Question

how did dark matter affect the development of structures in the early universe? (1 point)
it cooled pockets of gas to form nebulae.
it became part of black holes.
it seeded the development of quasars.
it seeded the development of galaxies.

Explanation:

Dark matter has strong gravitational pull. In the early universe, its gravitational attraction pulled ordinary matter (gas) together, creating the dense seeds that grew into galaxies. The other options are incorrect: dark matter does not cool gas to form nebulae, it is not primarily part of black holes, and it does not seed quasars directly (quasars are related to supermassive black holes in galaxies, which formed from the galaxy seeds dark matter created).

Answer:

D. It seeded the development of galaxies.
