See the Pattern | Is the Solar System an Outlier in Galactic Chemistry? @SeethePattern | Uploaded May 2024 | Updated October 2024, 5 days ago.
In this video we will explore the vast expanse between stars, the interstellar medium (ISM), where matter and energy intermingle to form the raw materials for stellar birth and the repository for elements synthesized by stars. Over time this space should become filled with heavier elements but a perplexing discovery emerges: despite expectations, the ISM appears to be lacking in certain heavier elements compared to our solar system. What are the implications for our understanding of stellar evolution and chemical enrichment.
