You never knew theoretical physics could be so simple! Why do things move? Is gravity a fundamental force? Why is the expansion of the universe accelerating? Can quantum mechanics and general relativity be realized as a fully consistent theory? What is wrong with the uncertainty principle? Is spacetime fundamentally continuous or discrete? Is the universe a black hole? How can the laws of physics be derived from one principle? Why does the Eddington value for the deflection of light differ from the Freundlich value in general relativity? What is the origin of mass? Does nature have more than four space-time dimensions? What is the lifetime of a proton? Why the proton radius puzzle so dangerous? Do we have a theory of everything? Is gravity and the laws of physics emergent? Is entropic gravity flawed? Is dark matter responsible for differences in observed and theoretical speed of stars revolving around the centre of galaxies, or it is something else? Why does the zero-point energy of the vacuum not cause a large cosmological constant? What cancels it out? This exciting book considers some of the deepest and most important questions in physics. Enjoy a thrilling intergalactic tour as Balungi Francis redefines the force of gravity and introduces a brave new view of the universe! A percentage of all royalties will go to charity.
