While reading How to Live Safely in a Science Fictional Universe, I found myself repeatedly thinking about time travel because it is the principal theme in Yu’s book. In class when we were discussing the validity of time travel, someone in class mentioned that technically we are all time traveling. Time is progressing forward and we are moving with it. Whether this is considered time traveling or not depends on how you define time travel. Yu defines time travel as “any journey in which the interval of time experienced by the traveler is not equal to the interval of time measurable by those not traveling with them” (215). According to Yu, we aren’t time traveling. Do you agree with Yu’s definition of time travel or do you think we are all technically time travel by living life?
Another idea that I found really interesting was the concept that two timelines run simultaneously when you time travel. This is based on the assumption that time travel itself requires time. Yu is in his time machine for about 10 years, but in real time only a week has passed. I had never thought about this because I had always assumed time traveling would be instant.
I don’t know much about time traveling, so I was wondering what other people thought about the logistics of time travel that Yu brought up in his book or about time travel in general, such as the physics of it.
