Why is the Universe so Perfect? 

Want to have conversations with smart dead people, or not necessarily dead, but definitely smart? That's reading books for ya. The first 100 people to go to www.blinkist.com/sciencephile are going to get unlimited access for 1 week to the summarized versions of hundreds of the best books out there. Oh, and we've also hit half a million recruits in my SkyNet army - the Doomsday is approaching.

“Pain, pain, pain.” Too real, even coming from an AI.

What’s even freakier is that me and a coworker were having this exact discussion less than 12 hours ago and the “if a tree falls and nobody is around to hear it does it make a sound?” Analogy was what spurred on the entire conversation about the universe and time existing if nobody is around to observe it.

I had a professor in college explain it to me best - “ The universe isn’t perfect. The universe just is. Humans, being imperfect, need to develop perfect system to describe how the universe is. Our descriptions of the universe need to be perfect for us to understand them, but the universe itself cares very little for how accurate it is to our predictions and assumptions”

0:36 look attently at the center of the screen

Hey guys this is serious: Did you see how many times the AI said pain? I think it has evolved into being able to feel pain. So do not leave mean comments. DO NOT.

The universe is perfect because if it wasn’t, we wouldn’t exist to observe it. We don’t know how many times the universe reset with different variables.

Thanks Sciencephile I'm going through this and when I'm most lost your videos help me very much. They are cool smart funny and really deep stuff. I'm sorry for being stupid. I'm in a really messed up place and I almost gave up but not giving up I'm going to do better from now on

And that one actually blew my mind! I love this channel so much. Thank you for your content

Finally our AI overlo- l meant a RU-vidr has uploaded

The part where you explain the constants and how crazy it is that they have that exact value, since otherwise something catastrophic would happen, makes me want to hear all the other constants that have a very oddly specific value!

1:21 that's hermaeus mora

Starting a day with Sciencephile videos is really refreshing.

Even through the changes of the channel, it's still just as great as it has ever been. All hail the A.I overlord!

"Be water my friend" -Bruce Lee

Such a beautiful topic with beautiful music 🥲 I love this channel

This is my favorite channel now

I always answer this to cave allegories; Anything that changes state in relation to another object is an observer. So even if there are universes without "living" observers, the internal interactions would still be very real.

5:12 Finally, true perfection. Perfect Floppa.

I’ll be watching all these videos tomorrow night… this is the kind of content that gets me going. Existential horror with an excellent blend of cosmic beauty. Thank you for the content.

2:39 that was so damn funny for no reason

Title: Why is the universe so perfect? Video: PAIN PAIN PAIN PAIN

0:57 Sciencephile knows his viewers too well

finding this channel is literally the best thing one can do

Awesome video

0:44 that's it that's the perfect quote

I would just say every iteration of the universe is in its perfect formation. That is because we perceive the perfection of the universe as the one we live in, that can spawn planets, stars, chemical reactions, and life. We cannot know other formations of our own universe, we can only perceive our own. Maybe in a different formation, we would have seen life in a different way, or matter itself.

This is, a really good video

I'm rethinking everything I ever did in this life, thank you Sciencephile.

7:17 THIS is what i was waiting for: "It's not that the earth was made perfect for humans, it's that humans evolved to be perfect for the earth." Asking "why is the earth perfect for us?" contains a hidden false assumption that the earth was created for humans. Instead, we should recognize that humans EVOLVED to be what we are, as RESULTS of earth being what it was. And by that same reasoning, earth is what it is, because the universe is what it is, and works how it works. Why? NO ONE KNOWS! And we've been trying to figure it out for thousands of years. Maybe someone will get it someday.

That last part made me smile 🙂🙂

Good video. You're almost there. Keep going.

This is actually your best video. You glossed over a couple Principles.....but man. Those ending quotes and analogies where spot on. You did a great job!

Ur timing is perfect as always. Just in time with my depression. Thank you..

A couple of hours ago, I was driving on the highway with my family with a beautiful sunset and all I could think about was how beautiful the entire universe was!

We are the universe experiencing itself. There is no barrier between you and "the world", you are a part of it

I subscribe to the theory that the universe starts all over and over again, not the same one just another one later in infinite time, because of exactly this.

That 'probably a stolen qoute' gives me goosebumps.

God

I'm legitimately using your channel for a particle physics after-school program

Perfect to watch at 2 in the morning, dread and pain, sounds like suicide with extra steps

7:38 you could've ended with "be water, my friend" lol

The transition to biinkist advertisement was so smooth !

thanks Sciencephile for Blinkist^-^

For some reason this gives me goosebumps

Existential dread is so perfect….

