Is the universe eternal?

Is it plausible to believe that there is only one 'universe' that has always existed?

I know that science agrees that, as per this analogy for existence, 'an infinite number of monkeys hammering away at infinite typewriters for an infinite amount of time will produce the entire works of shakespeare'.
Does that not mean that if you give the universe infinite amount of time, you are likely to re-exist?

>> No.4979494

i've always wondered whether the universe is part of something bigger. like how we once thought that the earth was everything until we discovered that it was only a small part of the universe. why do we assume that the universe is now everything? it has to expand into something.

sorry about my conjecture, op. i like the questions, got my brain churning

>> No.4979498

Is OPs image accurate?

>> No.4979510

I don't think the current structure of the universe is eternal. But the 'energy' that makes everything around us can't just disappear and reappear out of nowhere. It must have always existed.
If it can disappear, where does it disappear to or into?
If it can reappear, where does it reappear from?
The only logical explanation is that it has ALWAYS been there and will ALWAYS continue to be there. Maybe not eternally in the current structure of the universe, but that 'energy' will always be around.

That 'energy' is what makes you, that computer, that keyboard, those rice crispy squares in your hand and that mug of tea beside you.

It's absolutely mindblowing.

>> No.4979514

.If you believe the following two statements are true:

1) a civilization sufficiently advanced would be able to create simulated realities

2) such a civilization would create many simulated realities for study, entertainment, etcetera

Then is it more likely that we are one of the true realities, or that we are one of the countless simulated realities that a true reality would run?

There is circumstancial evidence of our universe being a simulation. In quantum mechanics, particles exist as waves of probability, in every possible state at once, until an "observer" collapses the probability wave and forces it to behave like a discrete object.

Why would the universe be built that way? Well if the computer running our simulation isn't powerful enough to track every quantum state, it can probably get by with approximating most of them, and only really tracking the ones people are looking at.

Why would our universe have a built in speed limit, making it impossible for humans to explore the rest of the cosmos? Why do we appear to be alone in the universe, when everything we know about how humans supposedly came to be says that, given the sheer number of alleged stars and planets out there, life should be all over the place?

the cold reality is, we are alone in this universe, there is no other life, other galaxies probably dont even exist as more than paintings on the sky, and the speed limit was put into place to make sure we can never find that out.

We're a simulation.

How does this affect us? Well, not much I guess. Doesn't change anything about how we live our lives.

I value your post and opinion. I can see the logic that blatantly arises from it. But there are a few points I, personally, disagree with but will not have the audacity to say they are false.

>2) such a civilization would create many simulated realities for study, entertainment, etcetera
Then why give us an expiration date? Why go through the unnecessary process of evolution to get us to this stage?

>Why do we appear to be alone in the universe, when everything we know about how humans supposedly came to be says that, given the sheer number of alleged stars and planets out there, life should be all over the place?

I don't think there have been any statements of us being 'alone'. We haven't even traversed a percentage of the universe yet to make these kind of statements.

>How does this affect us? Well, not much I guess. Doesn't change anything about how we live our lives.
I don't think anything really does. The idea of a simulation is definitely a curious thought, nonetheless. I agree with this statement.

Also, you have to consider that 'existence' is an incredibly unlikely phenomena. To have you, sitting there responding to me has absolutely gone against all odds and chances.

I for one dont believe that the big bang was an occurrence.
I personally believe the big bang is actually an ongoing process of matter being spit into our universe.

I like to believe that the center of our universe is the tail end of an ultra massive black hole, one that makes the star producing black holes at the center of galaxy's look like a speck of dust in sheer size comparison.

>> No.4979558

>>4979553
As I said, give the universe an infinite amount of time and we become inevitable. As does our 're-existence'.

If an infinite amount of time is not afforded to our universe, you can then see our unlikely our existence is.

Now, a better question is - why has the potential for our existence been so firmly ingrained into the universe?
Look at it this way: You can have an infinite number of monkeys hammering away at an infinite number of typwriters for an infinite period of time and, sure, they will recreate the works of shakespeare - but they will NOT create the universe. Why? Because the potential for them to do so is not afforded. Without a typewriter they cannot reproduce the works of Shakespeare now, can they?

So I think that's a more pressing question.

And I, personally, am agnostic.

>> No.4979562

>>4979510
I also believe that whatever makes up god and his reality is not bound by time and space, and thus is an everlasting existence that always been there, and is in fact composed of energy.
There can be no such thing as getting born and dying outside of our universe, cause if everything had a beginning, we could not even exist.
Because then there would have been a point where nothing existed, and the very first being had to be produced from nothing.
That is fundamentally impossible, no matter what perspective you unleash on it. (except those who believe in fairy tales).

