    [1] How did the exact process and methodology of Abiogenesis Arise?

    [2] Does any life exist elsewhere other then on this fart arse little blue orb?

    [3] Is the Universe Finite or Infinite?

    [4] What is "Nothing" from whence the BB evolved?

    [5] What is the actual state of matter/energy at and below the quantum/Planck level at the core of BH's

    [6] Will we ever formulate an observably verifiable QGT?

    Any more scientifically based questions worth considering?

    Looking back to the birth of the Universe the Big Bang seems to be the best explanation

    Quantum Foam spread throughout the Universe (a type of ether???) and is it required for light to be able to travel??? ie if Quantum Foam not in place, and a TRUE NOTHINGNESS was the order of reality could light travel through a TRUE NOTHINGNESS?

    Not sure about a singularity being smaller than a atom

    *****
    Physicists are undecided whether the prediction of singularities means that they actually exist (or existed at the start of the Big Bang), or that current knowledge is insufficient to describe what happens at such extreme densities.

    https://en.m.wikipedia.org/wiki/Gra...e singularity,depend on the coordinate system.
    *****
    So Quantum Foam spread evenly throughout a TOTAL INFINITE VOID gets a ✓ from me

    So the next question becomes

    Why did some of this Quantum Foam decide to group together to form a singularity (or a whatever)?

    Alex, as another Aussie of reasonable thought, while disliking the BB model, still admitted it being the best we have.
    But I see his view on that as similar to Hoyle, who also disliked it and proposed the Steady State. The point I believe responsible for that dislike, is that it denotes a beginning, and a beginning that as yet GR and the laws of physics is unable to explain, or even apply to, and consequently a point where the religious fanatics and God botherers are able to hang their hat on and claim as the work of an unscientific, mythical God.
    An interesting book to read is Lawrence Krauss' "A Universe from Nothing" ...In it it is surmises that the quantum foam is actually nothing, and we can never get anything more nothing then that.
    The Singularity of infinite qualities, like the gravitational Singularity your link describes, is now as far as I know, rejected by most physicists.
    But we also have a Singularity as defined by where our laws of physics and GR do not apply. That starts at the quantum/Planck level. So while GR tells us that once the Schwarzchild radius/limit [equal to the EH] is reached in a collapsing mass, further collapse is compulsory. Add to that fact that the same GR and all other laws fail us at that point of the quantum/Planck level, and it allows some speculation that the collapsing mass/energy reaches a point at or beyond the quantum/Planck level, where its nature is unknown to us...a surface of sorts in other words, at or below that level.
    I like it, along with Krauss' speculation re "nothing" and the quantum foam.

    That something is a roiling collection of virtual particles, collectively called quantum foam. According to quantum physicists, virtual particles exist briefly as fleeting fluctuations in the fabric of spacetime, like bubbles in beer foam.Aug 5, 2017

    https://www.livescience.com/60053-is-space-full-of-quantum-foam.html

    This is perhaps a language problem for me.

    The above extract is in part of the answer to "What is quantum foam made of?"

    That something is a roiling collection of virtual particles, collectively called quantum foam

    So far so good, shorthand down to -
    quantum foam = a roiling collection of virtual particles

    Got it

    But then comes

    According to quantum physicists, like bubbles in beer foam, virtual particles exist briefly as fleeting fluctuations in the fabric of spacetime, like bubbles in beer foam

    Wait what???? Nothing said about fabric of spacetime. What is fabric of spacetime made of?

    I thought quantum foam = a roiling collection of virtual particle meant quantum foam = a roiling collection of virtual particle IN NOTHINGNESS

    Who slipped in fabric of spacetime?

    And then we get as a comparison

    like bubbles in beer foam

    Have news for you quantum physicists beer foam is made of beer

    For your like to work your quantum foam should be made of quantum

    Must be coffee moment

    Made with one tiny tiny bright spark here

    Quantum foam is probably spacetime observed at the Planck/quantum scale.
    https://en.wikipedia.org/wiki/Quantum_foam

    An Interesting extract from that....
    Experimental results[edit]
    In 2009 the two MAGIC (Major Atmospheric Gamma-ray Imaging Cherenkov) telescopes detected that among gamma-ray photons arriving from the blazar Markarian 501, some photons at different energy levels arrived at different times, suggesting that some of the photons had moved more slowly and thus contradicting the theory of general relativity's notion of the speed of light being constant, a discrepancy which could be explained by the irregularity of quantum foam.[5] More recent experiments were, however, unable to confirm the supposed variation on the speed of light due to graininess of space.[6][7]

    Other experiments involving the polarization of light from distant gamma ray bursts have also produced contradictory results.[8] More Earth-based experiments are ongoing[9] or proposed.

    On number [2] one must ask, is there intelligent life elsewhere? and is there intelligent life elsewhere, could some of it be far in advanced of the knowledge we on Earth have so far obtained?

    I would suggest to use the term "permittive condition" in place of "nothingness"
    Causal Dynamical Triangulation.

    I refer to Robert Hazen "CHANCE, NECESSITY, and the ORIGINS OF LIFE"

    start viewing @ 12:00 (to avoid lengthy introduction)

    A "permittive condition" ?
    There is no "below" Planck level.
    Abiogenesis? See Robert Hazen above.
    CDT?

    I feel another back and forth seesaw English language debate coming on so let's nip in its budding stage NOW

    WHY EXACTLY IS NOTHINGNESS NOT A PERMITTIVE CONDITION?

    Rhetorical question - do not answer

    Blah blah blah, not read, links not checked

    Nothingness is "not-being". A permittive condition is "being". I see a philosophical difference, not an English language debate. .....

    I asked you not to reply to the Rhetorical Question and it seems you cannot understand a simple request hence

    I AM OUT

    Parting shot

    *****
    Their admittedly controversial answer is that the entire universe, from the fireball of the Big Bang to the star-studded cosmos we now inhabit, popped into existence from nothing at all. It had to happen, they say, because "nothing" is inherently unstable.

    From

    http://www.bbc.com/earth/story/20141106-why-does-anything-exist-at-all

    *******
    "nothing" is inherently unstable. indicates to me NOTHING IS BEING TREATED A SOMETHING AND IS THE PERFECT CANDIDATE FOR BEING A PERMISSIVE STATE

    PS - THIS IS SCIENCE NOT ENGLISH OR PHILOSOPHICAL
