    and when you asked, what happened, where are they now?
    that picture came from a universe that was 14 % it's present size, and now 25 % ot it are visible to us now, ALMA shows the same array.

    it has expanded 13.7 billion years in all directions, the radius from the BB, so the diameter is ~27 billion light years, as the crow flies 86 billion years in circumference, ( the same numbers were posted by others, based on mainstream science: 90 billion by seattle @ post#30 for example. ). thank you.

    I dont see 30 posts here???
    But I do think "mainstream" has a diameter of approx 95 billion light years.
    I gather your model has something different.
    Thats ok with me but I will check for myself with a ruler.

    I was referring to your post # 2 in the 8. December "ALMA" question, seattle's post#30 there too.
    Do not want to promote fringe ideas on this amateur science forum.
    86 billion light years does not take inflation into account. faster than light expansion would bring it to 95 bly. in extent I guess. What is 10 billion years among friends?
