 In Lab 

In the lab this week my table group and I presented our slideshow on the past, present, and future of space travel. We also learned from other groups about the origin of the universe, the lifecycle of a star, galaxies, the origin of the earth, and black holes. All of these sections we learned about from different groups were the big questions for this week in lab.

Thursdays Lecture 

In Thursday's lecture, we talked about how the universe was theoretically created through expansion and not an explosion, subatomic particles inflated to an extremely large size in a fraction of a second and that is what caused our universe to form. We also discussed the topic of nuclear fusion and through this process, stars can make up to iron on the table of elements, we also dove deeper into the topic of Red giant stars and how they burn fuel faster based on the fact that they have more mass compared to stars that have smaller mass so they bun slower. I thought that it was very interesting how scientists figured out we as humans are made of stardust, so if that is true that means we are technically all stars! In the lecture, we also talked about black holes and how they are located in the center of most galaxies. Black holes are what keep planets on the same plane because black holes provide a strong gravitational pull. 

Pressbook 

One of the items I found to be helpful in the pressbook was the timeline of the universe. In class we have been talking a lot about different timelines and when scientists theorized things happened and all the dates have been making me confused so the timeline is very helpful. 

In the lecture, I was confused about what the three primary shapes were talking about and the Pressbook helped me learn that the three primary shapes are talking about the different shapes of galaxies. The three primary shapes are spiral, elliptical, and irregular, and because we live in the milkway we live in a spiral galaxy.  

Questions and concerns

I am still very confused about how we determine where our shadows are going to be located based on the sun. Due to the test coming up, I would like to learn more and gain an understanding of how to determine where my shadow will be located. I am also still slightly confused on the understanding where the location of the moon will be so I would like to talk more about that as well.
