Jeff Goldblum is why life exists.
Me: guys how do we slow down the heat death of the universe?
Isaac: die.
One solution. Another comes from taking a new perspective, that we ARE the universe trying to prevent its own heat death (via our problem-solving capability). Read the new Philosophy of Broader Survival if you want a new perspective on life (and your own survival on a broader plane).
@@wbiro
I had a nice reading of your philosophy.
But it's just incredibly annoying how elitist it is your classification of beings. Believe me, it's a really hard thing to do addressing "Broader Survival'' when you have to constantly worrying about surviving the next week or month.
It's not that most people can't grasp the concept of broader survival, its just that it is irrelevant thinking about that if you live in a society or a world of massive material deprivation and concentration of wealth. Instead, it's only logical to pursue your own survival rather than worrying about humanity as a species.
That said, life and conscience are absurdly rare and must be protected at all costs.
Standard reply: you first :)
@@eduardorabassallo3717 Your own survival depends on you not dying. That means you need to research anti-ageing biotech and "cure" cancer. You will necessarily be solving the problems of broader survival in solving the problem of your own survival. Even if you live in a war-zone, if the bullets and lack of food and water don't get you, ageing still will, so just because you're not in a position to do anything about that, doesn't render it irrelevant (or pointless to think about).
Finally something where the dead bodies of corona virus could be useful

Hi Stella

@@Makkovar hi
Creating life is a parlor trick compared to what we're usually planning in this channel. :D
Yes, good video, Isaac. Could you make a video about a realistic and economical way to reverse global warming? It's the issue of the day, but also the century, if not the millennium. I've come up with this: Cover city centers, especially cities in deserts, with a large pyramid, or maybe a dome, that has solar panels, but also these cooling panels that convert heat to radiate in specific wavelengths that can escape the atmosphere much more easily. Here's a link to a video on them: ua-cam.com/video/7a5NyUITbyk/v-deo.html
The cooling panels could cool the city below, making it a cool island, instead of a heat island. Light would also be let in.
The cooling tech could also condense water on the underside, contributing to the city's water supply, and dehumidifying the city, potentially allowing most buildings to not need air conditioning systems. The city's cover could thus regulate solar gain, making it comfortable even in the hottest deserts. If more electricity is needed, wind turbines could be built on top of the pyramid.
The city cover would be supported by the skyscrapers, and could be quite tall. The cooling panels could also be a great desalination system - basically an artificial water cycle! Let warm humid air that is captured over saltwater 'greenhouses' rise up naturally in large pipes, then condense on the underside of the cool panels. The water would then be collected and run into tanks near the tops of the skyscrapers. So less power would be used in pumping the water.
During hot seasons at night (if more cooling is needed), windows at the top of the pyramid could be opened, and cool ground air would be drawn in.
Looking at the city as a whole system, and using the new cooling tech in a novel and grand scale, should lead to enormous reductions in CO2 emissions, and even a direct cooling of the planet.
Other ideas are giant "trees" made of the cooling panels over towns or just over parking lots, etc.

