Fine tuning is God's last hideout.

The universe wasn't designed for us, we were designed for the universe and if it wasn't we would not be around to observe it. This video is scummy for not mentioning it.

The universe tends to take the easiest route; that, for example, is why we are made out of Carbon.

5:25 so you’re saying we can get Silicon life! 😆

If the multiverse is real, that means there's an edge to our universe! We need to follow the edgy alien teens!

that master dial is called God

A curious thought for those interested, what if the multiverse is actually a machine learning simulation that is running millions of instances and we are the NPC's :o

If that is the case, we need to redefine what the word “real” means. To me, whether you are in the actual reality or a simulated one, that doesn’t mean you are any “less real”. You still feel real, you can think, experience, feel, taste, etc. They would both be equally real in my eyes.

It’s called the simulation hypothesis

I've never understood the idea that the fundamental constants are somehow variable. That's what they are, why would they be different?

Just curious, but how do we know that it is physically possible any of the constants could be otherwise than they are? I mean, sure we know it is _logically_ and _epistemically_ possible, but without other universes with other values for some or all of these constants to study, how do we know there isn't a fourth option to explain the apparent fine tuning--that these values are physically fundamental, as in no other universe could form but what did? So while other hypothetical values for these constants would be logically and epistemically possible, they wouldn't be physically possible under this hypothesis. Why isn't this hypothesis an option?

This is what has been bugging me too. I would refrain from calling it “fine-tuning” because that would imply an intent to have us here. For all we know, other universes my have vastly different laws of physics that give rise to a completely different kind of life and they would be asking themselves the exact same question; they would also think that they are “fine-tuned”.

Just a gainsaying layman here, but perhaps the "fine tuning" of the forces that engender our particular chemistry would simply produce another chemistry if altered. It stands to my reasoning that in an infinite universe many chemistries are possible. At the end of the day, what do I know?

we can never there is God or no God, I choose to believe in GOD , i am a sanatani ( Hindu) it gives peace

You are allowed to believe whatever you want, but I’m not going to call you rational for it. Believing because it makes you feel good or it “gives you peace” is not a valid or rational reason to believe that a god exists.

Ah God, the intentional knob fiddler

How can self replicating machines and and other future techs seem so easy, yet the vastly more likely species to observe from they are part of is not ours? Not all graphs have to go to infinity, so perhaps the graph of number of obervers over every constant put together never goes higher than roughly our population.

The pathetic attempt to save string "theory" will create gaps to be explored by religion. String "theory" is not Science.

No. But the multiverse theory is attractive.

I can PROVE many of us have already consciously shifted to parallel universe, swapped bodies with another physical version of ourselves. Anyone who don't believe me, find the oldest VHS video of E.T. and listen to that famous E.T. line 😆 also that Freddie Mercury some we are the champions, if you remember the last 3 words being OF THE WORLD, well good luck trying to rationalise it 😆😆😆

Animeme's Courage Wolf says it very succinctly and I don't believe it could EVER be unnecessary. Here's the quote: "You are the product of 4 and a half billion years of evolutionary success, F×>^#NG ACT like it!" (Edited for content & tactfullness!)

Some think certain drugs allow you to come in contact with really existing "other levels with different life". I wonder if any genius astrophysicist has ever tried it and perhaps "they" knew some answers but it's like our brains are not capable of thinking enough out of the box. For the moment the most likely to me seems modal realism.

His 3 possibilities overlooks a 4th: If the universe had different properties, it might have been possible for some sort of consciousness to emerge. Life as we know it exists in this universe because this universe supports life as we know it, but that doesn't mean life as we know it was the only possible "life" that could have sufficient awareness to ponder these questions. In fact, there might be other sorts of "life" elsewhere in this universe, too far away for us to ever encounter, which is nothing like us other than sharing our abilities of perception and thought.

They are shown signs after signs and yet they deny! All things have been created in balance and order! All things have been created in pairs!

If humanity is alone in the universe its not depressing. Its a relief. It means there is nothing to challange us, no other life to ever threaten us. It means we are singular and superior. It is the best case scenario.

So many unusual propositions, among these creator does not sound so unusual. Either be behind the simulation, some form of intelligent consciousness on another level, but science just wants to get rid of god. Buhuhu creator.

This video doesn't do due diligence, you need to say what is theoretical and hypothetical more, more sources and prior explanatory videos please. Love it otherwise.

Or life would form totally different in ways that we can't imagine

this reminds me of a question i have. why dont we experience space expanding? why is my arm not exploding into a billion atoms?

well the real implication there are more universes is the fact there are dials in the first place. it gives you the opportunity to say that things could be different. but all we really know is that things are like the way they are now here. we dont even know if our own universe really exists yet and somehow we think there are more? you know what really doesnt make sense to me is how is there even a universe at all? i mean seriously not only do we as humans get to experience life in a comfortable part of time on a great planet but there is ALLL of this other stuff like planets stars galaxies supernovas black holes outside of our own galaxy. and there are super clusters of galaxies that are so huge you cant even begin to truly fathom it. and the universe is webbed with all these super clusters in a gigantic habitat bubble and not only is there all of that but even potentially different other universes. its just really crazy.

