>>12707005Entropy is a measure of how distributed the energy is. Maximum entropy means energy is distributed evenly across the entire system. If it's not distributed evenly, then energy tends to flow from higher level to lower level until it *is* distributed evenly (this is what "entropy always increases" / 2nd law of thermodynamics means). Once it is distributed evenly, there is no more reason for energy to move from one place to another, hence it sits still.
Basically life is a mechanism to channel energy from higher level to lower level. You eat food (high energy) and shit it out (low energy). The food comes from plants and animals (which eat plants) while plants get their energy from the sun. Therefore you're basically eating the sun. Without the sun, all energy on earth would eventually distribute itself equally and nothing would have a reason to move anymore, so everything would die. But because the Sun keeps blasting energy at us, we keep getting more of it to distribute (hence keep us alive).
Eventually sun will radiate all its energy and it would get distributed evenly across the cosmos.
If the universe lives long enough, all energy in the universe would find its lowest level and the universe would die a heat death.
