Is it possible to exist outside of time? Are we just static objects, or do we have to continually reassemble ourselves in order to exist? This is a question that will have to be answered if we are ever to understand the origins of life. I had the pleasure of discussing this with Sara Walker, who is an expert in this field. Enjoy!

Sara Walker is an astrobiologist and theoretical physicist interested in the origin of life and how to find life on other planets. She is most interested in whether or not there are “laws of life’ related to how information structures the physical world that could universally describe life here on Earth and on other planets.

I love the part where they answered the question
She b cute though
Each mo.ment is a new revelation of source.
this is terrific. mostly because dr sara and dr brian have the same personalities, specifically their rather youthful fast talking, like they are full of hormones and have to get it all in, and yet also their clarity and patience with keeping us civilian viewers in mind. i could listen to them all day as there is plenty to think about.
It seems like you can freeze time by moving at the speed of light, and on the contrary mass is frozen, or extremely slowed down light.
Matter is fermions. Light is bosonic. Only the W and Z bosons have a rest mass. If you could somehow slow down light you don't get matter because you still have spin 0 versus spin 1/2 like electrons. This is a very important distinction because it is the difference between something like a laser where everything wants to be in the same state and something like a table which is solid, where the electrons can't "get on top" of each other too closely (the technical name for this is the Pauli Exclusion Principle)
5:34 "you have to go through 4 billions years of evolution to get an object like me". Worth it.
Thank you, great talk.
Our pleasure
She's hot and intelligent. She must have some serious flaw hidden somewhere surely!
I agree, she is cute, but worth 4 billion years cute?
Cute, but cute enough to ignore that she apparently has no real idea what a quantum fluctuation is?
You are quoting her essentially saying physicists don't understand quantum mechanics but she does, seemingly based on a misinterpretation of the very ideas she is presenting...
@@jyjjy7 I believe Walker is suggesting is that complexity must originate from some form. A potted plant can't be born from quantum foam alone.
I think of "Constructor Theory" and I think of structures (world lines) in Spacetime as opposed to the view of things isolated in a discrete time slice of Spacetime. But a world line is static in the past, only active in a local present, and any meaningful present is not point like but extended, with various interacting components, each embedded in their own local present. That makes for a pretty complicated picture of evolving structures. But it isn't even clear what it might mean to say that a world line is static in the past. I look back in time to a distant star and say that the world line of that star is static in its past, but as I gaze at that distant star's appearance, in my present, it has an influence on my thoughts and feelings, so how static IS that distant object's world line?
Fascinating, where is the full conversation?
Apart from time could there be an ‘unknown’ driver for change something that is part of physical matter? Thoughts are something. thought energy can change physical matter and is part of it. Time stays emergent this way.
Might be better to think of that as there is an amount of work done by entropy into an object, not time. Very interesting though. Maybe we can even set a spacial name for this term - the amount of entropy work that has been done for an object to acquire its specific characteristics.
I’m not sure the stasis question is that difficult to answer. As an analogy, you can pour water onto a sponge (water being the analogy of time, the sponge being the analogy of an object). That sponge will get heavier and heavier (weight being analogous to information / evolution) until it is saturated (analogous to reaching pinnacle of evolution ie a professor!). At that point the sponge won’t soak up any more water (time), but that doesn’t mean you can’t pour more water (time) onto it or that water (time) ceases to exist. It just means the object is saturated with time and additional time doesn’t = additional evolution.
Cosmic radiations has a biggest role in formation of life on earth not only water and other chemicals. Cosmic radiation which also flips bits in computer creats glitch and error or genrate output with wrong answers in computers. Abiogenese is a complex and time consuming process and cosmic radiation has played big part in it.
Pinnacle of evolution spontaneously fluctuated into existence 🌱
I'll need a citation on that agreed property of Time being an emergent phenomenon of reality as opposed to a fundamental part of it. When we reach that particular bridge, I will be more than happy to cross it with you on the journey of exploring your idea. I've been thinking about Time for decades. I have no damn clue what it really is, even if it *is*. It isn't so much my knowledge on the subject that has grown as it is my ignorance of it. The more I learn, the less I know. Frustrating eh? But if it were easy, one of the plethora of more intelligent people than I would have solved it by now.
