no, you and your watch have aged slower.
hmmm, I`m begining to feel unsure here...
perhaps you´re right
I´ll have to think about that
Ok, if I have aged 10 min while going at near light speed.
how much have the other people aged?
If I am on earth, I look at the spaceship or whatever.
It goes very fast. I can see it going back an forth between point A and point B for 10 min then the ship stops.
The person in the ship has a stopwatch. He starts it when he launches and stops when he stops.
Will it show 10min? What will it show? more or less
Look at it this way. Your traveling at .5 the speed of light away from a stationary human in a completely dark surrounding. The only thing is you and your companion. As your going away he is waving. He looks to be moving at half the normal speed. So it would seemyour time traveling. Now to him, the stationary object, It looks like he is the one moving away at half the speed of light from you. ( since there are no other objects besides you two, neither can truly say who is moving. B/c there is no other object to prove who is motionless or moving.). So each of you think that your moving away at .5 the speed of light. And the other person looks like he is moving half as fast. (this is b/c of the delayed time it takes for light to reach you b/c your moving so fast.) So both of you think your time travelers when only one is.
Six of one, a half dozen of the other. Both are technically correct.
And therefore the rate at which time passes for you. Perception of time and time itself are the same thing.
It's been proven experimentally that time passes more slowly at higher altitudes, where light is less affected by Earth's gravity. If you want a chance to live longer than your friends, move to the top of Mt. Everest.
You might manage to accumulate a whole second over your entire life!
If you are watching from outside the ship for 10 minutes, your stopwatch will show 10 minutes and you will be 10 minutes older. For a traveller inside the ship at near light speed, significantly less time will have passed, probably only a few seconds. There is an equation to figure it out, I don't remember it off the top of my head. Search for "time dilation" on the internet.
Of course, the G-forces exerted on his body at near light speed would reduce him to a messy red blotch, so you would be better off.
and thus you have travelled in time
i keep this handy for just such an occasion. He gets to the time travel around the end, think of the rest as a big introduction.
Yes, in a relativistic sense.
Is "relativistic" a word?
Separate names with a comma.