"Life exists in order to expedite the heat death of the universe." Lmao Entropy BTFO
It is amazing to see how much your channel has evolved over the years. It's made every Thursday a treat. Keep up the amazing work.
The stuff Isaac Arthur puts out is so underrated, so incredibly educational and fascinating. Your videos should be a college class by itself lol. Keep'em coming!
I like to think that that life is just a reflection of the universe's innate tendency to complexify. Perhaps life will eventually develop into something far greater in time. If there are other universes out there, then perhaps life plays a role in evolution on the grandest of scales. With the way you brought up the heat dissipation idea, perhaps life & entropy are more intertwined than we previously imagined. Here me out here for a bit.
Think about it. Universes that are incapable of producing stable conditions & thus form more complex structures are in a sense "infertile" so to speak. They either rip themselves apart or contract to rebound once more until the fundamental constants achieve a steady state. It does not necessarily have to be the lowest energy state but one stable enough to allow complex sub-structures to form out of the primordial froth & so on, the rest from here is history. Perhaps there really is no defeating entropy; which does not necessarily mean we cannot fight it, but such endeavors are futile & nothing more than a purposeless struggle against the inevitable fate that is the result of a universe growing inexorably old without a catalyst to give it a push. That catalyst is us - life. Life can break that "cycle" so to speak. We can produce energy densities only possible by intelligent design. The type of event that could in theory allow the universe to have "children" so to speak. Baby universes; disconnected bubbles of space-time budding from the parent universe. Perhaps that is the role of life? Simply to create a gigantic explosion. An explosion of life, of potentialities. Additional rivers of time from which new tributaries of intelligence could arise. Perhaps that is our role.
As for our role, the universe is pointless (I just want to make that point) (and now the universe has a point, meaning we create our own points). Another view I like to take is that we may be the universe trying to prevent its own heat death (via our problem-solving capabilities), which is in essence the same as what you are thinking. Read the Philosophy of Broader Survival, it delves into it-depth (and it prevents suicide, and alleviates Continued Universal Human Cluelessness) (as well as many other things) (it even has a monolith that you can leave on planets with budding intelligent life) (which depicts its internal structure)...

@@BlackEpyon So you're also positing that human-level consciousness or beyond (that can contemplate about the universe) is somewhat the ''end goal'' of evolution. Yet science has not shown this to be the case.

Since we are talking about concept of the life, there are news about biological robot called xenobots which is robot composed of the living cells. The first xenobot used the cells from Africa frog.
What...?
@@gogaschnitzel3222 s/he seems to be talking about building something akin to a micromachine or nanobot, but using organic parts to do so instead of using what might be considered more synthetic - like using preexisting frog cells instead of using carbon tubes or structures you grow yourself. I suppose to some degree you could wonder about the line between natural and synthetic in this case, but they are just terms of differentiation. Did you literally build a tiny, "metal" machine or did you repurpose preexisting cells? Blah blah blah...
@@xBINARYGODx nope. Real thing. Already made. Nanofrogs and I dont mean diminutive Frenchmen. It's a step towards medical nanobots apparently. The future is coming, the future is coming!
Good comment. Now people will look up xenobot, but usually after they try to develop their initial concept of what it is. my initial view is that cells cannot be programmed, only evolved to address specific problems... looking them up, they are groups of cells, 500-1000, that exhibit a single tendency (the desired tendency), such as targeting and destroying cancer cells. Ethical questions concern criminal use, and the solution is philosophy (which underlies all higher-than-animal decisions and their subsequent actions), where humans still suffer from Continued Universal Cluelessness (which is why some humans take criminal opportunities - an enlightened person would not) For that enlightenment, you must read the new Philosophy of Broader Survival (or go to your grave clueless, your choice).