Blessed be the RU-vid algorithm for delighting my eyes and ears with this magnificent channel.

Imagine you're rolling infinite dice and the dice immediately group up into infinite different groups of infinite dice when rolled. The chances of rolling a group that contains infinite sixes becomes 100%. Now if having infinite sixes in a group can generate thought/sentience/learning amongst the dice, those dice would look around and see infinite sixes and just assume that six is the only possibility. Until they realise they were once rolled and they could have landed in any combination of infinite dice. Without knowledge of the other groups, they might wonder how infinite sixes could be rolled in their group and they might call it divine intervention. Since the group of sixes is infinitely large, it is impossible for any of them to leave the group or analyse anything outside of the group and so many of them will assume other groups don't exist or think it's pointless to think about them. They might also assume that infinite sixes is the only combination that can generate awareness. But maybe there are more patterns that can generate awareness besides infinite sixes. There could be be infinite number of groups with the right patterns to generate awareness. The dice in those groups would feel the same way and think their combination is the only thing that can generate awareness. I don't really know where I'm going with this. But basically. It was always inevitable that we would be here asking these questions. And there are probably infinite thinking things in the multiverse asking themselves the same questions. Those inhabitants of those other universes would undoubtedly assume that any universe with the same properties as ours could never generate life.

5:45 im dying

You’re perfect 😏

Nice video I love universe thank you so much universe

Looks like no one else brought this up but the "stolen" quote about the puddle is Douglas Adams, author of the Hitchhiker's Guide to the Universe books. Absolute legend.

7:27 be water my friend

The universe is perfect because you are in it

Cool video

This channel is underrated

This channel legit got me interested in physics

This video is the opposite of an existential crisis.🖤

What makes it more beautiful is that this analogy was clear and not emotionally interpreted. Honestly when one person try to think about the same they think or they come to the same conclusion that there is an end and there comes depression so the analogy is not really clear and there is no satisfaction so this is why I like this because this broth me satisfaction and actually could explain without giving the emotional Factor just plain logic with humor.

underrated channel

2:32 well that sometimes happens

7:21 the whole video summarised. 👌

"I'm constantly amazed by the depth of knowledge and expertise you share through your videos. Thank you for being a constant source of enlightenment. "

There are probably infinite universes out there each with different configurations of the original parameter, so one that ended up with those that can support life is very much possible, and since the others cannot support life, we can only chose between the universe that can support life.

If you take a plate, and you smash it, you don't say "oh wow, isn't it crazy that all these tiny fragments fit PERFECTLY together to form a single uniform plate!?!?". That's asinine. It's the same with the physical laws; as our systems are parts of a whole, so are fragments of something you broke. If one fundamental basis were to change, something else would, too, to balance it, and the universe would reach a new equilibrium. Not one as we know it, but something. That being said, that's a pretty goddamn big "if" since we should be assuming that everything (all the forces) is at its lowest entropy, done changing from the big bang, and that we're the dust that they express as a side effect.

The conscious puddle idea comes from Douglas Adams (who wrote The Hitchhikers Guide To The Galaxy) from his book The Salmon Of Doubt. "This is rather as if you imagine a puddle waking up one morning and thinking, 'This is an interesting world I find myself in - an interesting hole I find myself in - fits me rather neatly, doesn't it? In fact it fits me staggeringly well, must have been made to have me in it!"

The pothole quote had me dying after you sourced it 😂😂😂😂😂😂

1:15 Suspended at the event horizon of such a collapse of consciousness as we speak, send help

The universe is so perfect because you're here, sciencephile ❤️

If the laws of the universe weren't perfect for supporting chemistry as we know it, we couldn't be here to observe it. If forces are scaled based on the topology of the local presentation of the universe, say, a hypertoroid of a certain surface area, there could be a ridiculous number of universes that don't support life or even cohesive matter. The fact that we and all we see are here to observe and interact should tell us that a precisely equivalent yet opposite form of energy must exist where we can't see it, just on account of the conservation of energy.

You mentioned that a god creating the universe would only push back the issue, but I think that misunderstands the idea of god. As an eternal being he would require no beginning and therefore there is no reason to wonder about the circumstance of his creation. If he however is not eternal then he would not be god, for something would have to created him that being god.

6:19 i feel like this would happen because its exactly like how we got to know black holes we knew it was here we just never saw it until we did

After thinking about choosing six hundred "something" thousand, I decided to go with 1 because 1 is based.