God may very well have created our universe to produce more energy, as moving matter leads to new forms of energy, and more energy comes out of it then was needed to create it.

So IMHO, the universe is a huge energy producing facility, that at the same time acts as a learning school for young souls.

Personally i think its still impossible, take a computer that capable of processing the universe, and let it process random bits, how big are the odds it will eventually create a perfect universe as we perceive it.

Its too unlikely to be so without someone or something having written an algorithm that guarantees the existing condition of life.

Another point is that if you let the monkeys hammer away, they will eventually just create a bunch of loose words that can be conjoined into a Shakespeare, but they would never produce an actual work because someone would have to put the work together.
The monkeys would in fact go on forever, they would produce the required words, but it would never end up in the right order.

I am a creationist btw.

>> No.4979572

>>4979566
Our awareness, the more we age, the more clear things become to us, this is a direct result of experiences we go trough in life.

I believe our awareness is natural occurrence that happens beyond our universe, and we get born simply to train it.
Otherwise, what is the point of learning if you die anyway.

>> No.4979575

>>4979570
> I am a creationist
That's fine. Most of this board will instantly mock you but I, personally, see nothing wrong with this. So long as you are not willing to profess with absolute affirmation that God does exist. If that is so, then there is no point conversing as neither of us will walk away learning something.

In any case, the analogy with the monkeys is that if you give them an infinite amount of time, they will inevitably produce every possibility with their typewriters that will, eventually, produce the complete works of shakespeare - all in order.

That makes complete logical sense. Now, the real questions are:-
1. Is our universe eternal?
2. Why does it have the potential to establish an 'existence' of some sort.

An infinite number of monkeys on typewriters may produce the works of Shakespeare - but they will not create a universe. Why? Well, look at it this way. If you didn't give those monkeys a typewriter they would not have the potential to produce the works of Shakespeare.
Why does the universe have the potential to create life? That's the more pressing question. Questions of 'why', however, cannot be answered by science.
That's where philosophy steps in.

>> No.4979583

>>4979575
Actually, from my creationist point of view, god has to exist.
Or at least an existence that is not bound by time/space.

Otherwise there would have to be a point of origin where nothing existed, and suddenly something came into existence from nothing.
This is impossible from a scientific point of view, so there has to be something more and bigger.

If that would be true, then the universe would be our god.
The sole definition of a god is simply what you make of it, but always something/someone that is responsible for the motion of existence as we know it.

But how do you explain then that our universe exists in the first place?
There has to be something that could have existed forever, but it simply cannot be bound by time/space, because everything bound by it degrades and dies.

Yes, but our universe also contains matter, if our universe would expand solely on energy, then matter was never needed in the first place.
I do believe however that there is a universe composed of energy only, what i like to think of as real existence.

Because our current existence is what we perceive as true existence because we know nothing beyond it.
If our universe is indeed all there is, then perhaps the Buddhists got it right, and we do reincarnate.

However from my perspective its absolutely useless to let a soul/person got trough an infinite cycle of having to reinvent the same wheel.

To me everything in the universe got an ultimate goal, even the smallest things, reincarnation defeats the purpose of such a goal.

Now to be on topic, i also try to join all existing points of views on what we and our universe really are, and where it comes from.

I think every perspective holds a form of truth, and they are all fueled by the desire to know more.
Even religion holds many truths, religion is simply a really old philosophy done by people (prophets) with a greater understanding then the people around them.

I think all perspectives that exist simply do because we are connected to whatever created us, in ways that we cannot perceive or explain.

That our awareness is indeed projected into a virtual existence, and that our brains are actually the only thing that generate the universe around us as we perceive it.

Right, i believe "nothing" is actually something, its not fundamental to claim something comes from nothing.

Because try to think about what nothing really is, its nothing, its a state that cannot exist, because it it could, we would not exist.

Nothing is an everlasting state in which actually nothing ever happens.
If something can happen in it, its not nothing, then theres still something that becomes more.

The problem with your shitty reasoning is that we have explained all the shit already. There is no more mystery there. We can actually predict when the energy will disappear and what/when it will return, and explain it in great fucking detail. There are entire libraries on the fucking subject, and thousands of fucking labs to observe that shit.

It is the way the universe operates, and it is understood very very very very very very very well already. All that shit was already discovered and debated over 80 fucking years ago.

The problem is you have a very shitty and limited understanding of how the universe works. You really haven't observed shit, as you aren't exposed to shit. What the fuck do you actually know about the universe? You know how a very few select human-scale electromagnetic systems work, if fucking anything.

You know nothing of bigger or smaller scales, you know nothing of the other forces in the universe, and you no absolute fuck-all about how the forces of the universe arise from more fundamental concepts.

