That's true, but we're constantly getting closer and closer to the truth. *Flat earth* was very wrong, but it explained some basic things; then *Classical mechanics* and modern science explained much more, but was still incorrect in some things. The current *Theory of Relativity* and *Quantum theory* explain all of those things, and are more correct in other things, but still not quuuiitee perfect. But you'll notice we're always getting closer. So it's not like suddenly we can end up with a radically different theory that makes all of former science obsolete.

I love lenny susskind. He speaks so well and has a very clear understanding of things.

He seems like such a sage in his craft.

For anything to be 'surprising' or 'unlikely' it has to be one 'event' that is different in a series of 'events'. We only have and ever will have one example of a 'universe' so have no other 'events' to compare it with so by definition it cannot be surprising or unlikely. He says 'we can only live where we CAN live' - end of story !

This guy once dealt with plumbing and now homes in on the nature of the universe. I once dealt with plumbing and finally made it up to the 17th century and home in on the nature of bagpipes. I love the way this guy forms premises. Of all the possible places, only the few places like have life "like" us.

The design argument is one of the most powerful argument that human being created . But its very deep to understand it in its different way

There's one thing people always forget - these (let's say) 30 constants are not completely independent of each other. It's not like you have 30 knobs on a machine and "someone" sets each one individually to a "perfect" setting and makes them all magically work toghether. One affects the possibilities and the range of others. It's more like 30 people in a line, one imagines a number, tells the number to the person next to them and adds "also, add 1-3 to my number as you wish and give similar instructions to the next person". Many of them are linked and why that's important is that some values EMERGE from the values of others. Some values are not an example of "let's carefully plan this to choose a value - ok, make it 3" but rather "ok, constant x is 8 and constant y is -5 so constant z is - 3". Oversimplification, yes, but just as an illustration. This changes everything enormously, it means you do not have to imagine an "almighty perfect creator" cause nobody else could decide on 30 values to make universe with life in it. It means you may need only a few initial values to be "right" (for OUR form of life), which you have to admit is incredibly different from the other proposal. Imagine baking a cake where you mix flour and water and you have to invent what you'll get and if you imagine wrong there's no cake. No, they do their thing and you get a new third thing - dough. It emerged, you didn't have to create it separately.

If you truly remember your childhood, you will understand that you knew answers to all of these types of questions. The things is that the universe is not accidental by nature but rather incidental. This is something that children see very well because they have not yet been taught all the explanations of whatever timeline one happens to live in.

Easy thumbs up. The most cogent exploration of fine-tuning yet.

I also found that interesting. All of the things that he concludes after discussing the "edge of the knife" are merely speculations that just beg further questions. I find it quite odd how, him being a scientist, puts so much faith in a mere "mathematical possibility" based on string theory. Its interesting how so many scientists hold to this theory that is a mere possibility, without much evidence. Then they are quick to conclude other mathematical possiblities like white holes don't exist.

Kudos to this educator, we need more like him! I'm with him and tend lean toward his 'reason #3', however, listen closely to his last words. "and, a way of populating those possibilities'. So we're back to where we started aren't we? I ask what is the 'prime mover' what started the whole thing?

Life on Earth has lasted for the merest fraction of a fraction of a microsecond in the the time span of THIS universe, and even less in the infinity of universes that have been before this one.

Susskins bio is interesting. Read it!! He was working as a plumber before he studied physics....." When I told my father I wanted to be a physicist, he said, ‘Hell no, you ain’t going to work in a drug store.’ I said no, not a pharmacist. I said, ‘Like Einstein.’ He poked me in the chest with a piece of plumbing pipe. ‘You ain’t going to be no engineer,’ he said. ‘You’re going to be Einstein.’"

People get mad at me for loving this stuff. They don’t want it. I love it. This last year at 65, I’ve been taught quantum physics by our new buddy AI with utubes help. This is exactly where it leads me. This ocupies my mind as I work all day. Good stuff. solution three is inevitable. I’ve number four. God, er no the universe itself is using tests, observation, research, information ect just the way humans do to decide what’s next. It creates a paradox of the unsolavble because the test beds interact. Call it Scott quantum observable quantum paradox, It seems we found the computer code to simulate the universe, organization, but the computer itself is absent. You, your mind and the data, the universe together we create this consciousness so yes it is conscious too solving much. I theorize more. I love it some like it.

So, can any one here tell me why they think the universe is fine-tuned for life, instead of just fine-tuned to produce carbonaceous chondrites? Or methane? Or carbon dioxide? These things are dependent on all the same constants and laws as life as we know it, so why do people think life is *more important* than these other things? Why are they so incredibly anthropocentric? Also, who says there aren't other possible combinations of laws that also allow life, but life not as we know it? Life dependent on other kinds of laws of attraction and repulsion, laws that produce completely different kinds of particles and different kinds of interactions? Why do you think our current, carbon-base life is the only possible form of life?

The water took the shape of the hole and if the hole was different the water would take that shape. What would give me pause is if the universe was made up of different numbers and we still managed to exist in our current form.

So if the pond was conscious and had any sense at all, it should reason that 'hey, if someone used their pinky finger to move a bit of mud from my hole; then I, and the hole that shelters me, as well as any possible configuration of holes that could ever shelter me, would dissappear to nonexistence'.

The universe is simply always "fine-tuned" for the kind of life that can exist in it. EDIT: leonard said it himself that countless possibilities are a prerequisite but he seems to disregard the possibility for countless forms of life and consciousness.

This is a good explanation of the anthropoid principle.

