By your assertion, are you also implying that the universe will live forever. It is a fact as of astronomical observations, as a consequent of the expansion, that the universe is cooling down. Its measureable temperature is becoming less and less as centuries progress. Eventually, the temperature will reach absolute zero. What then?
Back to the title of this thread, the total number of souls in the universe (another way of saying energy conservation) will remain constant no matter what is the fate of the universe. In an isolated system such as our universe, no mass or energy crosses the boundary of its control volume. So mass and energy are both conserved. The volume is expanding but the temperature is decreasing validating the principle of energy conservation. At absolute zero of temperature, there is no more reason or incentive or motivation for the universe to expand farther.
