Why is our universe fine-tuned for life? | Brian Greene

[@gamerN77]

Brian Greene is indeed one of the greatest scientific speakers. Wheter you like his ideas or not, you have to admit, he's good at presenting them!

[@jonesgerard]

overTIMe He failed to note a minor detail. The multiverse doesn't evade the strong evidence for design, it actually compounds it. Design is even more implied by a multiverse than a universe. There is no way out for atheists. The way is shut. Come back to the light.

[@vryc]

jonesgerard *Design is even more implied by a multiverse than a universe.* This would only make sense if every universe within the multiverse was complete and fully formed. Smolin's 'Daughter Universe' theory, although not testable, still uses the same framework of basic evolutionary theory and proposes that the many variables that make up a potentially stable universe are not often/rarely met, leading to catastrophic collapse of the vast, vast majority of other universes. The ones that are left over, that are stable, are merely a product of insanely large number survival theory. If, however, we found good evidence that ALL universes within the multiverse NEVER collapsed then I think this could be a solid foundation upon which to hang a possible theistic hat. I think we're a long way off from assessing any of these claims so what's the most honest position to take? I don't know? OR, I know, I believe based upon a really terrible bias and globally recognized ineptitude by people to misconstrue and misunderstand anything to do with probability and large numbers that a god(s) exists? Anyone who has ever taken a probability or statistics course(s) understands just how natively crap we are at these things.

[@jimrussell8720]

jonesgerard So what designed the designer? And what designed the disigner of the designer?

[@johngoncuian4858]

+overTIMe Indeed, he is one of my favorite speakers.

[@alexhartan]

+overTIMe I felt the same way, he sure is a great speaker. My only concern is the content of this speech. There were a huge gap in his argument, when he connected that infinitesimal small number to the fingerprint of our Universe. How exactly did he connect those dots? That was just a speculation on which he didn't spend much time, and that was the core of his talk. I agree that we're in an exceptional position, starting from the conditions of our planet, to the very laws of physics that support our existence. And it's very likely that there are other universes with different laws of physics that would evolve differently. And this miracle is worthy of extensive investigation. But taking that huge leap of faith, just so we can say that we understand our world is not scientific.

[@stratogustav]

This guy is a great teacher. I actually understood everything he said, even the little details. That is a gift, not many can pull that off with these kind of topics.

[@SernasHeptaDimesionalSpace]

[@responsibleparty]

I love the topic and also think he's a great speaker. And, yes, he has a gift for putting things in simple terms (something that only people who truly understand the subject material are able to do). That said, there were still several things he said that I didn't understand.

[@stratogustav]

@@responsibleparty keep in mind that understanding, and agreeing are different things, you can understand something without having to necessarily agree with it, maybe that's what you are referring to.

[@arthurn8952]

if anyone understood this subject completely they would simultaneously be able to fill all the gaps in quantum mechanics and there'd be the 'theory for everything'. Physics would be solved.

[@unRheal]

@@SernasHeptaDimesionalSpace I don't recall any specific stuff he's said, but the above paragraph just leaves me with about 95% confusion. (I understand up to "... seems cool ..." - what does "… on universe knowledge soon will gange (change, I'm guessing) …" mean? Our knowledge of many many things has changed and grown virtually exponentially after ~1900. Then, what does "… we all be joing a better idea we all need of madonas people …" mean? It seems completely senseless, unless you think Madonna's fans are going to save the world for some reason? Finally, what does "… gravity and electromagnetism all seperated will not make it any sistem that you tell me of …" mean? Did I miss something about him theorize separating gravity and electromagnetism to make some system? Regardless, gravity and electromagnetism are already "separated" as much as any other forces of nature are (strong and weak nuclear forces, even electrons self repelling (whatever that's called, maybe one of the two nuclear ones above?), plus the 2 you mentioned. They're separated, but still all part of the same system (our universe) just as the parts of the engine of a car (like that new "1") are separate, but must work together, or it all fails.

@@arreff2012 how so

[@adrianneavenicci]

Me too. Life in its current form literally only exists due to our current climate and environment. If the earth changed dramatically again then some life would die off and new forms of life would evolve to adapt to that new world. It was mind blowing for me to realise this after years of being brainwashed into being told evolution was a lie and life was specifically created as it is now.

[@wrecktifier1]

@@adrianneavenicci , Micro evolution can be proven and shown by science, Macro evolution is just a theory. Until science finds real evidence that one kind (species) can evolve into another kind (species) I will be very skeptical of it. I always keep an open mind, but if they haven't found anything yet, they probably won't. DNA needs a cell, a cell needs DNA/code, information to know what to do, what to become, and how to form. The question is, who or what designer, programer created the DNA code/information?

[@Tony07UK]

@@adrianneavenicci .. wait! You carefully avoided explaining what 'new forms of life would evolve to adapt to that new world' - there's a different process when something adapts and adaptation is not 'evolution' in the sense that different kinds (species) are generated. Even current real world observation does not show that adaptation produces anything new > no new genetic code. Environment does not change the DNA sequence for offspring. Kinds remain kinds - birds remain as birds - cats remain cats, dogs remain dogs etc. > can be proved that all species have genetic boundaries. Modern scientific research proves Darwin was wrong.

