    That's a somewhat difficult question. The Doppler shift that we observe today is not (primarily) determined by the velocity the observed object had when light left it years ago. The shift has come about due to space expanding as the light travelled from the distant object to us. You can think of it as the wavelength of the light being gradually stretched as the light moves through space.

    it seems you have already defined the unknown universe in your own terms and now we may as well stop talking about it.
    thanks !

    The content of that quoted post was from here, posted by DH, yet you gave it as mine.
    How strange.
    Maybe you're taking too much soup.

    And the terminology "defined in your own terms" is misleading.
    There are other possible terms than the scientific one?
    That are actually valid for a question like this?

    I've never heard that 15 billion year expression but I do know this. The universe continuos therefore there is no such thing as a side and there is no such thing as middle of the universe. Ok, the location where the big bang occured is where every piece of matter came from but it is not the center/middle of outerspace.

    if the numbers were finite (of matter,space,energy etc of big bang )then there is a center.
    If not(the infinity theory) there can't be no end or center.

    Not necessarily. You are implicitly assuming that space is Cartesian. It isn't.

    I dont know what space is(so far),what is it?
    If the universe if expanding that means its not infinite(and that the big bang had finite numbers)...i could only *speculate*(fwith my human casual life-logic) that there is a center...

    Center is not exist at 4D, But we can say the center at 3D.

    In Earth, We live at the 4D. But we can say 3D center of earth.
    Also we wish know center of earth in curiosity. though, it has not means specially

    In this view, can say the space center of universe? and where?

    add menas in physics, fine the center of mass in universe1(our universe)
    and space(geometrical) center is same to mass center? space center is same to bigbang point or region(3d)?
