And that kids, is what you call the infinite regress fallacy.This argument falls down when someone asks "Where did the "Thing that caused the first cause" come from?

Can virtual particles come to be without quantum fields?
No. This is not what I'm saying. This is something you introduced to what I said as your own analogy. You've made a strawman to rebut my argument.The point is that the surface of the earth is an analogy for the way general relativity treats space-time. Time doesn't 'flow' (there is no universal 'now', or any other universal moment of simultaneity, even in special relativity). Time is a direction (actually an observer dependant direction) through the manifold like south is a direction along the surface of the earth. Since there is no other concept of time that applies, the idea that it (the manifold) had a beginning (in the sense that the surface of the earth had a beginning because it is embedded in space-time) doesn't make sense.
I rest my case.Models that aim to describe the universe and physics during the Planck epoch are generally speculative and fall under the umbrella of "New Physics".
Ah good, since you aren't trying to show that the truth of the premises is unattainable; you are freed from your burden of proof. It also means that you haven't demonstrated the argument is unsound. There is, of course, no problem with you doubting the premises are true. Just understand that your doubt about the premises has no effect whatsoever on their truth value. Doubt does not constitute proof.I'm saying they are currently unknown and that we have very good reasons to doubt them (as myself and others have pointed out).
The evidence suggests a beginning 13.8 billion years ago. The lack of absolute scientific proof is perhaps why you reconsider your argument from science and instead consider the philosophical question presented in the OP.The premises are about the nature of the universe and causality, so in the domain of science, so you're never going to get absolute proof. What we do have is evidence that suggests they are, at best, highly questionable.
Okay, the universe is. You don't disagree with the implicit assumption of P2 that the universe is.The universe, as a spacetime manifold, 'just is'. It doesn't 'become' because time is part of the universe.
It matters, because the entire point of a very lengthy discussion now is to talk about causes. The question of movers is exactly what matters.What does it matter who is saying where to move? The point is that it is possible to move to open up a space, or even infinitely many spaces by the guests moving appropriately.
That the guests can move is obvious. How they move is clear. What you've failed to answer is why they move or don't move.What is the paradox? That the Hotel is full and that the guests can still move so as to open up a space? That is almost the defining property (according to Dirichlet) of being infinite.
You clearly accept that Mathematics must be Axiomatic and even say it is because of Infinite Regress of Explanation. I rest my case. We are done here.It's more than that. Either there is an infinite regress of explanations, or there is something that cannot be explained (or, technically, there is a loop of explanations).
I think it is a cool signature. I considered putting the Axiom of Infinity in my signature because it is just so cool...Yes, it is a closure property, not a 'building up' property. Closure under the successor function is one of the defining properties of the set of natural numbers.
Notice that in your definition above, there is no infinite process. The number 2, for example, is not seen in the definition. Only 0 (in the form of the empty set) appears. Also, the assumption is that there is such a set with these properties.
I would point out that without this axiom, the natural numbers can be 'built up' in the sense that every individual natural number can be constructed and shown to be a 'finite ordinal'. The axiom is about the existence of a set that contains all of these: a completed set all at once.
BTW: you might want to compare the axiom as you gave it to @ratiocinator's signature.
Putting infinite sets in one to one correspondence with proper subsets of themselves is well-known, but has little to do with what I had to say about the Hilbert Hotel. What I'm talking about are the movers of guests of the Hilbert Hotel.I am simply pointing out the basic properties of infinite sets. Like in the Hilbert Hotel, the paradoxes tend to be misunderstandings of how infinite sets differ from finite sets. One basic way is that they can be put into one-to-one correspondence with proper subsets of themselves.
What do you mean "Time may have a start"? And how does that differ from "the universe beginning"?It's more that in my view the universe doesn't begin. And that is because time itself is a property in the universe. Time may have a start, but that is not the same as the universe beginning.
Why would I think that all why questions have answers?What makes you think that all why questions have answers?
Yeah, this is not the analogy I made. @ratiocinator inserted this nonsense about the Northpole. It's a useful analogy in its own way... it just has nothing to do with what I was talking about.It is an *analogy*. In this, time corresponds to the latitude and the universe corresponds to the surface of the sphere. Longitude represents space.
So, time 'begins' at the South pole, space expands until the equator, then begins to contract. Finally, time ends at the North pole.
People are free to ask questions.The current expansion started 13.8 billion years ago. Whether it is even meaningful to talk about 'before' that is simply not known. Under most quantum theories of gravity, it is. Under general relativity, it is not.
At this point, it is an open question.
That the guests can move is obvious. How they move is clear. What you've failed to answer is why they move or don't move.
Anyway. You seem not to understand the significance of including the empty set. The empty set (zero) is the starting point for the natural numbers, not "infinity", not "negative infinity", but rather zero is the starting point to which successors are formed. The Axiom of Infinity allows them all to be in a set. This is very basic, basic understanding. Don't include the empty set and suddenly you can't find the natural numbers.
