Cosmology is fascinating because it seeks - even if indirectly - to demonstrably answer the ultimately meaningful questions: How did we get here? Where did the universe come from? How did the universe begin? Why did it happen (which implies that there was even a purpose behind it)? Was there a Creator? Reading articles like the one attached is like reading "Incomprehensible Calculus for Beginners." You can understand the first few pages but then you’re totally lost and hoping for more pictures. Still it gives you a picture of where human intellect has taken us thus far. www.quantamagazine.org/physicists-debate-hawkings-idea-that-the-universe-had-no-beginning-20190606/But you start to feel that these physicists with their multidimensional concepts and abstruse mathematical formulas may only be kidding themselves that they will find the answers they seek. Even if they demonstrate that it all started with a "no-boundary wave function” (we all know what that is so I won’t waste your time belaboring the obvious) the inevitable question will remain " Where did the wave function come from?" Even if they come up with some unfathomable mathematical equation that they claim explains the origins, the question will be " How do you know that reality necessarily conforms to your mathematical conclusions?"
I have come to accept Matthew Fox's line from "Emperor" regarding Hirohito’s responsibility for WW2: "We don’t know. We’ll never know."
I realize some of you will say you "know" it was the work of a Creator, but believing and knowing are two different states of mind. "Knowing" is a demonstrable certitude. "Believing" is a movable scale culminating in certainty. Descartes "I think, therefore I am" is a certainty, but drawing any conclusions (such as the existence of a Creator) from that is simply a belief. His logical sequence may be correct, but it is not proven, not a QED. Anyway, this may be boring as hell to most of you but I find it fascinating. ..................So what’s AOC up to?....................................Luca

OK...I bit, and I'll read it.
I will say this though, I thought you said something about cosmotology, which makes your last line pretty funny.
And I agree. Even though she provides regular fodder, I'd much rather watch a Little AOC parody instead of I need an AOC fix.
Time for some better subject matter.
Thanks

After reading that, I'm convinced I'm a lazy moron. That's well beyond my scope of understanding today. Doesn't mean it will be a few months from now, or maybe it will still be the case.
My takeaway is along with Hawking's point of what's South of the South pole when referring to the importance of understand what came before the Big Bang Theory.
If I had an idea why this is important enough to spend a few lifetimes trying to figure it out, I might take an interest in the quest.
Clearly this is not trivial stuff... I just don't get the purpose.
Need some help with the end game here, Doc.

I am the type of person who takes joy in knowing details about subjects that interest me. While the subject of the universe and why/how are we here is something I find interesting, the details hurt my head. I believe there are answers, I just don't know if my current consciousness has the ability to understand it.
There is something comforting in believing that while I don't know or understand now, I will in the afterlife. Or, I won't...

Did anyone else read that 2nd paragraph and suddenly hear the Bug Bang Theory theme song playing softly in their mind? Our whole universe was in a hot, dense state Then nearly fourteen billion years ago expansion started, wait The earth began to cool, the autotrophs began to drool Neanderthals developed tools… (You’re welcome) I then experienced a deja bu of sorts, back to several conversations we had in TOB, raising some of the same issues as are discussed in the article, name,y, “what pre-existed the Big Bang?” And, from that inquiry (?), one suggestion of a scientotheological nature we called “theological evolution” (a rabbit trail I will not go down here). I heard an explanation by a guy named Ken Hovind (never heard of him before or after I saw this video) . He explains Time, Space, and Matter have to come into existence at the same instant: If you have matter but no space, where would you put it? If you have space but no time, WHEN would you out it. A problem my puny brain has/had with Hawking’s infinity posit is two-fold: - It can never be proven or refuted; and
- He ignores that time passes whether or not there exists a mechanism for calculating or measuring it.
Sometimes, I further observe, we (meaning”mankind”) go to great lengths to avoid the Occam's Razor in all this (That the simplest explanation, regardless of how improbable, is usually the more accurate): IF the Big Bang is accurate (and, in fact “all this” did expand from a singularity), then we should be able to mathematically calculate backwards to that single point, as was done by... OH GREAT, Now I’ve forgotten who did that... maybe Hubble or, before him, Alexander Friedmann ? ... anyway, it has been done, which, also in my puny mind, gets us back behind what is known to the original question, if time, space, and matter came into being at the same moment, what pre-existed them... and, to me, the more important question of how did they come into being?
finally, I do want to take exception to how you, Luca, defined “know” versus “belief.” But I do not expect anyone to agree with me here: A believer in Christ, that is to say, a follower and devotee of God, has another dimension to that question, Faith. As the book of Hebrews states, “Now faith is the substance of things hoped for, the evidence of things not seen.” To me and other believers in Christ, “faith” is knowing but without the evidence others might require. It is not even easily explained and I know I have not done a good job of it, but to suggest I only believe is misleading: I believe the elevator will take me to an upper or lower floor, but until I put that belief into action, it will remain a belief. I will “know” the elevator will deliver me when I have faith enough to actually get on the elevator.

