From the fact that no given laws are adequate to describe the bb, why do you jump to the conclusion that no possible laws will ever be adequate? And why do you equate "an event without a visible cause" with "an event without a cause"? How can you be so sure that a cause will never be discovered?

If you argue that the universe did not come from something, and others argue that it did, the mere fact that they cannot decide between a range of possible scenarios does not invalidate their argument. Their argument stands or falls on their ability to justify the general "something from something" principle, not on their ability to pick a specific "something".

And I am not quite clear as to why one universe need be "equal in size" to another.

@ACB,
Im ready for anyone to make a proposal that would discount my thinking but none seem to be available for scrutiny. I have asked for the best proposal but got a meek reply about energy that spontaneously appears from nowhere, it appeared to support my thinking.

I would assume that this science demands that you can not loose energy, it only changes its expression. If that is the case you could not inherit part of one universe and leave a bit behind or it would be visible. Bits of universes left behind for us to observe?

Can you give me your views on why there is nothing observable before this universe, any idea would be good.

decay of subatomic particles are said to be uncaused. The reason is that there is a deterministic equation that govern the probability distribution of the decay time, so that at no point could we say it way decay at a particular time, but there is a high probability of it decay at a particular time.

Well, according to some theory, the universe that split off go into a different dimension, and that is why we don` t see it.

Maybe there is something observable before this universe, but we haven't been able to reach this point in discovery. First off, you need to ask yourself what YOU think the universe is. Is it finite, does it bend like a saddle turned upside down, or flat and infinite. Nothing from before can be observable in this universe(to our knowledge) unless its just empty space. You are created with in this balloon with everything else, you cant see anything on the outside until you pop through it. Thats the best I got, If I go any further my brain will start hurting.

Support your thinking? No. If you want to say science support your reasoning, then show me exact what the theory say. You can` t just say " it seems to". It "seems that" i am bill gate, but i am not.

Well, I am not an expert, but you may wish to consider the following:

1. There was never "nothing". According to QM (a well-tested theory with no known exceptions), there must have been a wavefunction before the bb (see vectorcube's post #44). And whatever one thinks a wavefunction actually is, it must be something. The fact that it is difficult to visualize does not make it equivalent to nothing. So the "something, then nothing, then something" problem does not arise; there is no break in the "something".

2. If part of a previous universe was left behind, why should it necessarily be visible? There are many invisible parts of our present universe (e.g. dark matter, black holes) that are only known indirectly, by reasoning from other known facts plus mathematics and logic. Maybe relics from a previous universe will become visible in future with more advanced technology.

3. But in any case, how can one distinguish between a bit of a previous universe and that which is "native" to our universe? How would the former be detected? Would it have some kind of "label", in the form of some peculiar property, e.g. the violation of some otherwise universal law such as the Second Law of Thermodynamics?

4. You are not going to get a firm scientific proposal as to what caused the bb, because no-one currently has the faintest idea which (if any) of several suggestions is correct. But that does not disprove the idea that the bb had a cause.

Laws of physics began at the Planck time? How did that happen?

Answer: They are applicable at time intervals greater than the Planck time and they can explain events after 10 to the minus 43 seconds. They are not applicable at time intervals shorter than the Planck time. The laws of physics break down and can't be used beyond 10 to the minus 43 seconds. There is no minus 44 seconds -what happens is the singularity.

Are you sure it is infinite? Really? Do we use transfinite numbers or what?

Answer: There are a few books I'd recommend: John Gribbins "In Search of the Big Bang," Stephen Hawkings "A Brief History of Time," and there's another book which I've just let a friend borrow and I've forgotten the author's name but "A Natural History of the Universe," all speak about the singularity as a zero condition of spacetime with infinite density ... and it comes out of Einstein's General Theory of Relativity. I'm not a cosmologist of physicist, but I'll give them credit for knowing what they're talking about.

Sorry, but i did not call anyone stupid. I called an idea stupid. And yes, in philosophy, intuition is very important, and certain intuition is more important than anything.

Answer: The intuition that compels the deduction that all things have begun from a state approximating (not equaling) a total void is the intuition that begs the question regarding origin. There is no condition other beginning that does not beg the question.

I haven't presented my 'causal argument' which is a valid solution to Immanuel Kant, but it will be intended for members of this forum who show respect for the ideas of other members.

