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

In Episode 3 we look at the concept of warp drives, a theoretical type of spaceship propulsion that warps spacetime to allow faster than light travel. We discuss the basic concept and the scientific and technological hurdles to developing it, along with clearing up many of the myths about it.

FTL03 - Alcubierre Drive

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

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

We continue our look at hypothetical alien civilizations by discussing the various possible circumstances in which we might first contact them or be contacted by them.

First Contact

Natural disasters can topple civilizations, even in modern times, but with more and more technology civilizations become more robust and capable of predicting future calamities and preventing such ruin. So what other threats face spacefaring civilizations, both at the interplanetary and interstellar scale?

Threats to Interplanetary & Interstellar Civilizations

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?
