What is TIME and from where it's originates? What is the "Arrow of Time" ? Why time flows from the past towards the future? Why Time is a Fractal Flow?
Thanks for the fine lecture. I enjoyed it because A) it was presented humbly, without ever leaning one way or another as to which way of thinking is "correct" and B) the historical references gave us a rare view into high level thinking processes with details on how this complicated topic has been debated about over the past several decades. Unlike politics, good science keeps pushing to get to the bottom of things without ever trying to sell anything or preach one belief or another. Well presented facts speak for themselves.
while I agree, good science is exceptionally rare in the real world as it's performed and controlled (funding) by humans and humans, nearly without exception, are run by their egos... particularly in academia 😢 - former research engineer
I agree also, Professor Susskind is so so well versed. I'd really like to see him explain, the way he does, the twin universe theory. With the contention that the black holes actually radiate a force of spacetime faster than the speed of light, a wormhole, to the middle of nowhere between galaxy clusters. Source of the MOND. The matter universe is what we see and the antimatter universe is dimensionally hidden and located in the middle of nowhere. Dimensionally hidden because both universes are created from a very very old universe that is on verge of becoming so unstable that any perturbance wil cause it to biforcate between hot and cold. Ah something like that. A string of energy that twists and pinches off. However it happens, something like pair production occurs with dimensional or hyperdimensional hiding the one half the antimatter half, of the two. universes. Seen from the outside they'd be discreet objects like blackholes. Outside of our universe I'd suppose. These objects and shadow objects, not sure exactly what a white hole is. Are the guide post in a way. The photon sphere has an infinite number of possibilities as does the inverse shadow object, our reality is just one of the possible realities. So like electron shells the universe objects and it's shadow determine not how many different possibilities there are but the range of possibilities there are. So I'd like to see all a avenues of the theory and contentions explored. Including a hyperdimensional frame work that connects blackholes to the empty expansive space and also connects them to the anti universe with the mond explored also. All with the idea that the one universe we see is it. Everything should be in the universe. The resonate frequency need to be fig
However, why is it not true that Boltzmann brain is correct concept that describes the Universe? If it is permitted than how can anyone be sure all perceived isn't a state of that kind of a brain?
@@jchorn7180If a Boltzmann brain existed then the very first thing it would do is recognize its own loneliness and then replicate itself to make another entity like it. Thus: the Hindu Egyptian creation myths, telling of a self-created entity, creating other entities so it can understand itself. We are just the ultimate culmination of that. A single brain can't reflect itself to interpret what it actually is, it needs other brains to be able to look at it. Modern religion deliberately denies the fact that God is both Man and Woman in equal parts.
This was fascinating! Part of it made me think of Thad Roberts (Einsteins Intuition) where he assumed the vacuum was a super fluid. Then, a bubble forms. Starting at this point, while he was not making the same point as David, he derives the constants of physics.
Time is the asymmetry of self-resonance. It emerges from the fact that the universe can’t perfectly cancel itself out, because it doesn’t stop changing.
Could you elaborate more on the ''self-resonance'' part? I am not sure if you meant the principe of detailed balance breaking there? Where time emerges from the fact that "forward" process doesn't get cancelled out by the "reverse" process, due to asymmetry in free energy and work.
@@ayoubsbai6339 personally I believe quantum phenomena are highly self-resonant phenomena - you can think of it like a perpetual Quine if you’re familiar with the computational metaphor. Their self resonance means their spin networks are symmetric and so there is no preferred time direction or spatial connection - these are strongly isolated phenomena which do negligibly interact with their environment. Take a BEC for example, I can cool helium way down and it will liquify before becoming a superfluid. In which case its fermions combine to bosonic states - spins cancel and it exhibits self-resonant wholistic properties. The wavefunction spreads as does, I argue, spacetime itself, which is a highly ‘entangled’ state, meaning one side of the box affects the other immediately. Now heat it back up, the spins begin to misalign, and it starts to behave more classically as the wavefunction exhibits disagreements in phase, allowing local causality to act in predictable ways. It is this environmental interaction that disallows perfect self resonance and imbues asymmetry in the system giving it a preferred causal ordering - ie flow direction in time, simultaneously stitching space together. Like an imperfect Quine that can never catch up to itself as it attempts self-computation (resonance). That’s just my take anyway.
