Wouldn’t it be the opposite? Because with nothing to impede the heat dissipation, wouldn’t it dissipate faster instead of slower?
In: Physics
Because heat is the measure of the average kinetic energy of the molecules in a substance.
The best way for them to lose that energy is to bump into something else and transfer it to that substance (so long as what it is bumping into has less energy). In space there is nothing for the molecules to bump into, so they can’t transfer the energy. The only other method they have to lose the energy is to radiate it away as light. This removes the energy at an extremely slower rate than physically bumping into something else.
