    Infinity Paradox
AI Thread Summary
Infinity is a concept that describes something that goes on forever, and it is not a number. The discussion explores the paradox of whether an infinite universe can expand, with some arguing that spatial expansion does not contradict the idea of infinity. Brane theory is mentioned, with the assertion that branes are not sub-universes but rather mathematical constructs. The conversation highlights the distinction between mathematical and physical infinities, emphasizing that while mathematics allows for the manipulation of infinite sets, the physical universe operates under different constraints. Ultimately, the thread raises fundamental questions about the nature of infinity and its implications for understanding the universe.

I believe that the Universe is expanding. My previous post just refines ones view of what it means to "expand", according to Relativity.

clearing misunderstandings

"This is what drag, and others, keep saying, but I disagree. If someone speaks of the spatial dimensions themselves as expanding, then it doesn't follow that just some things could be getting farther apart, but all things should be getting farther apart. And if all things are getting farther apart, then this has to be happening throughout the entirety of space. Of course, there is not "entirety of space" in an infinite universe, which is why I don't think that everything can get farther away from everything else, in an infinite universe. Thus, the spatial dimensions cannot expand, in an infinite universe, IMCO (in my current opinion)".

no wonder you agree with me mentat.they were originally posted by you!they are quotes!thanks for calling me buddy,and THANK YOU for explaining to me how the universe could indeed have expanded faster than light during inflationary phase.you are my buddy too you know!:smile: let me state clearly what my views are:
1) mentat asked how could our universe expand as it is infinite
2) drag said a infinite universe can indeed expand.
3) i said the universe we study is NOT infinite.it CANNOT BE as it began at a big bang a finite time ago(10 billion?18 billion?estimates vary)but if an entity began expanding from a point a finite time ago at no later stage can it be infinite.it's common sense.
4) since universe we know is finite it can expand.CASE CLOSED.

majin vegeta you said models of an infinite universe made more sense.can you tell us briefly what these models are?thanks

Correction.
drag said that the point of the Universe
being finite/infinite is irrelevant here as
the thread deals with the possible paradox
of an expanding given infinite Universe. :wink:

it's common sense.
Had I been a sadistic human being I'd ask
you to precisely formalize the connection.
And even if you succeeded in this task I would
then ask you to prove that the type of "common
sense" you used is indeed absolute and
must "make sense".
I guess you should be glad I'm not a sadistic

What do you mean, sage made it pretty obvious: If something starts out finite, it will never reach infinity. This just has to do with the basic definition of infinity, which means "going on forever".

On the off chance that you still don't understand it, think of how long it would take a finite entity to reach infinity. Answer: forever. Since forever hasn't passed yet (and never will), the universe would never reach infinity.

And even if you succeeded in this task I would
then ask you to prove that the type of "common
sense" you used is indeed absolute and
must "make sense".

I'd say that it's not just "common" sense, it's definitive, and strikes at the very meaning of the words being used ("finite"; "infinite"; "expansion"; etc...).

Maybe it just became infinite - like an on/off

the derivative of the ratio between the volume
and the time) involved.

No, because that means that there was a time when it was not infinite. If there was a time when it wasn't infinite, it can never become infinite.

  • #110

I've seen this before, and it is a perfectly acceptable cosmological model, but doesn't answer the question of how the spatial dimensions themselves can expand, if the universe is already infinite. You see what I mean? While the model proposed in your link could be true, I wasn't questioning it, I was questioning the model of a universe (by which I mean the whole universe) that was small and became infinite.

Nothing is instantaneous, according to Relativity, so your on/off example is flawed from the start. Then you have the matter of the Universe's having been finite at some point in time. This also does not allow the Universe to (at any point, short of forever) reach infinite size.

