What happens to the energy when the universe dies out?

  1. Jul 29, 2014 #1
    What happens to energy when the universe dies out? I understand how the law of conversation on energy works within a closed system(somewhat) but what about on the universal scale? If dark energy is accelerating planets outward isn't energy increasing or just staying proportionate?

    Welcome to PF!

    If you consider the universe as a closed system and consider the second and third laws of thermodynamics it will tend to go from a higher energy state to a lower one then I suspect the energy will be dissipated across the total expanse of spacetime.
