In relation to the inflation hypothesis, what does our universe ‘exist in’?

I mean to ask, what exists outside of the universe(s)?

Is it an infinite dimensional Hilbert space?

General Relativity is constructed so that the space neither has to curve into nor expand into any space other than itself. Maybe you should study GR before asking questions like this.

There are no multiple univeres, and universe is the thing that encapsulates everything as a concept. There is nothing outside the universe and whatever you think is outside would be included inside the universe.

Space.
I think you just read the title of some popsci garbage and you were too lazy to actually read anything about it.

"Universe is expanding" is an oxymoron. Universe is infinite. So is the space. The matter inside is finite and it's been pulling apart from each other into the infinite space. Thats what they mean by expansion and thats where we look to see the redshift to confirm the expansion.

Ok I'm asking a question about an aspect or implication of a hypothetical model.

Hypotheses by definition do not have supporting evidence.

Inflation is the strongest competitor when it comes to hypotheses regarding the formation of our universe.

Ok, the basic idea is that a quantum energy density fluctuation allowed for energy to become 'trapped' in a particular region of space, which led to the creation of a false vacuum (which is tantamount to a well of potential energy), whereafter a quantum fluctuation led to a phase transition of sorts, which took the form of the Big Bang.

It could be thought of as analogous to water existing in liquid form in a subzero environment, which is referred to as a meta-stable state; an energy density fluctuation can then initiate a phase transition in which it turns to ice.

The laws of physics of our universe are thought to be determined by the nature of the quantum fluctuations that led to its creation.

In other universes, the laws could be entirely different.

What I am asking, is that in relation to this hypothetical model, what is the nature of the space that exists outside of our particular universe/region?

Is it infinite dimensional?

If you don't know enough about the hypothetical model, then that's fine but stop replying.

>> No.8257004

The thing is, spacetime and the shit it it is all an illusion created by your mind. Everything is forces and energy, and essentially intangible nothingness which due to our own nature, seems otherwise.

Consider a video game, there are rules and to the avatar in the game, those walls are effectively no different to the wall in front of you. But do those virtual walls exist? Does that virtual gravity hold you to the surface? Is it real or not?

Why can't you accept that everything is a story, and that some are useful to be believed, and some are not?

There is no difference between a hypothesis, theory, analogy, physical law, dogma, argument, fiction, moral, thought, or any object or word you can think of.

A story is a story; it is all the Narrative.

What does evidence have to do with anything? Evidence just makes the story useful, but doesn't make it any less of a story.

You can never see the universe. It is a story you put together.

You can never experience anything directly. If you could, then you wouldn't need the story.

The world is; it has no use of a story.
And you trick yourself into thinking the story is the world when you find the story useful to be believed, but that doesn't mean your story is the world.

Why don't you focus your argument on why your story is useful to be believed instead of wasting time trying to convince and persuade using the rhetorical trick of an appeal to the Platonic Fallacy by invoking what amounts to a religious argument of "God said so" by claiming your story is real because it works in this situation, for this perspective.

Inflation implies multiple universes.

These universes have their own physical laws and dimensions, i.e. four forces and 4D space time.

What is the space outside of these regions/universes hypothesised to be like?

Is it infinite dimensional?

If our universe is resultant of quantum energy density fluctuations in space leading to the creation of a false vacuum and hot big bang phase transition, then given an infinite amount of time there will be an infinite number of universes.

The physical laws that govern our universe and its dimensions were determined by the nature of the fluctuations that gave rise to our universe.

The pre-big bang space is considered to be infinite, which I have just remembered and therefore answered my own question.

Hi, OP.

To answer your question:

It is possible that the Hilbert space of a theory of quantum gravity may have an infinite number of dimensions, but not necessary.

For example, the Hartle–Hawking state is a proposed wave function of the Universe, which is calculated from Feynman's path integral.

It is a hypothetical vector in the Hilbert space that describes this wave function and it is a functional of the metric tensor defined at a (D − 1)-dimensional compact surface, the Universe, where D is the space-time dimension.

The precise form of the Hartle–Hawking state is the path integral over all D-dimensional geometries that have the required induced metric on their boundary.

According to the hypothesis, time diverged from three state dimensions after the Planck time and such a wave function of the Universe can be shown to satisfy the Wheeler–DeWitt equation.

Ignore the people in this thread that don't understand the picture, but you also need to forgot all the nonsense you think you know (i.e this >>8257117).
The universe doesn't need to be inside some larger space to expand - the expansion is just distanced between galaxies growing with time. Inflation was a period where expansion was very large (that's actually a lie - it has to do with the rate of change of expansion, but it caused very fast expansion in the past). Again, this doesn't require any larger space.

