Just finished reading A Brief History of Time by Stephen Hawking and I have a newfound fascination with time. One of the concepts he discusses is the relativity of time and gravity’s effect on it. As in, time moves slower near large masses due to their gravitational forces. Taken to the extreme, if I were to travel close to a black hole, time would slow down significantly and seconds for me would be hours on Earth for instance (just making up the scale but like in the movie, Interstellar).
It makes sense theoretically, but when I try to think about it practically, I’m having a hard time fathoming it. Would this potentially be a way to “time travel”? As in, travel to a distant planet 10x the mass of Earth, live there a year and return to Earth for it to be 10 years in the future (assuming linear scaling and a host of other assumptions of course). Thoughts? Any recommendations for other books on the topic? (just ordered The Order of Time)
Hey Hamilton, have a holly jolly Christmas.