Here is a clue. Time is that which separates events. Now you can continue your decades long thought process with a fairly obvious clue. Einstein gave another more subtle clue, time is relative to it's own inertial reference frame, so that which separates events in your reference frame may be compressed or stretched in another reference frame. I just thought up somewhat more obvious clue: within your reference frame, cause will always precede effect.
What else can I think of... I heard something called a Zen koan about a man that put up four walls and a roof to make a cozy little room for his family. The walls and the roof are not the room, but without them is there a cozy little room? Well, yes and no. The room might be there, but its really indistgishuble from any other space and therefore wouldn't be very cozy and his family might get cold in the rain.
Maybe time is the same way, where events, cause, and effects are analogous to walls and roof of the cozy little room. Without them, would there be any time? Sure, but without any events to be separated, would there be any time? Here I might say again, yes and no, but consciousness as we understand it, may need time to change. Change implies time, perhaps, and consciousness seems to always be changing and evolving.
Oh cool, Sara is awesome!
Beautiful 🧐
This is the first time I've seen and heard of Sara. I saw her image before hearing her speak. Boy, first impressions couldn't have been more wrong!
What do you think a thought experiment is, but existence outside of time, except when needed to satisfy ordered thought dependencies?
My understanding of emergence comes from Brigitte Falkenburg (Why More is Different, Falkenburg, Morrison eds, 2015) and involves amount, but emergence within a process would indeed be time based.
I thought biochemistry evolving from geochemical and geophysical cycles was self evident hehe
Sara Imari Walker R0X!!
Does she work with Lee Cronin?
Time is abstract, not fundamental - its how we reference change. Change (including the subset motion) is fundamental, and reference-frame (e.g. quantum) specific. And all change is caused by energy differential. If you are not changing (in a particular reference frame) then you are static (in that particular reference frame). There is no universal time 'thing' ....just quintillions of change events. Look around you.
Although it might be naive, I have always imagined time to simply be any change that occurs from one state configuration to another, admittedly an idea with little to NO explanatory power.. Leaving the time element aside, the specific issue involving information processing which leads to proto lifeforms and then microbial life, that idea IS convincing.. So is the position that an emergence in complexity arises in direct relationship to the AMOUNT of information processing within proto and actual lifeforms.. One could extend such arguments to suggest that the very same principals apply to, AND enable the emergence of all complex life including ourselves..Yes?
This is why people get the collective mindset. They buy into the lie that no one is an individual.
I’ve come to believe time should be thought of as a 3D space with axis of harmony, logistics and existence.
0:03 intuitively I say there has to be. Like any form requires conciousness to power itself for existence- existence/conciousness/god is truly infinite and your tiny little mortal mind can’t possibly grasp the concept or is finite and expands/contracts/remains static in relation to how much physical manifestation THEY choose to create (all life and the universe) for the purpose of aesthetics, for fun and contemplation.
6:07 daily grooming - I admire the people go out any way. They may be depressed, they could be the Clint Eastwood of 0 fucks what anyone thinks, because you are comfortable going through life without a mirror. Pure experience. Of course those people who make a production before stepping out are such works of art transmuted into a form of personal aestheticism…. which is a spiritual practice in the south and eastern religions.
7:02 On spontaneous Lorentz transformations:
the asymmetry of time actually implies the accumulation of time, more precisely, history, variety, aging.
Instead of the Copenhagen and/or multi-world interpretations of quantum mechanics, the presence of spontaneous Lorentz transformations seems to be more physical.
“Summarizing, we can say that the postulate of relativity includes the statement that the uniform and rectilinear motion of the "center of gravity" of the Universe relative to some closed system does not affect the processes in this system." (Pauli, RT). Obviously, for an expanding universe, the opposite is true.
Apparently, the researcher can detect and measure the effect of the aging process in his own frame of reference caused by the phenomenon of global time t(universe)=1/H: ds^2=c^2dт^2=g(00)c^2dt^2=(1-Ht*)c^2dt^2, where the Ht* parameter
shows which part of the global the time "elapsed" in its own frame of reference, t* is the measurement time according to the clock of the resting observer, t is the duration of any physical process in its own frame of reference.
