no cold does not exist all cold is, is the lack of heat or lack of movement of atoms in an object
The above answer makes the logical argument that is widely accepted. Something seems wrong about it though. Roughly asked---if there are no atoms or photons, is there no heat? We are saying that if it can't be measured, there is nothing there. But what if there is something there that we can't see, or detect? We just held an antimatter hydrogen atom still for a tenth of a second at least today. Antimatter is supposed to take up half of our universe. Is is hot? Apparently not, because they had to create conditions which were close to absolute zero to hold that bugger still.
Cold dose not exist it is the absence of heat. Man has made up this term zero being no heat at all. It is the law of Physics.
Heat is real. Cold is just a human concept for it's opposite. Cold does not exist.
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.
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.
Such cold temperatures - a fraction of a microkelvin! - don't exist in nature. They can only be created artificially.

Cold is a relative state. It does exist, however and can be quantified and measured.
"Cold" is a relative term, like "high" or "fast". It does exist as a qualitative term but only for comparison. It doesn't exist as a concrete object.
It is too cold for liquid water to exist on the surface
Heat is real. Cold is just a human concept for it's opposite. Cold does not exist.
No. Venus is too hot for liquid water to exist.
it is to cold
yes they did
jellyfish have no blood and exist at the temperature of their surroundings, as do cold blooded organisms

It does not exist.
Mars is a planet that is too cold for liquid water to exist on its surface. Almost the entire surface of Mars is covered in ice.
No. Venus is far too hot for water to exist on its surface.
