    Sure I do! There are also many hypotheticals of gravity, but GR is still the overwhelmingly supported one. And an otherwise great Astronomer, a bloke called Fred Hoyle, dismissed the BB and pushed a "Steady State"model.

    The "Round Earth Theory" isn't universally accepted either.

    The Big Bang is the current universally accepted scientific theory. That doesn't mean that there are (plenty) of issues associated with it that are problematic or that need further explanations. There isn't another comparable theory in this realm though.

    In fact he derisively "named" the alternative theory "The Big Bang".

    A common mistake in fact, at least according to Hoyle himself. "Hoyle explicitly denied that he was being insulting and said it was just a striking image meant to emphasize the difference between the two theories for the radio audience"
    Hoyle although obviously a top notch scientist and did plenty of work re the nucleosynthesis of heavy elements, and stellar life spans, did have what one may call an agenda. As an avid Atheist, he probably disliked the BB because it forecast a "beginning" "The reason why scientists like the "big bang" is because they are overshadowed by the Book of Genesis. It is deep within the psyche of most scientists to believe in the first page of Genesis"
    Although I see any beginning as a bit of a furphy, since the BB only applies to the observable universe anyway, but perhaps that's a later interpretation.
    Both highlighted parts are from.....
    Hoyle also pushed Abiogenesis via Panspermia.....

    A wikipedia article but quite interesting and revealing of this pretty rare scientists and human being.

    Which at least to me anyway, tells us the greatest asset of the scientific discipline, is going where the evidence points to, irrespective of any supposed interpretation/s. As a tin lid in the fifties and early sixties, there were actually three competing theories or hypotheticals for how the universe evolved/began...The BB of course, Hoyles "Steady State" and the Oscillating model. From memory the BB quickly rose above the pack with the discovery and verification of the CMBR at 2.7K.

    It's my observation that you spend a lot of your time here complaining. If you don't win friends that way, the problem might be on your end. Just a thought.

    My earlier comments stand and nothing further to add. Continue here as a monologue if you wish. Our dialogs never lead anywhere useful or end well - this occasion is no exception.

    Oh look they mention
    ......... Moreover, they say nothing at all about the point we call “now” — a special moment (or so it appears) for us, but seemingly undefined

    when we talk about the universe at large.
    my bold

    and

    .......The resulting timeless cosmos is sometimes called a “block universe”

    but not sure if their timeless is same as my non existent TIME

    Oh and where have I seen this before?
    The future does not exist

    The directionality that we observe in the macroscopic world is very real: Teacups shatter but do not spontaneously reassemble; eggs can be scrambled but not unscrambled.

    My thoughts on the above

    No such thing as directionality (since TIME is non existent - sorry if I am harping on)
    What is being observed is NOT directionality but only (merely) CHANGE and while teacups do indeed shatter, they do not spontaneously CHANGE and unshatter (no direction implied)

    then entropy is just as likely to increase going backward in time. But no one believes that entropy actually works that way. Scrambled eggs always come after whole eggs, never the other way around.

    There is that bugbear directionality again. It really does not arise from the viewpoint of only NOW being in existence

    I skipped though the rest but didn't note anything outstanding to comment on
    If you think I missed a vital bit please cut and paste (small section only please)

    Thanks again for the link

    May my humble thoughts keep you busy

    PS - any luck finding a property of TIME?

    My theory of Light is that there is no light. It's DARK that is real. Light is just the absence of DARK. That's my theory. D-D-L

    There is no light. It's an illusion. There is brightness but no Light.

    If I imagine a world with no hypothetical situations does it instantly disappear because it itself is a hypothetical situation?

    It does not because the world never existed in the first place (it was not created.)

    If you imagine a world...it's an imagined world. There is no puzzle to put together here.

    How can time exist with no energy ?

    This suggests that time is not based on the physical .

    But my imagination exists in reality. Should we stop imagining hypotheticals just to keep from making more puzzles?

    Most theories start with something imagined and gain traction from evidence found that fits the narrative.

    So imagination is the beginning of puzzles not the end.

    It does not disappear because we live in a reality where we are free to imagine unreal ideas?

    Or it does not exist because a place without energy it is impossible for anything to exist.

    Just to clarify.

    I havn't yet mentioned the most ideal and likely situation of the interchangeability of space and time. That is inside BH's. This gives a description, highly mathematical but supportive of this seemingly bizarre concept of the interchangebility of space and time.

    Imagine no

    pad

    Space and Time can not be compared . Interchangeable .

    Both are entirely different .

    Space has room , Time is about movement of physical things . Within space , within the room . Because of the Nature of any physical thing .

    Your imagined "world" is based upon this world. Two cannot exist at the same moment.

    Time is a form of space. To "have time" means you haven't died yet. However it also means that you must die at some moment in the future. We are dying, and must be for TIME to exist.
