The correct answers are:
1) The ratios of hydrogen and helium in the universe match those of the early universe.
2) The universe began as a very high density singularity.
The correct answers are:
1. The ratios of hydrogen and helium in the universe match those of the early universe.
2. The universe began as a very high density singularity.
To determine which of the statements provide evidence to support the Big Bang theory, we can analyze each statement and see if it aligns with the underlying concepts of the theory.
1. "The ratios of hydrogen and helium in the universe match those of the early universe."
This statement aligns with the Big Bang theory because the theory states that during the early stages of the universe, the majority of matter was in the form of hydrogen and helium. As the universe expanded and cooled down, it allowed for the formation of other elements. Thus, the observation that the ratios of hydrogen and helium in the universe match those of the early universe provides evidence for the Big Bang theory.
2. "The universe began as a very high-density singularity."
This statement also supports the Big Bang theory. According to the theory, the universe began as an extremely hot and dense singularity. Over time, this singularity expanded rapidly and gave rise to the universe as we know it. Therefore, the statement that the universe began as a very high-density singularity is consistent with the Big Bang theory.
3. "Dark matter makes up the majority of matter in the galaxy."
While the presence of dark matter is indeed an important component in understanding the structure and evolution of the universe, it is not directly related to the Big Bang theory. Dark matter is hypothesized to exist based on the gravitational effects it has on visible matter, but its exact nature is still not fully understood. The Big Bang theory, on the other hand, primarily deals with the origin and early expansion of the universe, rather than the composition of galaxies. Therefore, this statement is not directly linked to evidence supporting the Big Bang theory.
4. "Small spiral galaxies become larger elliptical galaxies when they collide."
This statement addresses the dynamics of galaxy collisions, which is not specific to supporting the Big Bang theory. The Big Bang theory focuses on the expansion and origin of the universe and does not directly address the formation or interaction of individual galaxies. While galaxy collisions can lead to the transformation of galactic structures, it is not a direct piece of evidence supporting the Big Bang theory.
Therefore, the two statements that provide evidence to support the Big Bang theory are:
1. The ratios of hydrogen and helium in the universe match those of the early universe.
2. The universe began as a very high-density singularity.
