time dilation???

Also maybe to bring it back to the topic of time. It would also make sense that this infinite God would be able to control time, so maybe once he's freed what is of him from the physical he would then reverse time back to before the big bang and force time and space and whatever else isn't of God into an infinite singularity.

And maybe whatever is of God would be able to see all this happen from a non-physical/spiritual perspective.

Okay, maybe this isn't on topic, but still interesting to think about.

That's the really cool thing about astronomy. It offers us some very interesting things to ponder and consider, including the nature of singularities, multiverse theories, string theories, and all sorts of other weird possibilities.

Moving objects look shorter, not longer.

That will teach me to try and remember physics classes from a decade ago without refreshing my self on it

Here is a good one to think about, according to the theory of special relativity, time slows down, at high velocities.
Ok, using only theoretical apparatus such as a chain and sprocket drive, with a chain that has the miraculous ability to stretch infinitly to maintain a constant sprocket teeth to chain relationship, such that a motor connected to one sprocket is stationary on the earth, and on the other end of this miraculous chain is a identical sprocket connected to a shaft fixed onto the body of a rocket ship.
Also both sprockets have a light beam interuptor, that allows counting of revolutions, per minute to be displayed on board the ship and another one on the earth.
Now lets say the rocket is at a stand still, and the motor is turned on, and is now spinning at 60 rpm's, the light beam interuptor shows a tach reading of 60rpm's on both the ships tachometer, and the earthbound tachohmeter.
Now an inspection is made and seen that this miraculous lengthening chain, is keeping track with the sprocket drive, as would normally be in a mechanical system containing a sprocket chain drive.
according to the laws of physics, the driven sprocket is keeping track with the driving sprocket due to the chain links connection between them.
So far it all fits in to mechanical laws.
Now lets suppose the rocket takes off and is approaching the speed of light, this miraculous lengthening chain is stretching so as to keep all the links in synchronization with both sprockets.
Now the motor on the earth is turned on and is given to rotate for 3 minutes, so the motor is rotating its earthboun sprocket 60 rpms, for a total of 3 (earth minutes), the tachometer reads exactly 60 rpm's, and the interuptor shows 180 rotations on its display and immediately the hypothectical motor is able to shut down.
The earthbound display shows 180 revolutions in 3 earth minutes of time, how many revolutions would the display show on the rocket ship, in other words the earthbound sprocket revolved 180 times in 3 earth minutes, but what would be the total amount of revolutions the sprocket onboard the high speed rocket show???

That experiment has been done with atomic clocks.
The "Linked chain" is the constant of the clock system.
The clock in the jet plane came back with it's reading slowed.

Ok, so now that I can sit down and actually post from a computer, let me take a crack at it. We've got several parts:

1. Local gear: Stationary, but rotating, follows local time
2. ship gear: Moves at ship speed, relativistically slowed to ship time
3. Outgoing chain: Speed is a function of distance. Locally, we can call this chain speed. the ship side will be ship speed + chain speed.
4. Return chain: Speed is a function of distance. Locally, we can call this chain speed. the ship side will be ship speed - chain speed. At some point, the return chains speed will match the chain expansion rate, resulting in a link that is stationary in respect to the earth. Let's call that link 0

All links being fed through the local gear will ultimately be links created between link 0 and the earth gear. No links that pass the ship gear will ever reach earth.

This, with some work, would probably be a pretty good analogy for expansion actually.

SFS, how's this look?

I'm on vacation. I've got cows in the field to my left and a llama in the field to my right; spread out in front of me is the Juan de Fuca Strait in the setting sun. I am not pondering relativity thought experiments tonight. Maybe tomorrow. . .
