    DE appears to be a property of space that acts in accelerating the expansion of space.
    DM is matter that does not interact via any method except gravity...That is why it is invisible.
    Obviously like any baryonic matter, it was created at some time in the past, post BB, as the universe underwent cooling and expansion.

    Will watch some other time...too long! What is the relevant point you are trying to make anyway?
    [3] Is the Universe Finite or Infinite? We still have no convincing evidence one way or the other about whether the universe is finite or infinite. All we can deduce is that it is very very big, and near infinite in extent and content. "Near infinite" is my own description of it.

    [4] What is "Nothing" from whence the BB evolved? We can only speculate, but according to Lawrence Krauss and his book, "A Universe from Nothing" the quantum foam could be as nothing as is possible to get, or quantum foam is effectively nothing.

    The Planck scale: relativity meets quantum mechanics meets gravity.
    https://newt.phys.unsw.edu.au/einsteinlight/jw/module6_Planck.htm

    I understand this to mean that Planck Length and Planck Time are Universal constants, i.e. the smallest effective relative values which lie at the foundation of Reality.

    Planck Units

    Hazen lays out three probable mechanisms for Abiogenesis. (save time by starting @ 12:00) It seems to me that this great question of Abiogenesis cannot be answered in a few short sentences and must be examined from the purely chemical state of the universe, along the formation of biochemical compounds and the "natural selection' of "efficiency" which seem to prefer "utility and symmetry", regardless of the medium.
    That's why I prefer the term; "permittive condition" over "nothingness".
    A permittive condition may be infinite in scope as it has no size limitation, yet be permittive of dynamical functions.
    Despite Krauss' creative use of the word "nothing", the definition of "nothingness" really precludes the assignment of any property, such as infinitely small or large or dynamical in essence.

    From your link.....
    It's possible that we'll never be able to measure them, so any threat posed to relativity is distant and perhaps even hypothetical.
    Again, I don't see anything too creative about it, other then yes, speculative, but irrespective of your view of nothing, quantum foam is damn close and possibly as nothing as one could get, that had existed for eternity prior to the BB.

    1. Why is there something rather than nothing? Why is there such a thing as reality at all, rather than the total absence of... anything and everything? Why does existence exist in the first place? That's the ultimate question in my opinion.

    2. What is mathematics? Why does it seem so... objective, rather than subjective? Why is a proof that's valid for one mathematician valid for all of them? What kind of reality do mathematical truths have? How is it that human beings can know about mathematics at all? What's the source of that knowledge?

    3. What are the laws of physics? Why are they what they seem to be and not something else? Are they descriptive or prescriptive? Why must physical events seemingly always conform to them? What kind of power do they seemingly wield over what can and can't happen?

    4. What is the connection between evidence and conclusions? It isn't exactly deduction, no matter how many times Holmes said it was. So what is it?

    5. What are linguistic meaning and reference? How can some sounds or some ink squiggles on paper mean something? How can some squiggles refer to something else entirely? What's the connection between them?

    And many more...

    Some we may never know and will always simply pontificate phylosophically on......others are answered to at least within the bounds of our models.
    Mathematics? I'll stick to my favourite answer as being the language of physics.

    Or perhaps existed for a single dynamic quantum instant prior to the BB?

    This may be of interest;

    HOW DID THE UNIVERSE START AND EVOLVE?

    WMAP determined that the first stars in the universe arose only about 400 million years after the Big Bang. But what made the stars?

    Quantum Fluctuations are the random nature of matter's state of existence or nonexistence. At these incredibly small sub-atomic scales, the state of reality is fleeting, changing from nanosecond to nanosecond.

    I have no quarrel with that. I just change the paradigm to read; The language of the physical relational values and functions of the universe, regardless of human observation or understanding.....

    Well it finally looks like you all are beginning to agree not only on terms, but also on theory, logic, as well as what Is arbitrary, inferred, unprovable, and unproductive. Great leaps in my opinion.

    I think I will enjoy the peace and not start any argument that could potentially lead the way in solving some of these unknowns.