I could add that time is the result of the transition from strong duality to weak duality between the forward and reverse processes. Akin to fragmentation of a mirror into lost parts that can't be, computationally, reassembled to restore the symmetry (or strong duality) between opposing processes.
@@ayoubsbai6339 yes in quantum and classical mechanics, time is reversible -- knowing the laws and the state at any time will give you all other states, forward and backward. time in these models is known as a free variable, and a better way to think about it is actually timelessness. classical and quantum mechanics have no time built into their structure if you associate time with the asymmetry itself experience in real life, ie a directionality or flow.
Religions and philosophies have conjectures re the universe but this lecture explains what we know for sure ( and the various probabilities) thanks to many brilliant physicists. Thank you, Dr. Susskind
It's weird how quantum-mechanics keeps confirming things that spiritual traditions have been teaching for eons and then claiming we only just figured it out, as if we actually didn't know the plain and apparent truth. Agendas make the world work. Question who it is that felt the need to temper access to such information over time.
This brings me again to the idea of time and space displacements being equal. We always have only the eternal existence of "all states"( stealing the idea from Julian Barbour) but it's our brain which can only progress, register, experience with moving forward. It's like a kind of Brownian movement through all these possible states and backward jumps occur but can't be registered.
Whether a planet is orbiting “clockwise” or “counterclockwise” depends on whether you observe from “above” or “below”. Newton’s laws do not distinguish between right-handed rotations and left-handed rotations.
If a reversal of the arrow of time, requires all molecules and particles to exactly retrace their paths… the question arises, would anyone even notice if it actually happened? Random moments could rewind and replay constantly, and no one would necessarily know the difference, or that it had occurred.
Yes, if time reversed, even for a short time, we would notice. In daily life, all phenomena involving diffusion, such as brewing coffee, would take longer and you would wonder why. As you walk you would notice objects moving ahead of you rather than past you without any associated reversal of inertial forces, etc.
That likely depends on whether consciousness is fundamental (idealist philosophy) or an emergent property of the universe (materialist philosophy). If we would notice, then consciousness is likely independent of all matter. If we couldn’t notice, then likely consciousness is an emergent property of matter and would have no way of experiencing the rewind. I tend to be an idealist, and believe consciousness is fundamental, so I hypothesize that we would notice the rewind.
@@karlmiller5009 I think you will agree that movement is not matter and that since movement is relative, gross movement is also *not a property* of any single material object. Nevertheless and self evidently, the existence of matter is prerequisite and necessary for the odd and immaterial existence of movement. In effect, no objects no movement. Put another way, matter is the 'substrate' of movement. If it should actually be the case that thought is constituted from immaterial movement (thereby giving thought its immaterial flavour) we see that matter would then also be the 'substrate' of thought, necessarily. Now, if we compare your brain as you read this and your brain frozen to a temperature just above absolute zero what difference might be found? You say there would be no difference and you find the film, 'Vanilla Sky', logically flawless. Yes?
@@REDPUMPERNICKEL So I have not seen Vanilla Sky. However, I am unsure of your argument. Matter is clearly not the only substrate of movement. Energy, such as light, can also move. What’s more, both energy and matter can pop in and out of existence in space-time as well. So perhaps energy, matter, and relative movement are all emergent properties of space-time. However, even space-time is likely an emergent property, as the quantum gravity research of physicist Nima Arkani-Hamed at Princeton seems to indicate. While there are definitely neural correlates of consciousness, I tend to believe that consciousness is fundamental until and unless we find some other deeper structure from which everything emerges. The universe and everything in it may well be a sort of “dream” or “simulation” of an infinite fundamental awareness. Religious people have seemed to have faith in as much for millennia. Idealism is also more logically sound than materialism. I'd recommend watching the excellent videos from the RU-vid channel, Consciousness Squared. The videos do a good job of explaining the inconsistency of the assumptions made in materialism. I recommend starting with their "1) Knowledge refutes Materialism" video. I wish you all the best.
@karlmiller5009 consciousness being independent of matter is the stupidest popular idea I’ve heard in awhile. Matter is what we are, to say our consciousness doesn’t emerge from it is just backwards. (I say this as someone who's ego death'd multiple times. I've seen and heard it all. It's clear Consciousness emerges from matter as fire emerges from fuel or as programs arise on a computer if you prefer a more complex comparison)
I like the structure of this topic. I have given 20+ yrs of layman thought to time. The universe "is" expanding at the time those light waves that tell us so we're observed. I presently think that time is a Doppler "delay", a predicament of the entire observable universe. That we are in a protective nitch where w/, you might say, a back draft of energy allows conditions for what they call the 2nd law of thermodynamics can be reversed. Phylosophically life is uncomfortable w/ itself because in many ways it is a "foreign", temporary condition.
