Theia – Brian Isett
from Emergence Magazine Podcast
In this week’s story, biologist Brian Isett ponders the age-old question his young daughter will inevitably ask — Where did the Moon come from? — and uncovers how the Earth got Her seasonal song. He introduces us to Theia, the proto-planet that came crashing into the surface of our infant planet four and a half billion years ago, tilting the Earth on Her axis and birthing the Moon. This meeting ultimately shaped the passing of time, the movement of tides, and the cycle of the seasons as we have known them. With the seasons now changing in response to our neglect of the Earth, Theia offers a reminder that these rhythms have always evolved through relationship. Read the essay.
