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

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

Industrializing the Moon

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

Today we discuss the concept of trade throughout a colonized solar system, and ask how viable it is and what challenged it faces.

While Interplanetary trade faces many challenges, Interstellar Trade faces even more, this episode will seek to examine in detail what can be traded between worlds, what probably can't, and what technologies might impact that.

Interplanetary Trade

Space is an incredibly harsh and immense environment absent of everything we need to live, and abundant only in harsh radiation and dangerous micro-meteors. Today we will examine how those will impact humans who come to dwell on space ships or habitats.

Surviving In The Expanse Of Space

Today we take a trip inward, to explore Sun-Scorched Mercury.

Mercury is the nearest planet to the Sun, a seeming airless wasteland little discussed in conversations about colonizing our solar system. Today we will challenge that, and show that Mercury may be one of the most promising places for humanity to make new homes on.

Colonizing Mercury

A continued look at Generation Ships and Interstellar Colonization.
Check out Cheddar's video on the Sun: https://chdr.tv/youtue6886
In order to colonize the galaxy, we are going to have to spend huge times on board equally huge spaceships. To move thousands of people, and our ecosystem, to distant planets, will require not only giant ark-like starships, but entire fleets of them. Today we will examine how we could do this even if physics never offers us any superior methods in the future for covering the void of interstellar space faster.

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

There's many dangerous places on Earth, and everywhere off Earth is downright lethal, from the emptiness of space to the airless and radiation soaked Moon to the smoldering inferno of Venus, humanity can't visit them without protection. We'll see what options for spacesuits are under works and what options might emerge for even better ones in the distant future.

Spacesuits

Venus is a desolate scorching world on which no life can exist. Yet if it can be cooled down, there is no other planet we know of more suitable for terraforming and colonization. We will examine methods of cooling Venus down and preparing it to be settled in the future.