You say: Second off. No, you are not allow to move all the way back in the deduction because our physical theory breaks down. Get it?

I say: This is a philosophy forum. This thread is 'metaphysics.' Metaphysics can move all the way back. We're not in a physics forum here. Get it?


You say: Why? maybe because you never study anything beyond basic physics, but as you study more physics, you notice that even basic theories have their domain of applicability. I can have an equation that describes how the forces relates to the distence between masses, but the equation tell you to divide by zero onces you have the two mass touch. Our theory is beautiful, and predictive, but it is wrong, because in reality, nothing goes to infinity or else we all die.

I say: I thought you we're opposed to anyone using such big terms as 'infinity.' Now how do you get off? You have some 'infinity' credentials conferred on to you by some hairbrained physics professor?


You say: Sorry, but saying it is the "void" , "non-condition", or the "ultimate" does not make it less stupid. What you mean might be "there is no state of affair for time=0". Perhaps, you want to make it profound by giving it a fancy name, and by making it completely absurd to wow me. If so, then you really impress me with the absurd part.

I say: It's amazing you can be impressed by anything.

You say: Curious, but where does this coming out of "chaos" mean? What theory, equation do you use? Where did this idea come from?

I say: If the bb was not a chaotic state of materials moving at great speeds within a highly compressed ball of fire, then what was it? Ordered? I suppose to an extent, yes, it could be ordered.

You say: but an argument needs to be 1) valid, and 2) the premise need to be true.

You don` t have a deductive struture, so you don` t have 1 as far as i can tell.

You don ` t have 2, because all your premises are falses.

I say: I haven't presented my whole argument, so no need to tear it apart before you know anything.

You say: The universe started in planct time? No

I say: No, I didn't say it did.

You say: The bb is when things get to infinity? No

I say, No, I didn't say this either.

You say: The laws of physics began at some point ? no.

I say: Yes they did ... at the Planck time they begin to be applicable. Prior to the Planck time, they break down ... they're useless. Get it?

You say: The universe started in chaos? very "mystical", but no.

I say: There's a thing called 'chaos theory.' The people who hold to it would disagree with you better than I can.

You say: You are not even doing philosophy. You know why?

I say: Yes Great Master Teacher of Philosophy and All Things Good and Noble. Tell me Great Sir. Let me know. I'm so stupid and you're so Supremely Wise. Do tell Master.

You say: I read academic philosophy papers, and the style and rigor that is being put in is impressive. The modern era is dominated by philosophy in the analytic tradition, and focus on clear by precise thinking. I don` t see the rigor , or attention to detail reflected in your writing. In fact, you write like you know nothing about modern philosophy.


I say: Analytic philosophy sucks.

And: The modern era of philosophy has no use for metaphysics, and so I have no use for the modern tradition of philosophy which has abandoned speculative philosophy and metaphysics.

Which begs the questions: Never mind the bloody universe. Why the hell are you here?

I am not claiming that the universe came from a causal chain of some sort. I don ` t know this. I am telling you that the universe did not come from nothing. Why? Because "nothing" is the same as " there is no fact of the matter". This is clear enough for you?

I don` t have a proposal, and i have no intention to speculate on this matter. I am telling you that the bb did not come form nothing. That is all.

No, this is not what you say. You said the law began at the planck time. For all that we know, there might be a law that described the bb at t=0. Obviously, we do not have such a law at the current time.

This is not what you say. You say the bb is a point with infinite density, and not infinity density as a consequence of some particular physical theory. There is a hugh difference! Our current theory might not be refined enough to explain the bb, so that is why we have these infinite value.

What the hell does "total void" even mean? Is that the same as "nothing"? Is there a mathematical description of this "total void"? I think not! Calling it a fancy name does not give it more weight.

First off, i am not insulting you in any way, but i think your idea suck. If you want to postulate some sort of mysterious "void" or "ultimate nothing", great. You do that, and i will tell you why it suck!


Quote:

No! You can` t say the bb is philosophy. It is part of science, and for all that we know, the bb might be explicable by physical laws.

To note: Modern metaphysics tend to be descriptive, and less speculative than you think.


Quote:

Infinity is often a sign that a physical theory breaks down.
My credentials? I am just a lowly Math&philosophy major that took alot of graduate courses in physics and math. I also read alot of textbooks for fun. Consider the kind of questions you have, i think i can tell you why you are wrong, or at least point you to articles, and textbooks on why i am right.