What if time - does not move - straight - like an arrow - (in flight) ? In India - in yogic spiritual experience - time - takes a spiral shape - let us say, moving upwards. One tends to see/live - the same scenario - again and again but from a different perspective. Until one transcends - as this is the primary dynamic of Yoga - change/transcendence. May it be so/useful. (Fare thee well).
Thats pretty much my software perspective. The experience of all could just be the experience of one. Snapshots of life with past and future relative to your view. Given how basic and often flawed life seems i wonder if were not travelling someplace that takes a long long time to reach.
Thank you - one can research the geometry of the journey - or one may experience it in consciousness - here and now - within the heart. Path of love. Being human - is certainly interesting. Fare thee well.@@luminousfractal420

Actually Time is the distance traveling in the orbit of the circuit of light into matter back into light. God Almighty explains that in the beginning He created light that light turns into crystal specifically tourmaline by photonic geometric structure changing by the frequency of the light photon as it slows in its vortex orbit. After it slows to a triangular photonic structure a faster light photon traversing it loses energy in that step and by the law of thermodynamics the transformation of that lost energy causes the slower triangular photon to crystallize into subatomic carbon tourmaline. It also due to polarization of light creates a dual spintronic force people call magnetism. By spintronic coagulation particles grow all the way into black holes where the particles are deconstructed back into direct current light. God's universe exists as a repeating photonic vortex matrix eddy of alternating current light slowing down in a viable propagation of it's vortex matrix.

This reminds me of an unfinished blog I started several years back, which started with a description of time flowing not in a linear fashion, but like a river with eddies and vertices. Always flowing in one direction but filled with fractal swirls and twists and turns. So I am very pleased to see a confirmation of sorts that I was not just writing a nonsense theory:)

Unfair not to note the speakers name. He presents what we knew up until last month. Neil Turok is proposing new stuff just this week. He's putting it out there. Search for it.
I don't like when people say time is a one-way street but space isn't because you can move in 3 dimensions. Space is as much as a one-way street as time is. You just need to look at it differently. No matter which direction you move, it'll always be a positive distance. You can't move a negative distance just like you can't do something in a negative amount of time. You can't move backwards in space or time. Both are a one-way street.
I grasp only bits and pieces of this. I'm not a scientist. But because it's truth and not fairytale or pseudo science that makes it beautiful sounding. It's calming too.

This is funny because l was just surveying the dismally catastrophic wreckage of my life thinking about how hindsight is always 20/20 yet the future unfathomable. Still l must continue forging onwards through time where many other splendidly exciting disasters await my consternation.
@@marialauraweems7553BUT if one wants things to be alright now or even very good, all they need to do is to simply make a choice. Happiness and spirituality are merely choices, and those never change unless we make that choice, one could live a hundred years miserable or happy simply based on this one choice that nothing physical can truly affect… it’s all a matter of choice and one can make it at any moment, even right now and for the rest of their life. The pudding is in the journey, not about the outcome in the end.
Time is a compactified dimension one single Planck second in size. This is why it sends fractal. Each point in space is in its own phase relationship to time. Like a spinning ball and each point is at a different approach angle or tangent
Self evidently, out of an infinity of possible directions, the instantaneous relative movement vector of a material object points in *one direction* only. Since the concept of time is derived from observations of objects' relative movements, it should come as no surprise that the concept of time has the 'flavour' of directionality. For time (as an actuality beyond mere concept) to be 'symmetrical', all objects would have to exhibit a second movement vector pointing opposite the first one. The impossibility of an object to remain one object while moving in opposite directions, both in 'reality' and imagination, should be abundantly obvious. Time is one aspect of how we think about the totality of objects moving relatively and not a mysterious objective 'something' in the universe. In short, time is a concept only.
One odd thing about the supposition that we are inside a black hole, our visible horizon is due to space expanding, thus making the stars farther apart; whereas the event horizon around a black hole is due to the conformation of spacetime pulling things in a way we call gravity. The reasons for their invisibility to us are quite different: One can expand faster than the speed of light, the other can't. At our visible horizon, nothing special happens. Planets, gravitation and velocity all behave normally; even tho it was billions of years ago - so it might be different in the way matter is clustered, but not much in terms of laws of physics. At the center of our visible horizon, there is no known singularity.
