That's why I'm always wearing black until I can find something darker.

The only thing darker than black must be invisible, neither reflecting nor absorbing. The Emperor's new clothes. "matter of fact it's all dark" is a part quote from DARK SIDE OF THE MOON by Pink Floyd. Sure electrons and sub particles etc. can be represented as light points in visual displays, and can be detected by instruments, but that doesn't mean they all give off visible light. Otherwise we would be blinded by everything, even our eyelids would glow. But if you include all radiation, visible or not, yep, radiations everywhere. Our stomachs give off noticeable radiation from breaking down food.

According to nova channel it's called neutrinos and yes they say it's faster than light .

Neutrinos not faster than light ICARUS experiment contradicts controversial claim. http://www.nature.com/news/neutrinos-not-faster-than-light-1.10249

Dark would have to be slower than many things, since it has no particles vibrating oscillating spinning to heat it, (making it observable), and neither does its surrounding dark. So it is cooler. Could dark then conceal nano - pico 'particles' or clumps of absolute zero too small to register individually, but seen/measured from a distance, in space. Like the reverse of big obvious noisy black holes, super small obscure points of absolute zero hidden in plain view everywhere that heat and light is not. Maybe like dark energy.

Dark energy and dark matter are placeholders for something we at present cannot define. At actual absolute zero there is no movement/thus no energy. Even the fundamental forces of the Universe as we understand them break down if there is no 'force carriers' In quantum field theory, force carriers or messenger particles or intermediate particles are particles that give rise to forces between other particles. These particles are bundles of energy of a particular kind of field. There is one kind of field for every type of elementary particle. Quantum field theories describe nature in terms of fields. Each field has a complementary description as the set of particles of a particular type. A force between two particles can be described either as the action of a force field generated by one particle on the other, or in terms of the exchange of virtual force carrier particles between them. The energy of a wave in a field (for example, electromagnetic waves in the electromagnetic field) is quantized, and the quantum excitations of the field can be interpreted as particles. The Standard Model contains the following particles, each of which is an excitation of a particular field: Gluons, excitations of the strong gauge field. Photons, W bosons, and Z bosons, excitations of the electroweak gauge fields. Higgs bosons, excitations of one component of the Higgs field, which gives mass to fundamental particles. In addition, composite particles such as mesons, as well as quasiparticles, can be described as excitations of an effective field. Gravity is not a part of the Standard Model, but it is thought that there may be particles called gravitons which are the excitations of gravitational waves. The status of this particle is still tentative, because the theory is incomplete and because the interactions of single gravitons may be too weak to be detected. ~ wiki At AZ, everything is frozen, there can be no excitation of particles. No excitation, no force carriers, the Standard Model breaks down. In cosmology there are what is called 'Voids'. Voids are black areas of the Universe where 'no data' is collected. From a science view, Dark is void. The Boötes void is one of the largest-known voids in the Universe, and is referred to as a supervoid. The eye registers dark as black. Since the eye can't resolve the entire spectrum it sees dark as no data. The Hubble Deep Field proves the dark one sees when looking at the Universe is not void. Thus, dark is a matter of relativity.

How is a void different than dark? Star>>>>>>>>>>>VOID>>>>>>>>>>>>>>Detector/Eye Void volumes can be detected/measured by observing the light from stars on the other side of the void. The void is not a black section of space. It is a volume of empty space. Simple example; You have two stars that appear side by side. One star measures at 1 lightyear away and the other star measures at 100 lightyears away. The measurement of the distance of light sources determines the shape and volume of the void from our perspective.

But for shadow to cast upon anything you need light to reach out there first

There is a difference between shadow and dark. We see because our eyes detect the spectrum of light that reflects from a mass. The brightest objects are objects which reflect on the faster wavelengths of visible light. The darkest objects absorb the faster wavelengths of visible light. An object that absorbs (does not reflect) all visible light will appear completely dark because our eyes do not detect any visible light. Shadow is an occlusion (blockage) of light from a mass. Our detectors can detect light wavelengths beyond the capacity of our eyes. Both in the ultraviolet and the infrared. An object that appears dark to our eyes may be visible using these specialized detectors. Using our detectors we can see far past the ultraviolet and infrared. However, there may be spectrum we can not detect yet. Those objects would appear dark to our eyes and our specialized detectors. Everything we can see or detect is a reflection prism of the whole. Dark is the absence of reflected light, nothing more.

But the dark under your bed hides bogeymen, and when you turn the light on, they disappear, but are still there.

A dark gin and a light tonic. And a shady video. You've got it spot on Ladywind.

Sounds hinky. There is no dark side of the moon, really. As a matter of fact it's all dark. "Breathe deep the gathering gloom, Watchlights fade from every room. Bedsitter people look back and lament, Another day's useless energy spent. Impassioned lovers wrestle as one, Lonely man cries for love and has none. New mother picks up and suckles her son, Senior citizens wish they were young. Cold hearted orb that rules the night, Removes the colours from our sight. Red is grey and yellow white. But we decide which is right. And which is an illusion???
