Fermi Paradox: The Prime Directive 15.11.2020

One solution to the Fermi Paradox, the big question of where all the aliens are, is that extraterrestrials might hide from us to avoid altering our society, a concept we see in Star Trek called the Prime Directive. Is such a policy ethical, and if so, should we follow it? Watch the Video Version: https://youtu.be/TwNdj76CK-E Visit our sponsor, Brilliant: https://brilliant.org/IsaacArthur/ Visit ou...

Becoming a Kardashev- 1 Post-Scarcity Civilization (Narration Only) 05.11.2020

The Kardashev Scale measures how powerful a high-tech civilization is, with K-1 indicating a advanced society able to call on all the power of their planet, which we often envision as a Post-Scarcity Utopia.

Terrifying Aliens 29.10.2020

Mars Base (Narration Only) 22.10.2020

To become an Interplanetary Species we need to colonize another planet, and Mars will be our first target. To establish a base there, and a future settlement, we need to get their first, so we will also examine the Aldrin Cycler, a type of spacecraft that may make traveling to other worlds far easier.

Low-Tech Spacefaring Civilizations (Narration Only) 15.10.2020

We typically imagine interstellar civilizations as vastly superior in technology to modern times, but could the future see planets colonized by spaceships little better than our modern ones? Could some alien worlds allow space travel to develop far sooner and easier than it did on Earth? Or could civilizations abandon more advanced technology?

Response And Analysis Of Recent UFO Disclosures From The US Military 11.10.2020

Recently the Military released Navy footage of 3 separate UFO or UAP - unidentified aerial phenomena - we will review that footage and consider both mundane explanations and the not-so-mundane, like secret projects, extraterrestrial origins, and what it might indicate about the technology and motivations of such alien civilizations if they are visitors from out in the galaxy.

Return To The Moon (Narration Only) 01.10.2020

It's been over half a century since we first went to the Moon, and nearly as long since we last went.
