What Do Alien Civilizations Look Like? The Kardashev Scale

TL;DR

Humanity contemplates the existence of alien civilizations and our place in the universe.

Transcript

An observable universe is a big place that's been around for more than 13 billion years. Up to two trillion galaxies made up of something like 20,000 billion billion stars surround our home galaxy. In the Milky Way alone, scientists assume there are some 40 billion earth-like planets in the habitable zone of their stars. When we look at these numbe... Read More
