Legendary physicist Stephen Hawking seems to have answered a lot of unanswered questions regarding the evolution of life with his new book The Grand Design, in collaboration with fellow physicist Len Mlodinow. The physicists have tried to figure out the concept of life by absorbing previous theories of life and evolution to produce the best outcome possible.

The book has tried a different approach to the concept of life, which they have coined as model-dependent realism. The book states that there is no one complete truth and every being sees the world from their eyes and their mind. Further, every being tries to absorb each theory they come across and adopt the one which best suits them.

The book simply states that there is no one model, but in fact a lot of different ways in which one could predict the same situation; and if two different theories are able to forecast same events, none of them could be called wrong. Anyone who feels more convenient with a specific theory is free to use it and no one has the right to question their choice.

The book does not give an answer to any of the questions one might have regarding life, but just like Hawking, allows the reader to think about life and reality.

This book presents an open-ended theory and it would be up to the reader as to how they would apply the theory to themselves.
