“Thanks to the fact that the Earth isn't a perfect sphere, and invoking a bunch of Newtonian physics, you can deduce that our planet wobbles, too, taking roughly 26,000 years to trace out a small circle on the sky, a phenomenon known as precession.”
About This Quote
This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation.
Earth's axis wobbles over 26,000 years, a motion called precession, due to its imperfect shape and physics.
In simple terms: Earth wobbles slowly because it's not a perfect sphere.
Key Takeaway
Consider the impact of precession on climate and astronomy.
