Colonizing Space

The discovery of 2017 OF201 reminds us that even small worlds can hold vast potential — not just as frozen orbs, but as stepping stones for interstellar civilization.

New Dwarf Planet Discovered: A Minor Planet With a Major Future?

Mars may be humanity’s next great home—but it’s not the finish line. From floating cities above Venus to mining Mercury and the Asteroid Belt, to building bases on the Jovian moons and Titan, we explore which destinations might follow Mars and how each could shape our future in space.

After Mars - 8 Candidates For Where Humanity Should Go Next

Solar storms are inevitable; disaster isn’t. We explore the physics of flares and CMEs, historical extremes, and realistic defenses—detection, delay, and planetary-scale shielding—to weather the Sun’s worst days.

Solar Flares and Coronal Mass Ejections - Defending Earth from Our Own Star (Narration Only)

Could the origins of life on Earth trace back to a natural nuclear reactor? Long before humanity split the atom, nature itself may have done it first. In this episode, we explore the astonishing possibility that self-sustaining fission reactions—like the Oklo natural reactor in Gabon—once powered the chemical engines of creation. From radioactive geysers and mineral-rich pools to the first self-replicating molecules, we’ll examine how nuclear energy might have provided the spark that turned chemistry into biology. Along the way, we’ll connect this mystery to the Fermi Paradox, asking whether such rare, radioactive beginnings might explain why intelligent life seems so scarce in the universe. Join us for a journey that blends cosmic mystery, geochemistry, and the science of life’s origins.

Colonizing The Outer Solar System

This episode begins a three-part series focusing more on the specifics of colonization including human aspect of it. We lay the groundwork by looking at colonies just in our solar system before moving off in episodes two and three to look at life on colony ships and then on interstellar colonies.

Life In A Space Colony Episode 1

This episode  is the second of a three-part series focusing more on the specifics of colonization including human aspect of it. Having laid the groundwork last time, we now ask ourselves what the ships carrying people to new worlds would be like, and what life aboard them would be like.
