Space stretches and this is the cause of the light stretch.

What is your explanation?


Uniform stretch everywhere doesn't work.
This is why shells grow in spirals.

Take 3 towns,; A, B, and C.
B is 10 km north of A. C is 10 km
north of c.

Now double all the distances
in one unit time.

B is now 20 km north of A.
C is now 20 km north of B.

So what?

Well, B moved 10 klicks.
How far did C move? (Hint: B is now
where C used to be.)

Well, B moved 10 klicks. How far
did C move in equal time? What about
D, E, F.....all originally at 10 klick
intervals? Get the picture?

That's why the velocity of galaxies away from us is proportional to
their distance (until relativistic effects kick in, and their relative
velocity compared to us becomes ambiguous).

Which is fine if we are the center.
