Science & Futurism with Isaac Arthur

An overview of very large artificial constructs from space stations to Dyson spheres. Including building artificial worlds around black holes to how to destroy a star.

An in-depth look at the Fermi Paradox in terms of Kardashev 2+ civilizations.

A Comprehensive list of all the major proposed solutions to Fermi's Paradox, the question of "If there are aliens, where are they?"

A look at various Cataclysmic Scenarios in terms of how they factor into the Fermi Paradox. We'll look at everything from Biowarfare and AI to Nukes and Grey Goo.

First installment of a spin-off of the Fermi Paradox Series, focusing on how very un-Earth-like worlds might support life. This video focuses on how life might exist on worlds like Pluto.

This video covers what Tidal Locking is and what causes it, and looks at how this can happen to moons & exoplanets.

The second episode in the series examines Twilight Worlds, planets tidally locked to stars so that one side is always lit and the other side eternal dark. We discuss what life would be like on such a world and how realistic it is for life to arise there or for us colonize them.

This video takes an in depth look at Orbital Rings and Space Elevators and is the first installment of a reboot of the original Megastructures video.

The second installment of the series looks at the Skyhook, a type of abridged Space Elevator that allows spacecraft to hook up and get into orbit at much lower launch speeds.

In this episode we look at moons the size of Earth, what they'd be like, and the possibility of life evolving or colonizing such a world.

Episode 3 is our final look at Megastructures designed to help carry cargo and people into space at far lower prices than we currently pay. Main focus is on the Lofstrom Launch Loop, StarTram Mass Driver designs, and the Space Fountain.

This video gives an overview of various terraforming concepts and hurdles from those using near-horizon technologies to very advanced and speculative tech.

A detailed look at how Nuclear Fusion could impact our economy and civilization, from agriculture and water shortages to space stations and interstellar travel.

The Habitable Planets series continues with a look at Rogue & Steppenwolf planets in the Interstellar Void. This video considers both the possibility of life arising on such planets and the prospects for colonizing them.

In this fourth installment of the series we take a lengthy look at Rotating Habitats, large space stations that simulate gravity via spin and can replicate Earth-like environments.

Today we look at the subject of Interstellar Colonization, from the ship concepts and propulsion methods all the way to intergalactic colonization.
