Answer:
I have answers 1-5
1. How does the density and distribution of your “stars” change as the balloon expands?
As the balloon expands the stars would be farther apart and the number of stars would increase.
2. How does your expanding balloon model represent an expanding universe?
As the balloon gains more air it expands like an expanding universe as it gathers more mass.
3. What are some shortcomings of using this model as a replica of universe expansion?
You have to manually make the model bigger instead of a random increase like a computer model would, which would make the model more realistic.
4. How does the model you created help to show that the Steady State theory is inaccurate?
The steady state theory states that the universe is expanding over time but remains unchanged. The balloon model disproves the steady state theory by showing the expansion of the universe(balloon) and its galaxies(dots) which shows us the universe has changed by getting larger and everything is getting further apart.
5. Suggest a way that a scientist could create an even more accurate model of universe expansion.
You could make a computer model. This kind of model would allow your universe to increase on its own and possibly add more features like new forming galaxies to make it more realistic.
