The dark universe, which constitutes over 95% of the cosmos, includes dark matter and dark energy, both of which are largely mysterious but crucial for understanding the universe beyond visible matter. Dark matter, making up about 25% of the universe's mass, influences gravitational forces, while dark energy, comprising about 70%, is believed to drive the universe's expansion.
