All thoughtful observers, but most especially the competent observer, should recognize the Universe's (and thus too, the universes') capacity for self-renewal.

But points do exist, of course,
In trying to discredit my suggestion that the contents of The Big Bang have a centre and an edge you have used two seriously flawed arguments as above. Not only this but you try just suggest it's my physics that's wrong with the statement as below.So if there is some tiny wattage per point
So, I feel entitled to highlight and scrutinise your methods of thinking, used in trying to discredit my ideas.Is this your position? Come back to physics.
This is a very important issue, so thanks for bringing it forward.In a previous thread, you said you believed in a creator.
In this thread you said you believe in teleology.
In many of your posts to us, you continuously ask for evidence or testability of any ideas put forward, Including our discussions about The Big Bang and the universe. Fair enough. Yet at the same time, you suggest the universe was created by a creator for which there is no evidence or testability. This doesn't seem consistent thinking to me.
Yes, I knew you would get it, but many might not. [This is why I quoted Einstein above. ]Also in this thread, you point out there's a difference between the physics method and the maths method. Previously, I was not really aware there was much of a distinction, so thank you for that.
Sorry, that wasn't my intent. I was probably rushing it. It's obvious that one can, mathematically, have an infinite no. of points in any line segment. I was trying to say there is a practical limit in the minimal length assigned to a line segment. Physics can only go down to the width of the Planck length, never to zero width, or rarely since lim->infinity can be a useful tool in physics and engineering, in some applications.As for your physics, you proposed that watts could be attributed to points, an even worse mistake IMO.
Please feel free to question my positions. If you discover I'm not mainstream, I would appreciate finding out about it.In view of the above, I don't have any confidence in your opinions anymore.
I always use science to address these questions, at least to what I understand of it. My personal opinions might make me lean one way or another, but if one is asking a scientific question, then only science can properly answer the question; religion and philosophy become hand-waving if they want to oppose the obvious science.My question to you is - which of the above methods of thinking did you use when trying to discredit my ideas about the Big Bang, mainly my proposition that the contents of the Big Bang have a centre and edge? This matters because each method will give a different answer.
More confusion here, you are using the word Universe with an uppercase U. The dictionary definition of 'Universe' is, 'everything that exists' so yes, of course, everything that exists may well be infinite and that, of course, can't have a centre. However, in order to avoid confusion, it's plain to see that I've been using the words 'contents of Big Bang' in all my discussions about the centre.The reason I discredit a center for the universe comes directly from GR (General Relativity). You won't have to look hard to see that GR is strongly opposed to any absolute center for the Universe. Space is fused with time and gravity reshapes this both broadly and regionally, which serves to eliminate an absolute center.
If you feel strongly it has a center, you're not arguing with me, but mainstream science (ie GR).
Yes, in fact, GR argues that a concentration of matter sitting in space will have a center (i.e. c.g.), just like our solar system has a barrycenter (c.g.).It doesn't seem to contradict GR to speak of a Galaxy as having a centre an edge and an inside and outside to it,...
The BBT cosmos -- if we wish to use this term since I agree it gets confusing what people mean by Universe in spite of Cat's efforts -- is distinctly different than chunks of matter sitting in a region of space.... so why can't the same be said of the contents of The Big Bang, I see no contradiction with GR here either.
It's nice to see statements that point-out that BBT does not include an actual singularity because, in science, the models must not extend to regions where the mathematical "wheels come off the cart". It's still amazing to me, however, that physicists can use the theory to shrink the BB cosmos into something very close to a singularity.1. The big bang started from a hot dense patch, NOT a singularity and so started with a finite size.
2. It's undergone finite rates of expansion
3. It has a finite age.
You may be right, but this is outside of science. We have no means to look outside our universe, even in principle. Something outside our universe will have to impact our universe in such a way that it becomes obvious. [M-Theory proposed some idea on this, which is the only thing that seems to present some way of getting a view that there is an outside, but all observations have been negative in finding the brane impacts.]If space consists of 'something', then the BB may well have created its own internal space, but at the same time, it must have existed in a pre-existing space.
