"There are grounds for cautious optimism that we may now be near the end of the search for the ultimate laws of nature." Stephen Hawking "Nature uses only her longest threads to wave her patterns, so each small piece of her fabric reveals the organization of the entire tapestry." Richard Feynman The major Unsolved problem in Physics Our two foundational descriptions of nature, quantum mechanics and general relativity, are incompatible with each other. When this conflict is resolved, a different view of reality may emerge that unifies matter, space, and time. Cosmological observations are providing additional clues that our understanding of reality is in need of drastic modification. Only 4% of the Universe energy content is known 23% is in the form of some unknown dark matter 73% is in the form of an unknown dark energy that is accelerating the expansion of the universe The fundamental questions every physicist must answer: 1)What is the dark matter? 2)What is the nature of the dark energy? 3)How did the universe begin? 4)Did Einstein have the last word on gravity? 5)What are the masses of neutrinos and how have they shaped the evolution of the Universe? 6)Are protons unstable? 7)Are there new states of matter at exceedingly high density and temperature? 8)Are there additional space time dimensions? 9)How were the elements from iron to uranium made? 10)Is a new theory of matter and light needed at the highest energies? In pursuing our quest to solve the above given fundamental questions in physics this book will: 1)Fulfill the innate Human desire to understand our place in the universe 2)Build the foundations for tomorrow's breakthrough technologies 3)Unite Quantum mechanics with General relativity into a Quantum theory of gravity.
