If the probabilities are this low, it’s much more likely that it’s indicating that we simply don’t understand something.

The odds that our universe is the way it is, is 100%.

I need to stop watching your videos when I try to sleep, I keep getting stuck with all the thinking and rewatching and suddenly it 5am and my brain just won't shut up... But seriously, thank you for making videos that actually makes me want to learn more. ❤

I love how existential philosophical questions overlap with astrophysics in so many of your videos. They awaken wonder, which is at the roots of wisdom, in my opinion.

The multiverse hypothesis is still a bit of a conceptual cop out. Is intuitive from a physics perspective, but like God, is not really testable.

Watching these videos stoned is the greatest thing ever.

If you ask why the universe exists, and the answer is multiverse, well then the next question is why does the multiverse exist, and how did it come to exist. This leaves me feeling unsatisfied with the multiverse explanation, it still doesn’t really give me any more answers, it just introduces another layer of abstraction.

Observer effect and anthropic principle. We see the universe in its peculiar uniqueness, and change it because we see it. And it is suited for us, uniquely, because, if it were not, then we would not exist. Thus, we must see a universe that suits us, and we must see it and be seen by it.

When I was a kid in the '50s I read in a comic book what turns out to be the perfect answer to our existence..."In an infinity of time and space all things that can happen will happen".

As far as I know there is no accepted model for dark energy. Given that, I can't understand how the probability distribution of the density of dark matter could possibly be predicted by any theory. Maybe you can make a video about that! I really enjoy your videos, thanks for making them.

absolutely love your videos and your sleep podcast. you are only furthering my curiosity in the universe and filling me with such awe. thank you :)

Beautiful video with incredible ideas of a possible multiverse, thanks Astrum! We living beings are also a (albeit very small) reflection or expression of our universe. Everything here and there is connected and everything works with natural (material and spiritual) processes, from quantum mechanics to chemistry, order and chaos, cosmic expansion to retraction, karma and all other tools of life! However, you first have to learn to live happily, sometimes it's not that easy...

The description of the spacial multiverse theory felt a little inadequate. The currently preferred version is the eternal inflation model, where cosmic inflation didn't actually stop, but bubble universes periodically "pinch off" while the rest of the bulk continues to rapidly expand, pinching off more bubble universes as it goes. These "island universes" are fundamentally separate from each other and under no obligation to have the same laws of physics and constants. I also doubt that universes resulting from the many worlds interpretation, would have different constants and laws of physics, since they are the result of a branching of a parent universe with the constants we experience. If an unstable nucleus is in a superposition of decay or not and then we experience the weak force triggering a decay event, then presumably another universe branched off where it didn't decay, but that universe would still have the same strength of weak force and the same mass for the proton and W boson. It stands to reason then that other constants such as the gravitational constant, fine structure constant, C etc, would also remain the same.

I just wanna say thank you Alex. You're one of the only space-youtubers out there that doesn't actively make fun of those who have beliefs that differ yet still love to learn about the universe. Keep up the good work ❤

I swear I was driving in silence the other day thinking about this exact thing. About how our Universe won the Multiverse Lottery, but who printed the ticket? Who rolled the numbered balls around in that metal cage? More questions, more answers; more questions.

One of the things that's annoying about trying to couch this in terms of probability is that doing so assumes any or every other value was actually possible. It's garbage math.

The chance of life being possible in the universe is known: It is 1. We are 100% certain that life exists in the universe. If a model suggests that there should not be any, then clearly that model is wrong. Make a better model. Introducing multiverses or gods is entirely unnecessary. By the way, the chance that the universe is the way it is, is also 1. And although life exists in it, most of the universe is an extremely hostile place.

Ill be cleaning my room to this now, and will sleep to it tonight, Thank you!

Amazing as always!!!

Great video series. And like some are finding, the deeper you go the fewer answers appear & the questions grow exponentially 😂.

