In this seminar to mark the 20th anniversary of the founding of the Port Philip U3A, Dr Prentice will discuss various new discoveries about our Solar system that have been made since 2013, when he gave the 10th anniversary seminar. The discoveries have come about as a result 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 the speaker to test his Modern Laplacian Theory of 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. Dr Prentice also correctly predicted that Arrokoth’s surface would be smooth and crater-free and have no water ice. In this illustrated talk, he will explain the workings of the theory and why it does such a good job predicting the Solar system’s physical and chemical makeup.
The speaker is Dr Andrew Prentice from the School of Physics & Astronomy, Monash University. Dr Prentice gave the very first U3A Port Phillip Saturday Seminar, then the Saturday Seminar for our 10th anniversary and, now, the Saturday Seminar for our 20th anniversary.
Over the past 50 years, Dr Andrew Prentice has developed a new theory for how our Solar system was formed.
Andrew has spent most of his academic life at Monash University. He is presently an affiliate of the Monash School of Physics and Astronomy. He is an honorary lifetime member of the Astronomical Society of Victoria and a fellow of the Astronomical Society of Australia.
Although his ‘Modern Laplacian Theory’ theory sits outside mainstream thought, he has used it to make many successful predictions regarding the physical structure and chemical makeup of our Solar system. The opportunity to test these predictions has come about through NASA’s program of interplanetary spacecraft exploration, including most recently the New Horizons spacecraft visit to the Pluto system and to the Kuiper Belt object Arrokoth.
Heather Wheat is the seminar facilitator. She also was a founding member of U3APP and organised the inaugural seminar.
