The correct match between ideas related to the formation of the universe is:
greatest percent of mass of universe — dark matter
The correct match between ideas related to the formation of the universe is "structure forming in the early universe — dark matter."
To understand why this is the correct match, let's break down the options:
1. Glowing nebulae — dark energy: While glowing nebulae are indeed a phenomenon observed in the universe, they are not directly related to dark energy. Dark energy is a hypothetical form of energy that scientists believe is responsible for the accelerating expansion of the universe.
2. Mass-energy equivalence — dark matter: The concept of mass-energy equivalence, famously described by Einstein's equation E=mc², relates to the idea that mass and energy are interchangeable. While the concept of mass-energy equivalence is important and explains the relationship between mass and energy, it is not directly related to dark matter.
3. Structure forming in the early universe — dark matter: This is the correct match. Dark matter is a type of matter that does not interact with light or other electromagnetic radiation, making it invisible. However, its gravitational effects can be observed. Scientists believe that dark matter played a crucial role in the formation of large-scale structures, such as galaxies and galaxy clusters, in the early universe.
4. Greatest percent of mass of the universe — dark matter: While dark matter does indeed make up a significant portion of the total mass of the universe (around 27%), it is not the correct match for the statement "greatest percent of mass of the universe." The majority of the mass of the universe is actually composed of dark matter and dark energy combined, with normal matter (everything we can see) making up only a small fraction.
In summary, the correct match between ideas related to the formation of the universe is "structure forming in the early universe — dark matter."
