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

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

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 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

Continuing our look at possible alien civilizations, we examine extinct alien civilizations and the possibly of finding them and exploring their ruins to learn about them. We will also contemplate the possibility of bringing them back, and the conundrums that raises.

Dead Aliens

Black Holes are amongst the most destructive things in the Universe, but it may be that properly utilized, they might be the best places in the galaxy to live around in the future, and possibly right here in our own solar system too.

Colonizing Black Holes

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?