If our physics hints at anything its that the universe is not moving along a path as a whole. Black holes i imagine would introduce horrendous speeds. Or maybe not and that would also fit.
If the universe is infinite, then there is infinite mass outside of our horizon. Perhaps it is this compounding infinite mass which pulls the universe away from us (and light cannot escape it to reach us) But I agree that the universe is completely normal at our horizon and is not different from any other random spot in the universe
Einstiens biggest mistake was riding on the back of e=mc2, which his partner came up with in uni. She wouldnt have been accepted being a woman so he presented it to the world. When she was gone he froze and didnt offer anything more. He never corrected it in her honour. Bit of a git. I suspect the long walks in the snow was punishment by said partner. He did it to go think... About physics or about his relationship 😂
It works better when you have negative time interlinked :) What if we only experienced one side of that coin and there is another flowing the other direction. It made sense in a dream once 😂 (other realm people had learned to control our future from their past, they'd learnt to position their existence against our own to manipulate both. it was quite interesting 😅 their side was kinda red rock and figures that belong in the dark crystal movie)
Interesting. Time does seem to flow according to its vacuum energy multiplied by local values, which would cause time to be expressed fractally. Susskind's theories are growing in my estimation as potential solutions to our current crises in cosmology.
One thing that's mistaken is that the planets in solar system do rotate either clockwise or counterclockwise around the sun. The "-wise" is completely determined by which pole of the sun that you view it from.
You need to apply this logic to everything: direction doesn’t exists, speed doesn’t exists, dimensions are not existent. It’s all just a concepts determined by the “watching agent” in random point of view.
@@fitnesspoint2006 consciousness is the hardest one, but other are just a human constructs too. Anything you can define doesn’t exist in reality but inside your mind model. Our perception system is extremely limited, so we have to quantize the world around as it seems, but it’s silly to call it certain and not probabilistic. Social concepts like free will, freedom, justice, empathy, and others are the most non existant things, but we need to hold to that illusion in order to keep a society as a living organism, at least before there will be another more superior form of life compared to humans.
so basically 1. If the universe never ends, then any form of sentience is almost definitely one that arose from random fluctuation (since random fluctuations happen infinite times if you wait long enough) 2. Any form of sentience that manifests from random fluctuation is almost definitely just a momentary brain hallucinating it's alive, rather than an actual complex life form in an ecosystem 3. If you aren't just a Boltzmann brain then our universe must have an end (to prevent unlimited random fluctuation), but dark energy seems to ensure the universe will exist and have quantum fluctuations forever
Would time be independent of and preceding masses, which cause time dilation? Wouldnt it be directly related to the expansion of space, then be affected by mass; and its consumate energetic potential?
Could anyone perhaps help me understand why in the model of Boltzman of the universe in a box there is a line through the space of possible states and not just random scatetred spots ? In other words, why can't the universe jump from one state through a random and completely different other state but 'evolves' only from one state to a nearby state?
If entropy decreases locally like in your refrigerator, this means that globally, the entropy will still increase. In your refrigerator home, time still flows, and the entropyy is not reversed, just slowed down. You need to reverse entropy for the entire universe.
Then we come to another type of Lambda; with this hyperlambda, we are measuring the ratio of bubbles that spawn per bubble for the duration of a bubble's existence. If it's bigger than 1, then on average each bubble will spawn more than one bubble and the number of bubbles grows forever, if it's less than 1, then eventually existence will run out of bubbles or otherwise hit a finite number of bubbles all stagnant and infertile. Well, I guess the proper way to phrase it would be we would be measuring, if somehow that could be measured. I'm not sure if that leads to any conclusion about the arrow of time though.