The Universe was clearly fine tuned for death. It is an instrument "tuned" to a sadistic melody. Life for individuals is unimaginably short. As a more general concept, life itself (and planets and stars for that matter) are possible only in a tiny fraction of the universe and for only a relatively small part of the Universe's expansion until it spreads out into an infinitely cold empty void.

Marvelous Exchange. 2 masters at their best. Per the video, there are couple of dozen constants that rest on razors edge, if they were different, we couldn't be here. Chiefly among these is the tiny cosmological constant. We're talking a force with 123 numerical places to the right of the decimal. Nobody knows why it is so small but if it were bigger stars and planets could not have formed. Physicists don't understand why it is so small, but it is curious that this universe is so fine tuned for life. At then end of this video, Suskin makes the analogy that just as there are an infinite way of rearranging DNA do make life forms, so it is with matter. We only see one configuration of matter in this universe, but there may be other universes out there with very different properties than ours.

I let the facts speak for themselves and it exposed complexity that no natural causes could “ create” ...... that’s truly a case for “Naturalism of the gaps “.

Bad Gator the ‘facts’ support all and none religions and are completely supportive in the eye of the beholder. People tend to transform their wishes into beliefs but believing and thinking are two different exercises. Unfortunately, once people are caught up in a belief system they are not longer approachable in a rational way. I confess that I don’t know if God(s) exist but I’m pretty sure that he, she or it won’t have a high opinion from a flock, preachers and pope’s who are so arrogant to pretend that they know what he, she or it is thinking and I’m even more convinced that he, she or it doesn’t give a rats ass about abortion, gays and all matters that make believers wave with one or another religion.

Walter Daems do you believe in objective truth or is your truth good for you and mine is good for me? Does 2+2= 4 in your world? It does in the real world and in every world. This has nothing do for with subjectivity or “wishes turning into beliefs” or I’d totally be following Buddha. Christianity doesn’t make anyone comfortable. Quite the opposite. If calls out what’s wrong in the world and gives a playbook in which to live a moral life by with an objective standard for those morals.

We are fine tuned for physical law. Not the other way around. I like how he was influenced by biological "design space" but I strongly suggest he should use a somewhat more accurate term of recipe, not blueprint, for a variable law universe. Most evolutionary biologists would tend to suggest the same regarding DNA. There is no representation of the finished product within DNA so blueprint fails to convey the emergent effect of simple chemical reactions.

@ErgoCogita

10 жыл бұрын

***** "Technically, the system as it functions via DNA already contains all the possible calculable blueprints/products" You tried to slide the word blueprint right back into a statement that is supposed to explain _WHY_ the word "blueprint" should be used. A blueprint is a representation of the finished product. Nowhere within DNA is there any such representation, in whole nor in part. "But the "tuning" is not in the above... It is, as you've said, in the "effect of simple chemical reactions", meaning - all the Universal constants, all chemical constants, the nuclear forces, the electromagnetic constants of Nature..." That effectively destroys any power in the fine tuning argument as it is used by theists. What is left in it's ashes is an argument for deism. "If the Universe wasn't fine-tuned, then they should be "evolving" in separate parts of the cosmos differently" Your conclusion does not follow from the single premise you gave. However, it does suggest that it is possible that some constants _ARE_ different in other patches of the Universe. After all, if the Universe can evolve/change from it's primordial conditions at different times/places, then why can't some of the conditions be different in disparate patches and/or at different times? Nobody is arguing that they _ALL_ have to be subject to change, merely some. And a little change goes a long way in a causal chain. In the end, I think Feynman said it best with : _If it turns out it’s like an onion with millions of layers and we’re just sick and tired of looking at the layers, then that’s the way it is, but whatever way it comes out it’s nature is there and she is going to come out the way she is, and therefore when we go to investigate it we shouldn’t predecide what it is we’re trying to do except to try to find out more about it. _ -Richard Feynman

This just doesn't seem to be a valid question to me. If the universe weren't the way it is now we simply would not be. For me it is something like we are in the Goldilocks zone of the univers timewise. It's as simple as that. No big mystery. Life takes hold where can. At some point our current universe will not exist. Then there will be something else. Perhaps that something else will be completely hostile to life. Would we then if we were able to perceive that time think gee, existence must really hate us because we are unable to exist here. This place is fine tuned against us...? Anyway you get my point.

The Anthropic Principle implies that this sort of thing is just what we should expect. Not "fine tuning" but the apprehension that there is such a thing as "fine tuning". If you come to it from a theistic point of view the "fine tuning" is there to see. If you come at it with no preconceptions the apprehension disappears. What we can say with some certainty is that the universe is what it is and life is a product of it. Any assumption of purpose, design, fine tuning etc. is guesswork.

+Trent Bell I think part of the problem with this is, without knowing how consciousness and thought themselves work, the best we can say is "We know life of the kind we have in this reality (organic beings primarily made of Carbon, Hydrogen, Oxygen, Nitrogen, etc.) would not exist." Perhaps organic life exists on a knife's edge, but other kinds of thought or awareness as allowed in a material universe do not. This is not an explanation by any means, merely an acknowledgement of the limits of our current understanding. And while it is certainly no disproof, I think it does do merit to weaken the "spookiness" of fine tuning in this way.

These theories come from physicist's extrapolating known laws of physics. None of these ideas were created to figure out anything to do with life (that is a biologist's job, not physicist). Eternal Inflation (which is the main theory that derives a "multiverse"), was created to deal with questions surrounding the big bang. String theory was created as an attempt to answer questions surrounding quantum gravity. None of those investigations are a direct attempt to understand why our universe supports life.