There is another much more useful theory that the underlying values of the universe are dependent on each other. Changing one value has a knock on effect that changes other values that eventually returns the values back to what we see. Asking what would it be like if gravity was stronger isn't a valid question because there is only one possible value dictated by the dimensions and symmetries in our spacetime.

Under a minute... I think the first question is "Can universes exist in any other way than ours?" There is likely to be an underlying mechanism that creates all the universes. Something about this mechanism may preferentially select key starting values. Everything we know of behaves this way, so it seems reasonable to expect the same here. It sounds like 1e56 is the entire possibility space - I have no reason to think each of those possibilities is equally likely - I have many reasons to believe some range of states disallow other ranges of states. I hope you don't skip over this.

The most philosophical video I have listened to with regard to our existence..... beautiful!!

This misunderstanding of odds is very annoying to see people constantly babble on about. Take your birthday: What are the odds that you were born on that day, on that moment, in that room, in that country, on that continent, on that planet, in that star system, in that galaxy, in that local cluster? Like eleventy-trillion to one!!!!! I read about the different types of the Anthropic Principle years ago and I latched onto the Weak Anthropic Principle. The fact that we’re here to live and think about these questions is the only reason it seems impossible: but alas, we’re here! Therefore, it’s possible. Odds don’t matter here.

It's hard for me to put into words how much I appreciate your channel. I think it has become fashionable to scoff and dismiss many natural conclusions from the science we know. Other ideas and conclusions which imply we aren't important and our lives are meaningless are accepted at face value even though they are based on blind assumptions. People will laugh and mock someone for saying there's a chance we're the only world with life on it because there are a trillion planets in our galaxy, but we still only have a single data point. Maybe the odds of a planet getting life are 1 in a septillion. Everyone dismisses the possibility of a constructed universe, but there are insanely specific constants all over the place. In my opinion, this mode of thinking comes from a good place. A few hundred years ago many people were blinded by stories from organized religion. The pendulum swung away from that and now we have people blindly defending conclusions without evidence just because they imply we aren't important and that seems intuitively correct. What we need is more people taking your approach. Don't stop looking for scientific truth. Don't ignore scientific evidence. But don't conclude things based on assumptions and always be honest about what we actually know and what is an assumption. Otherwise you become the person who believes in a multiverse because it seems more scientific than a god when the reality is neither explanation is scientific right now and either or neither might be right

This makes me want to write a short-story about someone pings across the multiverse, experiencing what they would have been in a universe different from ours witje different rules...

Your narration has fixed my insomnia. Thank you!

where does the 10^56 comes from? I missed that part

The religion of science, the science of religion.

As always, a great video with clear explanations, really meaningful images and scientific integrity. Thank you, Alex. Either physicists and astrophysicists have to really make some major breakthroughs or I have to live for a VERY long time! I really want the evidence to support the assumptions needed and the models of the different kinds of explanations for our universe. At my level of understanding and knowledge, it just seems that the multiverse idea is the most appealing. Going to the level of the origin of matter at the Big Bang - it might be that different foci of quantum particles acquiring mass through interaction with the Higgs field emerge, with each focal point being slightly different, perhaps in dark energy density.

I am not a fan of multiverse ideas in general, but the way you tackled it, I love. You are candid and honest, as well as thorough. Thank you for what you do.

I'd much rather it be random chance than believe there is 'something out there' that wants me to be able to see how mind-numbingly tiny it can make me.

Thanks for all the good job!

"Just so you know Jeff, you're now creating six different timelines."

All it hints at is that given sufficient space/time anything that can be, will be. Given that both time & space may be emergent rather than fundamental it suggests we are not yet sufficiently informed to make claims for other options.

Another video of our worst physics claiming to be our best physics.

i think if you go far back in the past, anything that ever happens is basically a miracle, because the chance of going from a point in the past to the exact present we inhabit is basically zero. but, on the other hand, from the perspective of the present, what exists is basically inevitable. it's all a matter of perspective.