I think "why" is a human construct. The hardest thing to escape from is our own perspective. I have no problem with reserving conclusions for a time when more data is available.
Thank you for your thoughtful vids.
Well said
I agree. The ontological weight of "why?" is sleight enough to me that I feel a response of "why not?" is a sufficient response.
Good point but you still have to ask 'why' so that people to will want to answer that question and research this topic
@Pepe The Great Do you have an origin-of-life model without an Intelligent Designer?
@Pepe The Great We probably wouldn't know unless He revealed Himself.
However, we do not have an origin-of-life model without an Intelligent Designer.
Do you have one, Pepe?
I'm not "one of the greatest minds in history" but I do have my own theory.
Everything in the universe drifts towards lowest energy state possible, and while life creates local dips in entropy, overall it increases it.
example: bacterium grows, creating a tiny bubble of organized matter, but in the process and during normal life functions it eats and it's excrement is in a lower energy state. Net result is increased entropy and it happens faster than if a batch of molecules was just left to it's own.
Very good idea. Life increases entropy.
Since 'why' is so broad, it can have many 'answers' (meaning 'perspectives').
One perspective I like to take is that we are the universe trying to prevent its own heat death (via our problem-solving abilities). A sci-fi possibility (I'll make it a Galactic Thinker short story) is, within the perspective of enlightened/non-enlightened (in terms of addressing Broader Survival), where there is an Inquisition Ministry that evaluates life on planets, and, if the planet's species have leveled out at a less-than-enlightenable level (think of a planet dominated by dinosaurs for millions of years), then the Ministry orders a cosmic calamity to cause a mass extinction to restart life on the planet, in hopes that an enlightenable species will have higher odds of developing in the cleared-out aftermath (such as humans after the extinction of dinosaurs).
Another is a landslide perspective, where life is like a landslide down the energy gradient of the Big Bang. There we are, and there are viruses (for example, though they are not alive), both tumbling down the 'landslide' (using up the universe's energy caused by the Big Bang, a negative energy gradient where entropy is increasing), and occasionally interacting, and which provides the 'energy' to facilitate molecular self-assembly and lipid vacuoles giving rise to cells and cell operation driven by chaos but enhanced by increasing the odds in a contained environment (facilitated by molecule-selective cell walls), with the functioning of their internal components driven by the molecular storm driven by what thermal energy remains in the universe.
Note that we formulate questions, and solutions, based on perspectives. In the case of the landslide, it promotes a 'dynamic' view of life (and disease), which may be beneficial in formulating questions and solutions. An example of a bad perspective is 'time travel', which misdirects questions and solutions which will fail because you are approaching the problem from the wrong perspective (the right perspective being 'change travel', or going back in change).
Hey Isaac, you ever consider doing physics classes or courses? I'd love to attend them and I'm sure many others here would as well.
Videos on basic physics would be good (for those on the level of flat earthers, for example, who lack the most basic of physics)...

voidremoved yep! Now you’re getting it. Good job!
I read this funny story about how a human discovered by chance that all life in the galaxy had been seeded and later fund out the reason why it was done. The seeders were lonely !
An idea just popped into my head so I'm adding it.
If a cell tries to reach stability as a result of life and then found its self in a place where stability was difficult, if this cell can change to reach stability, then modifying itself to reach stability would be a result of life. If the cells environment then was exposed to an extreme, the cell might adapt to reach stability, but if the environment changed, the cell would have to modify its self again and again and again. Each such change to reach stability might increase complexity.
And by result of reaching stability the cell starts to gain, functions to handle extreme environments, but that requires more energy, so to reach stability the cells would need to change again.
By affecting such a cell in a push pull environment where it has time to adapt to its current state before the next change occurs, life as we know it would evolve over time.
So in my ind life evolved because the lack of stability, and lack of stability is death to a simple cell, so it needs to evolve to stay stable.
It would explain a hell of a lot of odd little quirks that life of this planet has evolved. Life seek stability. If so, it might also cause divergent evolution down different stable paths. Throw in a slowly changing system between stable and unstable (push pull) and life could potentially evolve in any direction that seemed more stable. Too unstable is end of life and too stable is stagnation.
But how that fist cell seeking to be stable came to bo, well that's a whole different question. Maybe it was a panspermia event, a soup of chemicals being struck by lighting or aliens tinkering to see what would happen, who knows! My bet would be on either the soup or panspermia . Something triggered that first reaction that started the chain, but what?
It was a pretty entertaining video, but the word emergence was the answer for every mystery. I prefer to say that there are organizing principles in nature that result in the appearance of design or order. A hurricane could be called an emergent property of the atmosphere, but we understand the underlying principles of organization, so we don't need to say emergent. Also, while a hurricane appears to be an orderly structure within the atmosphere, it is actually a chaotic feature that forms temporarily due to underlying forces and interactions, just like life.
Short answer: "Because it can."
Is that the same reason that time and space exists?
Lol true
@@jira6423 probably more like “because it does” and life.. everything else is because it “can”

