Gravity does not exist

"What we know always leads to what we do not know. This book follows the historical path of the most brilliant theories in physics, and the people who made them: the general theory of relativity and quantum field theory. The paths of these very successful descriptions of the Universe intersect. When the two theories collide, the light that they shed on the understanding of our world is extinguished. We do not know the road ahead. Can they be merged into a single theory? Nobody has an answer yet. Where are the clues? In theory, experiments, mathematics, or cosmology? Is the most important physics question of our time too difficult, or is the answer already growing in the mind of a young woman or man somewhere in the world?"--Book jacket.
