Does anybody have any scientific theories as to how consciousness might persist after death? Or are we really just supposed to act like we're racing towards an empty void and that's okay

Why the fuck have we not really moved past Schrödinger's cat and the double-slit experiment nearly a century later?
>>16870864Is that what happened when you failed the undergrad QM 101 class?
>>16869928Actually the main one has failed. The copenhagen explanation about collapse theory failed with the various delayed choice experiments and so they had to invent reverse time traveling particles aka retrocausality to explain the experimental results. So now you have QM - wave function realism + collapse + reverse time travel nonsense added. Three different patch work was required to explain QM for copenhagen interpretation. Its a frankenstein monster that is ugly as fuck.The only QM that is still relevant is Many Worlds. Its just QM as is. There's no claiming the wave functions are just math with no real description, extra collapse isn't needed, there's no reverse time travel nonsense needed.
>>16870893>The copenhagen explanation about collapse theory failed with the various delayed choice experimentsWhich calculation failed? What misprediction was made?>they had to invent reverse time traveling particles aka retrocausality to explain the experimental resultsWhere exactly did they need to do that?https://web.archive.org/web/20211108031014/http://motls.blogspot.com/2016/10/no-retrocausality-in-qm-delayed-choice.html?m=1>The only QM that is still relevant is Many Worlds. Its just QM as is.They're completely inequivalent.https://www.quora.com/Can-you-explain-the-difference-between-quantum-mechanics-and-the-many-worlds-interpretation/answer/Luboš-Motl
>>16870893>wave functions are just math with no real descriptionIt's just fallacious to shift the burden of proof away from the one making a positive claim about the reality of something (e.g. invisible pink unicorns), onto the skeptic who dismisses it.https://www.google.com/books/edition/Quantum_Theory_Concepts_and_Methods/IjCNzbJYONIC?gbpv=1&pg=PA17>We have no satisfactory reason for ascribing objective existence to physical quantities as distinguished from the numbers obtained when we make the measurements which we correlate with them. There is no real reason for supposing that a particle has at every moment a definite, but unknown, position which may be revealed by a measurement of the right kind, or a definite momentum which can be revealed by a different measurement. On the contrary, we get into a maze of contradictions as soon as we inject into quantum mechanics such concepts carried over from the language and philosophy of our ancestorsWhat does a "real description" even mean? Wavefunctions can't have a "real description" algebraically because they're complex-valued. They can't have a "real description" physically because they're not measurable. There is no SI unit for "wavefunction". Only observables are measurable, and measuring one always yields an element of its spectrum. A wavefunction is obtained by picking a CSCO, doing a preparatory measurement for a pure state, and parameterizing it. A pure state isn't even the only kind of quantum state. Mixed states need density matrices, not wavefunctions.>extra collapse isn't neededThe definition of QM includes the collapse postulatehttps://www.google.com/books/edition/Visual_Quantum_Mechanics/GOfjBwAAQBAJ?gbpv=1&pg=PA103https://arxiv.org/pdf/2207.11350#page=7If you drop that, then you're not doing QM anymore. Just like you're not doing Newtonian mechanics if you drop Newton's first law, Euclidean geometry if you drop the parallel postulate, or Peano arithmetic if you drop 0 being a natural number
>>16871069Real description is just that. The wave function is just a description of the model of QM reality as it shows us. There's no "its just a math trick bro" argument inserted as a means to diminish wave function out of QM, when wavefunciton IS the QM. This isn't to say QM is the reality we live in, but its a model that that explains what the wave functions are as such. A model with many worlds inside. Just as classical mechanics only allow one universe, QM allows many worlds. We dont deny the reality of classical mechanics, we merely scope it to classical mechanics. As such, QM's wavefunction its appropriate many worlds are part of the same model of reality.Everyone now knows QM isn't the be all end all model of reality either. Strings's got infinite many worlds or something. Thats a model that cant make otherrs cant sense of either, especially since classical mechanical guys dont even want to take QM serious enough. Classical mechanical interpretation of QM is just an artifact of lower bound model trying to explain higher bounded model.
what the FUCK is with dreams? I think its one of the spookiest mysteries of modern science. weird things about dreams:>the ability of your subconscious to create vivid, breathing worlds engaging all your senses and reacting to all of your conscious actions and thoughts is kind of frightening to me. goes to show you how immensely powerful our subconscious is and how much of our actual decision making happens without even processing why.>what is the evolutionary advantage of these resting hallucinations? is there even one to begin with? we know animals dream too, so it would suggest there IS some kind of benefit to this, but what could it possibly be>the nature of the dreams themselves. why do so many of them seem to involve our deep seated fears, anxieties, regrets, and hopes for the future?>lucid dreaming and partially lucid dreaming. I have a weird thing where I will generally suspect something is a dream, and I will worry that its not real (because my dreams are usually the life I WISH I had) but convince myself in the dream that its real. I also have an ability to consciously stop the dream once it gets uncomfortable and I want out. its like I dont know Im dreaming, but then once it gets scary I immediately know I can just end it anytime, then Ill close my eyes and wake up. fucking weird>what it says about the very nature of consciousness itself. why is there even a "me" consciousness seperate from the rest of our brain to begin with? why does this conscious retard need to be entertained in some imagined space?the more i think about it the more fucking weird it is.