Again, this does not prove anything. There might be some other laws that govern the bb. You simply do not know at this point in time.

The real problem for me in accepting the big bang is that at the time of the big bang and the singularity gravity was infinite. Gravity and time are interconnected and according to Einstein time cannot move in a field of infinite gravity, but the enigma it did the problem is how?

Exactly the point i have made on several occassions Alan . The view of that singularity in real terms was that it was nothing. Nothing could escape no time no space, so if no space nor time could escape, it was nothing. I then ask what is nothing? everything could be nothing if it became everything. As you ask again, why did it appear at that moment ? if time commenced at that moment, then it has nothing to relate its time to, so its not a relevant question.

When we see something why can we not believe it? Every objection to my proposal is just as wild just as mysterious but because it takes its logic from observation it appears some how stupid.

Shostakovich;96807 wrote:
The question is a metaphysical one, though some might argue. I think where physics leaves off (the singularity) is where metaphysics begins (if we speak of a regression of events ... before the big bang). It may seem illogical to speak of an event before the big bang ... thought to be the beginning of time; but here is where I think critical thinking and philosophy are left as our only tools. There is no science, because science deals with observed, concrete realities. The singularity, or the condition/noncondition from which the bb was triggered, was a zero condition of spacetime, with infinite density. This begs the question: From where this infinite density?

Something else to think about: Evolution regresses to ever simpler and simpler forms, regressing backwards in time. The universe decreases to an ever smaller volume the further back in time we go.

So my best shot is this: The infinite density contained in zero spacetime regresses priori to the big bang to a less dense/intense mass through a series of expanding and contracting stages, all the way back to a point approximating most closely, nothing at all.

At least this falls in line with what we know: That is, that all things regress backwards to ever greater simplicity; so why not take this direction ... as pointed out by the evidence ... as far back as our reasoning allows and postulate that alll things began from a state approximating most closely, nothing at all.

This then begs the question: Is this state truly equivalent to a 'nothing' from which only 'nothing' follows?

I'd say no. It must amount to something more from which the series followed forward in time, towards greater and greater complexity.

What I think is lacking in so much of the argument back and forth in this thread is one noteworthy feature of our universe ... even evolutionary theory depends upon it ... and it is that this regression back in time towards greater simplicity is the most telling feature of all, and it needs to be taken into account when speaking of an ultimate beginning to the universe, for this regression to further and further simplicity points back to just that: an ultimate beginning ... in which space, time, mass, and everything else is condensed/regressed back to some ultimate indivisible, unified state.

One other factor to consider: Isn't it our own innate tendency to press the question of origin as far as possible? If we begin with some condition, concrete or otherwise, can we beg the question as to the origin of that condition? If so, then isn't this innate need to press the question further an indication that we haven't really begun at an ultimate beginning? Our need to press the question points us back to the same conclusion: That the universe began from some state that, were we to come to terms with it in our understanding, would not leave us begging the question.

It appears then that the most logical point from which the universe must have begun, is nothing, for nothing does not leave us begging the question: From where this nothing?

The question then becomes: How do we define nothing?

Immanuel Kant dismisses here, any appeal to what he calls 'the magic wand of so-called common sense.'

He calls for a critical exercise of reason.

So is it possible to give nothing a critical definition that goes beyond the ordinary/practical definition of nothing?

I think it is, because if we take away all that exists, we are left with a condition that can rationally be defined as an infinite, indivisible, boundless state, and hence, as an Absolute state.

It is not nothing ... but it is an Absolute ... that we must come to terms with in our thinking.

This incidentally, is exactly where Hegel begins in his philosophy and his attempt to answer Kant. I know of no other philosopher other than Hegel who begins with the Absolute, and at least, attempts to give it further definition.

I believe Hegel was on the right track here. I think it must be the Absolute that somehow gives rise to everything that now exists.

What we lack, is the understanding of that process.

Any arguments?


Have you a reference for Kant's phrase, "The magic wand of so-called common-sense"? I would appreciated it.

No physical quantity can be infinite, because the idea doesn't make sense. Infinity is not a specified quantity.

We simply don't know enough about the singularity to be able to jump to conclusions. We have no grounds for assuming that the current laws of the universe are the only laws there have ever been. Regarding the question of visible evidence of earlier states, see my post #67.
