In t=3, X is farther away from the ends of the graph than it is in
t=1, because space expands over time.
If we consider X to be light, then it moves at a constant speed.
v = d/t
If v is constant, d and t need to increase proportionately.
But, if v isn't constant, but actually decreases over a few hundred
million light years, then t can increase while d doesn't change at
all.
So if you can visualize X moving at a constant speed on a grid that
expands;
And then if you can visualize X moving on a constant grid, but
decelerating over it;
Then you should be able to determine that both graphs (constant_speed/
expanding_grid versus decelerating_speed/constant_grid) are
mathematically identical.
Here are three steps of an object traveling left to right over a grid,
and the object slows down:
|X.....| (step 1)
|..X...| (step 2)
|...X..| (step 3)
Now the same three steps, played while you're zooming-in during each
step (more space) then you can zoom-in on the grid to give the
illusion that its traveling at a constant speed
|X.....|
| . .X . . . |
|. . . X . . |
So expansion redshift is an optical illusion, light slowing down in
static space.
We're seeing the limits of special relativity's speed of light
postulate when we observe expansion.
This isn't a full model, of course, but it is different that Tired
Light models that have been examined in the past.
utter piffle
Speed of light is a constant, its been proven by numerous experiments.
Sorry unless you have some evidence that contradicts the experiments,
your wrong.
Cheers
