Physics, Monday, Class #10, Period 4
"Afternoon, everyone," Sam greeted the students as they entered, "and please consider this your official reminder that the end of the semester is coming up, and I'll be expecting to see your pumpkin chuckers and to hear about the theory and math behind your design, unless you'd prefer not to have to defend it out loud and choose to write a paper and show me your work that way instead."
"Today, we're going to be discussing time travel. Which, considering a good number of you are from the future, may seem a bit unnecessary. As I've been reminded, however, even if you're looking at this area of physics in an 'isn't that cute,' historical way--which, by the way, I appreciate you keeping that particular sentiment to yourself--it still gives you a point of reference for why it takes the human race so long to get there."
"One of the biggest problems with time travel, of course, is the creation of paradoxes, particularly the ever popular grandfather paradox. But is it really a problem? Several physicists have theorized that time travel through a wormhole," and here she may have smiled a little, "won't lead to a paradox. Another way around the paradox is the discovery that you're not actually traveling within your own universe, but are instead within a parallel timeline, meaning that you're having an effect on someone else's universe, not your own."
"However, if you're ever in an alternate universe with another version of yourself, I can tell you now that entropic cascade failure is a very painful reality. Obviously Fandom is the exception to this rule, as it is to so many others. Anyway, I digress. Stephen Hawking has a theory that the fact that we haven't seen tourists from the future means that Fermi's paradox exists and that time travel hasn't been discovered. However, isn't it just as likely that it's used cautiously? I'd like you to discuss the implications of time travel with each other. Also, would you travel in time, if you could? Why or why not? Do you honestly think it's possible?"
