At this very second, you are on a narrow ledge between life and death. You probably donโ€™t feel it, but there is an incredible amount of activity going on inside you. And this activity can never stop.

Picture yourself as a slinky falling down an escalator moving upwards - the falling part represents the self replicating processes of your cells, the escalator represents the laws of physics, driving you forwards. To be alive is to be in motion but never arriving anywhere. If you reach the top of the escalator there is no more falling possible and you are dead forever.

Somewhat unsettlingly, the universe wants you to reach the top. How do you avoid that and why are you alive?

@Henry Wagner It's wasn't meant that it's burden. It means that every living being needs to strive for something or else there will be no tomorrow. If you reach at the top and cease to continue striving, then you are dead or at least no more motivation to stay alive in the current flow of motion.

I got really emotional watching this video. The processes of the universe, of life and of evolution are breathtakingly beautiful. The universe itself is meaningless, but the fact that we get to experience it helps give our existence meaning. Thank you guys so much for it. On a side note, there is a mistake in the cladogram shown at 6:12 because it shows fungi splitting from animals before they splits from plants. Fungi are actually our closes evolutionary relatives, so our lineages were the last to split. It should go like: l---Plants --l l l--------l----Fungi l----Animals

@No Simpathy regarding your first paragraph: The nice thing about science is that you don't have to believe it. It is (the closest thing we have to) the truth whether you like it or not And regarding the second one: You can find evidence for anything, but an idea only constitutes a theory if: a.The evidence is solid; b.If it is attacked and stands long enough for the scientific community to regard it as such (see Popper's Falsifiability principle)
No Simpathy
No Simpathy Vor Monat
@Mario Freitas if you believe that, that's fine, is there some truth to it? most likely but there is no way to concretely come to those conclusions of things that happened far before our existence here. And regarding the second part I had to look it up and ok a theory is basically an explanation for a observation with greater likely hood of truth than a hypothesis. But either way if you look hard enough you can find evidence to support almost anything
Mario Freitas
Mario Freitas Vor Monat
@No Simpathy I'm a biologist. Take my word for it, these are facts. On a side note, in science a theory is an idea supported by evidence and facts. Evolution, for example, is a theory and is a fact. Something you don't yet have evidence of is a hypothesis.

Do you think life began multiple times? That the first couple of times didn't last because they couldn't divide into more cells, or that they couldn't create enough energy to keep them alive? Do you think that in one of the later times in which life began, it was only then that it could last and evolve?

I think as we go out into the universe and start discovering self-replicating molecules, or micro-structures that could potentially be considered "organisms," the example of the mitochondria might become the litmus test for saying what's alive and what isn't. Only if the cell is coexisting with another type of cell inside of it - working to mutual benefit - can the thing be considered 'alive,' by our comprehension.

I enjoy these videos very much. I would like to see one illustrating actual observations of how life can come from non-life. We can observe how life becomes non-living (dies). This video readily admits that "unsettlingly, the universe wants us to reach the top (meaning die)." I interpret "wants us" to mean is working to kill us; or there are many more mechanisms that can readily kill us, as opposed to helping us stay alive. However, As far as I know, actually observing or replicating the creation of life from non-life is still an unprovable mystery that obviously did happen at least once, but no one has actually observed and conclusively replicated the mechanics. For all of our scientific knowledge, no one can create even one blade of grass, or a custom designed living cell from non-living parts. Not that very smart people haven't tried.

