Answer 1

According to measurements made by the Wilkinson Microwave Anisotropy Probe (WMAP), dark energy is by far the most plentiful material in the universe, making up about 68% of the total energy density of the universe. Therefore, the correct response is:

dark energy

Answer 2

The
of dark matter causes baryonic gas and dust to
.

Answer 3

The gravitational pull of dark matter causes baryonic gas and dust to collapse into structures.

This influence of dark matter is essential in the formation of galaxies and larger cosmic structures.

Answer 4

The (gravity)(electromagnetic radiation)
of dark matter causes baryonic gas and dust to (break apart) (clump together)

Answer 5

The gravity of dark matter causes baryonic gas and dust to clump together.

Dark matter's gravitational influence plays a crucial role in the formation of galaxies and the large-scale structure of the universe.