Dave - wouldn't your threshold of "knowing" be the same thing we take issue with liberals about? Don't they also "know" their position to be true, and subsequently act upon it?

In point of fact, I’ve had this same argument with several of the ardent leftists over at TOB, as their only frame of reference was “know” with a scientific certainty. they did not... and likely still do not understand the “know” of which I speak. I explained it to them just as I did above, but until they embrace Scripture, they lack the capacity to understand what is essentially a third definition to their “believe” vs. “know” conundrum: That of Faith. So, now that I say it out loud (or “type” it out loud), maybe I don’t so much take issue with Luca’s definitions as I want to add to the category....

Oh, I forgot the other part of your question...
Liberals “knowing” they are right will likely add a fourth to the category: To them, “Know” might be more akin to “feel” or “prefer.”

Would it be correct to simply say the more you believe something, regardless of any objective "proof", the more you "know" that thing to be true?

The dictionary defines "faith" as: "strong belief in God or in the doctrines of a religion, based on spiritual apprehension rather than proof."
If you "know" something to be true, then it is not "faith." It is "knowledge."
The very word faith means a belief without proof. Your faith may be very strong (and it may be correct) but it still does not qualify as what we call "knowledge", by definition.
We are not utilizing the same definition of the word.
I only posted the article because it's interesting what theories are currently being entertained for the origin of the universe. They include equally incoherent and unprovable concepts such as additional dimensions, a beginning of time (before which there was none) and a Big Bang created apparently out of nothing. I remember having circular arguments with Fordama (He who is blessed with Unwavering Certainty) because he has absolute faith - and that's what it is – in those theories while at the same time belittling faith in a Creator......... when in fact both require "faith."
I don't think he ever grasped the nuances.....................Luca.

Fordama would not accept that both were beliefs and that atheism is essentially a religion. In his mind, your beliefs are fairy tale stories and his beliefs are rock solid science.

I think you men are vending man’s definition(s) of Faith which always seems to ignore the spiritual aspect.
Of course, I have faith my wife loves me, or that my car, properly maintained, will get me from Point A to point B... but that is not the faith spoken of in the Bible.
Again, as the Book of Hebrews explains,
You are completely correct in your understanding of faith from our earth-bound perspective.
I am not being critical and trying to not be condescending when I say, that is not the faith of which (I understand) the Bible to speak. It is a different level, if you will.
I have had people tell me, “then you don’t know God exists, you just believe he does.” To which I respond, “uh uh: I know ... with unwavering certainty He exists.”
I should also point out, this faith of which I speak is not something of my own doing. Nothing I’ve perfected over years of testing and trying. This faith, this unwavering certainty, comes from God.,

Dave - I'm having a hard time differentiating between faith based "knowledge", be it of the Creator or the origins of the cosmos, and earth-bound scientific knowledge "water molecule consists of 2 parts hydrogen, and 1 part oxygen". A topic for another thread so as not to further hijack this one, but my grounding values has me thinking faith based knowledge lacks objectivity, and that's ground zero of the biggest problems we're facing as a country, and perhaps the world.
Regardless, this topic of the origins of the cosmos is thought-provoking. Luca, can you summarize what was contained in that article in a way that a 5th grader could understand? I need some type of foundation to start this quest.

