”Just in case anyone missed it.”
No MAX, I tried to avoid it but I did not miss it.
”Moving faster through space, makes you move slower through time.”
Who makes me move slower?
”Light has no mass.”
Light causes motion so it must have mass. Einstein won the Nobel for the photoelectric effect. Are you saying Einstein was wrong?
”Light propagates through space at a rate corresponding to time.”
As do all objects in motion, what is your point?
”Light experiences time optimally, time does not pass for a beam of light, it is merely a direction in space.”
What is “merely a direction in space” Light or Time?
”A time in the past corresponds exactly to a point in space for a beam of light. The same can be said for any other point in time.”
Or, any other point in space!
”Mass is an extremely energetic form of light.”
You just said Light had no mass, now you are saying mass is Light!
”Mass is so energetic, one could describe it as being tangled up in the fabric of space.”
What we need then, is a cosmic fabric dryer sheet!
”An object with Mass cannot move optimally through time, it could be thought of suffering drag from space.“
Suffer unto the masses, so sayeth the MAX!
”In order to overcome this drag, something has to be given up. Interaction with time must be sacrificed to overcome it.”
Should we slow down or speed up?
”Moving through space reduces motion through time.”
You are repeating yourself.
”Accelerating through space, reduces motion through time.”
You are repeating yourself, again!
”A gravitational field can be described as an accelerating frame, and it reduces motion through time.“
You are repeating yourself, again, again.
”If you have any questions you would like clarified about this, please feel free to ask.”
No questions from me MAX. Do you have any questions for me?

”Moving faster through space, makes you move slower through time.”
Who makes me move slower?
That was a question from you.
The ability to stop moving is what makes you move slower.
("That doesn't make any sense Max.")
Light has no rest mass, only relativistic mass. Light is an expression of motion, a photon can only stop moving by transmitting it's energy to another particle.
Bodies with rest mass can stop moving, the trade off of gaining rest mass is reducing your motion through time.
("Why do you keep saying motion through time, I'm sitting still, I'm not moving through time.")
You know the now you just saw? The one after that?
The now when you read this?
This one?
So on, so forth.
That is your motion through time, time doesn't pass any more than left or up passes.
You move through the left direction, you move through the up direction, you move through the downstream direction towards the future from the past, which is the upstream direction.
As you move through space, imagine that you're in a boat floating downstream in a river.
If you want to change your position in the river, you have to reduce your motion downstream.
It's as simple as that.

The clock is a boat.
Time is the river the boat moves through.
If the boat moves with the river, it moves downstream at a steady rate.
That is the "normal" rate of time for a body at rest.
If the boat begins to move across the river, it moves downstream at a reduced rate.
That is the "subjective" rate of time for a body in motion, a visual representation of time dilation due to acceleration.
If the boat were larger, it would move downstream at a reduced rate.
That is the "subjective" rate of time for a body with strong gravity, a visual representation of time dilation due to increased mass.
Max™, Beg to differ:

Max™ said: "If the boat begins to move across the river, it moves downstream at a reduced rate."
No, Max, the "boat clock" still moves down the river at the same rate. It just hits the other shore further downstream than a "boat" on still water.
Better drink some more of that water. . .might clear things up for you.

The river is always moving.
Better drink some water yourself, you still need to understand the nature of it.

Here is a little lesson in hydrodynamics for you: http://www.answers.com/topic/hydrodynamics. Rivers do all sorts of strange things. You just never sat down and watched.
A bigger boat may or may not: "If the boat were larger, it would move downstream at a reduced rate."
It depends on the depth of the river and the draft of the boat. In most cases a bigger boat would move downstream at the same rate as a smaller boat.
If they were sail boats, they could actually move up stream. Your analogy is bogus.
Re: Relativity explained in simple terms.
October 9 2008, 3:57 PM
You're picking apart the analogy for ridiculous reasons rather than attempting to see the relationship describing motion through time as floating down a river, and motion through space as moving against the flow of the river.
Sorry, Max™, that I'm so picky.
October 10 2008, 12:10 AM
It's just that you said "the boat (clock) begins to move across the river." I didn't realize that when you said "across" you meant "upstream."
Still doesn't make any sense to me.

The path on the right would be the one which was moving across the "flow" of time.
It still moves downstream, but if the lines were proportional and not distorted by the horrible ascii I just made, the boat on the right would have differentiated it's distance moved downstream from the one that wasn't moving through space (across the "flow" of time).

Ok, assume the top sequence of _ signs and the bottom / are the same size, just rotated by their motion.
The top 5 move through time further, the bottom 5 move through space further.

Hey, look, Max did it. Simple terms!!