Complexity from simple rules is why I love Cellular automata so much.
There are really two questions to "why?" The first is "what caused it to exist (all the required happenstances)?" The second is "what is its purpose, if any?"
It seems to me that your first "Why?" is in actuality a "How?". Questions of "why?" (in all their forms) are often conflated with "how?". For instance asking; "Why did the universe come into existence?" as opposed to "How did the universe come into existence?". It is interesting to note that such "why?" questions still demand a "how?". We could say that the spaghetti monster created the universe but we are still left with the question; "How did the blessed noodlie one do it?". It is further interesting to note that "how" questions do not necessarily require a follow-on "why". We could say how the universe came to be (the big bang and the undiscovered physics that caused it) but we are not compelled to ask why it happened.
Personally, I would argue the two are different ways of framing the same thing but then I am not convinced that free will actually exists as an objective fact. By that, I am referring to the reality that the agent's beliefs are themselves a product of the agent's nature and its experiences. Thus you could frame explaining the agent's actions by attempting to infer the intended change in world state they hoped to achieve or in terms of the experiences and influences that lead them to conclude a given change in world state would be desirable and that led them to believe their proposed solution would accomplish that end. After all designing, something for a purpose is a product of believing that a hypothetical alternate world state would be better and believing that you have the means by which to transition to that hypothetical better world state.
@CaptainFrantic - You could call it "how" but it doesn't change anything. The two big questions still are what caused it to come into existence and what is its purpose?
to ask what caused it to exist implies that there is something that caused it which is an assumption that you came up with. Same with your second question, it implies that there is a purpose, which is very abstract.
@@VytenisR1 Did "it" (whatever you're referring to) begin existing without a cause, or has it always existed?

Easy answare:
The purpouse (and the reason of its a thing) is to not die.
Technicly everything that there is only there still beacuse the fundamentals of existence allows interactions to be preserved or created, in some cases cyclicly recreated.
Life as WE know it got to the point where it had the most avaiable possibilities to preserve thus fullfill its purpouse which is to not die (what is basicly chese to exist in some more desirable manner).
Since conciousness is pretty much the mainstream way of thinking about life, i must tell you the sad tale that it is simply a state of interactions where the amount of information from interactions excedes the parts that can recognise that information and respond. However since the chain of reactions do not stop and cause other interactions in other areas that also generates information that reaches the parts that can recognise these information for furthure reactions causes the whole recognise section to look chaotic / ill-logical something that is the oposite of preservance which is a must to stay exist.
So in this chaotic looking part the act of conciousness is the attempt to uncover the unknown links betwean informations sent to the responder (whole body actually but big part in the brain).
If existence is trully random like how the Heizenberg principle says, then conciousness is inevitable since there will always be reactions happening without known reasons that creates the unkown which conciousness attempts to uncover.
So if we keep the principle that anything concious has to be a form of life no matter what and existence has a random noise filter on it then life is inevitable and existence is most likelly eternal and the universe probably infinite which is cool since it is absolutelly possible that even then we are the first ones, and the next one might not happen either ever or in the next trillions of billions of years.
Yup, life is an agent of entropy.
Oh BOOOM 😲🤯😧
The Anthropic problem also relates to basic contextual problems in general. There are things we can't know or learn about because of the context in which we exist. This comes up a lot in Cosmic Horror writing. In theory there are other observers that exist in entirely different contexts that we're totally blind to, and possibly vice versa.
There's also funny ideas like our universe exists solely to dissipate heat safely for another, very different universe that created this one solely for that purpose. They neither know nor care that life exists here. Eventually there will be more Big Bangs, which is simply them offloading more waste heat and some small waste products, from their perspective. It's entirely a Horton Hears a Who situation.

