depending on your frame of reference, correct? If I am standing still, and at the same time (my time) shine 2 flashlights in opposite directions, after one second on my watch, the leading edge of the light beams will be 372,000 miles away from each other. (186k miles to my left, and 186k miles to my right) Or, if I look up in the sky and see two space ships pass each other going in opposite directions, after 1 second on my watch, they will be 372 thousand miles apart. (2c) However, on each space ship, no time has passed at all. Anyone on board would think they were in both places at the same time. Nor could anyone on board measure how fast they were going, or how fast the other ship was moving, because no time has passed for them. No one on board could even take a breath, or move to control the ship, because no time is passing, and any movement would take time. If you could look in the window of a space ship full of people going at light speed from earth, even if you looked at them for 1000 years of earths time, everyone inside would appear frozen. No one could move or do anything because no time is passing for them. So if you slow them down a little bit so that one year passes for them while 1000 years pass on earth, they could still only accomplish in one year what we did in 1000 years. Nothing is gained for them. They do not live longer in "actuality" than someone on earth, its just that time has slowed way down for them. Actuality I would mean by the amount of time they would live in their "local" time. Please let me know if I have this right. I think I do, and if so, its not that hard to understand. You just have to shift your thinking to understand time is not constant, and this would be "common sense" if you were born and raised in a time when traveling at all different speeds up to near the speed of light were possible. You would see and experience it happening every day, so it would be perfectly normal. Its only "strange" because we can not experience it yet in our everyday life.