This guy "Astrum", is a great, great video creator and editor. 💯

If you have somthing you created and loved you would not push to get it to understand how great you are at creating you just silently appreciate it for what it already is and dose ,this is unconditional ,this is an awareness that could create entire galaxies.🙏🌠

My main gripe with the concept of intelligent design is that it implies whatever designed us or our universe perhaps has their own laws of physics that work perfectly. So, although it may explain why _our_ universe behaves the way it does, it doesn't explain our creator's universe.

Thanks, Alex! 🌌

There is one absolute certainty: I AM going to crank 1 out to some smut immediately following this video. However, going to bed and sleep following this event are an uncertainty. The prevalence of dark energy in this region of the universe presents several probabalities. High-energy, low-frequency sounds, accompanied with lyrics that rhyme, are just one good example of what could occur. Pulses of red and blue lights after high-energy outbursts are more common as well. Thank you for reading. If you like this, be sure to check out my other comments. All the best, I'll semen til next time.

10:34 I have had this idea in the past, I though of what if the multiverse was just the same universe so far away that they can interact with each other without travelling in a way that’s like multiverse travel, cool that I though of this idea separate from who ever came up with it.

if the universe has an eternity to happen, it will eventually happen!

2 things: 1) Invoking anything higher level than the universe begs the need to explain that thing; you can't escape the anthropic factor. 2) Philosophically, what's the motivation for invoking a causal relationship between "bubble universes", even via a parent "universe" or substrate? This appears to be a limit of our imaginations. In other words, we simply don't need to exist within a continuum that supports any other "universes". We were inevitable (evidently), possibly without any pre-conditions. Chance of anything => inevitability of everything.

Dark Energy; the magical inflating invisible pink unicorn of science.

I really want to watch the first video in the series that you mention, but I can't figure out which video it is 😕

We can experience the joys of life.. ‘ shows a traffic congested parking lot ‘ … you got that one right on the nose, Alex 😂

If its that far off, and people cant figure out why, because other things are spot on. then the simple answer is the people are wrong, their maths is wrong, or the wrong maths is being used, or there are still plenty of things we don't know exist or understand about the universe, that we just cannot get to the correct answer because those variables cant be taken into consideration. Its also probably about time we stopped worrying about things that arent going to effect us as a species for another millennia and start focusing all science onto things that will have a positive impact on humanity as a whole in the next century. Understanding how we came to be is irrelevant if we continue to drive head long into the wall of oblivion we seem to be going towards.

I feel a bit sad when i see science channels with millions of viewers discuss fantasies like this instead of asking the real questions that should be asked in physics

Another mind bending classic. Thank you, Alex!

So much eye catching imagery. How many of these images are actually from Hubble?

I disagree, if you think of multi verse concept in linear time line, the theory still stands, as you would have infinite attempts to roll the dice until the right critiras are met to produce galaxies and life. You would have no means of methods to prove what existed before and or after since we wouldn't exists at those time frames. So how a linear model is different than a pararrel multi verse model different? This is definitely a topic that is for the future, not with today's knowledge or tech to be able to explain.

This is getting ridiculous. Not only do humans think we’re the only life that exists in the whole universe, now we think we’re the only life that exists in 10^56 universes? I’m sorry I just don’t think we’re that special.

I think one type of multiverse has been overlooked in this video: the bubble/baby universes created by the inflation after/during the Big Bang (inflationary multiverse). All of these universes are part of a larger entity, rather like a Swiss cheese in style.

"We're here because we're here!"

So weird how, in spite of the overwhelming evidence of design in the physical world, 'scientists' stubbornly ignore the existence of a Designer, just because they can't prove it, although there are a myriad of other things they can't prove.

And, yet, my life is absolute garbage, always has been, & I want to die. "Lucky"? No, "cursed" is more like it. EDIT: I imagine it's difficult for haves to grasp how bad life can be for have-nots that they wish they had never been born. I get it, too bad you don't. But of course it's unsurpirsing, given that there's no consequences to you for not understanding.

