Hope you are enjoying the first second of existence (bit of a tangent this video, but an important part of the puzzle!) Next month let's find out what happened after particles gained mass. Spoiler: nothing not weird.

The simplest answer is that the universe is perfect from our point of view because we were created by it and are governed by its laws, so it couldn't be any other way.

"Planck, had unknowingly, invented quantum mechanics" I hate when that happens, so relatable

I think we can say with great confidence that the creation of consciousness in this universe is the greatest phenomenon ever seen. Out of all the ways this universe fascinates us, the reality that self-awareness was created from some combination of unconscious matter is more mind-blowing than anything else

A small token of my appreciation… one of my favorite channels, fascinating topics and clear, well researched explanations. Thanks! Andrea

The quality of (some) KZfaq videos has far surpassed the old fashined medias like television. It's amazing what level of quality and insight we can stumble upon while surfing YT, and thanks to the algoritm of recommendations, I was fortunate enough to find this utter gem.

The simulation hypothesis has the same problem that the panspermia hypothesis does: it kicks the problem farther down the road without actually answering it. Whoever's running the simulation has to live in a universe that has constants compatible with life, so the question remains of how those conditions arose - just one level higher. I'm not saying the hypothesis is necessarily wrong, but it absolutely doesn't answer the question. Editing to simplify/clarify my position: given that we are in a simulation, two questions that arise are "what conditions allow the simulation to be run?" and "how did those conditions arise?" *These are exactly the same questions the simulation hypothesis purports to answer about our own universe,* and the hypothesis is meaningless if those questions can't be addressed. Another edit: if, as has been suggested several times in this thread, the intelligence running the simulation isn't subject to the same natural laws that we are, does that not inherently contradict the assertation that a "fine-tuned" universe is actually necessary in the first place?

Documentaries on the Universe (heck, even the solar system) make me feel both totally irrelevant and totally unique and priceless at the same time

By logic, a creator that is beyond our understanding of time has to exist to create everything we feel, experience and or see etc.

I am so impressed how you perfectly combined a relaxing, and low, background music with such a fantastic narrative. So many science documentaries that are terrible mixed and are anything but a relaxing lecture. This is not the case. Its amazing how you control the aspects of the narrative, the pauses, the emphasis, the mistery and the logic with a precise description. Your voice sounds from heaven. Thanks for your fanatstic job.

I think it’s cool to think that we (intelligent life) are the universe’s attempt to experience itself. The universe arranged itself in such a way to create beings that could sense and interact with its surroundings and even ponder itself and it’s purpose. We are the very thing that we have toiled for generations to understand.

I’m loving having found this you tube channel. It is wondrous. It fills me even fuller of wonder than I could even imagine.

The matrix idea still requires a creator, plus the laws of physics for the programmer will be different thus it goes to say that a computer may not be necessary to create universes and computers may not even be possible in such a world, thus that is the definition of a God.

The ability to see an event in mathematical terms is something I have always envied. This video has a lot for my old fossilized brain to absorb. I am familiar with some of the concepts but not with all. Thank you.

How are we even here in the first place is the most simple but unimaginable question to answer

I find that the greatest force driving me to continue living and exploring is the curiosity to understand more of this magnificent universe. And, to be honest I wouldn’t want to be immortal only and only if I could know more of this mystery.

Just brilliant as always. Calm clear diction, no distracting music. Incredible info expressed beautifully. ❤❤❤

I enjoyed every second of this wow. These are the things I think about almost daily but never put the research into and you’ve just done it all so perfectly!

“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!' This is such a powerful idea that as the sun rises in the sky and the air heats up and as, gradually, the puddle gets smaller and smaller, frantically hanging on to the notion that everything's going to be alright, because this world was meant to have him in it, was built to have him in it; so the moment he disappears catches him rather by surprise. I think this may be something we need to be on the watch out for.” ― Douglas Adams, The Salmon of Doubt

Extraordinary, excellent. The best documentaries about the Universe I have seen in many, many years. Congratulations.

This channel speaks to me as if we're on the same page. Like we all know about quarks, electrons, blackholes, cbr and quantum entanglement...We've all heard of these theories and equations, now let's talk about them more. I appreciate this type of science on a spiritual level.

It’s amazing how I’ve loosely tossed around this idea in my head for years and then a video like this perfectly sums up what I could not verbalize myself. Thank you all very much

2.5 million years to andromeda. I still remember the Sci fi series 🤟

Perfectly tuned for randomness.

I think, like the Universe we live in, that episode was practically perfect! 😉 Maybe it's because of the length of some of these shows that I was slow to check them out, but MAN I am glad I did! Great channel & content! 👍

Philosopher here. Simulation theory isn't loved by me. It clearly just pushes the question of complexity back into another universe. Why is the simulator's universe so hospitable to life?

