But if you’re even more pedantic, it is true. The ocean is colder than space. Interstellar space is very cold, but space near the Sun—and near Earth—is actually incredibly hot! The reason it doesn’t seem that way is that in space, the definition of “temperature” breaks down a little bit. Space seems cold because it’s so empty. Temperature is a measure of the average kinetic energy of a collection of particles. In space, individual molecules have a high average kinetic energy, but there are so few of them that they don’t affect you.