Multiverse is the longing for fairness in the midst of chaos

Here is some poetic license: The word "multiverse" could describe a song or poem with paragraphs - multiple verses. Then apply this thought to the universe, and there could be other universes with their own constants - their own vibration frequency. And this comes back around to the three leading theories of the multiverse. It's at the level of philosophy, but it's a fun thought experiment.

One minute in and Genesis 1:1 is already proven.

I hate this type of ridicule. “The universe should not exist!” Have you tested every type of universe? Then stop telling me that ours is rare.

You should feature the mysteries in sci.

The holographic principle also accounts for this deviation. While an infinite amount of projections happen simultaneously, they all manifest from the same source, the surface from which all information is stored. This is the same way information is thought to be conserved within a black hole. Rather than the information being proportional to its volume, it’s proportional to its surface area.

Ai thumbnail... Shame on you guys

One of the universe questions we probably wont know the answer, if we cant even see whats beyond the observable universe... We cant neither know where it ends, and if we dont know that less will be know whats outside of it.

The quantum multiverse is the most appealing but I like to think of it only as a multiverse of endless possibilities until it happens then it's set into a single timeline/universe

I have an idea, there are many multiverse and each has many universes that all share a universal constant, each multiverse has a different constant for its universes.

I've assumed that both multiverses exist: There are infinite universes in different dimensions (space, so to speak), and in time. Ours is one of an infinite number of pulsating universe phases in an infinite array of universes. Not only is it inevitable that we would exist, but it's also inevitable that infinite exact copies or ourselves exist, and will continue to exist forever.

I personally am betting on the multiverses separated by time. It's likely a cycle of big bangs, probably. Idk. I just like that idea the best

The “space differentiated” universe could explain the absence of antimatter in the observable universe. It could be that there are parts of the nonobservable universe that contain only antimatter. Think of the nonhomogeneous distribution of matter in the observable universe and expand that. In places matter dominated enough to have leftover matter after all available antimatter had been annihilated, and in other places antimatter dominated. Also, how do these concepts align with the holographic universe theory?

if a puddle wakes up in a pothole on the road, will it look at that hole and thing "wow, what a coincidence that this is shaped perfectly to fit me" or will it consider that it came to be that shape because the hole was that shape first?

I'm sorry, but I confess that I laughed when the phrase "all the joys of life" was accompanied by video of a parking lot.

Voltaire said, "We live in the best of all possible universes." It's a theory thiat is hard to prove like string theory.

You should count the number of times you use "if" or "possibly" or "perhaps" as part of the foundation of the Multiverse theory.

The relativistic cosmic horizon multiverse is absolutely real (relatively speaking).

I’ve spent many years in the field of telecom. Thinking about dark matter as, not matter, but as gravitational interference from neighbouring quantum universes is a lot like a telephone wire. The more signals going through each pair of a 100 pair copper wire for instance will cause cross talk and interference, slowing down the rate of information. Interesting to think about

The universe wasn’t made for us, we were made for the universe, we adapted to it.

Stacked against infinity is 10 power 56 insignificant or god like a great number ?

Some people can communicate with the dead. Edgar Cayce a clairvoyant stated that there is a thin veil between people in the earth plane and those who have passed and are in the spiritual plane. There is another universe.

You missed eternal inflation potentially constantly creating new universes in the same process that created ours.

Then who made the multiverse? “Give us one free miracle, and we’ll explain the rest” -Terence Mckenna

I think its probably an emergent phenomenon. The value is where it is, because that is how it evolved - because it could only evolve that way. How it "evolved"? Idk, and i think were a ways off from understanding. But were speculating on spooky origins of a spooky substance

I think it's probable there's some other dice rolls besides our own.

