Hey guys, what are your thoughts on the existence of extraterrestrial life and the potential involvement of governments in concealing or studying such entities.

    I meant a strange attractor, but I think it also has prostitutes properties of a strange loop.

    A strange loop is a hierarchy, or heterarchy, where as you proceed ‘up’ the hierarchy, you eventually arrive where you started.

    A strange attractor is a system which, although never quite having the exact same state, cycles around the same general set of states. One way of thinking of this is “a loop which never quite mets up with itself”. An interesting example of this would be a three+ body gravitational system where the bodies are of comparable mass, and no stabilizing elements are present. Odds are very against them actually striking each other, but orbits are virtually completely unpredictable. Nevertheless, they won’t eject any of the bodies, so they will always be in the same general region.

    As applied to the universe, you could set the ‘laws’ of the universe as values on a manifold, and these ‘laws’ would flex and shift as the overall state of the universe changes, but the universe would cycle around within a probability niche - a strange attractor. There’s also a potential it could leave that probability niche and ‘fall’ into, or enter into, another. One such probability niche would be the very strong tendencies of the universe - the ‘laws’ of the universe - as we know them.

      My training is in applied mathematics, so I’m only conceptually aware of strange attractors. It’s my understanding that they are chaotic systems that tend towards a stable state. As such I’m a little skeptical of the claim that the universe itself is a strange attractor, since it is broadly predictable and hence not chaotic, and it’s expanding and thus not tending towards stability!

        I’m referring to the laws of the universe, which have not always been consistent. A strange attractor can form states that are temporarily dynamically stable - and for something like the universe, we may not notice any small changes to ‘constants,’ as we are directly subject to them (including our tools of measurement). Aside from that, change is likely so slow that we may not even notice it.

        Nevertheless, if the big bang is in any form to be believes, we must accept that the universe’s basic laws can change, and yet they enter states where they do not noticeably change. If the pattern of the rest of nature holds (massive numbers of similar forms and structures distributed over time and space, where rough repetition along a common theme is a common theme), the universe will probably do similarly.

        What would be incredibly odd would be:

        • something came into existence from nothing
        • that something happened for a while
        • that something basically stops happening due to even distribution of energy throughout space
        • end of story

        Or

        • no consistency whatsoever

        Either of those seem unlikely. But, of course, I live in this universe, so I could be biased. :-)
