description: In 1900 the British physicist Lord Kelvin declared There is nothing new to discover in physics. All that remains is to more accurately measure its quantities today hardly anyone would dare say that our knowledge of the universe and everything in it is almost complete.There are still some deficiencies in the standard model of physics such as the origin of mass the strong CP problem neutrino oscillations matter-antimatter asymmetry and the nature of dark matter and dark energy. Another problem lies within the mathematical framework of the standard model itself.Some of the major problems in physics are theoretical meaning that existing theories seem incapable of explaining a certain observed phenomena or experimental result. The others are experimental meaning that there is difficulty in creating an experiment to test a proposed theory.In this book  there is given a discussion of what are arguably the most unsolved problems in physics astrophysics and cosmology. And this book sets to solve them living none untouched. The form of the discussion is not negative: formulating a problem succinctly is essential to a solution. Perhaps the most remarkable aspect of the book is that many of the problems are interrelated so the solution of one or a few opens the prospect of widespread advancement. The book is optimal for researchers students and teachers pursuing a career in physics astrophysics astronomy and cosmology.