Then, with your sever lack of fucking knowledge, with your very very very very limited understanding of only the end results of one force, you question....Why does the universe not adhere to my extremely limited observations and understandings?

Do you realize how fucking stupid you sound? The problem isn't just that you lack knowledge, it is that you don't even realize you lack knowledge. You lack so much fucking knowledge, that even your initial premise regarding the universe is fucking shit.

Your questions and whole fucking train of thought is akin to asking if a piece of fruit is happy, or if a table is married. You just fail all around. Your questions are just nonsensical.

Hardly, i simply wont believe they disappear until evidence is provided that goes further then a simple observation.

Its not grasping at all that any sensor we build can hardly grasp the universe around us.
We are not even able to detect whatever force is at play that we suspect to be dark matter.

Maybe dark matter is a missing link between energy and matter that makes us think that particles can disappear.
Theres just no evidence, only an observation, thats not enough to make a valid claim.

Both statements are true.
The uncertainty principle says that even zero energy has an uncertainty over a finite time. So an energy less than or equal to the uncertainty is indistinguishable from zero energy. That way the virtual particle can "borrow energy" from nothing but it has to give it back.

This has always been one of the most divisive issues in physics, and to a similar extent philosophy. Physics seems more focused on interpreting empirical data and developing universal models that accommodate and explain our observations than axiomatic definitions of logic. It Only strives to establish congruity between these different perceptions, usually by applying mathematical logic to them, hence David Mermen’s famous quote on the philosophical implications of Schrodinger’s equation, “Shut up and calculate!” Concerning the question of the universe’s origin, the two fields overlap. We can make empirical observations about the universe, and potentially create a cosmological chronology dating to the very first moments of existence, when the very dimensions of time space may not have existed as we know them. But this raises philosophical questions about the nature of time and space, are they features of reality that constrain and define logic, and can we think of existence in terms other than time and space? Without time, space, and order, is there anything left that might be called existence? These are questions that could be avoided by merely assuming that the universe has always existed, in one form or another, which does not require unintuitive ontological theories. Yet even this may present difficulties, because it proposes no initial cause from which every subsequent cause stems, and because it is essentially circular (though one may be accept this with some form of nihilism, like Nietzsche did).

Mathematically it's very simple and makes sense. You have energy (1) and negative energy (-1) . 1+ -1=0

It's hard to wrap your head around, but it's essentially saying that you can borrow energy from nothing but it leaves a deficit.

Alright, let's consider that the universe did indeed have a limited amount of variables which could decide what and whatnot can exist. Supposedly, there are an infinite amount of scenarios since they're isn't such a number to describe the possibilities; however, what if multi-dimensional universes actually existed? It could be possible that in one of those particular universes that you were alive at this very exact moment if another string of events didn't derail your current existence.

Such an idea is bigger than the universe itself as we see it. There's nothing to explain or support such an idea, but it is fascinating. I do believe that we live in a universe of limits unfortunately, so none of these ideas are likely true.

The net energy of the universe is, and must remain, zero

But what you refer to as "energy" should actually be called "positive energy", yes you can create as much of that as you want, out of nothing, provided you also create an equal amount of negative energy at the same time. The universe is capable of creating all the positive and negative energy it wants, out of nothing, because its not creating anything at all, it all adds up to zero.

But still, i lie in bed at nights, thinking about how time has always existed, something thats been there forever. forever in the past. its a shocking concept, and its so illogical its something that makes me feel theres alot more to this

>I am a creationist

That was the icing on the piece of shit cake you just typed. An infinite amount of monkeys typing infinity would create all Shakespeare works eventually. Trust a creationist not to grasp the concept of infinity. With an never ending amount of time occurring and a never ending amount of monkeys at work it would be expected that such a coincidence would fall into place eventually.

I understand that it's hard to apply logic to something outside of our existence. There really is no logic to it. But there's a very good possibility there is.

applying logic is all we can really do to even have a conversation about this, otherwise we could just say, we dont know, so theres a chance the cosmos was made from smegma, god was jelquing when he slipped, which is why they call it the milky way

Otherwise. Who knows, Maybe our universe is eternal and there is something beyond our idea of eternity. It's kind of hard to imagine anything once you strip the fundamental laws of physics out of the equation.

Feel free to answer it.

Also, there is a bit of misinformation but there is also quite a bit of quality content + sources. Making general statements without substantiating it make you look incredibly unintelligent.

Something has to be infinite, its like the question of "if there is a god, where did god come from?", you have to go back over and over, there can't be a starting point, so things have to be infinite.

I just can't comprehend that, therefore I think we will never be able to fully understand the universe.