>>16871053There is also a mysterious evil dude reappearing who is very super powerful and is injecting people. Anyway I'm not the son of this dude and I have super powers. Apparently these are alien fruit and whoever eats them gets powers. He explains to me that once a blob matures in my hand this is when my powers will be at their zenith. But also there is a second blob. When it matures the alien overlords will take over my body and invade the Earth. He got rid of his second blob but won't explain how. He says he guesses it's his personality. Anyway apparently there is some sort of organization which has super powers. They inject the girl from the classes and the other people from the classes with some experimental super power stuff. They expect them to go insane like it happens sometimes. I follow them, but they turn out ok. I explain what is happening to the girl. And we are in some flying cars or trains. She is the more powerful from these guys but I'm more powerful than her. And the only one who is more powerful than me is my father. But I have the potential to surpass me cause im just a teenager or something. I tell the car I'm the guy from the German classes. And she says yeah I remember you got kicked out from it.
>>16871055Next scene they are giving the magic fruit to everyone in the population. They decided it's the best way to defend from the aliens. THere is with a junky who goes to the get some food from welfare. He is very thin. He takes the food which is injected with super power serum. He doesn't know, nobody knows, but he has drugs hidden in the food which he takes. He is very happy. But then a voice sounds and tells him to eat the food. He is forced to eat and he likes it very much, because it's like a drug and it gives him super power. The end there is some sort of convention. The mysterious man from the start, my father, who was an evil figure in the beginning but then good, is part of the council of the people with super powers. It is held in some place with super power people who live in a cave like bads. There is a member of each super power clan speaking and they have their entourage too. My fathers name is Marzly. A woman challenges him and says they never sanctioned to give everyone super powers. But he did it anyway. I don't remember how it ends but I woke up.
>>16871028Dream world is connected.It's like an alternate reality.Your previous dreams influence the next one and your dream self knows every other dream.One time I dreamt I was being chased by a monster and it was trying to kill me.At some point I gave up and said whatever just kill me I'm tired of running.It slashes my chest and kills me.Only I didn't wake up like normally when you die in a dream.I rose and became a ghost.After this dream, my dreams have been completely altered.
>>16871028>what is the evolutionary advantage of these resting hallucinations?Here is my guess. Not all of your brain is asleep at once. There are still bits that are occasionally active while it is recovering that result in experiencing nonsense information. You forget most of this quickly after waking up because animals who remembered were disadvantaged by fear and confusion from this nonsense information while surviving in the wild. Something similar to hallucinogenic plants using this as a defense mechanism. Either that or you forget it quickly because your hippocampus is not recording it while you sleep.In any case I don't think it's particularly meaningful or prophetic. These are just things people think about while awake but disorderly because their brain is recovering from a day of activity and only partially active.
>>16871062>In any case I don't think it's particularly meaningful or prophetic.I want to add they might still be a good source of some interesting stories and creative ideas.

What are my easiest options for making burnable fuel out of used car engine oil? I don't care about safety and the environment, just minimally burnable fuel.
>>16870886I'm thinking about making biodiesel, but I just wanna make stuff as proofs of concept and use a model engine to test them
>>16870838The used car engine oil already is burnable fuel. The easiest option is to do exactly nothing to it.
>>16870902cool i think biodeisel is very realistic there are lots of people who have done it before, good luck
>>16870905Will look into that as well :)
>>16870838Unless you got some equipment for cracking oil, which is probably only useful if you're sitting on tons of old engine oil, I'd say just mix it with some more combustible gasoline and burn it.
The Core Difference (Find vs Verify): Problems in the P class are those whose solutions are easy to find and easy to verify. Problems in the NP class only mean the solutions are easy to verify. To this day, nobody has found a fast method (polynomial time) to FIND the solution for NP-Complete problems.NP-Complete as the "Wall" of Obstruction: NP-Complete problems (like Clique or Subset Sum) are considered the hardest computational problems in the universe. For over 50 years, researchers have tried to solve these problems with P-Time algorithms, but NONE HAVE SUCCEEDED! The absence of a discovered solution is the strongest empirical evidence that fundamentally, FINDING a solution for NPC is much harder than simply CHECKING a solution.Cosmic Implications: If P = NP, then all the hardest optimization problems in the world—from designing the perfect drug, breaking all modern encryption codes (including banking and military), to creating a super AI—could be solved with relatively fast algorithms. The fact that encryption technology still works and optimization problems are still hard is the real-world evidence that rejects P = NPThe Answer was P = NP
>>16870728>"knows" P!=NP but nobody can prove it mathematically.P != NP is proven every time you calculate an algorithm as nondeterministic polynomial time. It merely isn't "exhaustive" enough for you retards who insist that just maybe a compatible polynomial algorithm might exist.
