I then ask you to observe a colour chart with a spectral range between about 400 nm and 800 nm that gives rises to visual perception by object interactions with the constant, a value different than the zero clear value of the constant.
 
A good reply thank you, but if you place your hand under your seat, you will find a pair of thermal googles, if you look through the goggles you can clearly see ''Photons'' and my presence on the stage.
You will also notice a red laser dot on your chest, you can not see the infra red beam but you can see the dot.

So are we agreed that darkness is the lacking of intensity and frequency of Em radiation that is equal to observable sight, that in affect impairs sight, but not an absoluteness of the absence of light, and if we could see by low intensities such as infra red,thermal detection or a cosmic microwave background it would never be dark and always perceived light?

Darkness is the absence of certain light that is needed for sight but not an absence of all light?

Except there is a flaw with this: Those Thermal Goggles (assuming you mean Infrared Goggles) can detect the lower-frequency Infrared spectrum that our eyes cannot, and then re-transmits the image (via a screen) to our eyes in the visible light spectrum. It isn't that the thermal goggles are allowing you to "see" infrared, but rather, it is merely translating the infrared into a spectrum we CAN see.

Think of it like having someone talk to you in a language you dont' understand (say, Latin) - you could, in theory, say that you are incapable of conversing with this person. Now, add in a translator that the two of you speak through, and you are able to converse.
 
Dark is the lack of neural activity in the brains sight mechanism,
Light is an increased neural activity in the brains sight mechanism.
So it IS dark to a blind man, or when I close my eyes.
This somewhat negates your claim that dark is a state - according to your definitions here "light" and "dark" are purely individual perceptions/ phenomena.

A device can see unseen light that the eyes can not detect
This is wrong since you just defined light as "increased neural activity in the brains sight mechanism", i.e. light is nothing whatsoever to do with "external conditions" (as it were) OR "devices" you've reduced it to something that happens internally.

dark is a perceived view by visual impairment.
Again, no. See previous comment.

I do not see a flaw, I see that regardless of the conversion by the goggles , the goggles show us that there is still light/Em radiation in the dark and the darkness is a flaw/impairment in sight rather than a state of the absence of light.
I see the dark as a low level of Em radiation undetectable by sight that is a sort of igniter/conduit for Em radiation, a sort of low voltage turned up .

Again, no. See previous comment.
See Kitamara post. The devices transmit light into your eyes to increase your neural mechanism of sight.
You can only observe the object on the device through the device.

Okay - then here's a question for you:
1) How do you normalize this idea with the fact that humans can, under the right conditions, see infrared:
http://io9.com/under-the-right-conditions-humans-can-see-infrared-1665448040

Inside the human eyes are photopigments - pigments that change structure when they get hit by a photon. The part of the photopigment that changes its structure is the chromophore. It is shackled to what's called an opsin. Give a chromophore just the right amount of energy, and it changes its structure, cutting the opsin loose and starting the process that ends with what we call "seeing." The only photons with the right amount of energy to change a human chromophore are in the 390-720 nanometer wavelength range. Infrared, in the 1000 nanometer wavelength range, is too big and too low-energy to knock a chromophore into changing its shape.

But if huge amounts of infrared photons flooded the eye over a short period of time, two infrared photons could hit the chromophore at once. Their combined energy is enough to cause it to change its structure and allow people to see what they otherwise wouldn't. Two 1000 nanometer photons add up, energetically speaking, to one photon of around 500 nanometers - which is in the green range of the visual spectrum. So infrared light, if concentrated enough, would leave us seeing green.

2) What do you do to normalize this outside of the human species? For example:
Several animals, including beetles, bed bugs, vampire bats, and pit vipers can detect the infrared spectrum:
Other animals, notably birds, can detect the ultraviolet spectrum.

It seems like your argument is based more around the human perception of "light" which is visible light by connotation. There is, of course, the potential for em radiation in the dark - however, there are situations where thermal (infrared) goggles will not help, especially if they have less than top-end sensors - for example, infrared security cameras typically add a set of infrared LED's around the camera to "shine" light upon their viewing area.

One could argue, though, that there is always some kind of radiation, be it from radioactive decay to cosmic background noise.
 
