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.

FAQ
How many more Pluto-like dwarf planets are in our solar system?
Definitions
Pluto isn’t an oddball—it’s a preview. Models suggest hundreds of similar dwarf planets in the Kuiper Belt, and potentially vast numbers more in the Oort Cloud. The deeper lesson is scale: our solar system is far larger, richer, and more resource-dense than everyday intuition suggests.
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.
The Fermi Paradox is Too Anthropocentric
