According to [[secular]] physicists, the heat death of the universe is one possible scenario for the final fate of the [[universe]]. It speculates that, over time, all [[energy]] in the universe will eventually be converted to heat energy, which will then be spread more or less evenly over all space in accordance with the second law of [[thermodynamics]]. With all energy so widely distributed, the universe will revert to an extremely cold state, and nowhere will there be a sufficient concentration of energy to sustain any physical activity or movement.
