A series looking at concepts for truly huge structures that we might see in the future. This is an audio-only compilation of videos created originally for Youtube, and is best watched rather than listened to, the video playlist can be found at:

MS10 Matrioshka Brains

MS09 Nicoll - Dyson Beams

MS04 Rotating Habitats

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 the Fermi Paradox, also known as the Great Silence, the seeming impossibility of having a Universe so vast and ancient that apparently has no other intelligent life in it but us.

FP01 - Fermi Paradox Compendium

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.

CS07 - Micro Black Holes And Hawking Radiation

CS06 - Interstellar Colonization

An in-depth survey of the various technologies for spaceship propulsion, both from those we can expect to see in a few years and those at the edge of theoretical science. We'll break them down to basics and familiarize ourselves with the concepts.
Note: I made a rather large math error about the Force per Power the EmDrive exerts at 32:10, initial tentative results for thrust are a good deal higher than I calculated compared to a flashlight

The Spaceship Propulsion Compendium

In this episode we continue our look at possible Alien Civilizations by attempting to peer into the alien psyche. In the absence of any actual ones to examine we will review fictional examples and try to match those up against both human behavior and what we might consider likely, unlikely, or impossible to arise from evolutionary processes.

Crazy Aliens

The first installment in a new series discussing alternative means of getting in space, from better rockets to massive structures like Space Elevators, Skyhooks, and Launch Loops.
