I want to know the answer to the following question:
What states that energy tends to become more evenly spread out across the universe?
All the background I'm provided with is that "The second law of thermodynamics states that energy (and matter) tends to become more evenly spread out across the universe: to concentrate energy (or matter) in one specific place, it is necessary to spread out a greater amount of energy (as heat) across the remainder of the universe ("the surroundings").[note 3] Simpler organisms can achieve higher energy efficiencies than more complex ones, but the complex organisms can occupy ecological niches that are not available to their simpler brethren.". Is that enough to answer the question?
Answer: yes