Well the interesting part is that when he realised the equations of general relativity pointed toward an expanding universe, he introduced a new idea of a cosmological constant which would be a sort of "push back" force, which could account for the static, non expanding universe he knew he lived in. Except not long after observation showed he was wrong and the universe is indeed expanding, at which point he embarrassingly erased the cosmological constant idea. Then much later even, when it was discovered the expansion is accelerating (like Brian was talking about) the idea of a cosmological constant was brought back in. And while this constant accounts for the expansion of the universe (not the stillness of it) it's still very synonymous in many ways to Einstein's original idea.

I like how he says the question is why our universe is conducive for "our form of life" rather than simply "life". This is because the patterns we call life can be expressed in more mediums than the chemical. Perhaps they could be based on tangled lines of magnetic force, or patterns on the surfaces of neutron stars, or in other mediums we haven't thought of yet. It's easy to think of chemical life as special, so I say Kudos to Brian Greene for correctness, both physical and political.

So to summarize, the universe isn't fine-tuned for life, it's life which is fine-tuned for our universe or else it wouldn't have survived.

[@etheriondesigns]

***** Thats like saying the firing squad was fine tuned for the survivor, because all the people aiming guns at the person happened to miss.

[@Xnerdz1]

davis3d That's a rather simplistic and incorrect analogy. Is the universe aiming at our destruction? Well, certainly in some parts of it we would not survive a day. But in the vast universe with hundreds of billions of galaxies, with uncountable stars, there are plenty of "Goldilocks" zones which can arbor life, and one that we know of has done so 3.5 billion years ago. So to reformulate your analogy: That's like hundreds of billions of non-experimented firing squads, aiming at hundreds of billions of people with a certain among of them who's got the survival instinct of running, and a minimum percentage of guns that can misfire and/or defect bullets. That being so, during billions of years. So yeah... I suppose it's possible for some (or even one) to escape the firing squads alive and then consider his firing squad "finely tuned" for his survival. Is it really so? Was he *specially chosen* or just a selected individual in a random, yet very probable outcome, statistically speaking? Religious people would likely chose the first explanation while rational people would chose the later.

[@etheriondesigns]

***** I am speaking in regards to the initial conditions of our universe. The odds are not in favor of a universe that is capable of supporting complex life, or any life for that matter; which is the very reason why the multiverse hypothesis was invented. I am merely restating the mystery that the man in this video talked about. The analogy fits perfectly when you consider that the universe would have expanded too rapidly or collapsed in on itself if the initial parameters were slightly different.

[@Xnerdz1]

davis3d How do you determine such odds? On what basis can you evaluate how many universes could have worked vs how many that wouldn't?

[@RideAltaTV]

***** Said differently, if you tweaked the forces of elector-magnetism, gravity, and weak and strong nuclear forces by 1 divided by 10 to the 60th power the universe would have collapsed in itself and been destroyed almost immediately or would have grown to quickly and no stars would have existed. (google "fine tuning") So either a creator with knowledge of advanced physics and mathematics made our universe with just the right balance between the known forces to allow for the universe to grow and have everything in it, or our universe is just one of an infinite number of universes with 99.999999 of universes collapsing or growing to quickly when they are created (I know that violates some mathematical laws, but you get the idea). Not believing in a multiverse very nearly compels you to believe the universe was created by design.

[@kokopelli314]

"Fine Tuning" is teleogical nonsense. Asking the "right question" as Brian Greene points out is key to understanding. We, who ask questions, also ascribe purpose and meaning to things, so, to ask anything honestly, we must first identify our hidden assumptions, and then one by one, remove them from their alters. We may, one day discover that the universe, or multiverse is indeed "a communion of subjects", but only through honest inquiry.

[@vitormartins5742]

Think about it. Humans have been roaming the earth for a hundred thousand years, but only a few hundred years ago -- yesterday, basically, in evolutionary terms -- we still thought the sun and all the stars orbited around us. A few hundred years later and we now know of other planetary systems, countless other galaxies, other galaxy clusters even. We know the universe is bigger than we can ever see, because it expands faster than light. We can analyse the microwave background radiation and get insights about the first few instants of the universe (or our pocket of it). Taking this into account makes it very bold to assume we have reached the limit of our knowledge. We've been trying really hard to prove string theory and if we ever get there that would possibly prove the existence of other universes and solve the riddle of the particular values of our physical parameters. It would surely end up raising bigger, deeper questions, though, and that's the beauty of science, we can keep discovering things -- maybe not forever but for a long time.