Isn't it crazy that we ARE this stuff that boggles our minds? That at some point, every fundamental "thing" your made of was once part of the very beginning of the universe. WE ARE THE UNIVERSE

I just found this site the other day and I'm loving it. Sharing with everyone.

I love your narrative voice. You do a wonderful job

I love to watch your videos. I watch them late at night when all is quiet and I can immerse myself in the visuals and sound. They fire up my imagination spectacularly and I then can then drift to sleep with ease. Thank you for the work you put into these. I much appreciate them!

i almost always fall asleep listening to this, it's just so smooth listening to these videos. I try to stay awake to actually take it in, but it just happens. Great video as always, can't wait for the next one! Also just wanted to say I've recently begun my degree in physics with astrophysics.

This is one of the most thought provoking, well presented scientific videos I've ever watched. 👏

Interesting question, kind of like asking why a puddle of water is the shape that it is - I'd say its because that's how it best fits in the hole it's been given to fill

In my universe the constants of nature produce quite good wine. Thank you, great tuner in the sky.

We are just the universe perceiving itself, and I think that’s beautiful.

Max Planck when discovering the Planck Constant: "So ein Mist!" Everyone here: *indistinguishable screaming and cheering*

Thank you for yet another incredibly high quality release. This channel is my absolute favourite little spot on KZfaq.

You are so underrated. I follow so many science channels but never came across your channel. Well detailed, clean and perfect narration

this is the best channel ever in the history of youtube. thank you so very much!

Great video!!! Thank you so much 😍

This is some fire content, I remember why I love physics so much, reality is some much cooler than fiction could ever do justice

Everything you guys produced and uploaded are absolutely fantastic videos! I already said this but will say it again and again, "History of the Universe deserved multimillion subscribers!"

They most likely reason why the physics is just right for us to exist is because several universes most likely kept colliding and achieving stable states in a recurring manner and once a stable series of computational constants where in place it kept recurring even faster to more stable complex forms that are conscious as well.This would be an evitable equilibrium achieved by any progress in to a more complicated state.

The simulation theory is essentially appealing to the same things as the existence of a fine-tuner deity. It either fails to answer the question by kicking the problem farther down the road (like others have pointed out in other comments), or it is God but by a different name. The only two explanations we have left are fine-tuning by a fine-tuner (God), or that our universe won the existential lottery within a multiverse of infinite universes. Of course, with both of these explanations we arrive at the same exact questions: How and why? How and why does Goes exist? How and why does a multiverse exist? If all we do is propose explanations that require the same questions to be answered, then we will never arrive at the truth. The only way to arrive at an actual ultimate answer is to conclude that whatever the ultimate explanation is, it just... is. If God created the universe, then God had no origin or creator Himself, nor does He exist as a result of some kind of omniversal set of rules. He just... is. If the multiverse exists and we exist in it, then the multiverse has no origin or 'multiverse of multiverses', and all of the rules and mechanisms of the multiverse are built into its own intrinsic nature. The multiverse just... is. Personally, I am a Christian, and I believe in God. I believe that these ponderings are align with the Biblical understanding of God. When it comes to mankind's pursuit of answers, I find that the farther we go with naturalism alone, the more we approach explanations that are essentially the same as God. If we are primarily concerned with the truth, and there is no explanatory or evidential difference between God and a multiverse, why then is the multiverse still preferred? Is it because we have labeled it as being 'natural'? Clearly it isn't though, as the very nature of the multiverse is to contain infinite universes that contain their own natures that are completely different from our own. The only explanation I can think of is that the existence of God has baggage that some do not want. That they do not want to resort to an explanation that their ancestors used, so that our greater knowledge would 'mean' something. That they do not want to be labeled within the scientific community as being 'anti-science', for believing in the supernatural. Perhaps even that they have a grudge against God, or do not wish to accept the consequences of the existence of God. Ultimately, it seems that the only reasons to prefer a multiverse over God boils down to emotion rather than truth.

Great video! You have a great ability to get an idea to someone. I like how you built up the story and everything about it! Thank you

Watching your videos is like preparing for a wedding..Something old, something new, something borrowed and something blue..But always told in such a smooth and entertaining way, you can't help but be mesmerised by it.I love the mention of the Hitchhiker 's guide!

Very Cool! Thank You for Sharing!

All of these are so, so well made. They never fail to fill me with a profound sense of awe. Thanks HotU

My favorite from this channel is the one about why time went forward but every video is a classic in my opinion

"Part 1: Are you special?" Oh yeah, I needed a bit of an existential crisis with my breakfast. I'm joking of course. Great video!