I've seen them all and I think that might just be the best one you've ever done Isaac - bravo. I _love_ "life exists to hasten the heat death of the universe" - I'm definitely stealing that one. One thing though, you spend the whole episode from a physical-emergent-complexity point of view - and yet you still contend that you personally have free will. I still find it hard to square that circle. Keep up the awesome work.
Found something incredibly cool with Langton's Ant . Maybe someone on here can explain mathematically why this happens. If you choose custom behavior then put this in: "LLLRRRLLLR" it basically makes a perfect highway right from the beginning. That's not the coolest part tho. You can add any length chain of R's and L's in any order to the end of that chain and it will still make the same perfect highway in the same direction the only difference is the colors.
Life exists to create information, as a means of combating entropy. Least that's my interpretation.
Now to watch the vid and see how wrong I am heh.
Its the other way around, humans increase entropy. All life increases entropy to maintain being alive. While entropy only increases, complexity on the other hand will peak and drop at some point.
Information exists whether or not anyone is there to discover and interpret it. If humanity dies off, and all our works are erased, and no one else in the universe ever learns we once existed, the fact will remain that we were here. The universe remembers because it is the root of all information.
Rather than 'interpretation' a more useful word is 'perspective' (which results from interpretation). There are many perspective to take, the question being which one is most useful at the moment (and 'toward what' is answered, at the highest level, by the Philosophy of Broader Survival - read it).
As an attempt at a clarification of my statement, think of Voyager and the golden records inside it. Neither would have existed without life, neither will increase entropy by a significant amount for most of their existence - the record in particular was made to resist degradation over time. Thus life, in the form of humans, has created something that more effectively combats entropy than anything we've thus far created. If humanity dies tomorrow, we've at least left a tiny mark in the unwinnable war.
Sure entropy will decay the probe and it's contents, eons down the line, as even solid matter does flow. But it's a first step to us creating something that might even outlast the last black holes, and that is also, for practical purposes, impossible for a random collection of matter to arrange itself into without intent behind it. In other words, our very curiousity and urge to explore or invent long lasting artifacts is our bulwark against entropy. As long as we can extract enough energy to alter the world, we are fighting entropy in a local sense, even as we dump our waste into the universe to increase it. Seems suitable to me considering how contradictory we can be as a species.
Or to put it another way, conscious life fights entropy - it tries to resolve uncertainties, to make the unlikely happen, to do the impossible. It does this because it wants to delay the onset of death (and decay, which is very entropic). Unconscious life simply consumes and propagates, but doesn't really do anything to "fight" entropy any more than a planet of particularly unusual composition.
But thanks for your replies, some nice food for thought and I will be factoring them into my future thoughts. I'm very much the crackpot kind of philosopher so anything I put out there should be taken with a large handful of salt :)
@@BladeTrain3r good points. But making a voyager and the golden record we have increased entropy much much more than if would have done nothing.
At ~ 25 minutes, he brings up the point that general principals ("life is a consequence of heat dissipation and entropy") do not guarantee that life will pop up whenever conditions are met. Certainly true. But I'm not sure Robert Forward's Dragon Egg scenario is a great example of that. He says life wouldn't form on surface of neutron star because life depends on chemistry, and there's no chemistry going on there. But Forward's whole reason for writing this novel was to explore the possibility that NUCLEAR chemistry could go on there. If it could, it would be far more rapid than "electron chemistry" that we're familiar with -- from which the novel's plot derives.
It seems very unlikely nuclear chemistry could actually become complex enough to create this version of "Life as we do NOT know it". But if you allow that iffy proposition, then it could check off all the boxes required for what we call life.
His larger point, that life won't automatically arise everywhere the basic requirements are met, is surely correct however. You can't just collect an energy source, a body with liquid water and all the right elements, and expect life will always pop up eventually. But at this point, we are far from being able to predict just when it would, and would not occur, or even what the probability would be.
Man, i cant wait to watch this one!!
I've given the theory that life occurs as a mechanism to increase entropy, as well as its philosophical implications, the name "moral thermodynamics." I intend to proselytize vigorously on its behalf.
42 is the answer to the Ultimate Question of Life, the Universe, and Everything, NOT the answer to life!