Imagine the rebound of the cosmos (the reverse unfolding, or direction of time that embodies the anti-entropy). We are born from the state of death out of the earth/fire/decomposition and make our way toward the mother's womb, and she in turn begins the path toward her mother's womb, etc. Everything combines toward the source, be it life or energy. Contrary to this general pattern...in this "backward-time" direction there is still a split...the fertile embryo of conception splits into the egg/sperm of pre-conception and divides into two entities (the child is the singular entity then splits into the divided source of binary parents). The parents in turn are split into their parents' divided beings all the way back until whether we are splitting or combining gets lost in the mix. If we go backward, we are perpetually divided into our parents' parent's parents...some overlap over the generations I'm sure...and thinking in this backward manner is definitely discombobulating...but maybe I've at least touched on how our perceptions become twisted when attempting to reverse our direction in time as living conscious beings...we consume the symmetry of paradox as it consumes us, and logic/reason is shown to only be a flat representation of the whole picture.
It has always seemed to me that entropy gathers everything into a soup of all that’s needed to make more and more universes. Heat death will happen in certain places but other places will accidently come together.
18:31 Bernardo Kastrup would disagree, I think. 30:22 "When you have a theory which gives predictions which are absurd, you can ask yourself the question: Is your theory right? Your theory is probably wrong." Alternatively, you may have found an anomaly within the current scientific paradigm. Either way, something _is_ wrong with our cosmology. For now, I think I prefer Penrose's conformal cyclic cosmology (CCC), or some variation of it, to multiverse theory. It's all about perspective. However, I don't think of scientific laws as eternal and unchanging. The use of the word "law" is misleading. Everything is subject to change over time, and that includes scientific "laws". However, change may happen over so much time that for most practical purposes they give the impression of being fixed.
"why is time a one-way street when certainly x and y(space) are not one way streets?" They are both one way streets, they both control us(we can't zip through space), but they both give us freedom.
I dont understand how entropy is the increasing in caos if the result is a universe with evenly distributed particles (Heat Death of the Universe). In this case Entropy is the increasing in order, rather than disorder. Can someone explain?
Each universe may have its own set of rules. Some sets may allow further universes with their own rules. Others may not. This may be computationally irreducible. You have to let it play out to know.
Imagine that time is the expansion rate of the 3 D space we live in. Imagine that is the reason why time is the arrow, because space is only expanding and not contracting outside of black holes. Imagine that gravity slows the expansion rate around a mass. That could be imagined as the explanation for the relativity of time, because the expansion rate of space is relative to the position of the observer. Spaghettification is an example of growing entropy but the singularity would be the least possible state of entropy, affected only by Hawking Radiation. Imagine that?
This makes sense in the Minkowvski picture of space time, space is a sphere whose radius grows as r=sqrt(t^2-1): big bang is the sudden explosion (starting at t=1), and then the universe continues to grow asymptotically linearly over time.
Why do nobody wonder where and how time is created. I think there should be a machine. A little like a pendulum clock. The pendulum is not indicating time but it drive the mechanism that show the time. An analogy would be the empty space , it is in motion ( kind of boiling looking very close ) and is the random movement that drive time. Time is indicated by the objects that is influenced by the random movements. So the empty space has no time but just random " noise" coupled to particles that indicate the passage of time. So time is neither quantum nor continous. Another thing is why is physic described using time and not the speed of time or the corresponding noise spectrum?
Perhaps time is a result of things not being infinite. Like absence of light is dark however in the dimensional space. It is the creating segments of “now” that are opposite of space that “always is” or another way to think about it would be if there was no “space” then travelling left or right or up or down would be meaningless it is the creation of space that gives rise to left right up or down to describe that dimensions qualities.
About exponentially expanding universe: Why should there be something special quantum fuzz going on at the margin of an observable universe that is not happening anywhere else in the observable universe? Or is the explanation in that it (observable universe) gets smaller and smaller at ever increasing rate and this margin acts as an event horizon like in the black hole? Still, the observable universe is different for different "observers"; I mean "someones" margin of the observable universe is well inside someone else observable universe...How could there be quantum energy at "someone's" margin while that region is not horizon for "someone" else and that "someone" don't "see" this quantum energy? Anyway, what happens when eventually horizon becomes Planck lenght?
It seems to me that entropy always increases in this universe because the universe is expanding which means there are always more ways to be disordered than ordered, so if you reverse time, you basically contract the universe. I’m not sure why this natural occurrence is being put into question, the asymmetry seems to occur because of the expansion of the universe, which means entropy and dark energy may be related.
Entropy increases due to an expanding universe, as far as we have seen. To extrapolate the eternal expansion would be an assumption. We will not be around to see if that assumption is correct.
