That's the part I don't get, RP. Why it would differ in the past or future if the mass is remaining proportionate to spatial expansion. Isn't the idea of a decrease in density based on mass being distributed over a larger and larger amount of space?

Like if we measure a meter-long piece of wood with a yardstick in the past and again in the future, the measurement is the same because the mass of both the wood and yardstick have increased as the universe expands.

Not to say that there is a violation in the conservation law, but that the vacuum energy is converted to mass due to acceleration.