Your picture is suggestive of an alternative, called eternal inflation. This is where inflation doesn't stop, like it does in our standard cosmological models, but continues in most of the universe forever. Small pockets stop inflation and become like our universe, which in this model isn't the entire universe, just part of it - they call the whole universe the multiverse, and our non-inflating part the universe, but that's just terminology. The big universe is still 4D, just like in the usual model. Imagine an inflating balloon, that someone occasionally sprays glue on. The balloon keeps inflating forever, but these small patches get hit by the glue and stop inflating, instead expanding much more slowly as the glue sets.
Something like that ;)

How can the answer not exist?
Given that
1. Nothing exists outside the Universe 2. The Universe is Expanding (inflating)
3. The Universe has no "edge".
Then Shouldn't what we would intuitively think of as the edge, simply be the same point, such that the Universe wraps around?

You have a circle. The locus of points which make up the circle are collocated.

You have a sphere. The surface is all one point.

Does the Universe "wrap around"?

If I instantaneously project a line (ray) from the Earth, will said line arrive back here, from the opposite direction?

Shouldn't the answer be, OF COURSE!

The common analogy is a balloon or raisin bread.

The surface of the balloon is the universe
There is nothing that exists off the surface of the balloon.
There is nothing that exists in the region bounded by the balloons surface.

Only the surface exists.
In this sense, there is no center.

While it's true that the material of the balloon could be stretched out and a center be found, that has no equivalence in spacetime.

When we talk about the shape of the universe being curved, or locally flat, it's just a description of the constraints used, not relating to physical properties. This is similar to particle spin, as they are not actually spinning.

Also, the surface of the balloon is 2d. Spacetime is 3d, which causes us to imagine intuitively, a 4d embedding and other "space" that these objects occupy. Again, these notions should be disregarded as there is no need for this to be the case in solutions to GR.

Okay.
I am at a point on the surface of your balloon.
For the sake of argument, I am at the Equator on the Prime Meridian (it could be any point).
I walk in any direction.
I end up arriving back at the same point from the opposite direction.

Also. ANY point in the surface of the ballon can be considered the "center" of said surface.

The answer is "of course", right?

>> No.8258345

>>8258330
Technically no.
If you took a square piece of rubber, marked the center and then tied it together into a balloon, it would only have one center.

Your argument is that you can rotate the balloon so that this mark occupies any other point. This is true, assuming you have some axis of motion perpendicular to the surface.

Since spacetime isn't embedded in higher dimensions, your analogy doesn't hold because there's no need or way to demonstrate change in coordinates.

To your credit, if you marked multiple points on the balloon, expansion would from the perspective of each point originate from them.

But this doesnt mean each point is the same, or that each is a center.
The notion of a center has no relevance.

There's nothing to explain. You're the one making absurd claiming of some 'space' that doesn't exist.

The Universe is finite, and composed of the observable universe (what we can see) and that which is beyond. But remember the universe is finite, we don't know how large it is. Beyond the spacetime that we understand there is nothing. There is no 'outside of our universe' or 'space our universe is expanding into'. It just doesn't make sense.

Any astronomy/cosmology textbook would inform you about different geometries and what each one means. But anyway, here's some evidence. Its the Planck results from 2013 (WMAP did constrain the universe to a flat geometry, Planck just improved the constraints).

Be aware its a 66 page article, but here you go -

Well I think this is just a matter of definitions. The Universe is commonly (although not always) defined as something along the lines of 'all of time and space and its contents'. But what if there is more than space and time? Sounds pretty weird, but it wouldn't be the first time physics went against our everyday experiences (such as quantum mechanics). And if space and time appeared around 13.8 billion years ago but something caused them to appear, then whatever caused them to appear would be outside our universe -outside of space and time.

However some people define the universe as 'all that exists, or has existed, or ever will exist'. That's fair enough, if that's how they want to define it then who am I to argue. I'm guessing this is what you are talking about, so in that sense I would agree with you (although I am more inclined to use the word 'cosmos' instead of 'universe', thanks to watching Carl Sagan's Cosmos series when I was younger).

Ok fuck it...

The multiverse isn't a hypothesis, it's a prediction of certain hypothesis/theories.

For a hypothesis to be falsifiable, we do not need to be able to observe and test all of its predictions, merely at least one of them.

General relativity for example, predicts the detailed motion of Mercury around the sun, gravitational lensing and the gravitational slowing of clocks; however, it also predicts the spatial nature of the interior of black holes and what happens at their event horizons.

Inflation is now referred to as a theory, as it has made testable predictions, which this anon >>8257681 kindly pointed out earlier.

So it is a falsifiable theory that has supporting evidence, the eternal aspect of which will be confirmed to a much greater degree of accuracy if BICEP manages to detect the right sort of polarised radiation signal.

If you don't know what I'm referring to in that last paragraph, then you can google it.

Anyway, eternal inflation predicts what is referred to as the level II multiverse by some; this describes the region contained within our light cone (level I) and our region of non-inflationary space/universe.

