Was Einstein wrong? Has physics taken the wrong detour? Why quantum world is so mind-boggling? What are Dark Energy and Dark Matter, and why do we need them? Imagine all key questions in Physics answered! A world where Big Bang, Dark Energy, Dark Matter, Gravity, Multi-Universe, Quantum Superposition, and Time Travel are no longer an enigma. While taking you along a journey through the alleys of history, this book conducts An Audacious Review of the theories of physics to address these questions, while keeping the discussion simple and lively, and attempts to connect the theory of very big (Universe) with the theory of very small (Quantum) towards a new Theory of Everything. It does so while staying within the framework of Scientific Methods.
