The Origins of the Milky Way and Andromeda

Gravity is inexorably pulling us together and we will form some big combined galaxy I don't know what you call it like the Andromeda way or milky Andromeda. The dwarf galaxies that formed Andromeda they sort of formed separately and then later came together to make bigger galaxies. As we'll talk about later in the podcast the dwarf galaxies We don't really understand why there aren't more of them.
