Are quantum fluctuations truly random? Does random exist in nature or is it just something that seems like randomness from our perspective? If you could reverse time to the moment of the Big Bang, would the resulting universe be exactly the same as this one, or could there be different physical laws? I guess I am asking whether the universe is a closed system. If we had could observe and record the Big Bang, could we theoretically simulate the entire universe including ourselves?

Be nice. Asking here since /sci is dead. This is sort of related to the philosophical ideas of Eternal Return and Amor Fati.

If the universe ends in a crunch (not likely), and is indeed a closed system, how autistic is it to think that if there is another Big Bang, that it would be exactly like this one down to this thread?

This is exactly the type of response I always get. Just answer the fucking questions or explain why I am not ready.
>>
>>2297511
If that was true, what about free will?
>>
>>2297611
What about good and evil? Free will is a mind game we play with ourselves. We will never have information from the Big Bang, so we will never be able to predict the physical future. We are the products of the universe and there is no "soul". One thing just leads to another, we move through life like just like a rock flies through space.

I dont think I am making time assumptions, I am using time as a way to be more precise about the information I am seeking. Maybe I dont understand what you mean by time assumptions.

>If we had could observe and record the Big Bang, could we theoretically simulate the entire universe including ourselves?
That sounds like determinism. Free will would not exist.
>>
>>2297633
I guess it is determinism, but physical determinism, and one that we will never have the information to use. What if you ARE actually just a collection of atoms that resulted from the natural processes of the universe? What if your "rationality" and "modern behavior" is not as extremely advanced as you think it is?
>>
>>2297610
Not him, but this kind of speculation is the kind of thing one should only undertake with a solid basis in the sciences involved. I know I'm not equipped to help, though I'll offer what little I've heard: as far as we know, there are several quantum processes that are indeed random, and even attempts to account for some manner of unseen cause behind them have come up with nothing.
>>
I am not trying to affirm my ideas or a expound cosmology in which the same humans exist in a recurring, cyclical universe. In fact, I want you to prove to me that I am wrong without saying "You aren't ready for this discussion". The best way to do that would be to answer my question about the nature of "random", or explain how the universe is not a closed system.

>Does random exist in nature or is it just something that seems like randomness from our perspective?

The universe from the perspective of this dimension is indeterminate, not random.
>>
>>2297665
The Wikipedia entries on Quantum Mechanics and Particle Physics would be a good start. They'd probably include links to additional reading as well.

The thing about sciences like this is that they require a solid basis in multiple intellectual disciplines to really grasp.

There's so many memes in your post it's a shame.
>>

From what I am reading, MIT physicists think it is impossible to prove absolute randomness
https://www.technologyreview.com/s/418445/first-evidence-that-quantum-processes-generate-truly-random-numbers/
I get that I might never fully grasp it. I want to hear from someone who does grasp these things whether it is completely absurd that what i posted in the OP could be a physical reality, or whether it is theoretically possible (in the case of a Big Bounce) that the following universe would match this one. I get that Nietzsche was not the greatest at physics.

You're probably not going to find that person on 4chan.

Also proving absolute randomness would be impossible, because there's always the possibility of a hidden cause. Hence why I said as far as we can tell.

That said, I greatly encourage you to keep looking for your answers; too many philosophers outright ignore the physical sciences these days.

are you FUCKING kidding me? in a closed system there are no external factors. If an experiment you run is in a completely closed system, you will get the exact same results every time. If you don't, its not a closed system

No, these memes are too dangerous for you, kid. So much so that you had to link to Wikipedia. Clearly define everything you mentioned in your post. *To the most minuscule point*. I'll be waiting. Dude... is not a fucking definition.

>Does random exist in nature or is it just something that seems like randomness from our perspective?

There is no conceivable way it would make any difference either way, and it's impossible to determine. The definition of a moot point, like arguing about how many angels can dance on the head of a pin (it's four, by the way)

>If you could reverse time to the moment of the Big Bang, would the resulting universe be exactly the same as this one, or could there be different physical laws?

This we do know. The laws of nature seem to pre-exist the Universe, but the pehnomenom known as "chaos" ensures that a "play-back" rest would play out completely differently, same basic "building blocks" but new stars and new worlds, no Earth and Milky Way.

Exactly. Look at it this way. Once you remove all of the artificial constructs (phantoms, spooks, memes, ideology, preconceived notions) what are you left with?
>>
WW1 started because Franz Ferdinand stopped for a sandwich at a shop right across from where his assassin was standing.

If he decided to skip the sandwich, the war may have happened years later when all the generals who didn't understand modern warfare had died off. Or, maybe the war would have been delayed long enough for the Germans to develop even better guns that ultimately win the war for the Central Powers. Or, maybe the war wouldn't have happened at all. Some smaller scale conflict happens instead that shows the destructiveness of modern weapons and scares the European powers into detente.

No, I don't think it's possible for the universe to play out the same way twice. Reality is too absurd for that to happen.
>>
>>2297912

Not that faggot but memes are not spooks.
>>
>>2297688
Nietzsche's Eternal Return is entirely hypothetical and it matters not whether you will actually relive your life infinitely because it is a measure of how you want to live vs. how you are living. It's a thought experiment entirely focused on you as an individual, in this life.
>>
>>2297960

This. Uncertainty principle itself suggests no two Universes can be exactly the same.

>>2297971
Does the universe differ from an "experiment"? So you are saying that it is actually not a closed system?
>>
>>2298001

Whether it's closed or not is irrelevant, UP rules out perfect repeatability at the quantum scale. And when you reduce a whole Universe to that scale, who fucking knows what predictability means, there's at least one fundamental force that hasn't yet been discovered because it only acts at Universe-forming energy levels, maybe that unknown force somehow determines the physical laws that make matter as we know it possible.
>>
>>2298022
>one fundamental force that hasn't yet been discovered because it only acts at Universe-forming energy levels
>Universe-forming
>force
>not discovered
Friend, have you heard the good news?
>>
>>2298028

No, dummy, the force acts IN our Universe, it didn't CAUSE it. Or actED, rather, since the Universe has been too "cold" since the first fraction of a second for this force to be active.
>>
>>2298049
So can we figure this out by figuring out everything else about the laws of our observable universe? Would you have to have an understanding of this force to know the "theory of everything" every physicist memes on about?
>>
>>2298028
You joke, but wouldn't it be something if consciousness could be tied to dark matter/energy somehow? Some variable that's chaotic and unpredictable, yet fundamental to the system.
