Expanding Universe

1.
In this lab We used a used a balloon to model the expansion of the universe and how the galaxies within it spread. We labelled the neck of the balloon m (for Milky Way Galaxy) and the rest of the “galaxies” letters a to e, after blowing the ballon to three different sizes and measuring the distance between we could observe our results and look for a pattern that relates to space.
2.
In this lab the balloon represented the universe and showed how it expanded when blown into, and the dots would represent the galaxies within the “universe” and how they moved as the Galaxy expanded.
3.
Some trends in expansion distance I noticed is that the “galaxies” furthest away from M would move the furthest amount of distance from it. And that as the universe grows so does the space within it.
4.
I think this activity allowed for me to better understand how the universe works and how its contents expand with it. Some things I’m still curious about is, how the first thing was made (in the universe) if it was the first thing ever made, there is a lot of questions I have about this topic but This one I chose because it would answer a lot of the other ones.
