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

By contemplating the idea of what true Kardashev 2 and 3 civilizations might look like, in the context of Megastructures, we re-assess the Fermi Paradox and come up with a new question, no longer "Why can't we see any alien civilizations?" but why we can see any stars in the night sky at all.

FP02 - Dyson Dilemma

This series takes a look at concepts for everything from Terraforming Planets and Interstellar Colonization to more down to Earth matters like Arcologies and Planet Wide Cities before examining using black holes as power sources for starships.We then leap into the far distance future at the end of time to examine civilizations surviving around black holes after all the stars have died out.

CS03 - The Impact Of Nuclear Fusion

A look at the Carter Doomsday Argument, which is uses a probabilistic argument and Anthropic Reasoning to estimate that humanity is running out of time.

EC03 The Doomsday Argument

In this Episode we examine the concept of the Simulation Hypothesis, which proposes a mathematical argument that we are almost certainly simulations running on a computer.

EC02 The Simulation Hypothesis

A look at concepts of transhumanism and life extension

EC01 Transhumanism And Immortality

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

H.P. Lovecraft is known as the father of the Cosmic Horror genre of fiction. The creator of Cthulhu and many other terrifying dark gods in his novels paints a bleak and decaying view of our world and the Universe. Today we'll examine what it might imply if that nihilistic and grim view of reality was correct.

Gods & Monsters: Space As Lovecraft Envisioned It (Narration Only)

As we pioneer our way out from Earth to other planets and eventual the stars, our concept of time will change in more ways than just different calendars. We'll explore how interstellar civilizations might cope with everything from relativity to life extension and how century long voyages and time lags of communication over millions of worlds might be managed.

Interstellar Civilizations and Time

In the future we might see the rise of minds entirely on computers, be it uploaded humans, transhumans, or artificial intelligence. But what would such an existence be like? Would they interact with our world or live in entirely virtual realities or simulated universes?
