would be the younger. For this discussion, I challenge you to consider a modified scenario: the two twins of equal age part ways, but this time they both rocket away with equal speeds but in opposite directions (let's call them north and south), leaving Earth behind. After a previously agreed amount of time, both twins turn around and return to Earth, arriving back home simultaneously. Think about this scenario, then share your thoughts on the following prompts by Sunday night: 1. Will the twins share the same age upon their return? If not, which will be the younger? 2. Will either or both of the twins have aged differently than the Earth-bound friends they left behind? If so, will the twin(s) be younger or older? 3. Justify each of your answers in a sentence or two. Up to 2 points of EXTRA CREDIT will be given for any thoughtful, respectful, and constructive response to a classmate, up to a maximum of 4 points. You'll have an extra week past the due date to post responses
