Does Life Need a Multiverse to Exist?

    Another possibility is that the constants aren’t constant, and instead change or are different in different parts of the universe. This would mean if just one section of time or one section of the universe has the conditions for life then life will exist

    life is just the change of universe in time... we're just lifeforms.

    Why do we assume the parameters of the universe could have been anything else? If the universe could only be what it is, there is no need for fine tuning. No need for probability.

    You ever notice something for the first time, then notice it everywhere you didn't before? What if that's the universe? We are it noticing itself, and suddenly it's everywhere.

    The reason the universe has the "dials" is not a difficult question. And we are here simply because if the dials were not set as such, we wouldn't be around to question it and the question wouldn't need to be answered. It's a self answering question. It's the same thing as if my mother turned a corner and never met my father, you would not be around to ask that question.

    As a newly-born Feynman and Overly odd fellow, I Hypothesize the Multiverse is a Tree made of Cubes like Minecraft. An Octree to be exact. Also another valid example of Tesla's 3 6 9 enigma. It is multi-dimensional (3). There are (6) Faces at any point, at any scale. There are 9 points, each face has 1 point at it's center and Face Points Always point inwards(6). Where the Face Points converge is the Center of the Multiverse (7th). You need a Target or Destination, this is the 8th point. The (9th) Point is that you need to Understand and look at things from All perspectives. Perspective Changes and infers to each individual a different Center, and meaning to their own objectives. This also infers the Shape of the Universe, and Why it appears Flat. The Universe is a Cube, a Cube of infinite possibility, chance, and improbability that auto-adjusts in size to what is Observable. When we all get on the same Frequency, diversity suffers as everything becomes one and the same. It takes Less Energy or Computations than it seems, as the Universe is Very Efficient. You can still not comprehend, but, so long as you can Understand this, the Multiverse is Full of both Good and Bad Vibrations. Both Good and Bad Vibes are essential, for one cannot exist without the other and maintain equalibrium. I believe this Also explains the movie "The Fountain" with Hugh Jackman to a Masters degree level. Many times we can over-think the simple, and often forget our Razor, leaving scratchy scruffy whiskers of truth wrapped in misunderstanding. Here is where I leave you with the answer to Everything, Life, and The Universe ... It Cannot exist without Love, so be good Stewards and K.I.S.S. it every moment of every day, and we will all Evolve before you know it. (Keep, It, Simple, Seriously) If you need Tongue, find a Partner who is Willing. If you cannot find a Partner or Partners, Hope fades, Lights dim, and we resort to being Clever and re-complicating things all over again. With this I bid you "Au revoir", I'm going back in the water, it's Warm there, not Cold like most people. Though a Garden would also work, for you reap what you sow, and I think this Hem's quite a few thing together in a neat and simple way. Too bad there is no Prize..I'm pretty handsomly Hangry all the time, could have gone Shopping. Well at least I have my (tau + L)! by me, J.T.P. aka Elroi Jenkies and the Mystery Floor, waiting on an Elevator.

    Remember the Lockers in M.I.B. More or less an example, Also Video games use the Octree for positioning and Tracking.

    Even to say the phrase "fine tuning" is to put the cart before the horse. If a universe had no life we'd be amazed and impressed how fine tuning was just so, so that life doesn't exist. Maybe a universe without life would have something else that's even more impressive than life. Don't put down universes without life. They are universes too.

    As with life n death, forrune and misfortune, we are all lucky to be here let alone question or wonder over it. One thing ive noticed is that as intelligent entities even in isolation from books or knowledge sources, even as a child i wondered all these things, without ever being exposed to the big scientific theories, so are we all Boltzman type brains thinking or working on these problems. Is my simulation the same as yours? Whatever this rambling remeber no religion ever teaches gratefulness for just being, it all seems aimed at whats next after this and i want more life. Be grateful for the immense probablities that had to be in place just for u 2 read my words!