[@rsanden]

In the words of Krauss [1], "we live in a very special time in the evolution of the universe: the time at which we can observationally verify that we live in a very special time in the evolution of the universe." The Anthropic Principle does not help us here. In a multiverse, it is more than 99% likely that we would have arrived too late to see this, during the static cosmos era [2]. It's even more likely that we would have arrived in a universe "macroscopically different from ours but which would still allow life as we know it" [3]. The Multiverse does not solve the fine-tuning problem, because the real fine-tuning problem is the fine-tuning of discoverability. 99% odds says we arrived very eary -- early enough that we could verify fine-tuning -- intentionally.

[@jeremylindemann5117]

I think there is a distinction to be made here. To say that life is fine tuned for the universe implies that something created life with all the right presets then put it in the universe. That requires a creator doesn't it? It might be better to say that many types of life initially existed but the one that was best suited to this universe survived. But that still doesn't answer where life came from. And still, if all the universes in a multiverse had a creation point then all of their physical laws and constants were determined at the moment of their creation. So it is still an accurate statement to say that our universe was fine tuned for life. So in the end I think one should be inclined to think that the universe was fine tuned for life AND life was fine tuned for the universe. It makes life seem all the more unlikely and perhaps more incredible.

What if the expansion of the universe is due to spin? We know stars have spin, planets have spin, the galaxies have spin... why not the universe? It would be within the established laws of physics. On the outer reaches of the universe, the centripetal force overcomes the centrifugal force and matter flies away from the center. The force at the outer reaches is stronger than that of the inner regions and makes it appear that the expansion is speeding up. The universe also appears to be flat, cosmically. If it was spinning, that would explain how it seems to flatten out. From our perspective we have no point of reference to observe the universal spin because we can’t see it from the outside and everything on the inside spins at relatively the same rate so we don’t detect it. I probably have some of that wrong, but the general concept makes sense to me

I don't think that the universe is cosmically flat. For what i know the universe is an expanding three dimensional sphere. If you spin a sphere you will get a pancake affect which we don't see in our universe. For what we know, our universe is expanding at what looks to be an equal rate at any observable point that is about equal to the distance to where the universe started to explode from, which would mean that the universe is most likely expanding at a consistent rate at any given octant.

[@j-loosenfout67]

In my mind, I don't think we need multivers to explain the perfection of Universe to create life. I think indeed that a single universe is sufficient if it doesn't always exist in the same state. I'm not a mathematician to express this by equations. Yet my theory about this ability to create life is simple. For me all the black holes in the Universe meet at a single point. Easy to understand if we imagine the Universe as an inflating balloon. If you press one finger on each hand on two opposite sides of this balloon and it is not too inflated, then you can have your fingers touched through this balloon by pressing hard enough. It is believed that the Universe by force of expansion will end up being nothing more than a vast ocean filled with black holes and without any visible matter anymore. If all these black holes meet at a single point then the mass of all these black holes combined creates exactly the conditions for big crunch. The ocean (composed of a material that for the moment we don't know what it is - we know that it's not vacuum precisely, but we don't know at all what it is) which contains all these black holes is then in turn absorbed by this immense black hole. Thus the entire Universe then reduces to the size of a point, reaches the second critical point (the famous singularity) which this time creates the big bang. Starting from this principle, the same causes creating the same effects, the Universe would then be a kind of balloon (imagine a heart that beats and that fills and empties of blood with each beat, causing it to swell and deflate) that exists successively in 2 states since time immemorial: Contracted and relaxed therefore. From this beginning of the working hypothesis, we can then imagine that the Universe may not always have been like this. Perhaps, with each contraction-relaxation of this one of the smallest things change, perhaps not even every time. The Universe might have been able, before being the one we know, perfectly calibrated to create life, first experienced states where life didn't appear. Perhaps this life only appeared after billions of billions of passage from a contracted Universe to a Universe in permanent phase of relaxation. I'm sorry if you don't understand what I am explaining because I am French and don't speak English so well. Also, I use Google translation to help me. Can those who have understood give me their opinion on this new way of looking at the Universe? I say that I'm not a scientist at all. But I would very much like to have their opinion on this approach. Maybe, to be more clear and give you a best vision of my idea, for me this famous "singularity", so, exist now, at the same time where you read me. Because all the black holes join in a single point. This singularity is so in development now. You see ? :)

[@rudykrish3869]

This is the concept of the Hindus..they believe the universe is in a constant cycle of creation and destruction(contraction).

[@j-loosenfout67]

@@rudykrish3869 Yes indeed. But for my part, I am not a believer. I'm just trying to logically explain a natural phenomenon. If the Universe is approximately oval in shape, and if black holes have infinite mass; So whatever the size and dimensions of the Universe, black holes are forced to cross at one point. It is mathematical. And if the mass of each one is infinite then arrived at this point of intersection of all the black holes, these cannot cross the ones, the others. Their infinite mass therefore means that at this point, they only form a single black hole bottom. The famous singularity but still in a state of formation, therefore.

[@mightyminotaur8434]

So cosmic expansion is eventually offset by the evolution of black pools of energy we call back holes that will result in a singularity. I find such an idea attractive, however it makes me wonder about the theory proposed by Hawking that black holes actually evaporate due to escaping forms of energy at their periphery.
