Article: Scientists in a race to discover why our Universe exists

    Epicurean philosophy says that the Universe has no beginning and no end.

    Article excerpt:

    "The current theory of how the Universe came into being can't explain the existence of the planets, stars and galaxies we see around us. Both teams are building detectors that study a sub-atomic particle called a neutrino in the hope of finding answers."

    This article is about the Deep Underground Neutrino Experiment (Dune):

    Scientists in race to discover why our Universe exists
    Researchers in the US and Japan are competing to explain the existence of the planets, stars and galaxies.

    I'm glad you asked! :)

    From my perspective, the Epicurean kósmos (which is defined as having a beginning and an end) is most conceptually-similar with the contemporary "Observable Universe". I contrast that against that idea of the metakosmíos (which contains an infinite number of generative and decaying kósmoi), which, I think, is best exemplified by the hypothetical concept of a "multiverse".

    For that reason, I've left kósmos untranslated in my recent project. It's not quite a "world", but it's not quite a "universe", and I think it might be best to keep each idea contextualized in its history. (The same, I think, is true of the modern word "atoms", which refers to divisible amalagamations).

    Speaking for myself only, i consider this to be the intersection of philosophy vs "science," the latter word of which i find to be a word that is very ambiguous, easy to employ for political purposes, and thrown around far too loosely even by people who don't think they have an agenda. Some of that is discussed here.

    It doesn't bother me that the "predominant" theory is that the universe had a beginning because I take the position that these proponents are not addressing the question of "what caused or what was prior to that beginning." Unless they are willing to go on record that "what was before the beginning was god" - which is really what they are implying - then they are just kicking the ball down the road and adding nothing to the conversation. The question is not "how many times has our section of the universe knowable to us expanded and contracted. The question is "what put the whole thing in motion in the first place" and that is best answered by something to the effect that in all human experience nothing has ever been observed to come from nothing, and as a matter of principle I'm not going to entertain speculation without evidence.

    As Eikadistes said, much of the apparent turmoil comes from people taking the "observable universe" and not limiting their conclusions to "the observable." Yes, the "observable" universe may be expanding and contracting, but that does not mean that what is beyond the observable is expanding and contracting in the same direction. Epicurus is talking about "the all" when he says that the all is eternal and infinite, not any particular part of it.

    I was raised at a time when "universe" was meant to refer to "the all." I realize that people today talk about multiverses and the like, but that just kicks the ball down the road again. I see no need to depart from traditional usage -- universe means "all that exists" and I see no persuasive evidence that indicates that Epicurus was wrong that "the all that exists" has existed for ever, and will exist forever, and that it has no limit in terms of space or time.

    You'll find rhat in Epicurus' own time he and others (Lucian for example) were engaged in battles with the "scientists of their day" who were using mathematics and geometry to speculate that the stars were gods, and reach conclusions that contradict basic Epicurean physics as to the natural basis of the universe. There are always going to be such conflicts, just as there are now, and the way to deal with them is through understanding Epicurean canonics as standards of proof for what is and is not real, and how you deal with theories based on limited information which would appear to contradict fundamental conclusions that are based on repeatable observation and have proven their usefulness over the ages. One such observation is "nothing comes from nothing" and until an instance of that can be established to occur then nothing that contradicts that premise should be entertained to even be possible.

    All we know is its current era did. Could it be infinitely expanding and contracting without beginning without end? It's nothing that can be ruled out. Right now, there's not enough evidence, although the cosmological constant doesn't seem so constant as it seems to have different values in different parts of space over time. If it slows down the universe will eventually stop expanding and contract.

    The universe's accelerated expansion might be slowing down

    The principle of multiple explanations comes into play. Very Epicurean. ;)