.
look at the third question that majin asked.so drag let us leave the decision of what this thread is dealing with to him.not that i am saying that the universe could not be infinite.read on.
but before that let's clarify whether a finite quantity can expand to become an infinite one.consider the set of all positive integers.it's infinite.now consider the set{1}.it is a finite subset of the above infinite set with no. of elements being one.now say add other positive integers serially one after another in ascending order such that the set increases by n integers per second with n being finite.so when will the set become infinite?NEVER.or not until infinite time has elapsed.i can give more examples but the fact is iff the universe was finite at the time of the big bang it cannot be infinite today.this applies well to our observable universe which was just a point at the time of the bang.indeed hazzy's site gives it's actual radius.so what's the point?
now let us talk about the total universe.that's a red herring.you can't see it, observe it and there is no hope of observing it in future.what's the use thinking of something we can't even verify.but i must say the approach of physicists is rather pragmatic.they feel we live in an unbiased sample of the universe and whatever is true for the part we can see is true in general.research shows that our part is most probably flat.a flat surface extends to infinity.so they conclude the entire universe is a flat surface extending to infinity.if so by our previous conclusions it follows the universe as a whole must be infinite at the beggining of the big bang.since it has been expanding since(vide the idea that anything that holds here holds everywhere). so we come to the original question-can a infinite entity get bigger?
seen a thin rubber sheet?strech it-it elongates does it not?now assume a rubber sheet of the same material extending to infinity say along its length.mark 2 points on it by a sketch pen.now strech holding the sheet at these two points.surely the sheet will elongate(i.e. the dist. between the points increase)otherwise we will have to conclude that rubber has suddenly become as rigid as stone just because it extends to infinity.absurd is'nt it.verdict-infinite entities can expand and there is no logical fallacy in assuming that the universe, infinite at the time of the bang is expanding ever since.
i must say that any assumptions about the entire universe is purely hypothetical and will change constantly as more advanced theories come into being to explain newer facts about the observable universe which we are only beggining to probe in detail.anyway drag what does a switch has to do with the universe.enlighten me will you?

This is one of the assumptions that Science has already made (and everything in Theoretical Physics must conform to the assumptions of Science, obviously).

It's a good enough example, but irrelevant as a description of the Universe's expansion - as I've already shown.

about science in this unscientific hypothetical

Science makes no assumptions. Math is a language
and science uses it to discribe the Universe
(not with perfect success btw, whatever perfect
success might mean) if and when it works
better than other availible languages.

No. The Universe's expansion is irrelevant to
this example because this example has nothing
to do with expansion.

Don't answer this if you feel you have to,
answer it if you feel you can make a relevant
point, please. :wink:

That's not all I'm doing. I'm also reasoning with you on the nature of infinity. You continue to side-step my arguments, and it's rather frustrating to have to keep repeating them.

It's not. I do feel I have an obligation to defend my position, but if you would prove me wrong (which you don't seem to want to do, given your obvious side-stepping tendencies), I would give up that position.

Science makes no assumptions.

That is dead wrong. Science makes plenty of assumptions. For example: it assumes that there is an objective Universe, even thought this cannot be proven or falsified. This is just one example, but it should serve to prove that Science makes assumptions.

No. The Universe's expansion is irrelevant to
this example because this example has nothing
to do with expansion.

Yes it does. If something was smaller, and then was bigger, it got from smaller to bigger. If it did so, then it expanded, because "expansion" means "getting bigger".

Don't answer this if you feel you have to,
answer it if you feel you can make a relevant
point, please. :wink:
Thanks !

I like to believe that all of my points have been relevant, but, even if they haven't been, they have all had merit (as have all of yours), and should thus be considered directly, instead of being side-stepped.

You can understand from the above that there's

My reasonig system is that entities that are finite
CAN become infinite and the other way around.
This is done in a procedure I'll call - "metafinity".

Yes there is basis, the nature of the term "infinity". It would take an infinite amount of time to reach infinite size, if you started out finite. This is just a result of using the term "infinite".

This is not a "reasoning system", it is an assumptions, without basis. You are speculating, instead of deferring to the already rigorously defined avenues that Science has been pursuing. IOW, you are presenting a speculation, without Scientific basis, and expecting it to solve a problem that scientists have been struggling with (in a scientific manner) for a very long time.

Exactly, it deals with observations, as though they actually existed outside of the mind of the "beholder". Remember, just because it seems like an obvious conclusion, doesn't mean that it isn't an assumption (which cannot be proven or falsified, btw).

Nope, it "metafinited". :wink:

Again, you attempt to solve a scientific problem through an unscientific approach (presenting your own speculation, and (in case you hadn't noticed) redefining the properties of "infinity").

Yes it does. If something was smaller, and then was bigger, it got from smaller to bigger. If it did so, then it expanded, because "expansion" means "getting bigger".
Expansion isn't necessarily getting bigger. Take a sugar cube, one piece. Crush it - many pieces. Expansion. Number of distinguishable pieces expands. Think entropy, varing timeflow, evaporation into vacuum, you can get to possible illusion of spatial expansion.

so the point is if the universe is infinite today it had to be infinite at the time of the big bang due to the constraints of physics.metafinity did not happen after the big bang and we are not concerned with what happened before.

