Not many people have the luxury to think about things that do not revolve around their own world which is a very concerned, little world. All of the humanity is busy in their own life, concerned and worried about the problems that relate to their circle of friends, family, job issues, health and financial concerns, etc. All our life, we hardly get the time to stop and think about the world around us, about the people who are not our friends or our immediate family and we almost never pay any heed to the mystical workings of the universe. Even if someone does has some spare time to spend on thinking about the universe that we live in and the galaxies that exist along with ours, we hardly concern ourselves with it and never dedicate ourselves to discovering more about what exists beyond our world.
A lot of us believe that it is only the job of scientists and explorers and philosophers to crack the cosmic code. Average people neither have the time nor the interest to take some time out of their busy schedules and family time to concentrate and explore how the heavenly bodies, the stars and the many many galaxies present in this universe work. However, many physicists have written a number of books, blogs and theories on how they think and believe the cosmic world works. People who are interested in the celestial field and the planetary world often use these books and readings to quench their thirst for celestial knowledge. These books have interesting theories that are factual and concentrate on the goal to crack the cosmic code. Taking some time out of your busy schedule to study about how our world came into being and how the universe is an amazing phenomenon, brings many things into prospective.
