During our conversation, we cover: \u2013 What are invisible galaxies? \u2013 How do we find distant galaxies that we can\u2019t see via their own light? \u2013 What are redshift distances? \u2013 How does looking at neutral hydrogen emissions help show distances of galaxies? \u2013 How are multiple galaxies detected along the same line of sight?
