But the universe looks fundamentally different at different times because
Dark Energy is accelerating things, so energy is not conserved at the
cosmological scale. It's still true that if things are in thermal
equilibrium then the amount of energy entering a region of space is equal
to the amount of energy leaving it, however that region of space is getting
larger so the energy in that region is getting larger because Dark Energy
is a mysterious property of empty space that is not well understood.
