Вот надо эту строчку из википедии вписать куда-нибудь для людей типа меня, которые учебниками по физике играли в настольный теннис:
"The highly diluted gas in this layer can reach 2,500 °C (4,530 °F) during the day. Even though the temperature is so high, one would not feel warm in the thermosphere, because it is so near vacuum that there is not enough contact with the few atoms of gas to transfer much heat. A normal thermometer might indicate significantly below 0 °C (32 °F), at least at night, because the energy lost by thermal radiation would exceed the energy acquired from the atmospheric gas by direct contact."
"При давлении в ~50 атмосфер и температуре ~10 С вы обнаружите, что жидкость может плавать на газе (а именно, сплав NaK на сжатом ксеноне)" - вот за этот ответ отдельное спасибо!

Заметил описку:
вспомним, что вакуумом называется среда с длиной пробега молекул меньшей, чем её (среды) размеры.
Должно быть "больше или равно"
