Isolation does not lie in the cold!! to

Why is it cold in space? The vacuum is almost perfect heat insulation. Space vehicles are more likely to suffer from overheating.

I don't know what you're being taught now, but when I was in school, the temperature in outer space was absolute zero, -273 degrees.

The temperature, what is it? The vacuum temperature" is an oxymoron. And in school a lot of things are simplified so that the brains of children do not load.

The vacuum temperature in space is about 3 K. Yes, the vacuum has a temperature (the same energy), which consists of the energy of the particles in the vacuum (yes, there are particles, the definition of physical vacuum), and the own temperature of quantum foam. At the same time, all this does not prevent it from being an almost perfect heat insulator (excluding radiation losses, of course).
Oh, what does the blue isolant do to people.