I thought "42" was Jackie Robinson lol

I like to think and believe that life exists in order to figure out the last question. How to reverse the heat death of our universe?
2:25 Chocolate covered DNA. My favorite!
Lol, I had the SAME exact thought!
There's a negentropic principle in the world, forcing things to arrange themselves in more and more complex systems. From the uniformity and simplicity of the early universe to the birth of heavier elements in the hearts of dying stars and the countless ways in which they combine. But the universe isn't chaotic; it's just complex and growing ever more complex over the aeons and finally reaching a logic depth where self replicating molecules emerge. Something like that was bound to happen at a certain depth of complexity (doesn't mean it was bound to happen everywhere by the way). And that's what life is, an inevitable manifestation of the negentropic principle that forces matter to arrange itself in ordered complexity growing with the arrow of time culminating in a brain that can comprehend such concepts.
The reason why this doesn't contradict entropy and the laws of thermodynamics because those deal with heat, this here deals with information. "Information" is not only an abstract human concept, it's something that exists. More even, you cannot deny its existence because all denial of information IS information. Basically: the Universes' information get's more complex as it matures and life in an emergent phenomenon of that process.
So yeah, there you have the answer to the big question, in the comment section of a youtube video. Can't claim no one told you.
@@JohnStephenWeck I never claimed that information was something that existed without a physical carrier, so I'm not sure what you are responding to. I just proposed a view that focuses on the information so it's easier to see what is actually happening: while matter might be subject to entropy, the information carried isn't - for whatever reason, information didn't grow in disorder or randomness, the exact opposite happened. Order, functional order emerged. The universe didn't grow in chaos but in complexity, to very distinct things in systems theory. There might not even be something like chaos at all, just complexity beyond our means of understanding that we give that name.
Life exists to continue existing. That is purpose. That is why. That is the fundamental priority underneath all others. Because each of us matters, inherently, beyond any excuse we will ever imagine.
Even at over 400K subscribers the comments are constructive, meaningful and even the jokes have a connection to the videos. This has got to be in my opinion one of the greatest science channels on UA-cam. I'm glad Isaac pulled through and didn't give up early on.
Whenever I think I came up with an original explanation to something, Isaac Arthur always steals the words right out my mind. It’s nice to see other people talk about these kinds of things in depth
Repent simmers, and give glory to The Algorithm, lest ye be cast into the Great Recycle Bin!
Also, don't forget, next Sunday is our potluck, so please reach out to Sandra and let her know which dish you plan on bringing.
you joke but it is no joke. Jesus is the way and the life and to get to the Kingdom you have to go thru him. Good luck.
voidremoved ok, but that hardly seems fair. How is an eighth century Hindi supposed to know that? Or a pre-colonialization Aztec for that matter? You’d think the progenitor of creation would have a better system for salvation. Now I’m not denying Christ or his divinity, but I have my doubts that saying “ok, I’m team Jesus” is the only way to an afterlife, good or bad

@@voidremoved Funny how an omnipotent deity that wants everyone to know about him, only communicates with a specific area of the world, in a specific language written in a compilation of scripts full of contradictions.
If the multiverse exists and there's a possibility of faster than light travel, if infinity does exist and adaptation does occur, can a being achieve God like powers, and if so with these abilities could there be any universe within the multiverse where that entity would not be God given it's abilities
With the death of Terry Jones I would refer to Monty Python - The Meaning of Life and also their final song from "The Life of Brian" - "Always look on the bright side of life ". :-)
'die' hahaha.. oh mannn! this is just about my favorite episode
I love the joke at the beginning
My lucky day. I will only have to watch this vid 756 more times before I fully understand the depth of what is being proposed.
Well...since I haven't seen anyone else say it....
The last time I was this early, abiogenesis hadn't occurred.
Brilliant! Your best episode yet!
Life's teleological "why" is to overcome the entropy that fosters its existence in the first place. Only intelligent life can possibly do this. Your subsequent video on escaping the consequences of entropy is a first step to this.
I kinda thought we are here to; love and be loved.
why would you just *assume* that the alleged “true reality” that contained whatever “conscious agent” “designed” our simulation would require its “life” to have originated at some point in time, when for all we know, “time” is exclusive to our simulation?
EDIT: oh you answered me lol 24:49
But his two answers were vapid. Read the Philosophy of Broader Survival if you want the serious (and more sane) answer.
Happy Arthur's Day! A bright point in an otherwise astronomically large and ever expanding dark universe!
I was hoping for a 42 point list.
I regret I can't like this video twice, Isaac is talking about what I'm thinking, I love it.
im early and i dont have a joke. but its Chinese New Year this saturday. so i wish everybody here Happy Chinese New Year.

