The physicist and author investigates the 20th century scientific revolution that changed our lives—and how it can go further—in this provocative essay.Much of the modern world we experience day to day has been profoundly transformed by a scientific revolution that began in the early twentieth century. But what has science done for us lately? In This Changes Everything, author and scientist Colin Gillespie suggests that the revolution has barely gotten off the ground. In fact—it’s still stuck between two competing Theories of Everything. While celebrating the victories of General Relativity and Quantum Mechanics, Gillespie attempts to uncover what holds us back from reaching even greater accomplishments. Looking at the work of physicists from Albert Einstein to Stephen Hawking and beyond, Gillespie proposes a thought experiment that leads to some startling conclusions. His provocative new take on cosmology and physics offers an elegant insight that truly changes everything.
