Light Years Away

The basic questions that we encounter like, where is the end (boundary) of the universe, what can be the nature of the extra universal things, is light the fastest; why we are unable to explain the universe etc have been addressed in a scientific and logical but unsophisticated way.

Of course some back ground in the subjects like physics and astronomy can help in the better understanding into the matter. But for any enthusiast of space and cosmos irrespective of the back ground and age "Light Years Away" will be a satisfactory text.
