Ecumenopolises

In our second look at possible futures for Earth we examine the concept of Ecumenopolises, planet spanning cities homes to trillions. We’ll examine concept in detail, starting with the first portrayals of it in fiction and extending on how Arcologies and other technologies we’ve discussed on the channel might be employed to create a Ecumenopolis and what they might be like to live in.

Arcologies

In our first look at possible futures for Earth we examine the concept of Arcologies, self-sufficient habitats that adapt the concepts we’ve previously considered for space stations and off-world colonies to Earth itself. We’ll examine the original concept, the more modern one of giant structures that dwarf skyscrapers, and under what circumstances such ideas can be practical.

Megastructures 09 Nicoll Dyson Beams

Continuing our look at Dyson Spheres we examine the concept of the Nicoll-Dyson Beam, a type of advanced weapon that uses the output of an entire sun to create a laser that can strike target across the galaxy.

The Doomsday Argument

A look at the Doomsday Argument, also known as the Carter Catastrophe, a probabilistic argument which suggests humanity may be nearing its end. We will examine how this applies to the Fermi Paradox and the Simulation Hypothesis, as well as examining the concept of the Anthropic Principle.