Yet they don't for the reasons above. It's certainly easy to understand your argument, but physicists use the arguments from GR to disagree, else they would quickly want to be first to find a center and maybe get a Nobel prize.Anyone who believes the contents of The Big Bang are the whole universe must accept, by logic that, the whole universe has an inside and outside, a centre and edge.
So how big is it? What does outside look like? What is the shortest direction to get there? Such questions are meaningless, so far, in science. Maybe there is something beyond, but it's purely supposition.This is not to be confused with the observable universe, which is only a small part inside of the whole universe and so doesn't have an absolute centre or edge.
Why is it different? The Big Bang started with a hot dense patch of matter/energy sitting in a region of space and very soon after became a patch of matter sitting in a region of space.The BBT cosmos -- if we wish to use this term since I agree it gets confusing what people mean by Universe in spite of Cat's efforts -- is distinctly different than chunks of matter sitting in a region of space.
I still don't like the analogy of a balloon. Am I right in thinking that when you say a closed cosmos you mean it is not possible to escape from it? Can this be described without an analogy just by saying that if the contents of The Big Bang is an object containing mass then it has a lot of gravity, so much gravity that if you try to get out or move in a straight line you will just be pulled round in a circle all the time (around the centre of course ) is that right?But for the cosmos, in a closed BB cosmos, what happens when the same object is seen not only on your left but also your right, so to speak. If the cosmos bends on itself then each galaxy becomes like a dot on the surface of an expanding balloon. If one dot is red and the others are black, then if one goes clockwise to count all the black dots in one direction then what will happen is that eventually another red dot is found. But, and this is the key point, it's the original red dot. Hence it's impossible to pick an absolute center for the surface; any dot can be considered to be a center, but there can be no one special center for any dot.
The cosmos is the same story but in 4D (spacetime). Even if we could see all the galaxies and know their distances, by GR theory, we would see a homogenous universe where every galaxy is evenly spaced and, if one could look farther, eventually they would see their own galaxy due to the bending of light that comes with a closed universe. If you make this model cosmos flatter and flatter, only the distances get greater before you see your own galaxy.
You pose some interesting questions, I'm not setting out to answer them all, I'm not trying to say what is beyond The Big Bang only that at least there is just empty space. The main purpose of my proposing a finite size, a centre and edge are to change peoples thinking about The Big Bang, for example, many say that it is the beginning of all space and time and that it is 'everything that exists' and that there was nothing before it or anything beyond it. Everything that exists, exists in a space.You may be right, but this is outside of science. We have no means to look outside our universe, even in principle. Something outside our universe will have to impact our universe in such a way that it becomes obvious. [M-Theory proposed some idea on this, which is the only thing that seems to present some way of getting a view that there is an outside, but all observations have been negative in finding the brane impacts.]If space consists of 'something', then the BB may well have created its own internal space, but at the same time, it must have existed in a pre-existing space.
But remember also that matter bends spacetime, so unlike what is true in our galaxy (with a specific center), the BB cosmos, with all those galaxies, DE, and DM, bends so there is no direction one can take to get out. There is simply no way, even in principle, one can discover a geometric center, at least not within the purview of science.
So how big is it? What does outside look like? What is the shortest direction to get there? Such questions are meaningless, so far, in science. Maybe there is something beyond, but it's purely supposition.This is not to be confused with the observable universe, which is only a small part inside of the whole universe and so doesn't have an absolute centre or edge.
Yes, per BBT. But BBT, in accord with GR, doesn't argue that we are trapped in some sort of giant bubble that restricts us from going outside the bubble, but that spacetime itself can be seen as being all that there is, suggesting there is not distant spacetime beyond this model.Am I right in thinking that when you say a closed cosmos you mean it is not possible to escape from it?
