Chapter 1 Quote Attribution Clarification
Great ideas often exist before and beyond any single speaker. The insight that humans are biologically, chemically, and atomically connected to the universe appears across science and philosophy, voiced by thinkers in different ways.

“We are all connected to each other biologically, to the Earth chemically, and to the rest of the universe atomically.”
We Are Stardust
Carl Sagan had many similar quotes to this.
Carl Sagan reminds us that we are intimately connected to the universe. The particles that form our bodies are borrowed from a cosmic pool of just 17 particles and four forces. Even more humbling, the molecules within us were forged in the hearts of stars, linking us directly to the vast cosmos that surrounds us.

When did we discover stars are mostly made of hydrogen and helium?
The Stuff of Stars
Scientific progress often comes from questioning assumptions hidden in plain sight. For decades, astronomers mistook spectral strength for elemental abundance, projecting Earth’s composition onto the cosmos. Payne’s insight—that ionization, not quantity, shaped stellar spectra—revealed a universe far simpler and more alien than expected, and far richer in understanding.
Cosmology
The Universe
Our origin story.

The universe is a self-reconfiguring machine, with nothing being created from the void nor destroyed to nothing. At the core of reality are four forces guiding 17+ particles. We see these particles combine into atoms and molecules. Those molecules bundle into materials, and those materials evolve into life.
