Albert Einstein's theory of general relativity suggests backward time travel is possible in some scenarios, but do those situations ever exist in our universe?

Andrew Jaffe probes Carlo Rovelli’s study arguing that physics deconstructs our sense of time.

According to Albert Einstein’s general theory of relativity, gravity is no longer a force that acts on massive bodies, as viewed by Isaac Newton’s universal gravitation. Instead, general relativity links gravity to the geometry of spacetime itself, and particularly to its curvature. Learn more at the link!
