why is space cold when everything generates heat? expanding: why isn’t the expansion of space creating heat at the edges?

Goodness that’s a bit to unpack there…
Simple answer: you have temperature and volume. Increase the volume, you lower the temperature.
Ok, now have a thing expand for 13.8 billion years (at a fairly rapid pace) and you’ve diluted the heat, therefore reducing the temperature.
Now check *why* the cosmic background temperature is what it is.