What if there's no multi verse, but the same universe going through a cycle of compression and expansion, changing its physics every time?

Multiverse is the new god now

Isn’t the chance 50/50? It either did or it didn’t. 😏

No! Life just needs a solar system and a planet similar to Earth to support life in the universe.

Your mum does 8O

Our universe is not finetuned to support what we see. What we see is finetuned to our universe. The way we look at the universe is wrong in my opinion. The universe does not think in math, the universe did not want to create life somewhere on a remote planet. the universe does not 'think' like us. Our math and science is are the languages we created for ourselves to explain what we see in the world, and for now those languages seem to work quite well for us, but the universe did not come up with these, we did. The universe is the ruleset that allows things to happen, energy balance and conversion is the key here, and that is the ruleset we, and everything in it, have to obey, because, in my opinion, that came out to be the only possible way it could. To think the universe and it's values are finetuned for us or existence at all, is arrogant. Again, this is entirely my opinion.

Either I'm dumb af or this video is not meant to be understood by the average human with all the scientific stuff he is throwing out. Lmao

Thanks out unkverse futre. Has flt ftl universe bump sub light unverse that circle fitree 21 centry earth

Some recent studies show that our universe might not be isotropic

Just submit that there is a creator for all this tuning. I can't imagine why the idea it self isn't on the table. You believe there is an 10^500 universes and they are different and not related to each other BUT can't think that GOD create all this amazing mind boggling universe!!!

An infinite number of universes... Shakespeare... something like that.

What if there were different types of life let me ask a different question what if the building block of life in our universe are a standard in this universe now one more question what if the elements we know are just a fraction of all possible elements of all universes so what I'm asking is what if the fundamental building blocks that make life as we know it are different in other universes

I know this is not a recent enough episode for me to ask this question, but I have nothing better to do in lockdown....but, if we see particles annihilating each other, or seemingly popping in and out of existence, then couldn't it be possible that these particles, by popping in and out of existence, could do the same for other universes with the same parameters for the forces and values of the fundamental particles? Does this make sense? For instance, if a quantum particle disappears and then reappears, do we know where it went? If there is an even amount of matter constantly popping in and out of existence across all these universes, then entropy is not broken (in fact it keeps increasing), and conservation of mass and energy is also, not broken.

Where does the multiverse stem from....and also where are the boundaries that encompass the multiverse

Obviously, i couldn't say "damn, i would ba dead if i came out 5 minutes earlier" if i came out 5 minutes earlier, could i now?

isn't it possible that one constant derives the other, which would explain the correlation between each constant? Therefore, many workable configurations exists and life may be possible in another form beyond our comprehension?

You forgot option 4: It's impossible for those dials to be anything else, meaning they aren't variables and there are no dials.

that is option 1.

Life is a label created by ignorant people intent on their self-importance and insecure in their existence, which is less than a blink of an eye.

Why should we believe that "other universes" can exist, or even must exist? That's an assumption that is not experimentally nor empirically verifiable. Mathematical assumptions do not allow such ontological assumptions. It may as well just be confirmation bias from vestigial presuppositions in a culture of dogmatic traditions about ontology. It may very well just be "math-fantasy". Indeed, maybe we live in a fine-tuned universe because that's the only possible way for a universe to be. I.e., we could simply be in the _only_ *possible* universe. It's just as possible that there could "be" an infinite amount of different but impossible universe-arrangements, but they could not exist, by virtue of being impossible.

Hey bro @PBS Space Time--So in the case that we were lucky to have come to this goldy lock universe--We start to wonder the origin of everything. I want to see if you can answer this, but where dis the origin of life come from and what reservoir contains this life. What there some kind or space mold perhaps or maybe just we came from some fermented space substance.

Love your channel btw! However, just because the universe contains life does not mean it's responsible for having created it. If I craft a pot and fill it with water, the pot did not create that water. What say you? (Still waiting for science to prove life can be created from unlife).

A chem free universe sounds nice, we can make do with maths and physics 👍

Are you french?

When faced with the inevitable truth of "perceived reality" most prefer to stay blind. I can't say I blame them. Weather we find alien life forms or not is sort of irrelevant within the grand scheme of things (as they would be also be captive to the holographic state of our universe) 🤔 ..... It would make sense that every sentient being has volunteered to exist within this holographic state and has a contribution to the ongoing existence of our "Universe"

🤔👍🏻

REQUIREMENT: no pre-existing aliens that develop AI

Maybe math is man made and more of a language that humankind uses to interact with the universe around us. These constants might not have any independent existence.

The Universe is no more ''finely tuned'' than a hole in the ground is _tailored_ to the puddle within it.

No.

Him- "Here's one totally uncontroversial statement " Me- "F U SCIENCE MAN! I BELIEVE WHAT I WANNA!"

Life is no accident!!!

E8

does someone have a list of these constants at 1:44? is this the cosmological constants? I would just like to understand this a little more, or is this graphic just oversimplified? I just don't get what these dials mean lol.

