 Despite this rise in complexity, current observations suggest the universe will likely expand forever rather than recollapse. The discovery of "dark energy," a mysterious repulsive force that constitutes the majority of the universe's energy density, indicates that cosmic expansion is accelerating. As galaxies drift farther apart and stars eventually exhaust their nuclear fuel, the universe is expected to become cold, dark, and simple, eventually reaching a state of maximum entropy. In this probable future, known as the "**Big Freeze**," energy gradients will flatten out, rendering the formation of any further complexity impossible, bringing the grand narrative to a silent, frozen conclusion. Despite this rise in complexity, current observations suggest the universe will likely expand forever rather than recollapse.
