The Digital Life Experiment - String Theory and Minecraft
String theory and Minecraft

Follow by Email
The Digital Life Experiment is a hypothetical experiment, whose purpose is to compare our observations about reality with observations that a digitally evolved intelligence would form about their own reality. Like Schrödinger's cat, the experiment doesn't actually need to be carried out in order to be effective. Its goal is simply imagine the implications of living in a digital universe, and what that would mean for us.

nordic fatcheese : You might be Vsauce4 at some point man! That was really good! 

Matthew Singleton : Now hold on just a second. If life was a game, why can't I buy free coffee DLC?

Will Mahaffey : so wait- what youre saying is that we can use minecraft to be the god of our own universes?

Charles Jr. Pike : just as people have made computers in Minecraft that use binary, imagine if we learned how to code in "string theory script".

Deactivated : The mysteries of the universe, solved by a Minecraft player. This is why I subscribed <3

Rodrigo N. : It just annoys me the idea of i won't be living by the time we discover a decent amount of the universe/universes, or more than that. It's known that there's infinite things to discover now, and thinking of that just makes me anxious, it feels like we didn't discover anything so far, just our solar system and another things around... having another planets, galaxys, etc, that we cannot go to, that are significantly close to us, it makes me feel so tiny, and empty too ! Because, obviously, every human being has that anxiety, that feeling when you wanna know everything about something. How much time would humans have to wait to have another Einstein or super smart physicist (he's the only one i know so far that has been relevant) that discovers some shocking thing or device that will change it all.. and will he make it all clear? I don't think so. So that, plus the fact that that guy will die, and we will have to wait to another one, it just sums so much years that i feel like saying 200 years it's not enough to get a relevant resault for humanity, having the humans that feeling of anxiety and "i want to know everything about it" feel. All of this, i'm pretty sure, it will annoy some of you and think all i just say is stupid lol, but it's the way i feel. PD: Nah, we're not alone in the universe... (sorry for the english though, here, have a potato * potato* )

Jay Liu : The universe was created last Thursday

iamanai : Oddly enough I'm writing a novel about a "Digital Life Experiment". Except that the book takes place INSIDE the experiment itself, with the characters being computer programs named "Pixels" living in a virtual world. They discover this and break out.

Playzon : I really love these videos. These are concepts that I already "understand" but the perspective makes them so much easier to do the thought experiments instead of just thinking about the basics. Thanks for this project you do.

James Batten : Your videos are always great and interesting, but I have a love hate situation I always end u feeling depressed after them. Its nothing against you, it just reminds me I'm nothing special....I'm nothing

lucy hayward : string theory is frickin depressing

Skoldiber : As always, i dont understand 90% of what you said, and yet i still loved watching it, probably for that very reason :D

Nuance : I'm so glad I didn't leave your channel when you said you would stop making Minecraft videos. Cause this is the type of Minecraft video i would like to see more than anything else.

Yonkage : Consider the following. It's fairly well assumed that, eventually, humans will produce a virtual reality world that is indistinguishable from the real one, that you can enter like a dream and never know the difference. At the current rate of technological expansion, it probably won't even be very long before this capability is reached — maybe a hundred years or less. The problem is this. The universe is already pretty old, but compared to how much longer it's going to be around before reaching Heat Death it's nothing at all. A few seconds have passed compared to a day; a few inches have been traversed compared to a mile. Supposing that humans will be around for the entire remaining life of the universe, which they probably will if they become powerful enough to make perfect virtual reality worlds, it is unlikely that we'd be here and now. It's much more likely, statistically speaking, that we would be alive in that massive block of time that is the future, instead of the tiny one that is the past. Because of this, mathematically speaking, we're much more likely to ALREADY BE INSIDE a virtual reality world, than we are to be in the real one.

Anonymous Name : Hm.... I so. Want to make a mod for that, to make a self evolving code on minecraft

JA7ja : Minecraft yet again shows us that its relative simplicity can be used to understand even the most complex of topics

defective guardian : if you ended up making these little mini series into hour long shows I'd watch every minute of it.

