This fined tuned stuff is starting to sound a lot like every creationist video out there.

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.

"Life" is not actually a thing. There's no "life" and "unlife". No, really, there is not.

It looks so perfect becose our knowledge is based on our serounding. Just like the 4e demension is hard to amagion but the 3e is well understood. Our logic is puurly based on logic

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.

Can we excite the core of geologically inactive planets and thus initiate a terraforming process?

What is "container" for those multiverses? Can one universe interact with other one?

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.

Life is like when I started smoking: by then, the cigarette was no harmful, neither life needed another place to be.

@PBS Space Time, 4:40, It actually was inevitable for our universe to be capable of life enabling chemistry or else we wouldn't be here and it wouldn't be our universe.

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.

Just think, there is a universe where humanity has created a just and equal world, where Bernie Sanders is president, and where prosperity is based on self-determination instead of greed and environmental destruction. Let’s make this a reality in 2020. Vote for Bernie! 💙

Matter was transmuted from high pressures coming from the living primeval dragon, the breath of life came from the dragon, all cycles dark/light, rest/action came from the fire breathing dragon! oO )

The concept of the Multiverse is not going to be the final answer, should we ever be able to determine its existence (looking forward to your further insights on its testability, as you mentioned), simply because we're going to have to answer pretty much the same questions about that as we do about the Universe. If the Universe exists because of the Multiverse, then why does the Multiverse exist? What made *it* such the way it is? Also, I find the concept unsatisfactory, since, if there are an infinite number of Universes, then everything is possible and nothing is special nor or any distinct worth - there an infinite number of Me, most of which no doubt are grumbling away at their keyboards. It makes the meaningfulness of life neglibble, if not altogether zero, at least from a purely physical point of view.
As for the first two mentioned hypotheses: that we're in a simulation, or we're the "playthings" of the gods, I think we can lump these together, since they are simply cases of existence (life) having an intelligent origin. While skeptics will obviously baulk at such a notion, I'm not convinced that the Multiverse is in any way more compelling or testable.

This entire video seems to be a violation of occam's razor and the mediocrity principle. We don't know there is a multiverse, and if there is then there is certainly no evidence that the fundamental constants, parameters, and laws of this universe are not universal for all of them.
Trying to wade through the slough of imponderables to get an answer seems to be simply an exercise in interpreting the writings of typewriter monkeys.

what about scenario 4, life is very likely/Inevitable to occur in any universe. It doesnt have to be life as we know it but just the bare bones def of life.

Hi, nice but it is almost impossible we are alone in the galaxy, there are just way too many planets similar to earth.
