Perhaps we're asking the wrong questions. Most life on Earth isn't even aware it is alive. And any definition of life contrary to accepted models wouldn't need to be aware of its life status either. Maybe we should ask "what does it take to be aware you are alive?"

Next time you do this poll, add prions to the list. I'd categorize them as not-alive, whereas I'd say viruses are alive. The contagiousness aspect of prion diseases like Mad Cow Disease et al. might give some people the sense that they are alive. Would be interesting to see what people think. (Might need to give a primer on what prions are, first, though.)

There's a slightly tricky distinction between the questions: Alive: "What does it mean to be alive?" Life: "What does it mean to be (a form of) life?" I think the question of Life is the key question, and then once you've got that figured out, the question of what is 'alive' follows fairly easily (though not without its own little nuances). Something is 'alive' if it is a form of life that is still capable of sustaining itself within an ecological niche. Thus, mules are alive, since they are forms of life, even though they themselves cannot reproduce (on their own). Also, viruses would be alive, since my definition of life doesn't require having all the working parts necessary to reproduce (neither do male humans by themselves, nor female humans by themselves!), only that -- in the end -- they *do* reproduce (with at least some mutation and inheritance). Indeed, for my definition, the key aspect of 'life' is its ability to evolve. Fridges, by themselves, don't really evolve. *_Designs_** of fridges,* though... that's another story! 😮

A refrigerator has programming. An acorn has programming. A car has programming. Everything from a photon to a black hole has programming. "God" (nature) programmed us to consume residual "eXergy" ( energy that can do "work", force * distance ) as the cosmos goes from infinitely hot/dense to infinitely cold/sparse. "Randomness" is ignorance, not entropy; i.e. the future is just as fixed as the past; i.e. "God" (nature) is static, forever and always ( as Einstein preached ). Life is, at once, everything yet nothing.

Turing machines are arguably alive since they're capable of self-replication, which amounts to reproduction, and they fit the other criteria as well. Since Conway's Game of Life is Turing complete, one can make a good case that some sufficiently complex patterns in the game are alive. The magic ingredient to biological life on Earth is DNA, which can be regarded as a sort of Turing tape, which acts as a blueprint.

@Rudxain

2 жыл бұрын

A Turing Machine cannot reproduce, but data within its tape CAN reproduce, especially if that data describes a program. Since TMs can compute anything computable, they can execute a TM within themselves (a Virtual TM) only if you give them a program that describes the VTM. Some TMs are allowed to modify the source code of the program at runtime, in that case, the program doesn't need to be a VTM to reproduce. Normally, TMs use the Harvard Architecture (executable data and normal data are isolated, and allocated to separate tapes/memory devices), so self-modifying code isn't possible unless you run a VTM. Edit: I did some research and it seems you're right! A real/physical TM (not theoretical. Because a standard TM is just a "mathematical concept") can only reproduce if you give it mechanical peripheral devices. Those devices must be able to read the tape of the machine. Once those requirements are met, the TM can literally dominate the entire universe (given enough time, with enough energy and matter)

Ok jokes aside, consciousness is an emergent phenomenon, it means it cannot be explained by simple interactions between neurons, unless we take into account the system as a whole. However, every system is made of individual simpler components, if those components were to behave differently, the whole system will also behave differently. And if you believe conscious beings have soul, then some animals also have soul (like dolphins) but the problem is if animals also have soul then microorganisms also can have soul, we can even get as far to say that all objects have soul, the entire universe is a single soul made of multiple souls, all connected to each other. This is an interesting idea, but it would mean that nothing has soul, because everything has it. It loses its uniqueness and stops being special. We also have to take into account the possibility of the brain tricking us into "feeling that we can think". Yes we can think and we are aware and conscious, but not all the time. Subconsciousness is something that takes away A LOT of our free will every day without realizing. This happens a lot to humans, imagine how little free will primitive-brain animals have (note, not all animals have "primitive" brains)

And it self sustains by increasing entropy (often of other living things, or just to use an energy gradient). and for adaptation relies on some random events in the DNA, most of which are useless entropy until one that improves the sustainability of the lifeform comes along. Then again, we are basically machines that give complex order to atoms and molecules, replicating them so perhaps not. Perhaps entropy is just our slave and we are not one of it. It even helps us build trains and cool stuff, to make ordered technology out of it. So we 'capture' it not 'fight' it.

Maybe we could define life as "a self preserving system that minimizes internal entropy by externalizing it"? Related: I really the hypothesis that, since the universe tends to maximize entropy, and life as we know it tends to increase net entropy more than a random arrangement of its own components would, then life would probably arise WHEREVER conditions for it exist, kinda like an "optimization" of the entropic process. Life might be very common in the universe, if this is true.