Great video. I have a few questions, hopefully someone smarter than me can help in answering this. #1 When the "original cell" ate the the other cell and became a host for that cell... didn't that host cell have to reproduce an offspring to keep that genetic change going via Evolution? What are the odds of the offspring also displaying this change?? And what would this fall under?? Would this be a "mutation category"?? Swallowing another cell and allowing it to live inside of you to the point it becomes part of you.. ?? #2 Also, what are the odds of this cell surviving when eating a whole cell and allowing it to live inside of itself? Maybe I just don't understand how the cell's digestive system works to allow another living cell to survive inside of it. Any answers would be greatly appreciated!
The Hipster Hรกmster
@Odd Fellow Remember that you yourself are the proof that it's posible, if not that means that cells can also be created already multicellular from the beginning. In my opinion that would be even more unlikely simple system tend to become more complex over time. Maybe that's another possible theory? Great talk have a nice day ๐Ÿ‘‹
Odd Fellow
Odd Fellow Vor 3 Monate
@The Hipster Hรกmster Well, I don't have a solid theory myself, I'm more trying to make sense and understand this theory more clearly. Thanks for all the info!
The Hipster Hรกmster
@Odd Fellow I mean it is extremely extremely rare, let's say so rare that it's basically a 0% chance. but that doesn't mean imposible. Let's say there is a 100 billion in 1 posiblities for a cell to host a second cell. It looks like an impossibility because of the chances of happening. It's a 0.000000000000001% chance. But if you do 100 billion attempts theoricaly you should have 1 cell that was able to do just that. Now lest say you do 1 trillion attempts. Now they are 10 cells able to host a second cell. Now do 100 trillion attempts know you have 10,000 cells with that same capability. A million trillion attempt are 10,000,000 cells. And so on. Numbers can be misleading sometimes. The probability looks super low but if you factor the years it took to evolve it sorta makes sense. Remember that cell life is much faster than human you can have like 500 generations of the same cell in under a month. From 1 to 2... to 24,000,000 in less than month. Growing exponentially. Every day I don't know if am explaining it clearly enough, if you don't understand please tell me or explain me your own theory if you like.๐Ÿ˜ƒ
Odd Fellow
Odd Fellow Vor 3 Monate
@The Hipster Hรกmster I see.... then perhaps I'm not understanding the concept of the cell surviving inside the host cell properly. In my mind, I saw that scenario (a cell swallowing another, surviving and hosting the second cell) extremely rare, and the only opportunity for it to evolve from there was for that cell to survive and split in to two, creating another cell with the exact same structure . I didn't see it as a genetic mutation yet, that's why I hesitate to use that word, because.... I don't understand how the cell passes on that trait of hosting another cell so instantly. I hear what you're saying about it taking numerous tries to finally get it right, but wouldn't it need to be right the first time since a cell surviving inside a host was an extremely rare thing to start with? Or was that scenario more common than this video and others make it seem?
The Hipster Hรกmster
@Odd Fellow think of it as computer code. The first generation doesn't work for x or y reason . But that doesn't mean that will never work. lets say it takes 101023948202023 generations of cells to completely mutate and become a true multicellular organism. The other differences is that a generation of cells takes about 1 hour. So billions of billions of tries where made until they got it just correctly. What I'm trying to say is that it possible took a very big amount of tries before they where able to as you say "mutate" in the correct way. To me this is the most convincing way to explain how organisms have evolved since the origin of time.

Dankman9
Dankman9 Vor 2 years
@Chavez Harding the original poster said "Every Kurzgesagt video: -Facts -Scares you -Then calms you down" So I was just pointing out that not everything in the video was factual. My main argument was based on the universe not having intent, we agree there. We also had the side argument that if you were treating the universe as if it had intent, whether or not it was trying to kill you, or life in general. I still argue that it's not. In that argument it doesn't matter how much of the universe is inhospitable, it confines you and life to the part that is, so it's clearly not trying to kill you, or life in general. The total amount of planets or space that won't support life is irrelevant because the universe is not subjecting you to those places, it's protecting you from them. There really shouldn't be any argument with those points either. Logic is also on my side here. The final part of the argument, entropy. This part of the argument also assumes the universe has intent. I think this is your best argument but I still don't think it makes sense. No matter what the universe does, anything that is alive will die. You can't really give the universe credit for trying to kill you if it's just letting you live your life. Also giving the universe credit for entropy as a weapon to kill you or life in general, seems like a huge stretch that you haven't supported. I don't think that makes sense. And even if you blame it for killing individuals, those deaths support more life. The circle of life continues. Eventually the universe may not support life at all, but that I think is a bit outside the scope of our argument and we don't really know for sure. I hope that cleared things up a bit more. Ok on to respiration, that's right you mentioned that before. I don't remember what he said in the video exactly but I think I would agree that's non factual. There are similarities but combustion doesn't seem like the most accurate way to describe it.