The universe isn't "finely tuned" for life. Life is "finely tuned" to it's environment.

So then, it could be that at one point other universes could have supported life, and that there are some yet to support life, amongst the remaining "dead weight" universes. But thanks to that particle horizon, we may never know by conventional means.

Does anyone know the music composer? Wow, that's all I have to say!

Allah made the values perfect

Perhaps before our universe was here there were a number of others, some finite number. Some would be created and not be able to hold themselves long enough and so simply collapsed. Given enough time, it seems reasonable to suggest that there would eventually be a universe that holds it's self in such a way as to be able to create the universe we see today. It's a little like nature evolving by trial and error but in this case, the universe. If this were the case then there wouldn't be a need to multiple universes, just a large finite number before this one for there to be the universe we see today. Just a thought!

Quite the contrary. Life makes a multiverse impossible. Once life arises in one universe it collapses the universal wave function and all these other potential universes chances of existing go to zero.

Humans are very funny, always questioning themselves about everything

What I have never understood about this is why must these parameters be free? Have we seen any of these parameter vary in nature or have been able to force a change in any of these these parameters in the lab? I know nothing about physics, but "free parameters" sounds like a human construct, as if you were building a machine and you build in dials and meters to have exact control over the machine so you have can have the desired outcome you want. It just seems like "free parameters" comes across as an artificial construct, not something that would occur in nature. Are they all truly mutually independent and is there observational data to back that claim up, and what are the bounds of each parameter, and how would you go about changing these values?

According to Wikipedia there are 46 constants ... 2x23 hmmmmm?

How does Carter know we're observers? He must have observed it...

If there are infinite universes, then there are infinite variations of any event to occur. That means there can be a possibility for a super intelligent civilization existing in a universe. Now if we could give ourselves the liberty to imagine that the same civilization has the capability of destroying the complete multiverse and if it has done so, then how are we still alive?

What's horrifying is we would never be able to know what happened to the multiverse or the universe or the earth or the humanity once our consciousness goes away after death.

like a bunch of fish saying, "good thing we were born in water"

I do like to think that our universe is the result of a gigantic super massive black hole collapse by reaching a critical mass. This could seem to explain why outside of the universe seems to be pure dark matter.

No "multiverse" just expansion & conversion" No multiverse. But let's say there where infact" a multiverse!" This universe would be the only one of our kind" There wouldn't be infinite versions of earth but instead.. ............... infinite original universities" where each realm is completely separate & far fetch from the next" but like individual cells multiplying!..... Each cell (universe) is a representative of a nature beyond our comprehension, As the nature of an individual universe is not like how we noticed reproduction on earth, but yet this life form that is reality" is so alien & misleading at it's full potential" (like all women are) Reason & logic just simply falls apart from our understanding. The reason scientists think a multiverse would be infinite versions of our universe" is because like all "cell division" Cells make finite copies of itself in order for whatever lifeform to grow & function.. But! Just because life does this on earth & all around us" Take Notice as to how "the bigger things get! this "notion" breaks down using the law of "Treason by Reason" ...... So unlike the bio molecular system's set on earth" the Universe doesn't create "replicate stars or planets" the Universe doesn't make replicate galaxy formations" if you look closely you can notice the further in time we travel! The more unique & isolated each dimension is from the next & if there is another universe" it's nothing like ours matter fact" this multiverse would convert & transform every universe every distance. One thing for sure! The Universe is Alive 2 things for certain" it is the only true life form as an our universe is every universe even if the multiverse is "real" it is still a layer a pixel a stran of DNA from this mega organism called REALTY. Like the internet" even tho a monitor & computer created tela-communication" phone, tv, video games" etc . . these man-made constructs are still real just not how we would like to perceive them. Ps i wrote this before i watched the video 🤦🏿 The Universe is perfect because it is ALIVEEEEEEE There is no such thing as a life form that doesn't have perfect nature!! For anything to live it must be perfect 🙄🙄🙄🙄🙄😒

Weak sauce.

You forgot the possibility that the universe exists with these constants because it couldn't exist any other way. We can postulate changes to the constants all day long, but there is no evidence that a universe could even form with any of them different from what they are. Nice, simple and clean, with just as much evidence in its favor as the other possibilities.

Are we alone in the universe, or at least in the galaxy? Are we the first intelligent life form in the galaxy? I am just thinking about the "Ancients" of the Star Gate world. If we are the first then we *are* the Ancients. What an awesome responsibility!

Atheists need a multiverse to exist, not life. They're just shifting the problem beyond the beginning of this universe, to the origin of the multiverse. Laws or "constants" , don't come from nothing. The laws or constants of a multiverse or what provides all of those contingent realities with their respective constitution and "constants", isn't "nothing". So it doesn't matter how much effort atheists/materialists invest in running from the non-contingent source of reality (a.k.a God), they will always face the same quandary of having to explain from what and where did all of those laws and energy come from.

We find ourselves in this very unlikely universe because we find ourselves in this very unlikely universe.

What about other universes with completely different rules not just different constants?
