    pad , it is the theory , the thinking that matters . Not the name .

    Look into the theory , with an open mind .

    How do think your " past giants of thinking " thought what they did , because they thought with an open mind .

    Those who went before were surpassed by those in the now , at the time and at the present .

    Thinking evolves , it isn't frozen in the history of thought . You know this to be true pad .

    river, I will take you back to page # 28, with this basic image of the 4 "horizons" made by the radius on a sphere.

    Please Register or Log in to view the hidden image!



    the total horizon is more like this : https://en.wikipedia.org/wiki/Spherical_sector,
    anything that emitted radiation within the volume of that cone (actually the radius of 13.8 billion years from #5, even to the apex #4, more then the straight sided cone. ) would be within the time horizon. A particle without movement would move and emit to a point close to us now. one moving at the speed of light be seem to be coming from the perimeter along the membrane #3. at the intersection with line #9. so,
    It is only one universe, having gone in all directions since the beginning. In this model, the All has >4 locally separated time horizons. to see it all. but,
    If space expanded faster than "c" imagine the white areas in the photo to be even bigger, because then it would be space horizons based on the inflation theory. and
    Yes this result of the model is presented as fact, it is open to question, but here it is, as defined.

    how about Dark Matter then?

    Here is an item that would require time to exist before the Big Bang:
    Johns Hopkins University. "Dark matter may be older than the Big Bang." ScienceDaily. ScienceDaily, 7 August 2019. <www.sciencedaily.com/releases/2019/08/190807190816.htm>.
    Now, -- matter, even if "dark" is just another form of energy. so: if it existed before the Big Beginning it hang in 'timespace', and coexist with energy in 'energytime'.
    thinking the unthinkable. the pre-beginning scenario, unlimited.

    Yeah I know about Inflation, and it helps explain a couple of shortcomings of the BB, but as yet, as far as I know, we have no direct evidence for it. And in most scenarios it occurs about 10-35 seconds after the BB. Perhaps your article is referring to another hypothetical version called is "eternal Inflation"

    Paddo, It is not my article but from John Hopkins University. No, it is not about the BB and the ensuing inflation, it is about Dark Matter before the BB, and by extension the time that had to be available for the pre BB DM to exist in.

    Like I said eternal Inflation?
    And anyway, it is nothing more then a speculative scenario of which we probably can never be sure of.

    Here is a snippet from Wiki, "eternal inflation":
    "Although inflation is generically eternal into the future, it is not eternal into the past." Guth detailed what was known about the subject at the time, --"
    Eternal inflation would therefore imply eternal future time.
    In the expanding through time membrane model, time is considered eternal also into the past, prior to our Big Beginning, because the energy it took for the universe to exist with it's time it has to have is uncreated.
    The Pad we live in Paddo, is expanding and floating in a big unlimited sea of time.
    Whether the expansion of our universe in space & size is inflationary, eternally? -- work for the experts. but
    The expansion into the future, into time#1 is happening apace.

    Probing the Universe's Dark Energy.

    story on BBC, " it is embarrassing to live in a universe of which 95% we do not understand."
    The allegation on this threads's model "Bubble expanding into time" is, that
    infinite time as a first dimension is home to infinitely old uncreated energy, and it is absorbed as the universe expands into the future.

    This ur-energy existed in timespace before the Big Bang, and is still stretching to infinity and it appears everywhere , possibly as the "dark energy" as every local in the universe moves into the future and now encompasses more volume in "timespace"

    here is a nice image that would picture the model of a universe expanding into timespace from a central point beginning. From the New Scientist Article,
    --the universe is round or flat!

    Journal reference: Nature Astronomy, DOI: 10.1038/s41550-019-0906-9
    but you could never come back to the same place, because it does not exist any more, the universe has passed through it for good.

    And the whole moves forward in time in all global directions, this is the expansion phenomenon. The whole moves forward in time in all directions through a single one-way timegate. The gate closes after the whole has passed and becomes inaccessible from a later spacetime coordinates.
    Determinism forbids the time travel, IMO. The universe would have to contract to a prior state in order to account for spacetime expansion into the future. Consider the implications.

    wfy,
    the expanding curved membrane of the present leaves nothing behind in the past. even if the universe were , in a pull-sating mode (freudian slip welcome) to a new, different point in timespace, it would not have to have a backward re-run of past events. they are gone.
    [/B]
    wfy,
    no, prior size yes. prior state no. but
    perhaps giving up dark energy it absorbed during it's expansion into energytime.
