    The following article confirms what I have been thinking for sometime now. I consider this proof that black holes that start as stellar sized BH's do have a life cycle where they grow larger over time. A great deal of time and that the average new stellar sized BH in the average galaxy will grow in a predictable way. I'm sure there are some exceptions. But I'm betting just about all Super Massive BH's were in existence before the natural big bang event that was the start of our local universe. Sure this is only my thinking, but I have seen other articles that indicate a few others have brought this topic up to be explored. If I can find them again, I'll post them.

    Not sure on your SMBH's being in existence before the BB...Could you elaborate on your thinking behind that?
    Medium sized BH's though have never really struck me as being in any doubt.
    Stars form in systems generally...binary, trinary, quadruple etc......
    In fact our Sun is somewhat of a rarity, being in a single system.
    I simply envisage small stellar BH's, growing to medium size, and than via the accretion system, swallowing other BH's and matter, and arriving at the SMBH variety.
    There was an argument re not enough time for this to happen, and it has been debated in a past thread. That was quickly dispelled though.

    If you believe that our local universe is a natural event that happens in other locations so that there are many universes and that this process has been happening for a very extreme long time. Each of these other universes will most likely resemble ours which means they will all create BH's that will out live all the stars. Really BH's don't much care if there are stars or not. They will still go about their business in the dark. Nobody really knows what could cause a Big Bang event, but it seems reasonable to speculate that where ever they happen, there are BH's going about their business from previous universes that have been around long enough to have gone dark. I'm pretty sure no Big Bang event would cause BH's any trouble what so ever, and in fact would create all the new Hydrogen which would use the existing BH's as places for new star creation. I believe it's possible that some of the largest BH's in our local universe may have experienced multiple Big Bang events already.

    You also, mentioned that topic about some BH's which appear to have been greater than 10 billion solar masses that were shown to have been in existence within the the first 2 or 3 billion years after the Big Bang event. From my point of view it's much easier to believe those Black holes didn't get that big in that short period of time, and that only leaves the possibility that they already existed before the Big Bang event.

    Here's a couple of recent BH papers................

    Nice article......I did read it on physorg a while back and may have even started a thread on it.
    The thing is according to current data the BB was an evolution of space and time, [spacetime] and we know BH's occur in spacetime through critical spacetime curvature in the presence of mass.
    There was also some "noise" a couple of decades ago about a star that was older than the Universe/BB itself. After error bars were taken into consideration, the anomaly was explained.
    Stars/galaxies started to form within 400/500 million years after the BB also.

    If we do live in a multiverse and other Big Bangs have happened, it could be possible that two universes such as our own local universe could eventually expand into each other. I can just imagine how our scientists would interpret the observations going on in the merging area of space. Now imagine one of the expanding universes is a few billion years older than our own local universe?

    Please read the following article and see if it could relate to what I just said.

    There are still things we see that at the time we are unable to explain.
    There also what I recall is known as a "cold spot" in the CMBR that s yet, as far as I know, is not fully explained.

    Relating to what you said, sure, its possible. I like the speculative scenario that says our BB is actually the arse end of a White Hole, and BH's within our universe actually lead via ERB'S and wormholes into other newly created universes.
    What is awesome is that we are able to speculate such things, based on our current knowledge.

    I support your general thinking in this thread, and I cover similar ideas in my threads out in the Fringe. The Alternative Theories sub-forum is ideal for the kind of thinking you present, and was set up for discussions like this. I would like to contribute beyond giving my support, but my ideas are almost all alternative, lol.

    Nothing wrong with that at all, as long as one recognises they are alternative and not be fooled into believing they have trumped Hubble, Einstein and others.