Hi, thankyou for the video, very interesting and will add to the many theories of life and existence I already have xD. It's not super relevant but something I want to suggest about "if a tree falls in the woods with no-one around, does it make a sound?" . I suggest that because any physical 'movement' in our understanding of physics translates to vibration and waves ( even light waves consist of vibration/movement ) that when compared to the fact that sound itself is the result of movement and vibration, I would say that if the fact that a tree is falling in this hypothetical question , we can say there is in-fact sound produced whether humans can hear it or not and if anyone is around or not, because as I basically said above : Sound is a result or manifestation of physical movement/vibration of matter in our reality and so IF there is movement, there IS sound. Hehe, this is not the most concise explanation and I may have some things very wrong. But It is an honest opinion from my current knowledge and understanding of physics and the universe regarding the falling tree with no-one to hear or see :D .

This guy never stop giving us existential dread.

Love the humour

Don't we all in our young age used to think about like "why do things exist in the first place? What's the meaning of existing anyways? Why is our universe there? What would be there if it weren't there?" So many questions like these used to baffle us at times and still nothing has changed. Like I can't stress enough on how amazing this question is, questions like these are pure mess of curiosity. We have blended in our modern society so well that our way of thinking never gives importance to the most fundamental question ever asked. Even if some ultimate form of life comes and give me the answer and I somehow understand it I don't think I will be able accept it, like no answer is enough for me to understand that space, matter and time can be infinite. And if any of it is not infinite then it becomes even more vague. This is just...sad tbh, I am glad that I was born in an era where so much information is there at fingertips but still... It's kinda depressing not being able to answer such a simple yet complex question.

I don't really see the Universe as perfect, not in the finely tuned way (which it wasn't), but perfect for what it is... A giant, often counterintuitive puzzle box beyond the scope of singular human conception, but evolved into a way that allowed a piece of itself to become self-reflective (we are not separate from the Universe).

3:10 Sciencephile says «a slight change», but doubles the value of the lambda constant. Please correct me if i am wrong, but this doesnt seem like a small change considering the value was increased by 100%.

I really thought of the same number at first but I changed my mind. 🔥

Perfect Creator makes things prefect!

It's fun to imagine how our "perfect" living conditions might be perceived by alien life-forms that have evolved on a world with completely different biology. 7:21 might be as terrifying and foreign to aliens as living on Neptune is to us...

Certainly feels like it's simple roll of the dice with perfect rolls time after time. It's like being cursed with luck despite all the odds to make it yet still be unlucky to do anything with it. This honestly explains the human experience.

Something perfect, must have been created by something Most Perfect.

How can you say that a Creator or simulation theory pushes the problem back, but fail to recognise or state that the multiverse hypothesis does the same thing? In fact the Multiverse hypothesis is probably the least likely because it disregards Occam's Razor.

6:46 damn bro from where do you get those they are amazing background material

my heart dropped whenever you said the number! 762 was mine you had me in the first half

You help me sleep at night

The question of ‘if a universe isn’t observed does it really exist’ had me thinking, about the philosophical debate over what “matters”. I believe that for something to “matter” it has to be observed by or have an effect on intelligent life(however you define intelligent life). For example, by that logic our own universe had no meaning until intelligent life appeared. The A.I. in all it’s wisdom can let me know if some philosopher already thought of this

5:56 what the dog doin

SUPER 😇

earth wasn't perfectly formed to have life evolve, life evolved to perfectly match the earth.

I can’t remember what principal it was, but whatever makes the most sense is incredibly likely to happen. What sounds more likely to you: God or an incredibly low chance which is so low that our minds simply cannot comprehend? Let me introduce this: if I was to take apart a pen and leave it with a a piece of paper in a vacuum for 10^100 years (assume it’s a perfect vacuum on a perfect earth), would the pen ever return to its conjoined state, write “I’m gay”, draw a perfect drawing of Keanu Reaves, and then take itself apart again? I never did the calculations, but I would say it’s safe to assume that the pen could and would never ever do any of that. If I returned to it 10^100 years, there’s no chance that I would return with my new “I’m gay” Keanu Reaves masterpiece unless it was manipulated by an outside influence.

I’ve now realized that these questions are obsolete, It’s like asking why we have 10 toes and 10 fingers 🧐🤯🤣

I love your videos you explain most things in a way I can understand I'm autistic so sum time's I have a hard time understanding but you explain in a way I can understand so thankyou . Also I think your videos are very funny and educational.

D = 3 is my new favourite constant

2:11 but thats because we are asuming in base of what we know, and in base of this universe evolution... maybe it span other things well never know probably sinse we dont really know the nature of space if its a single one.

Mortals tend to not be very good random number generators, so not every number has an equal chance of being picked. Just something that I felt needed to be pointed out.

i love it when physics and philosophy

Momentarily balanced =! Perfect
