Recent Discoveries in the Outer Solar System and their Implications for the System’s Origin
Held On Saturday 18 November
Dr Andrew Prentice
“Mathematician Dr Andrew Prentice is considered a world leader when it comes to explaining the formation of the solar system, though, as Andrew found out the hard way, when your ideas are bold and your calculations sharp, it can be hard to be taken seriously”.

What a coup for U3A Port Phillip to have had Dr Andrew Prentice present a fascinating account of his groundbreaking work on our solar system. Dr Prentice was invited to give the inaugural Saturday seminar in 2003 by U3APP founding member Heather Wheat. He later gave the 10th anniversary seminar and now the 20th anniversary seminar.
We heard that new discoveries have come about because of NASA’s New Horizons spacecraft flybys of Pluto and its family of moons, and of the tiny Kuiper Belt object Arrokoth. Until those flybys, very little was known about Pluto or its moons. Nothing was known about Arrokoth. The flybys provided a unique opportunity for Dr Prentice to test his Modern Laplacian Theory of The Solar System Origin.
This theory successfully predicted that Pluto’s crust was made mostly of methane ice and that Pluto’s largest moon Charon was once an ocean world. He also correctly predicted that Arrokoth’s surface would be smooth and crater-free and have no water ice.
Not only is Dr Prentice passionate about his research, but he is a witty and entertaining teacher.
Our thanks go to Dr Prentice and to Heather Wheat, seminar facilitator.
