#201 – Konstantin Batygin: Planet 9 and the Edge of Our Solar System

Jul 19, 2021

In this engaging discussion, Konstantin Batygin, a planetary astrophysicist at Caltech, dives into the search for Planet Nine and the mysteries of our solar system. He unravels the intriguing dynamics of the Kuiper Belt and Oort Cloud, and speculates about the existence of alien civilizations based on their waste. Batygin also reflects on humanity's future in cosmic exploration and the philosophical implications of space commercialization. With humor and insight, he emphasizes the complexity of celestial interactions and our place in the universe.

Episode notes

INSIGHT

Simulating Gravity

Two-body gravitational problems are solvable, but three-body problems are chaotic and unpredictable.
Simulating the entire solar system from scratch is futile due to this chaotic nature.

INSIGHT

Schrödinger Equation for Astrophysical Disks

The Schrödinger equation, while used in quantum mechanics, is fundamentally a wave equation.
It can model waves in astrophysical disks because their behavior is analogous to wave functions.

INSIGHT

Planet Formation

Solid particles in protoplanetary disks clump together to minimize aerodynamic interaction with gas.
These clumps grow until they collapse under their own weight, forming planets' building blocks.
