The two correct statements that accurately differentiate between dark matter and dark energy are:
-
Dark energy is the cause of the acceleration of the universe, while dark matter is the cause of the formation of structures.
-
There is much more dark matter in the universe, by mass.
These statements correctly reflect the roles that dark matter and dark energy play in the cosmos. Dark energy is associated with the acceleration of the universe's expansion, while dark matter contributes to the gravitational effects that lead to the formation of galaxies and other structures. Additionally, dark matter is more prevalent in terms of mass compared to dark energy.
