Question

1. how does the galaxy movement theory support the big bang theory?

the big bang theory states that, over time, galaxies move and combine with other galaxies. scientists can observe this movement and note when planets join different galaxies.
the big bang theory states that the universe is shrinking. scientists can look back in time to galaxies beyond the milky way and calculate how long it will take them to shrink and move to their future destinations.
the big bang theory states that the universe does not evolve or change and that it has, in fact, stayed the same since its formation. scientists can study galaxies and see that they have not evolved or moved, which supports the big bang theory.
the big bang theory states that the universe is expanding. scientists can look back in time to galaxies beyond the milky way and calculate how long it takes the galaxies to expand and move to their present destinations.

Explanation:

1. Analyze the first option: The Big Bang theory is about the universe's expansion, not galaxies combining with planets joining galaxies. This is incorrect.
2. Analyze the second option: The Big Bang theory states the universe is expanding, not shrinking. So this is wrong.
3. Analyze the third option: The Big Bang theory says the universe is evolving (expanding) and changing, so the claim that the universe does not evolve or change is incorrect.
4. Analyze the fourth option: The Big Bang theory states the universe is expanding. Scientists looking at distant galaxies (which are like looking back in time) and calculating the time for galaxies to expand to their present destinations supports the idea of an expanding universe from a Big Bang origin. This matches the correct understanding.

Answer:

The big bang theory states that the universe is expanding. Scientists can look back in time to galaxies beyond the Milky Way and calculate how long it takes the galaxies to expand and move to their present destinations.
