Galaxies are Born
Verified. Empirically supported and rationally deduced.
Expanding Universe
Galaxies formed early in cosmic history, within a few hundred million years of the Big Bang. This shows that structure emerged quickly from an initially simple universe. Observations confirm that gravity wasted little time turning primordial gas into organized systems, even before features we now consider typical. Such as central supermassive black holes commonly found in galaxies.

“We are all connected to each other biologically, to the Earth chemically, and to the rest of the universe atomically.”
- Carl Sagan

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.

How many galaxies can we see with the naked eye?
Night Sky
Early humans made sense of the cosmos using what they could see: the Sun, Moon, and five wandering planets. That limited view shaped mythology, calendars, and meaning for millennia. They would be stunned to learn that a few of the stars they documented were actually galaxies.

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.
The Fermi Paradox is Too Anthropocentric
