Which of the following statements provide evidence to support the big bang theory? Select the two correct answers.(1 point) Responses The universe began as a very high density singularity. The universe began as a very high density singularity. Small spiral galaxies become larger elliptical galaxies when they collide. Small spiral galaxies become larger elliptical galaxies when they collide. Dark matter makes up the majority of matter in the galaxy. Dark matter makes up the majority of matter in the galaxy. The ratios of hydrogen and helium in the universe match those of the early universe.
The universe began as a very high density singularity.
The ratios of hydrogen and helium in the universe match those of the early universe.
The two statements that provide evidence to support the big bang theory are:
1. The universe began as a very high-density singularity.
2. The ratios of hydrogen and helium in the universe match those of the early universe.
To determine which of the statements provide evidence to support the Big Bang theory, we can analyze each option:
1. The universe began as a very high-density singularity: This statement is a key aspect of the Big Bang theory. According to this theory, the universe originated from a dense and hot singularity, expanding and cooling over time.
2. Small spiral galaxies become larger elliptical galaxies when they collide: This statement is unrelated to the Big Bang theory. It describes a process observed in galaxies, but it does not provide evidence for the initial origin of the universe.
3. Dark matter makes up the majority of matter in the galaxy: While dark matter is an important component of the universe, it is not directly related to evidence for the Big Bang theory. Dark matter is inferred from its gravitational effects on visible matter, but it does not provide evidence for the initial expansion of the universe.
4. The ratios of hydrogen and helium in the universe match those of the early universe: This statement aligns with the Big Bang theory. According to the theory, the early universe contained mostly hydrogen and helium, with small traces of other elements. Observations show that the ratios of hydrogen and helium in the universe today match those predicted for the early universe.
Based on the explanation above, the two statements that provide evidence to support the Big Bang theory are:
- The universe began as a very high-density singularity.
- The ratios of hydrogen and helium in the universe match those of the early universe.
