He provided a quick historical overview of three "game changers" that were fundamental to what he called the "dwarf planet revolution": the discovery that oceans are common on other bodies in our solar system, the discovery of the Kuiper Belt of icy objects that show what the solar system looked like early in its history and the discovery of small worlds such as Pluto most of which were not found until the early 21st century.
