The galaxy is a vast place with billions of potential new worlds for humanity to colonize, but interstellar space is so enormous that reaching even the nearest stars and planets by spaceship would take decades at best, and maybe many centuries. Even on arrival terraforming those barren planets would take just as long.

Two options for overcoming the immensity of space and time are the Seed Ship and the Data Ship, automated vessels able to colonize the worlds for us. We will examine those today, their advantages, limitations, and misconceptions, and variations of them we might use to seed the stars.

Today we're teaming up with Joe Scott to look at the Great Attractor, a mysterious and massive source of gravity obscured from our vision, and the concept of Dark Flow, movements of whole clusters of galaxies in directions with no obvious cause.

We often discuss the notion of settling the galaxy but do we need to stop there? This episode will examine the additional difficulties with traveling between galaxies and ask just how far we might be able to journey even without faster than light travel.

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.

In order to terraform new planets, we will need to be able transport entire ecologies & ecosystems through interstellar space in the future. Today we will examine how we could build and maintain such environments inside vast arks, generations ships able to colonize our galaxy, and the challenges these starships will face maintaining not just stores of DNA and genetic material but living organisms which depend heavily on other members of their species and other species to survive and thrive, not least of which is human ourselves.

Today we will begin our look at the spaceships we might use for colonizing interstellar space in the future. In order to cover the vast distances between even the nearest stars in our galaxy within the boundaries of known physics, we need vessels able to voyage at high speeds for very long periods of time while carrying everything they need to colonize another solar system, a concept typically known as a space ark or generation ship. We will explore the challenges and options for such a vessel, as well as some alternative approaches to the problem.

A look at the possibility of future civilizations rising and falling.
Visit our sponsor: https://skl.sh/isaac
It's long been observed that empires tend to rise and fall in a seeming cycle, never identical but sharing many similarities. Today we will examine the idea that this may be the reason that we have encountered no advanced civilizations in our own galaxy, and that the solution the Fermi Paradox, as to why we have seen no alien civilizations, may be that they are caught in a perpetual loop. Unable or unwilling to use technology which might allow them to travel the cosmos. We will also consider if such a loop may await us, or that we are already in it.
