Dark energy is the source of 25 percent of the mass of the universe.
Dark energy is the source of 25 percent of the mass of the universe.

Through dark energy, the universe is expanding at a faster and faster rate.
Through dark energy, the universe is expanding at a faster and faster rate.

Because of dark matter, gravitational interactions cause galaxies to develop.
Because of dark matter, gravitational interactions cause galaxies to develop.

Without dark energy, structures in the early universe would never have developed.

Answer 1

The two correct statements that relate dark matter and dark energy to the Big Bang theory are:

1. Through dark energy, the universe is expanding at a faster and faster rate.
   This statement is correct because dark energy is thought to be responsible for the accelerated expansion of the universe.

2. Because of dark matter, gravitational interactions cause galaxies to develop.
   This statement is also correct because dark matter contributes to the gravitational pull necessary for the formation and development of galaxies.

The other statements contain inaccuracies; specifically, dark energy does not account for a mass fraction (it is more about the energy density), and the evolution of structures in the universe relies on gravitational interactions rather than the absence of dark energy.