I feel that all of the compounding odds of big bang , the universe , fine tuning ,life on earth and the quantity of it , and finally mankind and conciseness . I believe we are all created

This is an interesting, thought provoking channel with well presented content. I just want to leave some of my thoughts. I think when we talk about why we are here, or how significant we are, or whether the universe is perfect or not, we enter philosophical territory, these are questions that can be looked at in many ways, they are something that can be informed by the current science, but not ultimately decided by it. It is also important to remember that reductionism is not our only option, and that each view has its own problems and merits. I personally think that the most significant things in the universe are some of the smallest, individual people we care about, life, things we enjoy doing, our feelings and the feelings of others, our power to think for ourselves and attempt solve the problems that matter to us, causes we believe in, notions such as love, empathy, fairness, justice, etc. These may also play a part answering the why are we here question for ourselves. I think the Earth is special because it is our only home, and a cradle of life. It does not need to be big or exceptional from a scientific standpoint to be important for us. We do not all need to agree on the same interpretations of observations all of the time, sometimes it is good to agree to disagree from a place of sincere respect. As the video mentions, some people believe in god, others think we are in a simulation. Some have no opinion at all/don't care to. All of these are fine. There are some people of faith in my life that are so kind and good in their actions, that it makes me think if I were to believe, it would be because of their example. Anyway thanks for reading, hope today's a good day for you.

I am glad i subscribed to this channel and 'History of the Earth'. Your content is absolutely amazing and worth binging. Yesterday I re-watched some of your videos and was actually wondering when a new one would drop and here it is. Please keep up the good work and do upload new content in the Earth channel pertaining to the geological evolution.

Quite simply put, energy cannot be destroyed it only change forms and it's always balancing itself.

Simply Brilliant!!!!

Another masterpiece - thanks a million.

Can't wait for new docs, I rewatch the old ones more than twice they're that good and informative plus the imaging is fantastic

Since I was 10 y.o. (1958) , I would tell people to stop complaining, do you know how lucky you are to be alive and on a planet such as earth. What a gift. This is how I've lived my life!

Everything in the world is perfect. Look at around, the flowers, your floor tiles, your body, and everything around is just RIGHT for it to just be. So why is it so hard to believe that what created us has to be different and can’t be perfect to hold us together. If it weren’t perfect, then we would burn or maybe freeze. So the real question should be, why do so many people fandom to believe that the world is just perfect??

we give meaning, that's why we think it's perfect. but it's neither perfect or imperfect. it is just is.

I've found a new fundamental constant called HoU Constant which is: 1 = 3 This is how many times I have to watch every new episode until I'm satisfied. It's just so good!

I think these are fuggin awesome! Thank you so much

it would be akin to having an object permanence of other universes (4th dimensional physics, quantum), like how our pets have trouble with object permanence of the 3rd dimension. it can be said that we exist in a quantum dream (at least), meanwhile they exist in a classical dream (or something around that).

Breathtaking video. Absolutely wonderful. Thank you for the upload.

only in a perfect universe, can a bubblebutt exist.

Watching this was unexpectedly very emotional to me

Thanks!

"if you study science long enough and hard enough it will force you to believe in God" Lord Kelvin....

This is a beautiful way of putting forth one of the many ways our universe is utterly perplexing!

If the Universe was perfect, I wouldn't have crippling depression and borderline alcoholism.

I still feel there is a part of us that can not be defined or explained with mathematics, and that’s why we have the word miracle

What a joy to watch. As always topnotch quality. Instant click and like. Thanks a lot for posting.

There's so much i don't understand about the universe and yet i'm facinated by it.

I find it pretty amazing how life took hold and evolved on our tiny planet. I hope that people will evolve from the belief systems that separate us and see the amazement of life.

Before you ask: "What are the chances of a perfect universe?" It is more reasonable to ask: what is the probability of the existence of a universe without a creator, and the obvious answer is zero

subbed, really like the mystery of the UNIVERSE

Here's a thought. No matter how deep we look into things, we only come up with more questions. If we were made by a god, where did they come from, what dictates their existence. If we are in a simulation, what made the universe above ours possible. If we are in a multiverse, what rules dictate said multiverse, and why are the universes so similar.

"Our physical existence in this universe is nothing more than the manifestation of a huge number of interactions of its fundamental pieces, and all these interactions are dictated by the values of the constants of nature". This is really, an amazing and mindblowing way of seeing absolutely everything, all this video is *fascinating ♥*

Thank you for your work

I really enjoy subjects on physics and mathematics, they are important tools to approximating our universe. The question on why we're so special certainly is a pondering one, but I wish the subject of purpose was implemented. Atheism rose from the French Revolution in 1789, as the religious leaders have not treated their people the way they should have. If you recall what they've been doing, it is grossly not reflecting the Bible, and because of their forceful intentions, the people revolted agianst them. New thinkers rose, proposing new theories in contrast to religious texts. To be honest, they've made firm theories that stand not on full reasoning, but refusal to Faith. And everyone that followed did the same. It is like someone who attemps to get into a walled garden by climbing it's vines instead of using the door. Don't become captive to the lofty philosophies of this world. The big conclusion to everything is not at a distant finish line, but is right in front of you all this time.

