    Life exists in our universe. There we go - one hopefully uncontroversial statement. Therefore our universe is capable of producing and supporting life. How am I going? Two for two? Let’s try for three: therefore there are countless universes. Hmmm. Did I break my streak?

    Our universe seems to operate according to a set of fundamental rules that we try to understand and model with the equations of our laws of physics. Those equations always include one or more fundamental constants - simple numbers that set the scale for the equation. We can’t determine the values of these constants from pure theory - we have to measure them in the real universe. These are things like the speed of light, the Planck constant, the masses of the elementary particles, and the constants defining the relative strengths of the fundamental forces - the so-called coupling constants.

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.

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?

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.

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.

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.

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.

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.

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.

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.

What there some kind or space mold perhaps or maybe just we came from some fermented space substance.

When faced with the inevitable truth of "perceived reality" most prefer to stay blind. I can't say I blame them.

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!

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?

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.

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.

You forgot the possibility that the universe exists with these constants because it couldn't exist any other way.

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.
