The fear of asteroids

The book
Asteroids and end of the world 

analyzes the possibility of the world ending by a collision with an asteroid.

The fear of end of the world by asteroid collision is an occupational hazard not just for the informed but also for the uniformed, as ways of deflecting the space objects away are being contemplated. 

It is assumed that a big asteroid hitting the earth, if not fragment it up, is capable of inducing wide spread extinction of life species including humans.

A space monster drifting in our direction is a sure cause for alarm. Any astronomer Manning the telescopes will always do the obvious; blow the whistle, the end of the world has come. 

This is the anatomy of doomsday. 

Why none of them materialize is not the fault of the whistle blower. He got his calculations right. A trajectory intersecting with that of the earth at a specific point leaves no doubt of imminent redezvous. 

But, despite, all doomsday dates pass as normal days except for gloomy weather in isolated cases.

Besides prayer doing the trick by divine intervention, a certain principle of gravitational dynamics always saves the day in the scientific point, sparing mankind of one of his biggest occupational dread, the end of the world.

This book, Asteroids and end of the world explains how   gravitational principles work and where they intervene to save the earth from asteroids' collisions.