@Dankman9 Ah I see now what you're saying. You could argue that. The universe as itself doesn't have will. I typed "trying" out of habit. Really we're only arguing personification here. You arguments threw me for a loop. I thought you were arguing that the universe is hostile toward life. I did not know that you were arguing whether the universe has "intent" or not. To be honest I still think the statement is true although not literal. Sure the universe literally speaking does not want anything. Physics just follows a predictable path and that path happens to be against life. Hence if the universe was a person it would definitely be trying to kill you. That's the point of personification. Although it should not be in a video that's meant to be expository which is where the confusion is coming from. There aren't supposed to be any figures of speech. Anyway I still think the complaint wasn't really warranted? It was just pedantic nothing more? I'm sure people get what the narrator was saying. But you were right I have not been listening I was doing too many things at once. Still don't get why you brought up life on earth though. Even though life thrives on earth it will succumb to entropy. Reproduction counteracts this but it can't last forever. Anyway the next non factual statement was describing respiration as a "combustion reaction". I don't agree. It works more like a battery.

@Chavez Harding - "it is trying to kill us anthropmising it or not." That is what you said. At this point I'm not sure you are even reading my statements in their entirety. Saying the universe is "trying" to do anything, is anthropomorphizing the universe. Without doing that, no matter what you are arguing about physics, or the inhospitality of most of the universe, the universe doesn't "want" anything, it isn't "trying" anything. Living things die eventually no matter what the universe does, that doesn't support the argument that the universe is trying to kill you. I think you are also conflating the arguments. One living thing dying does nothing to disprove that life in general thrives on earth. If all you think I've been doing is yelling fallacy you haven't been paying attention. And yes several of your comments have made it seem like you do actually agree that the statement "the universe wants you dead" is not a factual statement. Including your statement "that is definitely not a factual statement". Anyway, I've thoroughly explained why that statement isn't true. Let's move on to the next non factual statement. I'm done explaining this one. Cheers.

What if we solely exist to increase entropy? Living organisms, especially when they make it so far as we have and build a civilization, are creating WAY more entropy WAY faster then any non-living matter. Therefore the universe might be "interested" in having living creatures, because its moving faster to entropy than without living creatures. The reason for live is causing entropy.

I always found that this might be one of the reasons complex and intelligent life does not exist on earth because the event that caused mitochondria to be absorbed could be an extremely low odds event that also requires multiple other extremely low odds events to happen. For all we know we did a grand slam on the lottery of rare events or what happened could be common and we just ain't hearing the other species.

5:40 I truly believe that this the great filter. I believe life may exist in abundance in the universe but can only achieve at max simple one-celled organisms at best probably surviving through a simple process such as glycolysis But somehow, someway, two single celled organisms became one, and life just exploded from there. We have no idea how this happened, but that it happened is extremely clear. I believe we may actually be the first sentient life, at least in our galaxy, to have grown from dead matter to single celled organisms, to multicellular beings capable of evolving a consciousness. Just like we don't know how the first nucleic acids began replicating themselves into better and better generations, but we know it happened. We have no idea how the primordial mitochondria and primordial single cell fused, but we know it happened, we know that the primordial mitochondria's DNA almost "decided" to die, in order to ensure its own DNA's survival. Somehow, dying was beneficial. If I'm inaccurate, someone please correct me.

The chemical process of converting one larger molecules into two smaller ones is called analysis. The chemical process of converting two smaller molecules into one larger one is called synthesis. To achieve this, there needs to be something energetic causing it. Like electricity. You can split salt into sodium and chlorine by basically electrocuting it. This is called electrolysis. Merging two molecules with electricity is called electrosynthesis. You may see where I'm going with this Electricity is not the only thing that can achieve this, electromagnetic radiation can two, electromagnetism is a force carried by photons. Splitting a molecule with a photon is called photolysis. Merging two molecules using light is called Photon + Synthesis Photosynthesis That is the origin of the name. The two major molecules being massively converted here are Carbon Dioxide (CO2) and Dihydrogen monoxide (Or just water, I'm sorry it's just to funny to say it like that). These contain all the atoms required to make glucose (C6H12O6). But they will only merge under the influence of photons, that's the photosynthesis part. The chemical formula of this reaction is Photons 6CO2 + 6H2O => C6H12O6 +6O2

Since a glucose molecule has about 100x more energy than an ATP molecule, and cellular respiration produces 36-38 ATP molecules per glucose, that means 62-64% of what you eat is lost.

I used to have a book called "Energy and the Evolution of Life" (before it was lost in a move) and...well, it was full of math that I couldn't understand...but it seemed to propose the idea that life and evolution could be understood as the flow of energy, storage of energy, and it's interplay with energy...not in a woo-woo way, but in a similar way than this very video. Wish I was smart and educated enough to understand the math in the book so I know what the hell the author was talking about.
