[@marishkagrayson]

Exactly. The future is in a quantum state of superposition. The past is classical, it’s already decohered and is now subject to thermodynamic decay and dissolution of order into an increasing entropic state:. The only thing that is “real” is the now; when we (a collection of events) interact with our environment in a process called decoherence. Time, and therefore the now, is relative and only real for the events that have the strongest interaction which is communicated at the speed of light. The notion of a bulk universe where the past, present and future are equivalent may only be real for a photon which does not experience time. Its lightcone must seem like a single instant when past, present and future all exist at once: We, as confined energy, do experience local time because we are in respective gravity wells which slow down spacetime and give us a sense of now, which for distant observers could lie in their future or their past. Btw gravity wells are not a technical term but a good visualization. I suspect they are, in fact, force carriers called gravitons( negative pressure) which weakly bind matter/energy. Thermodynamics and thus the arrow of time are governed by the mysterious dark energy which exerts positive pressure and expands the universe.

@@lucienberl He is also one of the smartest people himself, so I guess it was only a matter of time. No pun intended, because I'm not as corny as dr. Greene is, but I guess I can honour him by letting it slide this time :p I do think that it helps a lot when a host actually understands the subject matter and also knows where the difficulties are for all the different people who are listening by having lots of experience with asking questions and listening to people asking questions as a teacher. I think it's too simplified to just say it's good to have a physics teacher on the stage because like students, all teachers are different as well. I think that dr. Greene has a very good mixture of the most important components that make him such a great physicist, teacher and host. 10 years ago I had my doubts and I thought he just liked the limelight a lot and dumbed things down too much after already having made several videos on the same thing and having done several talks, saying the same things over and over and I grew up. I now understand why he does love the limelight to shove his love for physics in. He loves people just as much and he loves nothing better than to see the same enthusiasm for science in others that he has as well and share it with the world. And sure, he's vain and likes the attention and he finds himself very funny, but can you really blame him? He is one of the, if not the best science communicator of our time and I think he knows and is comfortable with the fact that he's such a dad when it comes to jokes and we laugh at least as much at him as we do about his dad jokes :p I'm glad I'm not his kid; I'd be embarrassed as fuck but also very proud and happy to have him as a father.

[@Justinehumanity]

Kalapi Trivedi - Prior to this talk I didn’t quite get the ‘reality’ of how concrete and time-bound the thinking of many very intelligent people is. This helped me understand more about why my ideas are often dismissed or laughed at by respectable academics - and why it is so difficult to find a shared language to describe how I personally intuit things. I’m certainly not brilliant, but am one of minority of people who often experiences life non-linearly and tends to frame everything in a very abstract way. It was a huge problem in school and confusing to those around me growing-up. This all prompts me to wonder how many people who intuit time as fundamentally linear and concrete, were in any way affected by this information. My hypothesis is that time perception is a fundamental ingredient in the diversification of human personality; hardwired and perhaps, insurmountable.

You might work for a company that regularly postpones meetings causing you, through habit, to interpret that phrase as referring to Friday, or vice versa.

From what I heard she wasn't even making any such claims that you suggest, they were having a conversation and she gave examples of what are the possible interpretations of time in different languages. That being said The notion of when things are happening is a fundamental portion of information that needs to be passed over in any language, so how that information is passed on in your spoken language and what images are constructed in your minds eye when you interpret time passing is also fundamental to your perception of time. The fact that learning a language is one of the first things you do to help you communicate information means the language you learn does in some fundamental way help you construct your ideas about how the universe operates . That doesn't mean those perceptions cannot be changed, you can learn other languages which will open your mind to how this concept works in other cultures.

@@VI5H my qualifications are more than enough to identity that the sheer magnitude of the experimentation required in order to isolate all other possible explanations for why people interpret ambiguities the way they do so as to conclude that a certain mental state is the definitive explanation is beyond the scope of the current state of understanding in the field of psychology. The fact, however, that you immediately defer to "qualification" just shows the kind of thinker you are. Uncritical and wowed by the bells and whistles of a system accepted without criticism or critique. Qualification is no guarantee of anything, evidence and reason stand for themselves and it's only there that you will find what's real.

Still, that entropy... it just didn't stop yapping, shouting in my ear: "Without me, it is all just academic! An exercise in mental gymnastics! L'art pour l'art!

Time, often thought of as a linear progression, reveals its true complexity when viewed through the lens of quantum mechanics. In this realm, time is not just a ticking clock but a dimension deeply intertwined with the fabric of reality itself. The quantum mechanics of time challenges our everyday perceptions, suggesting that the past, present, and future may coexist in ways we can barely comprehend. At the quantum level, particles can seemingly move backward in time, or exist in superpositions where multiple timelines unfold simultaneously. This richness of time reminds us that our classical understanding is just one perspective a simplification of a far more intricate and mysterious phenomenon. It also raises profound questions: Does time flow, or is it an illusion created by our consciousness? Could our actions in the present influence not just the future but the past as well? Exploring the quantum mechanics of time doesn't just expand our scientific understanding it invites us to reconsider how we live within this dimension. Perhaps time is not a resource to be spent but a medium to be explored, a connection between all moments that allows for deeper insight into the nature of existence. The richness of time, at its core, reflects the beauty of the universe's underlying complexities.

