glowing nebulae — dark energy
structures forming in the early universe — dark matter
structures forming in the early universe — dark matter
greatest percent of mass of universe — dark matter
accelerating expansion — dark energy
structures forming in the early universe — dark matter
The two correct matches between ideas related to the formation of the universe are:
1. Accelerating expansion — dark energy
2. Structures forming in the early universe — dark matter
The two correct matches between ideas related to the formation of the universe are:
1. Accelerating expansion — dark energy: This match is correct because accelerating expansion refers to the observation that the universe is expanding at an increasing rate. Dark energy is a hypothetical form of energy that is believed to be responsible for this accelerating expansion.
3. Structures forming in the early universe — dark matter: This match is correct because structures, such as galaxies and clusters of galaxies, began to form in the early universe due to the gravitational influence of dark matter. Dark matter is an invisible and unidentified form of matter that does not interact with light or other electromagnetic radiation, making it difficult to directly detect.
The other options, glowing nebulae and the greatest percent of mass of the universe, are not correct matches for the formation of the universe. Glowing nebulae are not directly related to dark energy, and the greatest percentage of mass in the universe is attributed to dark matter, not dark energy.
