The statement that does NOT fit the model of the Big Bang and the subsequent changes in the universe is:
**The galaxies are moving closer together as time progresses.**
This statement is incorrect because, according to the Big Bang theory and cosmological observations, the universe has been expanding since the Big Bang, and galaxies are generally moving away from each other, not closer together.

The correct definition of dark energy from the provided options is:
**Energy that humans cannot observe directly.**
Dark energy is a form of energy that is thought to permeate all of space and is responsible for the accelerated expansion of the universe, but it cannot be observed directly, as it does not emit or interact with electromagnetic radiation like light.