Yes, the particles "expand" away from each other, is that what you mean?

If so, then your reasoning only works when "expansion" means "getting farther apart". However, the Big Bang theory (when coupled with General Relativity) dictates that the spatial dimensions themselves, are "getting bigger" (expanding).

Yes. Number of distinguishable spacetime positions IS 'spacial dimensions themselves'. Particles come only after that. If given particle 'fills' fixed number of spatial positions, it will not 'expand' with space. Purely my opinion. Entropy increases with number of possible states, so I speculate it has to do with it even though particles remain intact.

That's why it makes sense - because "bases",

I did not and will not provide a basis by not
defining the word sense. Observation is just
something - whatever, the rest is assumptions

It would take an infinite amount of time to reach

a result of using the term "infinite".
Since niether the finite nor the infinite presents
even partial solutions to the mystery of their existence
I see no reason to consider any solution as absolute,
beyond the likely preferences infered from observation.
If you wish to deal with absolute reasoning
please refer to the God & Religion forum. :wink:

And what was that scientific problem, Mentat ?

Sage, our current cosmology models are patheticly
primitive in terms of really providing some answers.
It indeed seems likely according to modern physics
that the Universe could not just become infinite
but science can only state likeliness, it can't
prove things beyond any doubt.

Also again, read my lips - SCIENCE MAKES NO ASSIMPTIONS.
I don't know of what's an "outside reality". Physics
deals with measurements of space and time but it
does not have a parameter called "outside reality"
nor does it have a numeric value for such a parameter. :wink:
Clear ?

"...However, I'm talking about space itself. If you take a space that is infinite (as in, having no end), how could you possibly add more space to this?... "

This may have already been mentioned in this thread -- but an answer to the above would be:

To 'add' more space to space, you get rid of all of the junk that is taking up space within the infinite.

Say like, the Earth, dissolves and the area where solid mass exists -- becomes added space.
 
  • #140
It comes from a childs joke; "How many sides to a Circle?"

The answer is "Two, inside and outside."

From that we define 'space', and that is by delineation.

The definition of "infinite" is 'undelineated space', or "Space with no boundries", but this brings us to a simply problem.

All of the thoughts in our heads are 'delineations of space', hence we can conclude that an 'undelineated space', a 'space without boundaries', is something that we cannot conceive of.

Ergo, no thoughts on the subject, no math, no concepts that will "fill the intellectual bill" as there cannot be, because every thought, is a "delineation" of space.

Thanks.....have nice thoughts!

something - whatever, the rest is assumptions
and likely patterns.

How is it that you make an assumption about the basis of my assumption, while at the same time denouncing that such a basis can ever exist?

Since niether the finite nor the infinite presents
even partial solutions to the mystery of their existence
I see no reason to consider any solution as absolute,
beyond the likely preferences infered from observation.

There is one thing that is absolute about finity and infinity: their definitions. They are rather clearly defined (as far as words go) and should thus only be referred to in a way that honors their meaning (otherwise, you could just as easily be discussing some entirely unrelated term).

I'm not trying to solve anything and nor am I
presenting any scientific basis. I'm just making
a hypothetical assumption because this thread
has made it enitially already and then went on
to discuss the possibilities of expansion in
such a case.

Actually, your idea is not an hypothecical assumption, as hypotheses can be tested.

BTW, this IS a reasoning system just
like any other. It just doesn't appear to apply to
observation, for now.

Then it is not science, and should restrict itself from scientific forums.

We just have observed data, "outside" makes no
scientific sense in addition to what's observed.

I don't understand this, what do you mean?

And what was that scientific problem, Mentat ?

I thought it was the expansion of the Universe (or, at least, whether the Universe can be finite and yet expanding).

Also again, read my lips - SCIENCE MAKES NO ASSIMPTIONS.

If Science makes not assumptions, then it should be perfectly comfortable with someone's saying that there is nothing but a singular Mind, and that we just percieve there being an objective reality. As it is, Science is not comfortable with this assumption, and must thus be making an assumption to the contrary.

I don't know of what's an "outside reality". Physics
deals with measurements of space and time but it
does not have a parameter called "outside reality"
nor does it have a numeric value for such a parameter. :wink:

"Outside reality" refers to that which does not exist abstracly, in one's mind, but rather has physical/tangible existence.