Luca, can you summarize what was contained in that article in a way that a 5th grader could understand? I need some type of foundation to start this quest. For Dave, I know that 2+2 = 4 because I can add them together myself and reach that conclusion. If I subtract 2 from 4, I get an answer of 2. If I add +2 to both side to that equation I’ll wind up with 4. It is therefore proven and I know it’s true. I do not know that E=mc2. People far smarter than I do believe it and can mathematically demonstrate it, and there are in fact nuclear reactors that give evidence for the equation. So I believe strongly - I have great faith - that E = mc2, but I can’t say I know it for a fact. As regards the sentence " Now faith is the substance of things hoped for, the evidence of things not seen":
I have a hard time understanding that using the normal definition of those English words. "Faith" is not a substance, nor is it evidence. For that sentence to make sense you have to utilize a definition of those words contrary to the commonly understood meaning, and so I don’t understand it. When you say, Dave, that you know something not of an "earth bound perspective" and that the knowledge comes from God, the discussion becomes a bit circular. I am by definition "earth bound", and when you say that you know that there is a God because that knowledge comes from God, it doesn’t leave a lot of room for debate. ……………………………
"Luca, can you summarize what was contained in that article in a way that a 5th grader could understand? I need some type of foundation to start this quest."Sure, no problem, Bick. Piece of cake. The reason I cited the article is partly because it is so seemingly counterintuitive and beyond the conception of people like you and me. I’m not even sure Wabash could grasp it, other than saying the reason it’s so complicated is because Republicans screwed it up. You may already know the basic Big Bang idea (which, incidentally, originated from a Belgian Catholic priest/physicist, a fact which amuses me endlessly and which I never fail to mention to my militant atheist/materialist brethren), that some 13+ billion years ago time and energy originated from a singularity that held all the energy in existence. It exploded with a magnitude that defies description and all the energy in the universe was released simultaneously. One would expect that when that energy converted into mass, the gravitational pull of that mass would have recollapsed everything back into a singularity, but there was an unexplained "rapid expansion" of space that spread out the mass and energy of universe so rapidly that gravity could no longer exert enough pull to collapse it. And the universe continues to expand - albeit more slowly - and over time some energy collapsed into quarks and leptons and whatever and then into into hydrogen, which in turn collapsed into stars which ignited under gravitational pressure, creating an enormous number of nuclear furnaces which in turn generated all the other elements of the universe, which then formed galaxies, etc……. I think I have that much right. The obvious question that Dave and I would ask - "Well, where the hell did the singularity and all that energy come from?" remained unanswered and Hawking’s explanation was that it’s like asking where south is from the South pole, i.e., they simply did not exist prior to the Big Bang. Essentially, you have to dismiss the concept of cause and effect. Without sounding too simplistic, that’s not a terribly satisfying answer. I don’t understand the competing Hartle theory, even in concept. I think it indicates that the universe does not continuously expand and that at some point it recollapses on itself. I don’t know what the significance of that is supposed to be, but I think it rejects the idea of Hawkings "rapid expansion" shortly after the Big Bang. I think it also implies that the universe may eventually collapse on itself and that maybe there are a series of endlessly recurring Big Bangs, but I don’t know. Hartle’s initial abstract starts off with " The quantum state of a spatially closed universe can be described by a wave function which is a functional on the geometries of compact 3-manifolds and on the values of the matter fields on these manifolds.”
As Inspector Cluseau once said, “ Aha, now we are getting somewhere." You tell me WTF that all means and then we’ll both understand it. Ultimately, my point was that despite all these exotic theories I don't think they can ever explain where, when or how matter/energy came into existence, and that " We'll never know" how it all started………………………………Luca

How's that for irony...If I'm understanding correctly, you have to dismiss the concept of cause and effect, for this to make any sense from a scientific perspective. This may sound incredibly sophomoric, but it seems the only plausible explanation that is consistent with basic beliefs, scientific or otherwise, is that God started it.
Now expansion of the universe is a concept I think I can get my head around. But I think I'll leave my faith based beliefs out of the scientific field for now.
