The possible levels of information mastery in the future of technology.

This series focus will be on the Information Mastery version of the Kardashev scale. In his book, The Cosmic Connection, Carl Segan proposed an alternative approach to the Kardashev Scale. He added another dimension to the original scale in addition to the pure energy usage that was first used to characterize different civilizations. Sagan believed that the amount of information available to a civilization should be an important criterion when trying to come up with a useful metric to measure different types of civilizations. So he assigned a lettered scale from A-Z where each letter meant an order of magnitude increase in the volume of information a civilization can hold. This information, he proposed, could be described in terms of bits, the number of yes or no statements concerning different civilizations, and the universe that such civilizations occupy.

The gargantuan artificial construct enveloping your local star is going to be rather difficult to miss, even from a few light years away. And given the literally astronomical costs of resources needed to construct such a device — the still-theoretical-for-humans Dyson Sphere — having one in your solar system will also serve as a stark warning of your technological capacity to ETs that comes sniffing around.

Or at least that’s how 20th century astronomers like Nikolai Kardashev and Carl Sagan envisioned our potential Sol-spanning distant future going. Turns out, a whole lot of how we predict intelligences from outside our planet will behave is heavily influenced by humanity’s own cultural and historical biases. In The Possibility of Life, science journalist Jaime Green examines humanity’s intriguing history of looking to the stars and finding ourselves reflected in them.