I'm loosing the thread of thought here.
In general, observation as I meant it is not something
that has a strict definition. It's just everything = existence.

O.K. But, the strict defintion is in no way a
justification of your absolute reasoning, so I do
not see how that helps you to prove your baseless
assumption about the inability of the finite to
become infinite or the other way around.

(You see the difference in our approaches to

btw, in most cases you still keep arguing to

attitude if you ask me. :wink:
Anyway, I just make probabalistic assumptions and
again if you disagree with them the burden of

Now, this is NOT a way to "win" arguments. I really
don't care if I end up looking like a complete
idiot , sometimes...:wink:
This is just the way that appears to be the most
basic in argument construction or indeed in
reasoning - the Antrophic principle. Again, even
that may be shown probabalisticly wrong in the future,
but today and throughout human history it's been
pretty reliable...:wink:)

The only and main way that science can expand in addition
to new types of observation is new reasoning systems
applied to it, that is the source of all current
scientific theories - to find the most consistent
perspective.

Scientificly that term makes no sense. Physics
uses the concept of distance that is a parmeter
applied to a certain type of observation data.
But, except saying that that piece of observation
data is inconsistent according to our applied reasoning,
which is clearly not the case, there is apparently
nothing more that one can accuse science of here.

WHO SAID IT'S NOT COMFORTABLE WITH THAT ASSUMPTION ?
Science makes no true/false judgement on this
point at all because there is no acceptable
reasoning for now that makes us view at least
some observation data as relevant to this point at all.

If you remember what I said to LG FGNF(may he find a
good new forum ) many times it was that there
appears to be, for now at least, no evidence to
either support or not support his hypothesys which
is why it's simply an unneccessary assumption.

Do not confuse this with the reason he was banned. :wink:
The reason he was banned was connected to the fact
that he did try to present such "evidence" by
twisting science (sometimes in interesting, but most
times in rather clumsy ways resulting from his
relative poor knowledge of it) and by not really listening
to people trying to correct him, thus creating some
misleading threads with misleading subjects which
had the potential of misguiding the perspectives
of other members. (Still, though neccessary, it's ashame he was banned...:frown:)

Does Science (and in the remote case that after reading

an explanation :wink:) ?

Peace and long life.

What are you talking about? Infinity's strict definition is that it goes on forever. Part of finity's strict definition is that it does not go one forever. Thus, they are incompatible. One cannot ever become the other. They are of a qualitatively different order.

O.K. Mind proving the inability of proof for my

I already told you, it defies the definitions of the words that it makes use of (finity and infinity).

No, I don't think that I can win or lose this argument, but I do think that your reasoning (on some of these points) is flawed, and so I respond.

Anyway, I just make probabalistic assumptions and
again if you disagree with them the burden of
proof of their impossibility is upon you.

Thus, yours is not a scientific method, as probablistic assumptions, that may or may not even be provable, are not in the realm of science.

This is untrue. The Scientific method is one reasoning system, an cannot have other reasoning systems applied to it.

uses the concept of distance that is a parmeter

but except saying that that piece of observation

which is clearly not the case, there is no more
meaning that "outside" receives in science.

While Physics has shown that there is no relevance to saying that one thing is "outside" of another, the other Sciences make full use of this concept.

infinite Universe in the first place. So my assumption
may be considered unscientific, but then wouldn't

No, there is nothing wrong with an infinite Universe. The problem arrises in trying to say that it wasn't infinite, but became infinite.

Science makes a distinction between the mind of a human observer and that which is observed (othewise the Scientific method would become completely invalid).

There is indeed a problem from the perspective of modern

all of science.

First of all, in general the concept of an independent
observer has been abandoned by science almost a century
ago, better get uptodate. :wink:

Second, there is no scientific distinction between
the "mind of a human observer" and any other group
of molecules (except their types and formations) and
so it will remain until shown to likely be otherwise
through some scientificly relevant evidence.

Doubt or shout !

No, I think it is you who doesn't understand the Scientific Method. It starts with observation, then the one collects data, then one hypothesises, then one rigorously tests the hypothesis, and then (if the hypothesis happened to survive testing) one has formulated a theory. Science is based on theories and observations, not on wild assumptions of "what if".

The same as the previous response.

How so? The Scientific Method (as I have shown above) is one reasoning system. If you add other reasoning systems, then you have left the realm of the Scientific method.