That's a good question but in GR it's the shape of spacetime itself, not gravity, that brings one back to his or her starting place, at least in principle since that would be too long a trip. Of course, it's gravity that produces the shape of spacetime, but some may think that we just need more speed to get beyond some sort of escape velocity for the Universe, which isn't the case.Can this be described without an analogy just by saying that if the contents of The Big Bang is an object containing mass then it has a lot of gravity, so much gravity that if you try to get out or move in a straight line you will just be pulled round in a circle all the time (around the centre of course ) is that right?
If one holds that there must be a space-like structure that exists beyond what is confined to the BBT, then you are likely correct. I'm not saying this is wrong except to point-out that this is an ATM viewpoint. There seems to be no way possible, even in principle, in demonstrating spacetime itself is bundled into something like a ball. So, once again, such views are outside the purview of science. If you can suggest some means to test the supposition then you might have a useful argument. It will be cool if you can.So yes, you may be right, you might see our Galaxy reappearing if you keep going, or a light beam bending round and coming at you from the back and me not being able to escape to the outside, but that is still irrelevant as to whether the contents of the Big Bang is an object sitting in space with a centre and an edge.
If one assumes that there is something beyond spacetime, your arguments seem quite logical. Just understand that there is no reason to hold much value to such an assumption, at least within science.What you have said here does not discredit the logic of my three statements and the conclusion I drew from them, as in post 56.
Yes, and a BH is likely a good analogy, but with one condition -- nothing is falling into this BH. If nothing is coming into the BH, including gravity influences by orbiting matter, then any intelligence inside would conclude, erroneously, that there is nothing outside of it. This intelligence would be following the SM (Scientific Method) and understanding suppositions for stuff beyond are only suppositions.A black hole has some of the properties you are describing. If one is inside the event horizon, then when you travel you will always go round in a circle or will spiral inwards, and you also will not be able to escape from it but none of those properties detracts from the black hole and its surroundings being an object sitting in space. So why should it detract from the idea of the contents of The Big Bang being an object in space just because of these strange properties? Having a closed and warped interior is not incompatible with something being an object as well.
But they have no way to show objectively that something beyond is not there. They can't falsify your point of view, so, as I've said, you may be right. Claims that there is only the Big Bang or not aren't arguments for science, but for philosophy and religion. Until objective evidence can be presented that there is or isn't a beyond, then we aren't addressing such things within the purview of science.The main purpose of my proposing a finite size, a centre and edge are to change peoples thinking about The Big Bang, for example, many say that it is the beginning of all space and time and that it is 'everything that exists' and that there was nothing before it or anything beyond it. Everything that exists, exists in a space.
If there is a center, then there should be a scientific means to discover it because all the masses are in motion, so there should be some indication that there is a c.g. or something similar. No such evidence exists, at least for now, AFAIK.I agree it's not possible to discover a geometric centre or edge, I'm only arguing that there is one, again it's to change peoples thinking.
Suggesting something greater than BBT is not at all meaningless, especially within most religions. I favor this view, actually, but it's not a scientific view.I don't know the answer to these questions, if my proposition is correct then I don't think the questions are meaningless, currently, we can't answer them and may never be able to, but I think it's reasonable to ask them. I'm only saying that at the bare minimum there is at least empty space beyond The Big Bang. I don't see this as supposition it is logic and reasoning.
Yes.Once again, I don't yet see anything to invalidate my logic;
Big Bang starts with a finite size + finite expansion rates + finite age = finite size object now.
Yes, except when the object itself is all of spacetime. That's the difference. That's like saying we can go north from the north pole. There is no direction out of spacetime within BBT, scientifically speaking.Objects have an inside and outside, a centre and edge.
Yes that's a valid supposition. Syllogisms can be valid if the conclusion drawn is logically consistent based on the premises. But to be a "sound" syllogism, the premises must be true. A premise that uses space outside of spacetime can not be demonstrated as true. So you may have a valid argument but one cannot claim it is sound.At the bare minimum, I suggest that "everything that exists, exists in a space". The contents of the Big Bang being no exception.