Because ...
1.[insert any deity or deities] wanted life to exist.
2. We don't know YET.
In my religion I called those "deities" mom & dad 😂💯
Actually it's "because it can" but good try sport
1 is invalid as mentioned in the video because you could ask the same question for the deities.
@@onlyplayaseattacoswiththei9433 What is the first thing in the causal chain that led to you?
I assume you're smart enough to have thought about that.
@@Triffgits What is "it" in your answer "because it can"?
Isaac you deserve a medal, your video's keep getting better and giving it a hitchhikers guide intro was sublime
26:40 I've seen enough hintai to know where this is going.
Could you do a video on why anything exists? It's because non-existence is a paradox that self-collapses into existence, *something* has to exist because *nothing* can't (well that's my theory anyways).
Third Position Indeed my theory is a little nuanced than I laid out. If all possibilities were realized the multiverse would start suffering from something sort of akin to the grandfather paradox wherein super advanced civilizations could begin to manipulate the multiverse. Therefor I imagine life to be a sort of retrocausal bootloader for the Big Bang in a sort of closed time loop, or some other explanation that only involves a single Universe or some other way of getting around Owlman destroying the Multiverse.
@@IndigoXYZ18 That's assuming there is a multiverse, also there is no cyclical time because there is no cyclical universe. The space time theorems tell us that.
WaterspoutsOfTheDeep Like I said I have my own qualms with the multiverse theory (at least as it is conventionally presented). By no means am I closed the possibility, but I'm not as certain as many are. As for it not looking likely we live in a cyclic Universe, I'm not positive we are although I see contrary evidence that this is an impossibility. Either way regardless of how fringe or mainstream your cosmological perspective may be, I don't see any version of events where in any of us are even remotely close to uncovering the inner most secrets of the Universe, such that it doesn't matter who is marginally closer to the truth (within bounds of reason, obviously the moon isn't made of cheese) given how far we are likely from a complete understanding of the most fundamental nature of reality.
2:01 wtf are those guys even doing? Why is that dude wearing VR goggles?

