the physics.

Shadows are the consequence of photons of visible light being absorbed/redirected by an object. The shadow is a consequence of the object rather than the light itself, and this only "visibly" happens when the wavelegnth of the photons is between approximately 440nm - 720nm , aka "visible light" (note: Electromagnetic Shadows are possible with any wavelegnth of light, however almost none are visibly observable).

Darkness is actually defined as the absence of light, therefore darkness is directly dependent on light.

Philosophical argument voided by the power of physics.

 

Stop being sciency >.>

 

Sorry pal, you've been inb4'd three times already.

I'm not sure we can achieve greater succinctness by continuing to refine this same explanation =/

By the way, the phrase "light photons" is redundant, I believe. As I said earlier, light is electromagnetic radiation and electromagnetic radiation only travels as photons.

 

"light photons" was supposed to refer to visible light.
*edits original post for clarity*

 

darkness exist because light cant reach it so light can exist without darkness and its light that overpower the darkness

 

I already said light overpowers darkness.

 

it's light.

 

If you didn't want to get "sciency" you should have asked a more philosophical question like 'What is good without evil?' or 'What is pleasure without misery?'
