Cold is a relative state. It does exist, however and can be quantified and measured.

What is the source of darkness and cold since the sun is the source of heat and light?
We're modestly familiar with the source of heat and light. And we know that heat and light both exist and are real. Cold and darkness do not exist. They merely describe the lack of heat and light, respectively.
Does heat chase cold?
Heat is real. Cold is just a human concept for it's opposite. Cold does not exist.
Does cold travel from the surface to your hand or does energy travel from your hand to the cold surface?
Energy travels from your hand to the cold surface. Cold is merely the relative absence of heat.
Does mints cool things down or is merely a sensation?
Yes it is merely a sensation.Menthol has a property to stimulate the cold sensitive receptors in skin and mucus membranes producing feeling of coolness.This is just like the opposit that happen with pepper which stimulate heat receptors producing feeling of warmth without actually causing heat change...
Do heat and cold flow between objects?
Technically the answer to your question is no. Heat does indeed flow between objects, but cold does not because it doesn't really physically exist. "Cold" is just a lower level of heat.

Why is it incorrect to say the insulation 'keeps out the cold'?
Because in science, cold doesn't exist. You can't make cold, you can only remove heat. But in human language we've made words to describe the absences too. Dark is the absence of light. Cold is the absence of heat. Vacuum is the absence of all material. So insulation can't keep the cold out, since the cold doesn't exist. What you can do though is keep the heat in. Heat is a real thing. You can make heat.

Do cold radiation waves go down?
There is no such thing as cold radiation. Cold is nothing in itself; it is merely the absence of heat - or just less heat. Heat, like light, radiates, but cold, like darkness, does not.What you may think of is cold convection; i.e., the fact that cold air will sink and warm air will rise. This effect is often confused as being 'cold radiation'.
What numbers fill the spaces 150 SPACE 84 SPACE 42 SPACE 30 and if possible what is the formula?
"what is the wether like in space? always hot? manley cold? both?" I assume this was posted as a joke, because it was posted as an answer not a question, but always cold. In a way cold does't actually exist, it is just an absence of heat. If there is no gases, in space to be hot, then there is an absence heat, or cold.
Does cold radiate from Neptune?
No. Cold cannot radiate, only heat can. This is because cold is not a thing unto itself but is simply the relative absence of heat. While it is very cold, Neptune actually radiates more heat than it receives from the sun. If it were not for this it would be even colder.
