The universe was denser previously than it is now.
The universe was hotter previously than it is now.
The galaxies are moving closer together as time progresses.
The universe is continuing to expand, even after the Big Bang.
The galaxies are moving closer together as time progresses.
The statement that does NOT fit the model of the Big Bang and the subsequent changes in the universe is: The galaxies are moving closer together as time progresses.
To determine the statement that does NOT fit the model of the Big Bang and the subsequent changes in the universe, we need to understand the basic concepts of the Big Bang theory.
According to the Big Bang theory:
1. The universe was denser previously than it is now: This statement is consistent with the model. The Big Bang theory states that the universe began as an extremely dense and hot singularity.
2. The universe was hotter previously than it is now: This statement is also consistent with the model. As the universe expanded, it cooled down over time.
3. The galaxies are moving closer together as time progresses: This statement does not fit the model. In reality, the galaxies are moving further apart due to the expansion of the universe. This observation is supported by Hubble's law, which states that the further a galaxy is from us, the faster it appears to be moving away.
4. The universe is continuing to expand, even after the Big Bang: This statement is consistent with the model. The expansion of the universe is an essential aspect of the Big Bang theory. It explains the observed redshift of distant galaxies and the cosmic microwave background radiation.
Therefore, the statement that does NOT fit the model of the Big Bang and the subsequent changes in the universe is "The galaxies are moving closer together as time progresses."
