Carlo Rovelli (born 1956) is an Italian theoretical physicist and author. He is one of the founders of loop quantum gravity, a leading approach to unifying quantum mechanics and general relativity, and his research explores the nature of space, time, and gravity. A professor at Aix-Marseille University, he has also held research appointments at leading institutions around the world. Rovelli is widely admired for making complex ideas in modern physics accessible to general readers. His bestselling book *The Order of Time* reexamines the concept of time through the lens of contemporary physics, combining scientific insight with philosophical reflection.