Science!!
After all these episodes you've made over the years I really would've expected you to run out of things to talk about. Then you're like "Oh btw, episode on postponing the heat death of the universe coming out in a few weeks" and I'm all excited for it. And then at the end you tease the O'Neill Cylinder video and I'm like "Oh hey, that's another thing I need in my life!" It's kind of amazing you've managed to cover so many subjects in such depth and are still putting out videos that people can get excited for.
Why life exists?
Because it can. That's literally it.
Your writing is unbelievable--just fantastic.
How about an episode on "steampunk/deiselpunk" space technology?
That genre is not realistic.
I don't think alternative history is in the scope of this channel.
wrong channel.
Star Wars.
Loudably yelled WOW! to this video while drunk LOL
We *all* should ask this unique and wonderous question to the most unimaginable; 'lifeforms' on the planet and known biology; *Virus'es*
Eh, viruses are just degraded cells with only 1 part that is truly needed to multiply in a medium where machinery for virus creation (our cells) are already presented in big numbers. Just how there are parasites which can't live without a host because they lost energy-demanding functions that their host will provide for free anyway.
@@Crazy-Drokon Correction: they are not even cells, they are DNA fragments that can still replicate given the right environment (inside a cell).
I know this isn't "super relative" to this video, however I was watching a video about a technology to create 3d images in color, by using ultrasonic waves to levitate a small ball rapidly, creating moving shapes.
I was thinking this technology could somehow be altered, to fling a ball of plasma, or some Hydrogen around rapidly as a Lightsaber. Probably more like a "Proto-Saber" but got me thinking that with Elon Musk's neurolink making Psychic Thought transmission a reality in a decade or so, why not go full Jedi?
Good mind - making connections of disparate things to come up with something new...
Because Science did a video on lightsabers. The heat alone would be deadly. Check it out!
@@Suprkpa I have seen it, and he was talking about a lightsaber as science could develop it in his eyes. This specific technology had not been revealed in it's current form, and the heat would not be a problem, with a few particles of plasma flying around at super sonic speeds via Ultrasonic waves., Probably would be useless at cutting into metal, but into meat?
I think _O'Neill Cylinders_ is my favourite episode.
I'm looking forward to next week :)
Check out Star Lifting and Void Ecology! They're awesome.
Life: *exists*
Everyone: "Why?"
Read the new Philosophy of Broader Survival for the deepest (and broadest) answer, and the highest form of the question.
Only Isaac Arthur can make a video titled "Why life exists" and noboby bats an eyebrow.
All my eyebrows are up to bat
dmt told me conciousness is universal and every life form taps into it with different capacity. so life is the means of experimenting conciousness which is the universe. for real i dont know why life exists but i know my purpouse in it but it's subjective. iam here to experience conciousness. love your channel btw. Keep it going
Tolbert Gaming - Meditation led me to believe that consciousness is universal and that some fundamental property of reality which imparts a capacity to exchange information between points is the key element of this. It is perhaps something basic like time - a dimension that informs all points at once. This intrinsic capacity is everywhere. If you think of that bare capacity as a two dimensional sheet, consciousness emerges when that sheet is “folded” and one fold can become aware of another. In life this folding becomes a complex standing wave form as the exchange of information between these folds is made more stable and allows lasting traces by converting the exchange of information into more persistent physical changes. Within the human mind and brain these folds of bare awareness produce consciousness and further folding of consciousness bets self awareness.
Cosmic Landscape - I am not so sure of that. There is a pretty decent body of literature that would disagree with your statement. Regardless, using drugs to alter your consciousness would seem to be a much more dangerous endeavor, and more prone to misinterpretation, than other approaches to exploring experience.
Drugs don't reveal anything. You are fooling yourself and wasting your time.
@@ColdHawk Your error is in the word 'believe'. Why just believe when the knowledge is out there? For a better (more sane, and the ultimate) philosophy (perspective) on life, read the new Philosophy of Broader Survival (please, it will straighten-out your nebulous mind).
Isaac so pleased your high quality, infirmative videos have been so well received that you have the 450k + subscribers.
Alternative question: "is life inevitable"?
Because if the answer is 'no' then we may be the only ones around.
Universe replies: Not enough data-sets
Yet 'we're ' not the only ones, obviously. I Know, it goes without saying. Not being rude, just stating the established.
@@JoeWhite3572 Not to be rude but there is no evidence at this time to support the above 'obviously' statement. Zero. Possibly sad but certainly true.
The spontaneous emergence of life its subsequent refinement into unimaginably complex organisms capable of intelligence are such hugely improbable occurrences, I would not be surprised if we were, in fact, the only ones... ever.
Which would make Elon Musk the most brilliant being in all existence and Jeff Bezos the richest, by far, Greta Thoronberg (sp?) the craziest and most hysterical manifestation in nature, and Netflix the largest streaming service in the entire Universe.
@@arthdenton are you joking? It's called established due to being proven of its own accord. That's how Knowledge/Truth works.
Consider all the planets with Life. You can't exclude them.
Earth wasn't excluded, and still isn't excluded, regardless.
Life exists in opposition to entropy, yet quickens the process.
It's a damned Ouroboros.