i spent on and off 10 years researching this problem, looked into many official and non official np complete problems, dug into np hard problems too which there arent many of them if you think about itAll in all i can wholeheartedly say that i havent inched closer or further than what other people have done even though i have some insights for both cases, leaning more on the p=np case>The fact that encryption technology still works and optimization problems are still hard is the real-world evidence that rejects P = NPunfortunately this argument is as weak as the old dumb-creationist argument: if people came from monkeys why are there still monkeysthe point where i left off was looking into the case for graph isomorphism, its relation to NP problems, degrees of logical transformation freedom and how does it relate to Rado graphs since if not all NP complete instances have an element of chaos/randomness that more or less force you to follow some optimized route of check and search i quit science and im off fucking around with something completely unrelated, the whole computer science scene is a scam, most "academics" are retards that i can snuff out with two or tree articles i can write in less than a weekonly person worth discussing this is prob Scott Aaronson and the other optimizing mt.rushmore people who im not sure if they are dead or notAMA

virtually every task I try to do take me 2x-3x longer than everyone else. I believe this is an ADHD thing. I am not talking about procrastination here I am talking about something else. time blindness or general distractibility or poor planning or something, I'm not sure.I just would like some scientifically supported solutions for this or at least some articles to read up on this phenomenon in order to try to work out my own fixes.I am already searching for readings on my own but I figure it wouldn't hurt to ask others for some extra help.INFO ABOUT ME:I already am medicated.I have recently started employing CBT strategies that do seem to help.I do not do any exercise but I plan on making cardio a mainstay in my routine (is this really as effective as I hear for ADHD?)My sleep schedule is non-existent but even when it is solid tasks take forever.I do not pay very close attention to my diet, I do not eat fast food or excessive amounts of sugar but that's it.if you have any advice I would appreciate it if it wasn't in the ballpark of>"put a loaded gun to your head and tell yourself that if you don't complete (X) task in (Y) minutes you'll fucking die."Thank you in advance. I appreciate it.
>>16869256I'll concede that there may be some minor additional neurotoxicity at therapeutic doses < 20mg, but the research I've read points towards this being marginal. I'd point to:https://pubmed.ncbi.nlm.nih.gov/22289608/ - which concluded that "METH and AMPH are equipotent at producing lethal hyperthermia and neurotoxicity in laboratory animals during the wake cycle" And:https://pubmed.ncbi.nlm.nih.gov/24333768/ - Which concluded that meth may have neuroprotective effects at FDA approved dosages.
Ignore the nonsense above about amphetamines and whatever.There’s only one path left for you now: get TMS treatment. People misunderstand it as electroshock therapy, but it’s not. It’s basically magnetic pulses fired into your head.If that doesn’t work, then kill yourself. There’s no other option. A lot of people actually improve with this.Some of it is psychological, sure, but if there’s a physiological problem, then no matter how noble you are or how strong your will is, you’ll eventually break.It’s like telling yourself, ‘I can ignore gravity,’ over and over again — the moment you step off a building into empty air, you fall and get smashed to pieces.Anyway, if this doesn’t lead to improvement, then your soul has already rotted. Your only choice is suicide and reincarnation.Or you could become a spirit medium — sometimes that works as treatment. But in that case, you’ll have to live with a supernatural entity for the rest of your life.Forget about dating, marriage, or children. Everything will end in ruin.Good luck

>>16870880Did you read your own source? That's a trivial question to answer. >We conducted a literature search to identify papers published prior to the early-1990s that include climate model outputs containing both a time series of projected future GMST (with a minimum of two points in time) and future forcings (including both a publication date and future projected atmospheric CO2 concentrations, at a minimum). Eleven papers with 14 distinct projections were identified that fit these criteriaBy obvious logic, any paper prior to 1990 that failed either criterion listed were not included. Likewise any paper after 1990 was not included. Are you brain damaged?
>>16870880LMAO HOLY SHIT>A number of model projections were inconsistent with observations on a temperature versus time basis but are consistent once mismatches between modeled and observed forcings are taken into account. For example, whileN77 and ST81 projected more warming than observed, their implied TCRs are consistent with observations despite forcings within—though on the high end of—the ensemble range of observational estimates. Similarly, while H81 Scenario 2a projects less warming than observed, its implied TCR is consistent with observations.