Your videos are a blessing, please never ever stop

Great video as always but why would you change the beautiful thumbnail? 😢 Edit: Ok now i love the current thumbnail. ❤❤

so yes, there are two options, either all kinds of value exist in a similar type of situation elsewhere, or there is some reason why it is always very low, i personally find this to be unlikely, because all we have to do is go back to inflation to find a universe so skewed that normal matter was not a thing, no atoms could form and so on, i think it is more likely that all vacuums even if they have variations in laws and lifetimes, still have transitions, slow periods and fast periods of expansions, and eventually all pass away through further phase transitions. i am very skeptical about crunches, because models like that takes away a reductionist framework for understanding expansion at a deeper level that requires expansion to be more or less permanently directional, from phase transition to phase transition, such that all of space is always expanding as some rate with respect to the matter inside it, and that is related to an increasing entropy of the vacuum configurations and the fields in it and so on. instead of a crunch you would have space expanding until it has lost too much energy and the interactions and matter like atoms, electrons and the associated fields, themselves decay, as the small scale sub plankcian physics that make them up undergo a phase transition, and essentially starts in its own hot dense state as it is no longer fed by the decay of the phenomena at our scale of interaction and object. it is not really this simple, but more or less it could work like this, then it would form smaller scale particles in much greater number and the whole thing starts all over again, even though the universe already expanded for a lifetime before, the small scale detail that we cannot even measure now has a life of its own and starts in a new hot dense state. something like that is possible without any part of the system ever contracting.

Fundamental randomness doesn't produce eventual outcomes. Order and Causality are something else.

People have some funny ideas about what life was like 30 years ago, so I'm not surprised if they are wrong about the universe's origin

I believe that every blade of grass is exactly where it should be, exactly by quantum calculation

It make me remember the old google

I bet Hanuš could tell us the answer

Bro would the theory of black holes count as a multiverse

If a cyclic multiverse, or any other kind of multiverse; how did it *START?* And then we're right back right where we started...: a Creator... The adage still remain: "Give us one miracle, and we'll explain everything else."

wow, great video!

8:14 It would also work to fo this serially instead of in parallel. The chance of getting a 6 if you throw 6 x 6 sided dies or throwing a die 6 times in a row (assuming that the previous results doesn't affect the next one, and you don't know the results of anybof those throws before you look at all of them) should be the same, no? 9:39 Guess that fits my suggestion pretty well...

"...we have no proof that it doesn't exist that way." Just like Russel's Teapot.

That perspective does make sense, that planeta, stars, and living beings shouldn’t really exist… it’s all down to fractions of fractions of luck. But also, despite life being this grand “miracle” and we should all be grateful to be experiencing it, we know it is not perfect. Animals, at least that we know of, operate on survival mode at all times. They know what it’s like to not be hunted, to be hunted, to be hungry, to be satiated, to be “horny” and other “natural” processes shared by all living things. They don’t sit and reflect “ah, today was a good day, I’m so grateful to the universe.” That’s a human, higher intelligence concept. But life is still just as much of a delicate tightrope walk for us… at any moment, we could be hit by a car, caught in a freak explosion, or a crime. Or catch a disease and die… merely to be “alive” is just as perilous as if one were born as a celestial body, a cloud, a rock, a piece of magma, a water molecule, or even an atom. We are no different than “natural” materials and objects. Living beings are made of the same elements as the universe, after all, and scientists say “we are all made of stardust”, and that’s true. What’s different is that we can reason and experience emotional responses to our situations. In some ways, that’s worse than if you were a deer, or a bird, or a wolf, or any other animal that is simply operating on the instincts of hunger, reproduction, sleep, and fight or flight. Humans are aware of what’s going on so much that we try to suppress our natural instincts. Hungry, diet. Horny, control yourself. Lol. If someone threatens you, turn the other cheek. Tired? Caffeine.

I’ve always liked to believe in a multiverse. It answers the question of existence. Why are we here? Because if everything is possible then of course we exist.

Your voice sounds exactly like the Columbia researcher dude from the Cool Worlds channel.
