Which statement is a part of the Big Bang Theory?
O the universe began as a very high density singularity
O Small spiral galaxies become larger elliptical galaxies
O Dark matter makes up the majority of matter in the galaxy.
O The chemical makeup of the universe has changed dramatically
O the universe began as a very high density singularity
The statement that is a part of the Big Bang Theory is: "The universe began as a very high density singularity."
The statement that is a part of the Big Bang Theory is: "The universe began as a very high-density singularity."
To arrive at this answer, we need to understand the key concepts of the Big Bang Theory. The Big Bang Theory is the prevailing scientific explanation for the origin and evolution of the universe. It states that approximately 13.8 billion years ago, the entire universe was condensed into a high-density singularity. This singularity then underwent a rapid expansion, creating space, time, and all matter and energy in the universe.
Now let's go through the given statements and see which one aligns with the Big Bang Theory:
1. "The universe began as a very high-density singularity" - This statement directly refers to the fundamental concept of the Big Bang Theory. It states that the universe originated from a highly compressed and dense state, which then expanded.
2. "Small spiral galaxies become larger elliptical galaxies" - This statement is unrelated to the Big Bang Theory. It refers to galactic evolution, which is not a direct part of the initial singularity and early expansion of the universe.
3. "Dark matter makes up the majority of matter in the galaxy" - Although dark matter is an important component of the universe, this statement does not specifically relate to the initial conditions and expansion described by the Big Bang Theory.
4. "The chemical makeup of the universe has changed dramatically" - While the chemical makeup of the universe has indeed changed over time, this statement does not specifically address the initial singularity and rapid expansion described by the Big Bang Theory.
Therefore, the statement that aligns with the Big Bang Theory is: "The universe began as a very high-density singularity."
