Extraterrestrial Life

Description:

In this 63-page book the author answers in a brief and clear way questions such as “What fantasies did extraterrestrial life provoke in our ancestors? What is the opinion of the modern man on this theme? Have the ideas changed with time? What is the real possibility that life exists elsewhere? What do scientists think about the topic?”. The author also talks about the nearest stars and gives the reader a better understanding of distances outside of the earth by making a scale model of our solar system in which the sun is just a pea, Pluto is a microscopic particle 40 meters away from the sun-pea, and the nearest star (another pea) is 270 km away from the sun-pea.
