In Episode 4 we look at the concept of wormholes, how they derive from General Relativity, the various different types and theories, and some under-considered uses of wormholes. We'll also discuss some myths and misunderstandings of the concept.

FTL04 - Wormholes

Episode 5 of the Habitable Planets Series takes a look at double planets and what sort of conditions would prevail, or need to prevail, for them to be Earth-like. As well as the Rocheworld, a special case of Double Planets where the two planets either share an atmosphere or have even begun to merge together.

Note: make sure to set units of both bodies to Earth Mass and period to hours or days if trying to look at double planet cases.

HP05 - Double Planets And Rocheworlds

This episode begins our look at solutions to the Fermi Paradox - the question of why the Universe appears empty of intelligent life besides ourselves - by looking at some of the reasons why life may simply be very uncommon. Before we can contemplate what might be special about Earth, we first need to consider what might be special about our region of space, and even our epoch of time, or our Universe itself.

Great Filters: Space & Time (Narration Only)

We continue our look at possible explanations why life may be very rare in the Universe by examining our planet itself, and looking at which of its characteristic might be important to intelligence developing and how improbable those traits are for a given planet in a given solar system.

Fermi Paradox Great Filters: Rare Earth (Narration Only)

We conclude our look at possible explanations why life may be very rare in the Universe by looking at the evolutionary pathway to intelligence and the hurdles between life starting on a planet and migrating off of it.

Rare Intelligence (Narration Only)

We contemplate colonizing planets, but what about the stars themselves?

Containing virtually all the mass and resources of the solar system, the Sun, the Sun is the ultimate asset for a growing interplanetary civilization. While typically assumed too hot to touch and so out of our reach, we will challenge that notion today.

Colonizing the Sun (Narration Only)

The option of using floating platforms, balloons, or cargo air planes to launch rockets into space and save fuel is often discussed but rarely employed. Today we'll look at stratostations, rockoons, and other suggested methods for getting into space using these methods.

Sky Platforms (Narration Only)

The Fermi Paradox, the big question of where all the aliens are, has many proposed solutions focusing on what might lower the odds of intelligent species arising on another world, or what might end technological civilizations or cause them to go unseen by us and our SETI efforts. But what if intelligence rarely leads to technological civilizations in the first place? Could there be countless planets in our galaxy occupied by species who never came to value technology?

The Fermi Paradox: Rare Technology

The Fermi Paradox asks why we don't see any alien civilizations with our SETI efforts. The Late Filters are common solution suggested, that intelligent species may often arise but either destroy themselves or unwilling or incapable of interstellar travel to reach new worlds and colonize the galaxy.

The Fermi Paradox: Late Filters

The  Zoo Hypothesis is a Fermi Paradox solution that assumes extraterrestrial civilizations can't be detected by our SETI efforts because they keep our whole world in an Alien Zoo.
