    Spacetime: Stretching or Growing? Or

    Interesting point. I think this effect was already observed and measured. Angular size redshift relation an object ... beyond a certain redshift (roughly z=1.5), appears larger on the sky http://en.wikipedia.org/wiki/Angular_diameter_distance#Angular_size_redshift_relation...

    Spacetime: Stretching or Growing? Or

    A larger atom is the same thing as observing it closer: all it's constituents will be (appear) larger, strings, quarks, orbitals, wavelength. It's just a matter of scale. (by larger atom here, I do not mean uranium vs hydrogen, I mean identical but larger). Just imagine a diagram of an atom...

    If matter contract, then atoms were bigger in the past, emitting bigger wavelength light, and so appears red-shifted when we receive it. The further away a galaxy, the bigger it was when the longer ago its light was emitted, the more redshifted it appears to us.

    Time and distance relative to an expanding universe

    From wikipedia: the observable universe consists of the galaxies and other matter that humans can in principle observe from Earth in the present day, because light from those objects has had time to reach us since the beginning of the cosmological expansion...

    I agree with you. This image doesn't show or prove "Matter Contraction". My point is just that "matter contraction" has exactly the same observational effects as "space expansion": redshifted galaxies, the more redshifted the further away they are. Of course, if both descriptions are...

    Why does light and gravity travel at the same speed?

    The photon are massless, so (it is believe) are the gravitons (which have never been observed). So they both travel at the speed of light.

    I basically agree with your comment. Thanks for the reference, it is very interesting. It deals directly with the many issues I have trying to understand expanding space.

    Moving away, not accelerating.

    Effort to get us all on the same page (balloon analogy)

    Maybe galaxies are not moving away but shrinking. The end result would be the same (redshift , etc...)

    What are some other ways to solve the equation x^3+y^3+z^3+t^3=1999?

    Seems you're right!

    Spacetime: Stretching or Growing? Or

    What we call space expansion can as well be viewed as matter contraction. As particles and galaxies shrinks wherever they are, they appear to be moving further apart. Are space expansion and matter contraction two exactly equivalent ways to describe the same phenomenon? Maybe they are, but...