This is flawed thinking from the beginning because it is just not possible to say what 'all that there is' is, it is completely illogical to say that 'all that there is' has a beginning with finite age and comes from something which had a finite-sized beginning because it wrongly assumes that 'all that there is' is a finite amount and not, possibly, an infinite amount. So, it's not possible to have a theory that offers an explanation as to the beginning or formation of 'all that there is' if it is not known and cannot be known what 'all that there is' is.spacetime itself can be seen as being all that there is, suggesting there is not distant spacetime beyond this model.
Because you can't have something from nothing, means there has always been something, so there is no beginning, only a phase change, transformation, regeneration, big bounce or recycling event. If space-time is a tangible something, then this too has always existed in one form or another.IOW, when the beginning happened so too did spacetime.
I suggest my logic is a little better than just imagination, at least it is founded on everything else in reality, ie everything that exists exists in a space, why make an exception for the big Bang without good reason?Perhaps it happened within some sort of space-like framework, but there doesn't seem to be anything other than our imaginations that can suggest it.
You make it sound like a complete and whole theory. I think something extra is needed. First, it doesn't offer much clarity at the start or turning point and second, you're still stuck with the absurd notion of indefinite expansion and heat death. Big gaps I think. So until these are addressed you can't say "what may or may not be outside of spacetime is superfluous", because it may have some influence on the workings within. For example, my (I don't know if its been suggested before) wild but not completely unreasonable thought that it is the gravity of what's beyond is pulling and expanding our Big Bang contents. In fact I would go as far as saying it is impossible to get a complete picture of reality until you do know what is beyond. I can't believe the contents of our big bang are totally isolated and just surrounded by an infinite void.GR and BBT argue that nothing extra is needed to make physics work.
A slight side track here before I continue.in GR it's the shape of spacetime itself,
Referring back to the top of this post, it is not valid to have a theory which purports to explain or to include 'all that there is' because 'all that there is' can't be known. It's just not possible to say that an object is all of space-time. It's worse logic than what I'm using. So in turn you can't be absolutely sure there is no way out of our Big Bang space time.Yes, except when the object itself is all of spacetime. That's the difference. That's like saying we can go north from the north pole. There is no direction out of spacetime within BBT, scientifically speaking.
I claim it is sound because it is based on the logic I've highlighted above. I think it is a bit better than just supposition, but I agree it still can't be demonstrated though.Yes that's a valid supposition. Syllogisms can be valid if the conclusion drawn is logically consistent based on the premises. But to be a "sound" syllogism, the premises must be true. A premise that uses space outside of spacetime can not be demonstrated as true. So you may have a valid argument but one cannot claim it is sound.
In everyday language, quantum fluctuations would be seen as completely random but since I don't believe there is such a thing as random then even quantum fluctuations will contain some order but it's a very disorganised order, in other words, it's very high entropy. If, say some of this disorganised entropy gets into your bloodstream yes it might age you very quicklyWhat if Entropy is just the side effect of Quantum fluctuations activity.?
Try standing in a room with high voltage static electricity and particles being created/destroyed as much as a billion times a second, bet you age quickly
Yeah not so good to stand in a room of static with random particles being created.In everyday language, quantum fluctuations would be seen as completely random but since I don't believe there is such a thing as random then even quantum fluctuations will contain some order but it's a very disorganised order, in other words, it's very high entropy. If, say some of this disorganised entropy gets into your bloodstream yes it might age you very quickly
When I need to vacuum the floor I sometimes find the thermal energy in my body cannot convert to mechanical work fast enough, so I don't like doing it. So now I can blame this high entropy or lack of ability to do work onto quantum fluctuations, great!!!.
On a slightly more serious side,)) I guess quantum fluctuations may have some kind of interaction with normal matter, so maybe some of its high entropy will rub off on ordinary matter.
I am not aware that a high voltage creates billions of particles a second, other than electrons, can you clarify that a bit more please. Yes I think you would age extremely quickly, I think it would be a good idea to call the undertaker before you throw the switch..
