Not necessarily. Two possibilities:
- If the universe is expanding (and there is no reason why some of the
red shift might not be due to movement) then the universe cools to offset that.
- If old matter is crushed out of existence in black holes then there is
no net gain and the universe can be the temperature it is. Conservation of
energy/mass becomes just a handy guide if you have stuff popping into
existence in the great voids, or everything all at once at the beginning.