As I see it, time is merely a degree of freedom that allows change to happen!! Time is not synonymous with change. If you have three Petri dishes and 1 hour of time?? Of each Petri dish contained three kinds of bacteria with varying speeds of replication?? Within the span of 1 hour you would have differing rates of change in each Petri dish?? Of course these rates of doubling are in no way fundamental in nature but it does effectively show the distinction between time and change!!

[@nmikloiche]

Time and I have an odd relationship. If left alone, with no obligations, I am at my most happiest. The reason is that I have ADHD and with that I suffer to process time “normally”. This time blindness causes me so much anxiety and takes up so much room that I have little cognitive energy for being in that state of flow. It is painful and embarrassing to admit or show how poorly I estimate the amount of time I’ve been doing something, or predict how long it will take me to do something or arrive somewhere. I’ve created cues to help me, things like timed reminders, but even with them in place I can quickly dismiss them and loose track of time. I am endlessly aggravated about this, how is it that I can’t fix this about myself.

Might the "now" moment be how decoherence is expressed in the time dimension of space-time? So, in space we experience solid matter (as opposed to the wave it emerged from) and in time we experience the "now". The implication would be that time is emergent from mass, not fundamental. Also, the arrow of time would therefore be the result of our continuously expanding universe, which in turn "stretches" all matter, which in turn generates a continuous flow of new "now" moments. Another implication of this way of thinking is that entropy is the result of our expanding universe.

[@lancewedor5306]

So, when exactly is Now? I am baffled, perplexed. Aarghh!

[@carlkligerman1981]

My feeling has always been that what we are experiencing as time is simply one enormous and yet brief moment, that we arbitrarily divide in units of measurement to grasp.

[@ReverendDr.Thomas]