The significance of closure should've been clear to you. It is relevant first, to saying we have all the natural numbers and second to talking about the set of natural numbers as opposed to only talking about some of the natural numbers or talking about things which are not natural numbers. That's the relevance of closure here.
Putting infinite sets in one to one correspondence with proper subsets of themselves is well-known, but has little to do with what I had to say about the Hilbert Hotel. What I'm talking about are the movers of guests of the Hilbert Hotel.
What do you mean "Time may have a start"? And how does that differ from "the universe beginning"?
You are just fooling yourself. It's all a sham.They move to make space for other guests.
..and that is another sham. There is no such thing as "no time".The point is that causality requires time. If there is no *time* when the universe does not exist, there can be no causality of its existence.
No. This is not what I'm saying. This is something you introduced to what I said as your own analogy. You've made a strawman to rebut my argument.
I am talking about the Earth as a whole object that has a boundary (surface) which is not necessarily a single point in "time". I could just have easily decided to talk about your existence and defined your surface boundary (roughly corresponding to your skin) without assigning any sort of latitude or longitudinal system mapping your surface.
I rest my case.
Ah good, since you aren't trying to show that the truth of the premises is unattainable; you are freed from your burden of proof. It also means that you haven't demonstrated the argument is unsound. There is, of course, no problem with you doubting the premises are true. Just understand that your doubt about the premises has no effect whatsoever on their truth value. Doubt does not constitute proof.
Sorry, but I've no idea what you're trying to say, then. The space-time manifold (assuming that is ultimately the correct way to look at it) may be finite in one direction (the past). I simply do not see how you can look at the whole manifold and sensibly say that it had a beginning. It looks like you just haven't understood the analogy. A 2-dimensional surface, like that of a sphere, is a type of manifold, 4-dimensional space-time is also a manifold, which includes time itself as a coordinate. The whole thing is timeless, so it makes no sense to say it began to exist.
What case? The point is that we simply don't know what happened as we extrapolate further back because we run out of tested scientific theories that would be applicable, so we can't assume that time is finite in the past. It might be, but it might not be as well, we just don't know.
It's not me who is trying to prove anything. The argument in the OP is in the form of a deduction, which can only be sound if the premises are true. If we don't know they are true, and indeed have good reason to think otherwise, then the deduction has failed and we cannot rely on the conclusion.
Taking a set of unknowns, then making highly questionable assumptions about the answers to arrive at a conclusion that you want, isn't all that convincing.
You are just fooling yourself. It's all a sham.
..and that is another sham. There is no such thing as "no time".
Time is measured relative to something. It does not imply that time can cease.
..unless of course, you don't accept the concept of eternity.
Eternity does not presume the existence of matter.
It presumes nothing but being.
You were propagating quantum fluctuations are one of your main arguments, of course among others spelt out by others.
Thus, in this, I asked you if virtual particles can come into existence without quantum fields? Simple, basic question.
I'm not making an argument. It was a counterexample to your first premiss.
You've already had an answer: #1203. I'm not going to repeat what others have already said, and, to be honest, if you want to know more about quantum field theory, then you'll get more informed answers from @Polymath257 anyway.
Logically speaking, we have a counterexample to your first premiss but even if we accepted its truth, you then have a problem regardless in trying to apply what happens in the universe to the universe as a whole. Even if we accepted that everything within the universe was caused, then you still have to explain how you can have a cause without a universe - specifically without time.
So again, you cant answer, but are referring to someone else's answer, false or correct, you dont care, you just have been repeating other peoples arguments, propagating them as if they are your Gods with ultimate truths.
You are outsourcing intellect.
Mind you, your prophets and Gods answers in this thread you are worshiping are all false. So bad that its desperate, and too quickly googled, it is really really bad. But that is what you are worshiping. This is your religion. Worshiping other people.
Since you have not made any argument, this is an assertion to your "that guy said this so I believe it and propagate it" position. If you did make an argument, this would be ad hominem. But you never made any argument.
Do you even know how false the responses are? I mean seriously ignorant.
Try to use your own study and your own intellect, rather than outsourcing them.

As I have already stated, that is a ridiculous notion.Even if we accepted that everything within the universe was caused, then you still have to explain how you can have a cause without a universe - specifically without time.

We describe time relative to motion, and then you say that this implies that "time" can therefore "not be there" like mass.
It is purely a manipulation of concept, and nothing more.
Time is only measurable as in "relative to motion". It doesn't mean that time can disappear. It just "is". That is the meaning of eternity.
You can't suggest that eternity might terminate at the beginning or end of time. It is meaningless.
You've already had an answer: #1203. I'm not going to repeat
That's all we can do, I'm afraid.You are thinking in your mind..
And as I said, you need to drag your understanding out of the 19th century. The Newtonian idea that time is a constant backdrop to everything is known to be wrong. Space-time can distort (we have to take account of the fact to make the GPS system work) and, quite possibly have a start.
