The Theory of Everything - The Origin and Fate of the Universe ~ Stephen Hawking

A great modern physicist and the author of the bestseller, A Brief History of Time is here again with his book The Theory of Everything; The Origin and Fate of the Universe. He also authored The Black Holes and Baby Universes.

His book takes readers into the depth of origin of the universe, Big Bang, String Theory and Black Holes. It covers a series of seven lectures on cosmology, delivered at universities and conferences. Despite the study of cosmology being complex which includes various equations, he tries to make it simple for the public. It also takes readers back into the theory of Aristotle’s determination of cosmology and Hubble’s discovery of cosmological particles and theories of various other ancient renowned physicists.

The book describes the history of cosmological discoveries beginning with Galileo’s invention of telescope until the modern day approach towards latest scientific researches on universe and black holes. He describes black holes based on his research which took him more than a decade. According to his research, space-time may be finite in extent but without boundary or edge. Also, black holes has boundary-like particles known as the event horizon. He exemplifies this by giving us a picture of the earth which has a boundary but no edge. You can travel around the earth and reach to the same point but you would not fall off the earth because it does not have an edge.

Hawking also takes us deeper in explaining his theories and arguments on expanding universe, black holes, origin of universe and direction of time. He explains the influence of gravitational forces and magnetic field on black holes and speed of light. His theory also explains that there might be many more dimensions in outer space including space and time. According to his theory, time travel might be possible. However, it might seem like a science fiction.

As a great scientist, he tends to make the public aware of cosmological studies by simplifying his theories. The book is a treat for anyone who is fascinated by the concepts of universe, outer space, space-time etc. If you ever wondered and gazed at the night sky with fascination, there is nothing like reading Hawking's books who is not only a great scientist but also a literary man.

A great scientist and an author Stephen Hawking of the phenomenal bestselling book, A Brief History of Time  has done it again with his book Black Holes and Baby Universes. The book with calligraphy and great scientific theory sheds  light on the unexplored regions of the black holes, light, space and time. I haven’t as yet read his masterpiece, A Brief History of Time though, since I have lost the book but somehow I will try managing it from the book store.

Despite being physically disabled, his adroit and phenomenal equations goes beyond the consistent limited black holes and universe exploration. He has taken the scientific world over limits and his book also takes the audience into the intricate details of black holes, time, space and the universes. The black hole theory has been ramified attributed to his numerous years of researches, according to Hawking, black holes are not black. He has also suggested that there might be numerous black holes in the universes considering the existence of numerous other unobserved or undiscovered universes.

Black holes absorb everything including light, his theory talks about radiations and particles which travels faster than light in the black holes which are emitted steadily. The speed of light is usually distracted in the black holes by the minute radiations, probably invisible. What happens to the radiations and particles emitted steadily from the black hole is unknown and therefore what happens eventually in the black hole is also unknown. However, he has described briefly the phenomenal theory and his researches about the black holes.

Stephen Hawking takes physics to a whole new level compared to other scientists about the origin and the history of the universe since the big bang in the real time but what exactly occurred before the big bang still remain a mystery. However, in the imaginary time if considered, it would reveal the dimensions of space and time or even the other unknown dimensions in cosmology. Imaginary time considers that the universe has neither beginning nor an end. The universe is self-contained and pre-determined.

The book describes the formation of black holes and existence of some advanced species in the other universes.

What I learned now is that the universe is expanding to the lower state of density and we are out of the black hole. Stephen is also fond of classical music besides his scientific studies.

Punakha Dzong, Bhutan

Punakha Dzong was established in 1637 and its the second oldest Dzong (Fortress) and the second largest Dzong in Bhutan.

The Royal wedding of His Majesty The King of Bhutan Jigme Khesar Namgyel Wangchuck and his Fiance' was held here.

Here are some of the random pictures of the Dzong:
