In the second book of Planetary, more intriguing physics topics were brought to the table. From aliens to quantum physics, many plausible physics topics were touched on. The first topic I want to cover from the second edition of the Planetary was the experiments on the humans. The experiments done on those humans remind me of a more futuristic version of what the nazis did back when hey were in control. The idea of aliens and monsters being involved in the comic was another sci-fi like idea being incorporated into the Planetary. Along with many of the other ideas in this comic series, I find both of the idea of aliens and monster creatures to be have a slim chance of becoming reality.
