Explain what balloon + dots represent
The dots represent galaxies and the balloon represents the universe.
Which letter(s) move the farthest from M? Which moved the least?
D dot moved the farthest from M, while A stayed closest.
Summarize the trend: movement of galaxies. Related to distance from M
The galaxies that were closer to M move less than the ones that we far away from M
How does this experiment model what is occurring in our expanding universe? In what ways does the balloon not represent the universe?
This lab models how the galaxies move apart as the universe expands. The balloon doesn’t represent the universe because the ballon expands when air is blown into it, which is not the same for our universe