Other theories that also predict a multiverse involve up to three, or even four levels.

For example, collapse-free quantum mechanics models and certain external reality hypotheses (fractal universe hypotheses, for example).

When it comes to falsifiable theories with supporting evidence, you either accept them as they are or go back to the drawing board and start again.

You can't say 'I like how general relativity predicts gravitational lensing, but not black holes so I'll omit those'; you either accept them, or come up with another equally viable mathematical model that is equally proficient at making predictions.

The same is true of eternal inflation.

I'm not home atm; I'll return later with a proper break down of inflation and its predictions.

What inflation hypothesis? There are many.

If Eternal Chaotic Inflation is true, and if our universe is not the "first," then our universe (our observable universe) exists inside a multi verse with many other universes. So there would be more space outside our own universe.

Infinite dimensional Hilbert space does not exist; it is merely a mathematical construct, so the question does not make sense, unless a sort of Platonism is presupposed, or taken in consideration.

Imaginary time is a like another direction in space, and it is perpendicular to real time, much like an imaginary number line is perpendicular to the real number line.

Well then it's a good thing my argument didn't relate to the existence of black holes:

The interior of a black hole cannot be observed directly or indirectly, but its nature is predicted by general relativity.

General relativity makes certain predictions about things that cannot be observed.

Eternal inflation does exactly the same thing and the multiverse is one of these predictions.

At first, we can agree, that predictions of other universes is mathematically sound and that, within the frames of inflation theory, the cosmology is logically consistent, right?

>Could I even falsify the beliefs about stuff "outside" of our universe?

So lets look at falsifiability:
>A statement is called falsifiable if it is possible to conceive of an observation or an argument which negates the statement in question.

So we are left with making observations/measurements of something outside our universe. Some people are saying this is currently not possible. I dont see where they are comming from, as our inability to interact with things that arent part of our universe, isnt barely anything to do with our technological shortcommings. As people already pointed out, we are totally disconnected from everything outside our universe.
It cant be falsified, other universes cant be observed at all. It is more metaphysics than anything. So the other anon was wrong with his idea about a falsifiable multiverse.
However, I strongly disagree with your notion of "completely made up stuff". Sounds a bit too harsh for me, since it actually can answer things about the fine tuning problem and is predicted by solid models

>> No.8261260

>>8261226
The analogy doesnt hold. Black holes can be observed indirectly. Things outside our universe cant. An unobservable prediction cant really be a point where a hypothesis can be falsified.

However, I disagree with your notion of disregarding a whole theory because some predictions are untestable. Inflation answered a lot of questions about our universe and is a steady changing theory as new measurements/experiments are made all the time.

>HOW CAN I FALSIFY THINGS OUTSIDE OUR UNIVERSE?

This might be a semantic problem at this point.

The inflationary model(s) is falsifiable, explains observations, makes accurate predictions and one of its predictions happens to be a multiverse

It makes certain predictions about unobservable things, just like general relativity does.

If you accept general relativity, then you accept the predicted spatial nature of the interior of black holes, even though you can never observe such a thing.

If you accept inflation, then you accept the multiverse even though you can never observe such a thing.

You can't cherry pick predictions.

But general relativity isnt falsifiable because of its predictions about the interior of black holes. Yes, the interior is in the same way speculative as the multiverse. But at least with black holes, we can study the effect surrounding it and can indeed use these observations to make educated guesses. With the "outside" of our universe, there is no interaction at all.

I'd say that at least 50% of this entire thread is me.

Everybody knows that most of the posts are OP. The one making the longest posts, investing the most time and getting mocked from all sides. Yeah, sure you showed us

I'm just bored bro.

Nobody actually talks about anything interesting on /sci/; it's just noobs, homework threads, career pissing contests and homework threads.

At least this thread was entertaining.

Actually, I received a string of counter arguments that lasted over 24 hours.

They were also combative and indicated frustration.

I had a great time.

There was actually some good discussion in here (well, for /sci/), so your intention and the fact that I dont believe you is irrelevant

>> No.8261420

No I am OP, damn it!

>> No.8261424

>>8261419

Well I enjoyed two days of counter arguments from frustrated anons, which I very much enjoyed.

You're disbelief is irrelevant to my enjoyment.

Im glad we all had fun.

I'd just like everyone to know that I posted this thread and then went to see my aunt in the hospital three states over.

I haven't been back online since then.

I have no idea who this maniac >>8261381 is, but he's not OP and if you look at all his posts he's clearly British as he's using British English

He's dominated the thread right from the beginning while pretending to be OP and I can't even begin to understand why.

This wasn't an epic lmao ruse thread, I just didn't understand inflation all that well.

My misunderstanding has been cleared up thanks to a number of anons in the thread, so thank you.