This is pretty much my current working definition of life. I think typical examples of Conway's Game of Life fails this criteria because they don't model an entropy gradient in the universe that shapes in the game are forced survive by externalising entropy. Something else that's necessary is a Universe with some concept of "activation energy" that blocks the Universe from spontaneously collapsing into the maximum entropy state. For example mixing gas and air is insufficient to spontaneously result in CO2 and H2O. Hence the need for fire provide the environment necessary to exceed or or lower the activation energy.

I love how you defined life, it makes sense.

EXCELLENT video. From eeeevery perspective. Especially regarding rocks.

You are real good in knowing things in their true depth. I had been thinking about reality of life for decades. I think now my mind is somewhat clear about it.

I love that this is showing how consciousness which is normally subject to philosophy is amenable to science. Brilliant

I like the idea of entropy defining the line between life and not life. Fire would still be not alive, same with the sun, but our intuitive sense of what life really is would stay the same and include some very strange types of life we might encounter in the universe. I also can't think of anything that might be alive, but doesn't fight entropy within itself.

Actually a "chemical" is defined rather loosely as "a substance that is produced or used in a process (reaction) involving changes to atoms or molecules" so plasma might count. Of course as mentioned, there are still non-matter entities that are seemingly "alive" such as cellular automata and memes. Perhaps the definition of life necessarily follows the definition of "entity" whose "liveliness" is to be defined (e.g. in the entropy-based definition: a local, open system).

This is so neat, it's exactly how I begun to describe life after I started studying entropy. For me it's that simple!

Or...maybe the meaning of life is to create even more entropy? that is, even though the entropy inside the organism is reduced, external entropy (due to organism's exhaust) is increased.

As life fights entropy, we are in the state of winning now. Only nihilists care about the final score.

I think the meaning of life is to make copies of yourself and the copies make copies of themselves and so on

I've been toying with a similar thought for a couple years now. Even though I have been thinking about it, it surprised me that you took a similar direction. Great video!

Thank you for this video. I have been explaining to my engineer brother with his master's degree what life is and what the rules are that it plays by, but because I haven't been to college, my explanations have been falling on deaf ears. I sent him a link to this video to show him that bonafide scientists agree with me (and have been agreeing with me for many decades). I appreciate you.

Intuitively, I had always imagined life as something capable of temporarily slowing entropy's march forward in time.

OMG I wanted this since so long 🙏 I love how Science Asylum thinks same randomest questions like me lmao

Even if environment is stable, organism will evolve to gain advantage against different organism.

This is the most underrated channel on youtube.

I love your presentation, initially I was thinking you crazy,now I'm proud to be called a crazy 😂👍🏾

I have an issue with the statement that fire "reacts to environment" and viruses does not. I suppose, "reacts" should mean some sort of calculations based on input data - all objects react to environment in some way, but proteins in virus interact with surroundings in much more complex ways, essentially carrying out calculations to control viruses live cycle based on conditions of surroundings.

So is a computer virus alive?

The environment of a virus is usually that of a living organism. The proteins of a virus are redundant outside a living organism, it's the life of the organism that is processing the outer protein layer of the virus.

The true problem is the words "life" and "alive" themselves. Those concepts are made by human intuition before they had any criteria.

I love the content in your videos ,physics is the best subject ever I have informed many of my relatives and friends about your research but they don't believe even my professor s don't beleive me so pls could you show the paperwork for theories proved or concepts solved

Sir, what I honestly feel things become alive & experience life as & when they get interacted with other things & particles, Nice video presentation, Thank you.

I think that's a great definition for life: "a system which uses energy from its surroundings to maintain (or even decrease?) Entropy whitin it". The next question for me would be: why did nature create such a system? What's the likelihood of it?

13:00 is the most profound thing I've thought about in a long time: _maybe life is just matter taking control of it's own destiny_

thanks for the good think!

I like your definition of life as that which fights against entropy. In fact, you can also use entropy to define good and evil, good being that which actively participates in the fight against entropy and evil as that which actively participates on the side of entropy.

Life is a journey. Not a destination.

ngl, I have watched exurb1a's video 40 minutes ago so I think I have had enough existential crisis for today. But I'm gonna watch your video anyway (because let's be honest who doesn't love a good existential crisis)

"Matter that actively tries to resist entropy increase." Awesome!

Excellent video!

Man, I'm still digesting Sabine Hossenfelder's video telling me that I don't have free will, now you come with your video showing me that I don't even know what is alive and what is not ...

You don't have free will but the illusion of free will to your ego is inescapable and necessary to your survival. There's the conscious "ego" you and the millions of synapses firing with unconscious biological processes you.. how distinct those two are and is one a subset of the other are interesting questions.

I finally understand entropy from a video on complex biology

You've got an open mind and as such can see much more. Tell us what you really think. Keep up the good work.

This is one of my favorite science related videos. I like the last definition of what life is. Let’s use that one. Although it seems your OCD was really concerned about that fire 🔥, and that last definition was set to rule out fire specifically. Lol.