That is, an observer can measure the increase in the duration of processes in the laboratory frame of reference: dт=[√ g(00)]dt=[√(1-Ht*)]dt~(1-Ht*)dt
What about the chirality proble what about the polymerization problem? What about the fact that peptide chains don't form in aqueous solution? These things and others are pretty much fatal to the idea of assembly theory, and abiogenesis in general.
Well, you just remove time and throw in an infinite number of rolls of the dice, and problem solved. The more time passes, the more I respect condensed matter and experimental physicists, who actually produce results.
the problem with theories are they are thoughts and your thoughts are not your own
if you think they are try turning them of
📍4:55
Ok so it’s ludicrous to expect scientists to make a cell in the lab.. how about just explain why the DNA code exists, why, how, what were the early stages/events that led to it, evidence, experiments, etc.. the BS that is out there now is the best we’ve got? Not convinced of any natural explanation presented, they all must be admitted to be ludicrous based on what we understand.. so difficult for people to just admit they don’t know and haven’t got a great clue
Where does time come from?
If 2 or more things can move relative to each other then there is time.
Complexity should increase over time in a system if matter-energy is added.. Once energy input stops the system will simplify over time... Redefine 'entropy' this way:
ENTROPY: simplicity. Closed system complexity reduces over time. Uniformly (dis)ordered (hot)/cold field is simplest
There are islands of high entropy stability that can be highly ordered, not just disordered. It's more about uniformity. a gas in a uniformly random state is much the same entropy as a solid crystal/metal ball in a shielded, closed box in the middle of a deep intergalactic void in this model. Nature should make use of regular structures such as polymer chains and sheets.
What could that even mean?
Replace the word Time with Entropy, and everything would be much clearer. The transformation and transfiguration of materials all take place in the Present, not the Future or Past.
So living systems have a separation of data from machinery and non-trivial replication.
How about time only occurs when you're violating the 2nd law of thermodynamics.
This is great framework breaking down dualistic notion of inderect & directlines of measured wanting emphasis on the in-between but still wades in the water with boots on like most of physics.
. It's a well used formula that can & has been a zeitgeist used in many different industries..it doesn't tell us anything but doese count some routine patterns in biology but it's shared in other things as well.
It's taken physics along ( time ) to accept things and even still it's elders are reluctant..but it only makes sense the most hard headed dicipline of all has the last desperate hail marry attempts.lol
I like computational selection theory but it is in direct opposition to darwins ideas.idk why you would limit it to a singularity at this point..
3 way transfer & exchange of data was used against evolution and was the advocacy predictions. So much was predicted in the great debate to be true that If the darwins movement listened then the Swedish discovery of dna then wouldve been the starting point of modern biology instead of fighting against all the gallaleo conprencous discovery along the way.
To have made religious vs science claims against the very creators of our methodology was always wrong. Textualy Inspired methods in concert with orientation and direction has always given many great predictory power to certain generations but it was so combative it simply became an echo chamber pushing away those generations and only filling itself with ptolemaic Minds.
It doesn't matter how ideas ,models come about all that matters is if it is truly predictably repeatable facts about nature. Your can confirmation bias correlate anything after the fact.
Like it or not what was predicted
If earth did exist closer to the center of the milkyway during an active galactic nuclei era it would be something absolutely perfectly aligned in a way that would be very difficult to repeat even in the expanse of the universe with many trys.
We do need a point where we say the most funding in human history the last 90 years , that for 500 years a movement born in reaction to discoverys made inadvertently becomes our chosen goals and the grand unified evolutionary singularity in all feilds over time doesn't make or break anything.
Physicists discover that biology takes time. Let' call it Constuctor Theory Must be a Nobel Prize there somewhere.
There is no time itself just continuance
I think I understand what she’s saying, but it was devoid of any explanation, evidence, or experiment as to HOW WHAT WHY life
She has what I call faith-based science. Start with the faith in an idea and slap some math and sciencey stuff around it. It's the sort of stuff that is making theoretical physics cringey.
Nonsense I say Nonsense
The theory appears vague, information implies an ordering process which implicates "design" and you end up with a variant of "mathematical creationism". Direct, or even indirect evidence (cf particle physics) must be subject to a valid measuring strategy. I cannot see how this theory can ever become meaningfully quantifiable. In reference to religion (designer, creator, spirituality in general) Buddhism I would suggest is superior. And I am not religious!