🐟 05. THE PHENOMENAL UNIVERSE: As demonstrated in the previous chapter, there is insufficient evidence for the existence of a separate, objective universe, external to the perceptual faculties of a conscious being. The fact that the phenomenal universe (“prakṛti”, in Sanskrit) of mind and matter (or name and form [“nāmarūpa”, in Sanskrit/Pali]) exists (that is to say, is perceived) solely within the personal consciousness of any individual human or animal, is superlatively logical. If this material world actually existed as a SEPARATE reality, then obviously, it would have limits, because the nature of matter is that it has a measurable, three-dimensional finitude. Despite what some may claim, no perceived object can be infinite or eternal. Therefore, if one were to travel to the edge of the universe, there would need to be something WITHOUT the boundary of the universe (some other “universe”, which contains this universe). This contradicts the very concept of a universe (literally, “turned into one”). Therefore, there cannot be a so-called “multiverse”, for if it were so, the summation of all discrete universes would properly be termed “universe”. Our observable universe would then be merely a “cell” or “bubble” of the totality of material nature. At what location did the universe begin to exist? The late, great Professor Dr. Alan Watts’ response to the question: “where is the universe located?” was: “nowhere and everywhere”. One of the most misunderstood aspects of this space-time universe is just that - TIME. There are various extant theories of time. However, time is a very simple concept to grasp for one who has experienced his own timeless nature. That usually occurs during meditation practices or during awakening experiences (see Chapter 17 to understand spiritual awakening). Possibly the easiest way to understand time is to use the analogy of a movie. It may take a couple hours to watch a motion picture, yet the whole film is contained in the form of a single digital file (or in the case of older mediums, a reel of photographic film). The story of this universe may take hundreds of billions of earth years to complete, but from the perspective of eternity (literally, “no time”) it is not even as long as the blink of an eyelid. Indeed, it cannot be measured at all. To use movie jargon, the story of life is already “in the can” (of film). Read Chapters 08 and 11 to learn about causality and predestination. In practical terms, time is witnessed by phenomenal changes as perceived by the faculty of memory (i.e. time corresponds to change). This material manifestation is composed of space, time (or, to be more accurate, space-time), energy, and matter, the latter of which comprises eight elemental groups - the five GROSS elements (“mahābhūta”, in Sanskrit), which are perceivable by at least one of the five senses, and the three SUBTLE elements (“tanmātra” or “atisūkṣma mātra”, in Sanskrit), which are symptomatic of localized consciousness. N.B. Dark matter and black holes are not included in this system, as cosmological science has yet to determine their structural composition. The five gross material elements and three subtle material elements are (from most palpable to most intangible): SOLIDS (AKA earth - “bhūmiḥ” or “pṛthivī”, in Sanskrit) are made of densely-packed molecules of a steady shape at room temperature. LIQUIDS (AKA water - “jala” or “āpaḥ”, in Sanskrit) are composed of moderately-dense molecules conforming to the shape of its environment or container (and in nature, often including at least some water molecules). GASES (AKA air - “vāyuḥ” or “marut”, in Sanskrit) consist of rarefied molecular particles of no fixed shape. HEAT (AKA fire - “analaḥ” or “tejas”, in Sanskrit) is made of kinetic energy (which may appear visibly as fire, or at least heat waves). ETHER (AKA space - “ākāśa” or “khaṃ”, in Sanskrit) is a vacuum consisting of three-dimensional space (length, breadth, and width). However, recent investigation has confirmed that empty space is actually filled with virtual particles (matter and antimatter). Thus, the explanation for the material universe being created from “nothing” (anti-matter) is plausible, according to quantum field theory. MIND (“manaḥ”, in Sanskrit) is composed of sensual perceptions, instinctual thoughts, abstract images (including memories and fantasies), and emotions. Not all animal species have a mind, but function purely on base nervous reflexes, generated from their specific genetic code. INTELLECT (“buddhiḥ”, in Sanskrit) consists of conceptual thoughts. Only the very higher species of animal life possess an intellectual capacity. PSEUDO-EGO (“ahaṃkāraḥ”, in Sanskrit) is comprised of the “I” thought (specifically, the illusory, ephemeral self-identity). Only humans possess the self-awareness necessary to question their own existence. Read Chapter 10 for a full disquisition of egoity. Each of the FIVE perceptible material elements corresponds to one of the senses of the body. E.g. In outer space, where there is a vacuum (ether), one can detect light with the eyes, yet space is not tactile and cannot be smelled or tasted, nor can sound waves travel via space. At the opposite extreme, solid matter can be seen with the eyes, felt with the sense of touch, tasted with the tongue, smelt with the nose, and heard with the ear (when the solid matter is physically vibrated). Beyond these eight material elements is the TRUE self - which pervades the entire body, and indeed, which encompasses the entirety of existence as the Universal Self (“ayam ātmā brahma”, in Sanskrit). Ultimately speaking, the authentic self/Self (“ātmana/Paramātmana”, in Sanskrit) alone is. The following chapter deals more fully with the concept of Infinite Awareness (“brahman” or “puruṣa”, in Sanskrit). However, all eight elemental groups are, in fact, “made of”, or an APPEARANCE in, Consciousness, since, as demonstrated previously, naught but Consciousness “exists”. Consciousness is the ultimate reality (“prajñāna brahma”, in Sanskrit). Just as a wedding ring is contingent on gold for its very existence, so too does the phenomenal universe depend entirely on Beingness (or “Isness”), Consciousness, and Blissful Quietude. Although The Absolute cannot be verbally-described, (otherwise, “it” would be an OBJECT), as a concession to materialists (who often demand concrete answers from religionists), Infinite Awareness is said to exhibit three innate attributes, known as “sacchidānanda”, a compounded Sanskrit epithet, consisting of the three words “sat”, “cit” and “ānanda” - Eternal Being(ness), Existence, or Truth; Pure Consciousness, or Perfect Knowledge; and Unalloyed Peace (often translated as “bliss”. However, the term “bliss” connotes an ephemeral experience of euphoria, whereas “peace” is a steady-state, absent of any form of temporal perturbation). Because Absolutely Nothing (“brahman” or “puruṣa”, in Sanskrit) is Infinite Creative Potentiality, “it” actualizes as Absolutely Everything. Attributeless Consciousness at Rest (in Sanskrit, “Nirguna Brahman”) manifests as this phenomenal universe (Consciousness in Action, or, in Sanskrit, “Saguna Brahman”). In the verbiage of quantum physics, the enfolded implicate order appears as the unfolded explicate order. In REALITY there is no separation of anything at any time (assuming that Consciousness is a “thing”, and that time is a property of The Uncaused Absolute). That the total sum energy of the universe is zero, implies the non-existence of matter (i.e. no thing is objectively real). Cont...

"remember the past, live in the present and dream of the future" is one of my mantras. I think that time is mostly subjective and an abstract meta catogary which helps us put what happens into order. From a physics perspective it seems more to describe space and interaction with it than having time as its own thing. We use time to describe other things, not the other way around. Even when you go into poetry and try to give time adjectives the mind mostly wonders to places than having it associated with time itself. Time is a tool to us. Perhaps that is why i find the french film Immortals so fascinating.

Thank goodness that WSF makes these panel discussion available soon after they have premiered them. Of what I did catch at the the tail end of this discussion and which made me scrunch my forehead is when one panelist mentioned that the idea of time travel is not present in older writings nor fables. That it is a concept that is relatively new. That it emerged in the last hundred or so years in fantasy and sci-fi writings. A part of me wonders if that claim is true. To me, it seems absurd that there are no spoken word stories nor poems nor plays nor any of the numerous myth-based allegories which religions are rife with which in some shape or form play with the construct of time. My curiosity has been set on fire. 🔥

If time is "something" then, what are its components? What is its form and in what ways is its presence manifested? We say that time can be measured but, what we actually measure ? I think that time has no components to work with them. So, what we have done and are doing is to measure the repetition of a phenomenon we arbitrarily define.
