Radiative cooling. When something gets hot, it begins to radiate that heat away - black body radiation.

Fucking hell - do you all think ISS is cooled by hopes and prayers?

Starlink V3 sats have to dump ~20kW of pure waste heat just to exist. Going from that to the stated 100kW is an engineering task, not some sort of impossible arcane rite.