    How can we prove the presence of multiverse? There will be infinite number of them. Just imagine if we change only 1 out 20 free but essential parameters of this universe, namely Planck's constant. Say we arrange a set of universe with Planck's constants spread from 10^100 to 10^-100, say each universe has the tiniest increment of this parameter. That variation set of Planck's constants is already infinite. We haven't talked about the other 19 parameters.

    Some religious people use fine tuning to justify their particular god(s). Another example of religions trying to use our current ignorance as justification for their unsubstantiated beliefs.

    So if I over-generalize, a goldilocks universe is one where energy dissipates at some ideal rate such that stable structures (matter) exist for long enough windows to develop sentient life. Makes you appreciate the vastness of it all :)

    Therefore there must be a Multi Multiverse: there must be lots of multiverses, and our universe is in a "luky multiverse" that has constants. Therefore there must be a Multi Multimultiverse for the same reasons, and so on up to a fractal (multi^infinite)verse. This idea is good on so many levels.

    This will sound morbid but I can't help thinking this way. Even if we are the first intelligent life to exist, someday you and I will die and never know we existed. Further yet, someday all of time/space will cease to exist and none of anything we ever do or did will matter....Makes you wonder what is the purpose of anything? My advise...find something you enjoy doing while you are here.

    I don't agree with the parallel universes theory, it attempts to explain the existence of the universe without God. There is only one of me or you, more you than me though, i am very proud of my creation and the people in it. The time has come for me to act, I realise that you will take at least a year to adjust.

    Ever considered that it isn't the Universe (or universes) the one that is fine-tuned for life, but life the one that constantly fine-tunes itself to adapt to the Universe's conditions, laws, constants, etc? Which could happen samely in whichever universe it might exist, whatever its conditions, laws, constants, etc.? Life is essentially adaptative, and when any form of life can't adapt fast enough, another takes its place. We have seen it and are seeing it now. This hypothesis is like the old Spanish saying: "poner la carreta delante de los bueyes."

    Someone is running a simulation and we are inside of it. Anyone who has ever ran a computer simulation has played with the parameters until they were satisfied with the end results. Our simulated universe is no different...

    This might be a bit off topic: What if in another universe, time is faster than ours, and u decided to spend some vacation there. Would your body age following that universe's time or ours? Im simply looking for some theory based from facts, its impossible to prove anyway haha

    Wait a minute. This totally fits in with simulation theory. Think about it: If human scientists want to find out how ant colonies grow under specific conditions, how would they do that? Let's say these scientists don't just want to study any colonies out in the wild - no - they want to observe as many possible different growing conditions as they can imagine. So, what is their solution? They literally create ant colonies in a controlled environment. The colonies will live in a glass box large enough to reasonably fit any ant colony well beyond its extinction (death of the universe). So, what properties would the scientists finetune in all these different colonies? Well, one colony would get rainfall every five days, and another colony every six days. One colony would have soil with 50% sand, and another colony 51%. One colony will experience a forest fire once every 621 days, and another colony every 622 days. It's preaty easy for us to think of many different conditions which could affect the growth and survival of the ant colony. Now, replace the glass box with a universe, replace the ant colonies with life in general, and replace the growth conditions with the cosmological constants. The human scientists are alien species, creating big bangs in many different (simulated) universes, each with slightly differently tuned constants, in order to observe which universes create life and which don't.

    I'm not sure how the fact that the universe is suited for life is in anyway an indicator that there is a multiverse. I mean isn't this thing that we call life just a symptom of the universe. We were created by this universe in which we live so of course it suits us. We are this universe. If there is another universe with other laws of physics it's whole concept of what we call life will be completely different and they'll be suited to laws of physics of that universe. I don't see how there is anything special about our universe just because we are in it.

    So you're telling me that everything works the way that it does *because* it works the way that it does. And that by changing the way that something works, it would work differently, or not at all? 🤔

    Surely the idea of a finely tuned universe is misleading? This universe may indeed be tuned just right for carbon based life to evolve. So what? If the universe "settings" had been slightly different there would be no life as we know it Jim, but surely with different laws arising from this different universe, life of some other form could arise? Something we wouldn't recofnise as life if we were able to observe it. But nevertheless it would be life in the terms of that universe.
