Astrobiologist: Why time travel can’t really work

Recently, cosmologist Carlo Rovelli, author of The Order of Time, argued that time travel, especially into the future, can work. However, astrobiologist Caleb A. Scarf sees an insurmountable barrier, which he calls the “spatial problem”: Let’s take the Earth’s motion around the Sun. A month of orbit corresponds to moving in an arc of approximately Read More…