The Age of Life
The ability to carry out actions differentiates inanimate matter from living matter. In turn, every action involves the management of Information.
We do not know what Matter is or what Life is, and we assume that all life forms that currently inhabit the planet descend from a common ancestor (LUCA), an organism whose complexity is evident if we consider that it is attributed the ability to reproduce. Due to the above, it is reasonable to assume that “seeds of life” existed prior to LUCA. Assuming that the “seeds of life” emerged together with the Big Bang is a bold postulate, and as such requires a solid empirical foundation. When observing Evolution considering the information that our ancestors have managed, and that currently managed by humanity, it is possible to distinguish seven evolutionary milestones; Its analysis allows us to postulate that Life goes back to the origin of the Universe, and the existence of an “evolutionary pattern” is evident, which turns out to be the Golden Ratio.
Evolutionary Milestones
-Emergence of ”Seeds of Life”(1) (thirteen thousand eight hundred million years ago).
-Emergence of LUCA (Last Universal Common Ancestor) three thousand eight hundred million years ago
-Emergence of the brain (five hundred and fifty million years ago).
-Emergence of what was the precursor of human language (2) (twenty-seven million years ago)
-Emergence of the language that characterizes us(3) (around two hundred and twenty thousand years ago).
-Emergence of “the information age” with the transistor (1950)
-Evolutionary Singularity(4) proposed by Ray Kurzweil, who postulates that humanity will access a Singularity as a result of the exponential growth of information management (year 2045).
Evolutionary sections
Among successive evolutionary milestones we can distinguish the following six “Evolutionary Tranches”, with the duration indicated (in years):
Tranche 1: 10,000,000,000 (13,800,000,000 - 3,800,000,000 = 10,000,000,000)
Tranche 2: 3,250,000,000 (3,800,000,000 - 550,000,000 = 3,250,000,000)
Tranche 3: 523,000,000 (550,000,000 - 27,000,000 = 523,000,000)
Tranche 4: 26,780,000 (27,000,000 - 220,000 = 26,780,000)
Tranche 5: 219,905 (220,000 - 95(5) = 219,905)
Tranche 6: 95 (95 - 0 = 95)
The particular variation experienced by the Evolutionary Sections over time suggests using the logarithm of said sections (LT) to analyze their behavior over time. The logarithms in question are as follows:
LT1 = 10.0000
LT2 = 9.51188
LT3 = 8.71850
LT4 = 7.42781
LT5 = 5.34224
LT6 = 1.97772
The lines between two successive logarithms have the following slopes (P)
P1 = -0.48812 (9.51188 - 10.0000 = -0.48812)
P2 = -0.79338 (8.71850 - 9.51188 = -0.79338)
P3 = -1.29069 (7.42781 - 8.71850 = -1.29069)
P4 = -2.08557 (5.34224 - 7.42781 = -2.08557)
P5 = -3.36452 (1.97772 - 5.34224 = -3.36452)
After searching for an “evolutionary pattern” we will determine the variation between successive slopes, which is given by the Ratio (R) between them, that is, P2/P1; P3/P2; P4/P3; P5/P4, and is the following:
R1 = 1.62538
R2 = 1.62682
R3 = 1.61586
R4 = 1.61324
The above values differ from the Golden Number (1.61803), a number also called the golden number, the number of God, the extreme and average ratio, the golden ratio, the golden mean, the golden ratio and the divine ratio, by 0.45%; 0.54%; 0.13% and 0.30%, respectively. In turn, the average of the sum of the ratios is 1.62032. This value differs from the golden ratio by 0.14%.
The results obtained allow us to postulate that Evolution follows a pattern that is a function of Information and the golden ratio, and that Life goes back to the origin of the Universe.
Knowing the evolutionary pattern, it is possible to project the duration of an eventual seventh Evolutionary Tranche, which turns out to have a duration of 2.99 hours. The above allows us to postulate that humanity will have to face a Singularity, with an uncertain prognosis.
