but if you did use thermometer in space it would eventual read 2.73 kelvin right? so whats the issue? and also for a space based server it would have to deal with the energy coming from the sun
what thermometer would you use to measure the temperature of space?
There is no matter.
It's cold there because there isn't anything there.
So there is nothing to conduct or convect the heat away.
It's like a giant vacuum insulated thermos.
Is putting data centers in thermos' a good idea?