See Kitamara post.
Oh, the one where he (correctly) pointed out a flaw in your argument?

The devices transmit light into your eyes to increase your neural mechanism of sight.
Make your mind up.
Define "light".
First you said:
Light is Em radiation ,all that can be observed by the eyes or device.
and then you changed it to:
Light is an increased neural activity in the brains sight mechanism.

One or the other (at least) is wrong.

You can only observe the object on the device through the device.
What?

What?
One leads to the other, Light is a specific frequency of Em radiation that gives an increased neural activity in the brains sight mechanism to be perceived as being light.
 
Exactly - "light' is a very specific portion of the EM Band. It isn't a case of "one leads to the other" - it has to be a very specific bit of EM Radiation
 
One leads to the other, Light is a specific frequency of Em radiation that gives an increased neural activity in the brains sight mechanism to be perceived as being light.
Wrong again.
Your first one says "all that can be observed by the eyes or device".

Your basic problem here (apart from your unremitting stupidity) is that "light" and "dark" (regardless of which set of definitions you choose) are mutually exclusive.
If you can see it is, by definition, light.
If you can't see it is, also by definition, dark.

This shows, conclusively, that we do not see in the dark.
 
I now ask the attendant to turn the light on and ask you to observe the dark is now see through , clear, the light in the air is not visible , a speed can not be seen, a spectral colour or colours we can not see , the total values are zero, it is clear.
But air is not totally clear. The new high intensity green and blue lasers have visible beams even in dust-free air because of Rayleigh scattering off O₂ and N₂ molecules.

Picture 2 of http://en.wikipedia.org/wiki/Rayleigh_scattering : "The beam of a 5 mW green laser pointer is visible at night partly because of Rayleigh scattering on various particles and molecules present in air."

Well this thread has already gone of the topic, people bringing man made lasers and all sorts to the lecture.

One person answered the actual opening questions.

Ok, you are now all in the dark, can any of you see me on the stage any more?

Can any of you see through the dark, is the dark of now, not obscuring your vision?

I did not ask for the whys, a simple yes we agree at the opening stage of the talk would of done.

Again I have been thrown off track in showing some simple axioms.
 
I was rushed into turning the lights on , I am sure some of you became confused in the dark.

So far you would have to agree that when the lights were turned off , you could not see me on the stage without using any other means other than your eyes.
So you are agreeing that you can not see me on the stage in the dark and can not see through the dark, is the second no a disagreement to the dark being obscure to sight?

If so understood.

Are we agreed that in the dark there is less neural activity in the brains sight mechanism, we observe a darkness in our own brains?
 
Oh stuff it, here is the result - When we can not see but our eyes are open it is not really dark, you can see through the dark because it is transparent because it is actually light and keeps your brain coupled to matter by the dark light that you can not see, that is why you can see the laser dot but not the beam.

Then when the light in the dark increases in energy, the Neural activity in your brain increases that allows you to see at a higher intensity.

The white light then in space is not white but clear, because the brain interprets it has clear an equilibrium to the brain to make the dark light see through.
 
You still have more to say don't you?

Otherwise, you could just be wasting peoples time with this thread.

Gibberish.

Um, yes it is.
YOU have already stated that light "is a specific frequency of Em radiation that gives an increased neural activity in the brains sight mechanism to be perceived as being light".
If that SPECIFIC FREQUENCY is not there then it is dark.
If it IS there then it's NOT dark.

you can see through the dark because it is transparent
No.
Dark is not a thing.
Dark is not transparent.
We cannot see when it's dark.

because it is actually light
Oh wait, when it's dark it's actually light?

and keeps your brain coupled to matter
You have previously been told that our brains do NOT get "coupled to matter".

by the dark light that you can not see
Dark light?

that is why you can see the laser dot but not the beam.
Pure crap.
(You have ALSO been told why we don't see a beam, and that under certain conditions we CAN see the beam).

Then when the light in the dark increases in energy
If there's light then it's not dark.

the Neural activity in your brain increases that allows you to see at a higher intensity.
Drivel.
What do you mean by "see at a higher intensity"?

The white light then in space is not white but clear, because the brain interprets it has clear an equilibrium to the brain to make the dark light see through