Alright, an example: Neurology. Neurology give a distinction between that which the mind observes, and that which is observed.

No, it's not just a scientific problem, it is a problem of definition. (See above).

It was abandoned by subatomic physics, nothing more. I have some knowledge of subatomic physics (whether you wish to acknowledge that or not), but I also have knowledge of other branches of science, and they still make the distinction on an everyday basis.

Infinity itsself is a paradoxical notion that we give to concepts that we cannot yet fathom due to limitations on science, or the limits of our minds. Infinity cannot be proven, as there is no solution to the problem. Therefore since infinity represents a problem with no concievable solution, it can never be definitively solved. Take PI for example. As of yet no known solution (last I heard was to the 10 billionth decimal place). So we assume it's infinite because the solution is perhaps beyond our minds to comprehend. But we'll keep trying, and we may keep calculating and never reach the end, so the infity of the problem will remain an unsolved issue.

Such is the nature of the universe. We say that it's infinite, but it is only a theory. Can we prove the universe is infinite? No. If it is indeed infinite, then we will never reach the end, and thus the theory remains so, whereas with finite measurement, we may be able to one day in a distance unconcieved future reach the end of a finite universe. Perhaps one day we will one day develop the capacity to travel billions of light years to the other side of the "known" universe, only to discover that we've barely moved in the scope of things. Perhaps the universe is finite, and 1 trillion light years distance is merely .0000000000001 percent of the distance to the edge. It could be that the universe is finite, but as yet it's impossible for us to comprehend the size of it. It's all about perception, and I know we are still but mere children in our understanding of the universe.

Zantra, I'd just like to correct you by mentioning
the fact that math is an absolute abstract (thought out/
invented) system and that [pi] IS proven to be irrational
by an appropriate mathematical theorem. Thus, it will
never end.

It's a hypothetical process I proposed, remember ? :wink:
If I knew how it is done it would be more than
just hypothetical. Now, don't try to play reverse
psychology on me cause if you say something's
impossible you're the one who has to prove it.

The scientific method is not a reasoning system.
The scientific method uses reasoning systems.
All scientific theories are formulated by applying
reasoning of some sort to observed data.

For example, If I reason that everything has a source
then I can say that this orange is the product of
some other physicly defined entity. If I reason
that everything appears out of thin air then
I can say that this orange just materialized.
Of course, observation and the reasoning applied
to it and accepted as scientific are mutualy
connected. We draw our reasoning principles from
observation and we apply them to observation.

Another example - I consider everything that is
mathematicly consistent and appears to discribe
observation to be science. This approach is based
upon the reasoning that math applies to observation.
This in turn has it's source in the fact that it
appears to us that most observation data includes
some basic common principles that we summed up in
the form of mathematics.
Originally posted by Mentat

I don't think I understand the relevance here.

The distinction you're making is a distinction within
observation. But, for something to really be "outside"
one needs to prove that something exists that is
independent of observation (which I personally think
is probably impossible because I think that existence
and observation are most likely inseprable synonyms in
this respect).

That's because they do not really know how to do without it,
for now at least. The most fundumental principles
of our reasoning are separate entities, empty space
and more. Further more, the issue becomes much
less of a problem at macroscopic scales. So, approximations
do fine for the most part aspecially considering that
all macroscopic scale sciences are still full of these.

Live long and prosper.

.

Ok you say it's been mathmatically proven that there is no end to PI. Show me. YOu can't. We make the "assumption" that it's a neverending loop because we cannot calculate an absolute value. It's again, a "theory"

PI is a bad example, so let's try a different angle. We used to believe the world was flat and that eventually if you reached the end you'd just fall off. We didn't "KNOW" it was, but society made this assumption based on their limited knowledge of the world around them. Then columbus proved them wrong. It's the same scenario. Making assumptions based on limited date to hypothesize, but again we come to the word "theory" which is not proven. To put it in the most basic terms. The Earth is round. I can travel along an axis and eventually I come back to the same point, thus the observation is proven correct. Prove to me with unrefuteable data or conclusive proof that the universe is infinite. And that, is simply my point.

Infinity is a self-defeating paradox that cannot be proven because the very nature of the concept represents a lack of proof or definition.

Purhaps you misunderstood me. I agree with you
in general about REAL infinity. However, when
it comes to math which is a strict and defined
system that we invented - it is capable of proving
something within it is infinite.

Here's the theorem and related links if you wan'em:
