This is probably a repeat question from somone somewhere, but here goes. Please fill in the blanks. I don't need a full explanation, because as much as I tried, I probably wouldn't understand it anyway: Ann and Bob live on Earth. Bob is bored and decides to take a journey to a space station that is 1 light year away, as measured from his stationary location on earth. Ann stays home. Bob travels at very near lightspeed (say 0.99999c) to his destination 1 light year away. He departs on January 1, 2010, at noon. Bob arrives at the space station, and immediatley calls Ann with a signal that travels at lightspeed. "Hi, Ann, this is Bob. My calendar watch says that it is _______________(please fill in month, day, time.year). What's is your date, year and time as you receive this message?". Ann ultimately gets the message, and immediately responds "Hi, Bob, today is ____________ please fill in month, day, time,year). Thanks for calling." Just fill in the blanks. I'm trying to se if time dilation is still in effect, even though Bob never physically returns to earth to physically compare that he has aged less than she. I'm guessing that the fill in for the first blank (Bob's call) is about January 2, 2010, and Ann's response (the fill in for the second blank) is January 2, 2012. More or less. Good guess, or wayyyyy off? Thanks.