This probably has nothing to do with this video but I “constantly” see the number 137 through out my day. It’s brought a lot of Curiosity to what this means and if it’s some kind of message. The fine structure constant.

An Anthropic principle of some kind is a valid argument. If we assume that the universe at an atomic level has no fixed form and is just potential energy, probability and time, with no solid reality, it's possible we could be "seeing" back in time through our instruments and eyes a version of a universe that should exist if we were to exist. We are manifesting our past universe out of an infinite possible number of potential universes. A Feedback loop of mutual creation with no beginning in time other than local time. This is a real hypothesis.

Good lord these videos always bring out the crazies

You are a perfect teacher for quick, conceptual thinkers

Being alive on this earth is like finding yourself confined to, yet nonetheless free to roam within the pages of a famous book, somewhere on a shelf, in the library of babel. Thousands of books nearby in the same shelf may be full of gibberish, but who knows what masterpieces may lie 1000s of bookshelves away. In other words, Who are we to define order through the lense of a universe intent on creating chaos?

Literally (literally literally), the perfect verb tense is called perfect because it has happened. It has happened and is thus perfected. My Latin teacher taught me that.

This is a beautiful informative presentation, collating the scientific understanding of us in the universe. In attempting to address questions of this magnitude, I'm struck by how more questions are apparent. But I'm still trying to understand the primary catalyst for it all, the Big Bang. After all, science has no real idea with any certainties what was before, what was there to cause it, or was there nothing before? Further, although everything has come from a point in the Universe and is still accelerating away from it, you cannot point to where that is. If those questions cannot be answered, then the whole scientific endeavour surely is in question?

Shows like this just reinforced my absolute belief in a Creator the details the laws of science Ps 19 the the heavens declare the glory of the Lord

I wish you'd have also covered the explanation that the constants appear fine tuned because as the simulations have shown, most other combinations don't allow for complexity, and thus wouldn't allow us to exist to question the specific values of the constants in the first place. IMO it's the most compelling explanation. This covers why the constants have their specific values, leaving only the 'how' (which is covered by regular physics stuff).

Loved the topic. You should follow up with a video of the problems with navigating through space if we ever were able to come up with tech. To actually travel it.

I just love thinking about these kinds of questions.

Another mind blowing documentary. Wow. Thank you for taking the time to create these incredible educational videos and for making them so very interesting and engaging. I wish learning in school was this fun. It seems that the more science matures the more scientist have to go back and re-examine their core ideas. That scientific maturity leads to greater understanding of the complexity of everything here on earth (and in the universe), creates more questions then answers and to understanding there exists more order then once thought. I vote for God. As hard as the belief in Him is, it is harder, for me, to believe all of this Galactic Order, not to mention organic life on Earth, happened by some perfect accident. Time will tell the truth.

A perfect universe yet we can't survive 99.99% of it

I am very thankful For created this incredible universe and is allowing us to experience life to its fullest. Man is that he may have joy.

33:50 I would argue that the value arising in the sub-universe will not be entirely random, but actually be a value that describes the value of the containing universe. More than likely, it would be a subset of values either bounded by the infinitesimal value above and below the relevant accuracy of the universe (so 12.01 may be12.011 or 12.009,). I would expect this one because a wavefunction would average to it, allowing a connection to be made to the uncertainty principle. another possibility is that the values of the sub-universe integrate to the value in the containing universe, which would preserve continuity in the containing universe

Wow! This Channel is awesome. Thanks for sharing such a Quality content. It's interesting how knowing more and more about our universe rises more and more questions. Such a complexity of circumstances to fit together "by chance" just to aloud us to experience life ... and death. The biggest question is WHY. I'm not really sure if science could ever give an answer to this question because probably the answer is beyond matter. It must be a point in space and time where science of matter meets "science" beyond matter. Who knows...

Wow. This channel deserves way more subscribers. Sublime content :)

The voice is mesmerizing... The information is compact n fulfilling

Praise the LORD! The Universe is fine tuned for life because of the LORD. "The heavens declare the glory of God; and the firmament sheweth his handywork. Day unto day uttereth speech, and night unto night sheweth knowledge. There is no speech nor language, where their voice is not heard." - Psalm 19:1-3 "For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who hold the truth in unrighteousness; Because that which may be known of God is manifest in them; for God hath shewed it unto them. For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse: Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Professing themselves to be wise, they became fools, And changed the glory of the incorruptible God into an image made like to corruptible man, and to birds, and fourfooted beasts, and creeping things." - Romans 1:18-23

Beautifully written, great graphics and most of all thought behind it all...
