I’m having a little trouble wrapping my head around this. The only thing I can sort of think of is that I know these units are somewhat related to what the conditions of the universe were a the Big Bang, so perhaps that’s why?
In: Physics
The hotter something is, the shorter the wavelengths it can emit get (like how if you heat up metal it starts at red (700nm) then yellow (600nm) then finally white (red/yellow + blue at 400nm))
The Planck temperature is how hot something needs to be to emit radiation with a wavelength of one Planck length.