Dylansgames : Would this mod be literally possible to create? I think it would be an awesome experiment if it were possible.

Turch Gerber : Never watched you before now your in my top 3 youtubers


CYRRYANC97 : This is actually a very interesting an legitimate theory. Currently with our computers we can simulate a electron of an atom. Maybe down the road we can simulate a full atom. Maybe a little later we can simulate and entire cell. Maybe later we can simulate an organism. Then maybe a mammal, then maybe a planet with life, then maybe an entire universe. We can be living in a simulation made by beings right now. This theory has not yet been disproved and is actually what Elon Musk believes in.

EMBEAM : This video inspired my entire commandblock knowledge, thank you slumwack

Nero TN : I actually learned something. Not only that but the video was well put together, SUB

Freak80MC : So Spum, say we simulate a universe on a supercomputer and intelligent beings evolve within that simulation. Would those beings at any point ever be able to interact and effect the computer running them? (Like turning off the supercomputer or changing the rules of their own simulation) This is something I have been thinking about for a while and you may have a little bit more knowledge to help answer this! 



Mr. Gamer : I love these videos keep it up they are amazing

Unlocked : You say that the minecraft and real life analogy isn't perfect because we can't be on a hard drive. That would seem to make sense... but do we have any way of knowing we aren't? If we could write an intelligent minecraft program like the one you describe in which members of the world can actually think, it's far more likely that we are also just some sort of computer simulation than that we are the the original beings. If the minecraft mobs could become as smart as us, they would also be able to make a similar simulation... but wouldn't they think they were the originals too? The next step out could be just as different from us as our universe is from minecraft. Certainly different, but still somewhat similar.

Doggs4Life : us: hey there code for the universe higher lifeforms on the computer: there on to us, THERE ON TO US!!!

A Pig : You just blew my carrot-loving mind

akumabito2008 : It's turtles all the way down...

Nathaniel Park : why doesn't this guy have more subscribers???

TheMCAstronaut : The only problem I have with this theory is that if we lived in a digital universe, the values of pi or the square root of 2 could not be irrational, infinite strings of digits. They'd have to end- and our programmers would have to know where they end. Vsauce explains this very well.

olives003 : on par with vsauce for reals

Cristian Salinas : God I love these videos UUUUGGGHHH There is so much work and thought and damn these are good

H0pestart3r : You know, Spumwack, I reckon that you make more of these videos. I do wonder how on earth were you able to squeeze in knowledge about science in your videos, like you applied what you learned in college or something. I think we're more than just one universe.....there could be even more than what we think, even if our perceptions are very much limited. It's like we're but a tiny star of life in such a vast mass of outer space....but the universe is also coexisting with millions of others...perhaps we never knew on what have become of those other worlds...

GoldenTV3 : It's funny how this video that is about minecraft made me think more and gave a better explanation than any conspiracy video I've seen.

Doggs4Life : Minecraft is the closest to shoing our world google earth vr: bruh

deerfan : Spumwack, I live for these universe videos of yours.

Herbivore The Carnivore : "String theory and Minecraft"

Inferno Gear : Mod for Zombie Growing! Yes Yes Yes! Good idea on that mod idea Spum.I would love that only sped up made!

Ruby : When you go from acknowledging the universe's system and how it works, to making overwatch top 5s

Random Cannon : 1:45 So, where do I get the mods then?

Anthony Rocci : Sou, could you use these Dark Matter "Gravitons" to travel between dimensions?

GrimKriegor : I love these videos sir. You quickly became one of my top 5 youtubers. Keep up the amazing work!

donnysmurf : I enjoy your thoughts and videos as much as I enjoyed those of Carl Sagan. Truely thought provking, exciting, brilliant stuff.

GoldenTV3 : The Black Mirror, White Christmas episode is a great look into this theory. Especially the code part.

Vincent Li : This honestly blew my mind. I love it! KEEP IT UP, SPUM!

Owen Loh : wow....minecraft
