A Brief History of Time is the original copy of the Kaler Sangkhipto Itihas book written by British physicist Stephen Hawking. In this book, Stephen Hawking explained the Big Bang theory and Black Holes. This book is a popular-science fiction book about cosmology (the study of the universe).
This book was written especially for nonspecialist readers who have no broad knowledge of scientific theories. This book is so helpful for them who are interested in science.