@@dadadadoog That simply isn't true, as it's worded. You certainly would not have increasing entropy if the universe didn't expand. Only when the energy density falls below the critical threshold, would you have increasing entropy. So you can say that a continuously expanding universe is not required once that threshold has been exceeded.
@@PrometheusZandskiEntropy and thermal equibilirium, saw decent demonstration of entropy by starting with a table full of coins, all crowns. Run simulation to randomly flip each coin, repeat, and very soon you'll end up in situation 50/50. It doesn't involve space, just property of said space and statistical analysis (well, all coins being similar to eachother etc) in which case entropy does increase but sample size or what they represent doesn't change. Start from very specific -> end up in more "disorganized". More and more precise: search this daily equation from covid-time in yt, I think princeton prof (?) livestreams.
Except, what do we mean when we say a universe that dead ends just dissipates? If energy cannot be destroyed then that still has to go “back in the box” in some way. Then what we would have is over a vast time more and more of these potential universes would be whittled down. Which would have a dissipating effect in itself. There has to hit a point to where you don’t have enough mass to have another fork in the road, no?
Mathematics doesn't provide any limitations of infinite possibilities, so such thoughts are playing with large numbers... but there seems to be a hidden central order (Heisenberg) that LIMITS these possibilities (also of the emergence of new and inderivabl complex systems) - and also such speculations.
6:38 he implies sometimes erroneous, that physics is a 100% accurate representation of nature in the context of your oatmeal. better to say, "our model of nature allows it." that's not the same as "nature allows it" , will do it
I think the problem is.that theories are devised that fail to provide a fundamental explanation of time as an actual component of the universe. This why people find problems paradoxes etc. in entropy, expansion of universe, unification of gravity with quantum. What if time is itself why there is expansion at all, and without expansion there is no time, no space, no particles, nothing. In other words, we need to START with time not come up with somw theory first and then either ignore time or try to fit it into the theory after the fact.
If Carl Sagan was right when he said, "The secret of evolution is birth, time and death," then this way of seeing the flow of time also says there are species of universes and those species are evolving in accordance with Darwinian evolution.
@user-cd2cl7vt7r So a single called organism that is eaten by another does not cease to be itself? Or one that is attacked by viri and whose cell wall is popped is still a viable cell? Or one whose molecular machinery has been damaged by UV light to the point of inoperability is still alive? I get what you're trying to say and it is an important point. But it completely misses the context.
Entropy is a spectrum. Highest entropy is the final disorder which also includes the infinite complexity and infinite symmetry. The transition between the two is the arrow of time
@@RokStembergar I wonder about your thoughts on the gradation between a shrinking/ expanding ruler and speeding/ slowing clock present in every Planck spacetime, the length of time at which no smaller meaningful length can be validly measured due to the indeterminacy expressed in Werner Heisenberg's uncertainty principle.

@@rezadaneshi i'm sorry, but i have no satisfactionary answers for you, while i do understand your question, i am not a physicist 😅 a while ago i embarked on a silly little quest on answering 'why is there anything'. And i tried moving everything into a space of concepts. Where there being nothing (an absolute) draws a line in the sand, and when you have a line in the sand, there must exist something on the other side of it. Perhaps everything. Now, our laws of physics are just a fractal evolution of some simpler, but denser concept before it, which again, i do not understand. But, our universe being just a point in the infinite gradiend, it has some laws that it obeys . I hope at least i can give you some answer, however... What you asked about is what we currently understand. I personally don't see a reason your arguments should be absolute. With new understandings and technology, i am sure those will fractal out into new possibilities :)
@@RokStembergar This concept might help in the future. Nothing but the particle stripped of its duality can get into singularity. Time doesn’t exist so these massless dimensionless charge less particles are everywhere in an infinitely packed space all the time, evident by leaking particle antiparticles into time, right outside it’s event horizon. The gradient stops at fundamental particles so far as we know. Singularity is your “nothing” that can be “everything if introduced into time. Big Bang was such a singularity erupting it’s massless particles that gain mass and charge and momentum the instant they’re exposed to time which in our rear view observation, cause inflation and expansion. Gradient, is an emergent of recombination epoch
@@rezadaneshi but that's the thing, the very idea of duality leads to some fun possibilities, whichever way you look at it. As for the singularity, i just call it the Point. An infinitely dense and the simplest possible concept of anything. I am still trying to figure out what the Time actually is or what is its simplest concept... But i really have a hard time thinking in particles... I want to think in possibilities.
