7. The point you're making is based on a misunderstanding of relativity.
Edited on Tue Dec-21-10 01:07 AM by laconicsax
Each would see the other ship as the one 'moving fast' so why would one of them move slower in time then the other, unless there is some absolute 0 speed.
Because the rate at which time passes is proportional to speed. You don't need some absolute 0 speed to see that someone's clock is running slower or faster.

tell me how do you know who is moving faster between the two objects.
If two objects are in space, and one is moving faster, you can determine which is moving faster by using time dilation--the faster ship will record a slower passage of time.

You need a point of reference, how do you not know if the earth flew by the rocket ship and the rocket ship was stationary.
There are no privileged reference points; it's all relative. To an observer in the rocket ship, the Earth did fly by the ship, which remained stationary. Think about that the next time you're in a moving car.

the story of the clocks on the ship to the moon has holes in it.
Sorry, it doesn't. Less time elapsed for the Apollo astronauts during their mission than for the mission controllers on Earth.

I actually think I understand it, however it could be actually acceleration, where space time also moves, and only applications of force could cause dilation, but that still would break some of those concepts.
Acceleration does play a factor, that is, the acceleration due to gravity. Time passes 4x10-16 faster for an object at one foot above sea level than for an object at sea level because of how gravity warps space-time.

Try this site. I haven't spent much time there, but it looks like it might be a good primer on relativity.