(1)The last universal common ancestor (LUCA) is the putative common ancestral cell from which the three domains of life, Bacteria, Archaea and Eukarya, originated. The complexity that LUCA is assumed to have does not give rise to affirming that it arose by “spontaneous generation”, it being valid to postulate the pre-existence of “seeds of life” prior to the emergence of LUCA; It is postulated that the origin of the “seeds of life” dates back to the moment when Matter arose in the Universe, that is, around thirteen thousand eight hundred million years.
(2)“We find that the anatomical potential to produce and perceive sounds differentiated by their formants began at the latest by the time of our last common ancestor with Old World monkeys (Cercopithecoidea) about 27 Ma ago”; " Which way to the dawn of speech?: Reanalyzing half a century of debates and data in light of speech” (Science magazine)
(3) The last change in the position of the hyoid bone in humans, which would have allowed access to the language that characterizes us, took place approximately two hundred and twenty thousand years ago, and its data is based on archaeological evidence and anthropological studies. There is no scientific source that records this change on an exact date.
(4)Due to the exponential growth of information technologies, Ray Kurzweil postulates that a Technological Singularity will occur in the year 2045, at which time technological growth will be so rapid and so profound that it will be impossible to predict what its consequences will be.
(5) It is the time between 1950 and 2045, the latter year in which Ray Kurzweil postulates that a Singularity will take place.

These days we are hearing much of philosophy and philosophising rather than actual science. A real breakthrough in Science takes huge time. Meanwhile, philosophising about plausible and possible ideas are thrown around that's the state of science now.
She reminds me why theoretical physicists should be unemployed, or at least employed as science fiction writers. They take ideas that can never be proven and are prima facie nuts and apply math to them to provide some veneer of respectability.
she's effectively asking if there is life in singularities, since time is nothing but motion itself
singularities ain't real
everything is a quanta, an oscillation amplitude
the universe is a quanta, too

We don't even understand time itself.
Please tell me what does that have to do with anything in this context ? (I mean I can say we still don’t understand gravity-in terms of why it works)

Is There Existence Outside of Alcohol? Johnnie Walker
Hahahahaha
All the wonky grandiosity of ludicrous hypotheses that necessarily MUST arise when people WILL NOT accept the plain fact that the Universe was created IN six days, roughly 6000 years ago.
For sure, one has to deal with the question of HOW can stars be zillion light years away in a universe just 6000 years? But this is a question that can ONLY be even begun to be addressed once one has settled in ones mind that the universe was created by a supremely maximally intelligent being.
The trouble is that if he indeed is the one who designed and created the universe then I have to forgo bragging rights for our supposed theories. And it is precisely this grandiosity that internally-arrogant but externally-pseudo-humble people just absolutely chafe against.

What a bunch of hooey! Look at the work of Michael Behe and irreducible can complexity and you realize that information is the underpinning of life (DNA and.more) and wherever you have information you have mind...mind supercedes matter and life.
I think when she says that it takes 4 billion years to make a Sarah it's a way overcomplexification... multiple Universe versions allows for infinite different versions of Sarah to be mass-produced and small differences exist in Mandela effects which the simulation does the best job it can...
Due to the uncertainty principle it rules out a static universe...
The probability of life developing on what was a molten surface in maybe 300 million years (or less!) after it cooled down, is pretty nearly zero. I would go for panspermia.

I heard a lot of philosophical daydreaming there, not much science.
The computer you are watching this podcast on, has its created functionality as per code. 1 and 0 at the lowest level. No matter the sophistication of programming languages on top of it, no-one in its right mind will claim the functionality fell from the sky like mana. If it has code, a human programmer was at the basis of it all. Period. A living cell has at its core DNA, (double RNA). Thats also CODE. A 4 digit code ATCG. Why cant we accept likewise that if it has CODE then it must have a programmer. And it wasn’t us. So there must have been a creative force whatever you may call it. One might make a dictinction between the actual programmer (maybe not as devine as we think) and the creative force ruling all. We humans currently are afraid what we created with our binary code (AI) may surpass us in some functionality and what to do with it. it is not illogical for whatever created our code to do the same.
You anthropomorphizing the act of creation. It's SUCH a basic and common human error... I'll just say I'm disappointed in you and leave it at that.
