Are you honestly saying "there's no use in expecting each word to be defined correctly?" In that case, you are incarcerated.
Actually most people do not find it difficult to use existing words to express their thoughts.
I say it again, that was a quote (from http://www.luisprada.com/protected/The_Sun_Is_Cold_I.htm) and not my words.
I try to speak plainly. Here again:
The space is much colder even when one is infront of the earth facing the sun.
High up in earth's atmosphere, snow forms on the tallest mountains. Perhaps, we can hear the points of view from skydivers, hot air balloonists, etc. what they observe.
It is obvious though that as you go higher in the atmosphere, temperature drops. Temperature can drop low enough that water vapor in the air begin to form ice crystals that become snow...
Halley's comet observed to be made of ice and dust could have not survived several trips around a giant ball of nuclear furnace.
