It's once again Friday so it's time to strap yourselves in for our weekly neatorama review. Probably my favorite this week was the article on advanced civilizations. Here's a bit longer quote then i normally give to pique your interests.

Michio Kaku, professor of theoretical physics at the City University of New York, wrote a fascinating article in COSMOS magazine comparing our current state of knowledge and "level" of civilization with what is possible in the universe.

In a seminal paper published in 1964 in the Journal of Soviet Astronomy, Russian astrophysicist Nicolai Kardashev theorised that advanced civilisations must thus be grouped according to three Types: I, II and III, signifying mastery of, respectively, planetary, stellar and galactic forms of energy usage. He calculated that the energy consumption of these three types of civilisations would be separated by a factor of about 10 billion.

Where are we right now? Not even type I (according to Carl Sagan, we’re at 0.7!), but we’re getting getting there! There are already evidence everywhere of an emerging Type I civilization.

It’s a fascinating read: in the article, Michio speculates about von Neumann probes visiting Earth, the perils of encountering Type III civilization, harnessing the energy equivalent to that of a blackhole, and more!
