light
« on: 11/03/2015 11:20:44 »
White light is presently said to be a mixture of spectral frequencies of 400nm-800nm.  Dark is said to be the absence of light.

I propose that dark has subsets, humans perceive dark as the absence of frequency of 400nm-800nm, a state rather than an absolute.


Other species evidentially observe it is light compared to us, devices show light is still there to low intensities such as infra red and even CBMR.

I propose that dark is a void the absence of all Em radiation.

I also propose that a void is interwoven with Em radiation, a dark space that is transparent to light and allows light to pass through, a passive dark space.

It is also said that white light has no specific frequency , I propose that the transparent state has a zero value to sight, an equilibrium to sight and only by interference in and of the transparent equilibrium do we see objects or mediums as a spectral magnitude and ''colour''.

The whole universe is full of light, but we cannot see it until it bounces off something which sends it in our direction.

Yes the whole of empty space is see through, we only observe light interaction with matter or a medium that is reflected. Observation is dependent of this action.

If there was no matter or medium in space, we would not see anything it would be a darkness to us, would you agree with that?

Added-

A suggested  communications protocol to the brain by a low voltage differential signalling of EM radiation interaction with matter or a medium that sends a transparent echo of EM radiation interference back through the visual transparent constant of  itself which is formed by matters resistance force to the opposing force of light thus giving propagation and pressure magnitude to spectral content each of which content is capable of transmitting messages modulated onto light waves in their perceived spectral content that travel through the constant equilibrium of light to sight, a carrier signal to the brain unseen by the constant transparent wash of Incident rays.
The information exchanged through the constant transparent transmission medium the main means of mass communication. The nature of a communication the actual data exchanged and any state-dependent behaviours is defined by its specification and the brains ability to interpret this information.
A communication transmission medium  that refers to a physical transmission medium such as the constant of EM radiation in passive space,  a Synchronization of the coordination of timing events to operate a system in unison to sight. The familiar conductor of an orchestra that serves to keep the orchestra in ''time''.

Your proposal would be rejected by any physicist. Darkness is merely the absence of visible light. That's all there is to it.

Darkness is the natural state behind the light, interwoven with the light. Dark from a Human perceptive is the absence of frequency, 400nm - 800nm, visible light to us.  Other species see different, devices detect light different, darkness is the absence of light is very narrow and complacent.

Darkness to us is a state, when we perceive it to be dark, other species perceive it to be light.

Absolute dark space (a void) is also transparent to EM radiation, Em radiation is a neural stimulus, there is not any evidence to suggest that light exists outside of the brain?


Our eyes are the remote sensors to change of the transparent constant to sight  of EM radiation, having a clarity in space, such has the low refractive index of air giving the Em radiation no spectral interest.

An equilibrium invisible constant made by the timing mechanism of neural pathways of the brain, being synchronized to fire in tune to the constant like an electron gun on a tv set.

An equilibria to the em radiation of the brain that detects offsets of the equilibrium in a space such has matter and light interaction, by a timing offset of the interaction of EMR with matter and photo electrical effect causing a colour temperature that is thermally detected and processed by the brain. 

A filter can be placed in a river to slow down a rivers flow, a denser filter will slow down the rivers flow even more, the river wants to travel at velocity x, but the filters make the river flow at x,y,z,

Another way of explaining it is to imagine bouncing a tennis ball off a wall, the wall is dense so the wall does not give in any distance, making the absolute of speed and reflective time, a fast interaction of force.  Then imagine we make a wall out of sponge, the ball  hits the wall and the much softer sponge cushions the force and gives distance by pressing in, a distance that gives a slower reflective rate and reflective force.


This is how matter works in simple terms with absorbing and reflecting properties with EMR interaction and a timing mechanism of the interaction creating  different propagation wavelengths.

Another way of looking at it is that all matter is like a water logged sponge and  always at its maximum of absorption of radiation, and has it continues to gain radiation it starts to leak an isotropic puddle.   The more it gains, the more it leaks because of the capacitance of the matter.

What about the existence of photosynthetic life ? , or solar-power ...

That would be EM radiation.   I am not saying that there is not a something, I am saying that there is no evidence to show that the something is a ''light'' outside of the brain and not just a wave of energy perceived as light.

Your provided image shows a change in the transparent state of em radiation.  A plant also does not know is light, for a plant is always in the dark without sight.

Conventionally, light is that part of the electromagnetic spectrum that can induce transient chemical effects such as vision. The extent of the visible spectrum depends on species and individual characteristics.

You can of course see "direct" light from stellar objects and "indirect" (i.e. relfected) light from moons and planets.

Plants respond to light by various means which are entirely analogous to animal responses, i.e. chemical change inducing movement, color change, and the synthesis of longterm metabolites. Various animal species respond to light despite having no evidence of a brain or image-forming equipment.

It's not a good idea to adopt idiosyncratic definitions of scientific terminology. At best, nobody else will understand you, and at worst, you will confuse yourself.

There is no evidence to suggest that we do not see in the dark when EM radiation is present, a sort of night vision.

Night (scotoptic) vision has nothing to do with seeing in the dark. No photons = no vision. You can also get retinal stimulus from Cerenkov radiation and ultraviolet fluorescence in the aqueous humor, but neither counts as "vision" as they convey no image information.

We shouldn't define things rigidly by human constraints. We talk about light and visible light, and this allows the former term to include frequencies which our eyes cannot (normally) detect. Other species can see into the ultraviolet and infrared, so they can see in artificial conditions which are totally dark to us. We could distinguish between dark and absolute dark for conditions in which no creatures or cameras can see, but then there would still be arguments about where the limits are in frequency terms. Incidentally, some people who've had their eye lens replaced with an artificial one have found that they can see infrared light - a faulty batch had the IR filter layer missing.
