The True Nature of Time: A Unified Narrative Understanding the nature of time requires an exploration of both its physical and experiential dimensions. This unified narrative synthesises perspectives from general relativity, field dynamics, and human consciousness to provide a comprehensive view of time. This synthesis highlights the interplay between spacetime curvature, informational flow, and the dual nature of temporal experience, ultimately framing time as a dynamic, integrative process. The Physical Nature of Spacetime 1. Spacetime Curvature and General Relativity - Einstein's General Relativity: Traditionally, gravity is not seen as a force but as the curvature of spacetime caused by mass and energy. Massive objects like stars and planets warp the fabric of spacetime, creating paths that other objects follow. This curvature is described mathematically by the Einstein field equations, linking spacetime geometry to the distribution of mass and energy. 2. Field Dynamics Perspective - Informational Flow: From a field dynamics standpoint, spacetime curvature results from complex field interactions. Mass and energy create disturbances in the spacetime field, similar to ripples in a pond. These disturbances represent informational changes that propagate through the field, maintaining coherence and stability. 3. Integrating Curvature and Field Dynamics - Unified Perspective: The physical curvature described by general relativity can be seen as a macroscopic manifestation of these field dynamics. Curvature represents the geometric interpretation, while field dynamics emphasise the flow of information and energy. This unified view helps reconcile the mathematical elegance of general relativity with a more intuitive understanding of dynamic systems. The Experiential Nature of Time 1. Linear and Non-Linear Time - Linear Time: In the external world, time is experienced as a linear sequence of events-a traditional, chronological progression. - Non-Linear Time: Within human consciousness, time is experienced non-linearly. This nonlinearity arises from the aggregation of sensory inputs, memories, and anticipations, creating a rich, complex temporal narrative that defines personal experience. 2. Boundary Layer and Human Consciousness - Constant Interface: The boundary layer between the external and internal worlds captures and integrates interactions and informational changes within the field. Despite internal non-linearity, this layer ensures temporal consistency, allowing the self to evolve coherently within the broader linear progression of external events. - Dual Temporal Experience: Positioned at this boundary, human consciousness experiences both linear and non-linear time. Externally, we perceive a continuous flow of time, while internally, our sense of time is shaped by the aggregation of various events and experiences. Dynamic Stability and Homeostasis 1. The Conscious Spiral of Dynamic Stability - From Circle to Spiral: In two dimensions, a circle represents static balance. When traced dynamically, it evolves into a spiral, representing dynamic stability. This concept extends to three dimensions where the human body is viewed as an electromagnetic sphere. - Human Electromagnetic Sphere: The heart generates electromagnetic fields, creating a dynamic sphere where information flows in a spiral pattern. This flow reflects how the body’s electromagnetic field interacts with and adapts to stimuli, maintaining homeostasis through continuous feedback mechanisms. 2. Homeostasis in Three Dimensions - Dynamic Integration: Homeostasis in the electromagnetic sphere is maintained through the integration of informational changes and feedback mechanisms. The boundary layer of the sphere captures the system’s current state, facilitating balanced feedback to ensure stability and adaptability. - Applications: This model applies to biological systems, where cells and organisms dynamically maintain balance through metabolic and signal transduction processes, and to larger systems like ecosystems and planetary environments. Conclusion The nature of time encompasses both its physical manifestations and its experiential dynamics. By integrating perspectives from general relativity, field dynamics, and human consciousness, we understand time as a dual phenomenon: a linear progression in the external world and a non-linear experience within the field of dynamic stability. This comprehensive framework reveals the intricate balance and adaptability inherent in the universe, enhancing our appreciation of the dynamic processes that govern both physical and conscious realms.

What she's describing as 'big' in time are systems with the most interconnections both in her mind and in reality. If you think of time as being either linear or cyclical, cyclical things remain the same 'size' in time, linear things continue to grow in complexity (specifically the number of agency/agent-directed interconnections). Everything contains a bit of both, but life hijacks the linear component of time in order to persist. 'Big in time' means intelligent things can make more choices. Across all of life, that sum total of all those choices creates a 'fanning out' in time that non-living matter doesn't. In a sense, the gestalt of life explores time for ways to persist. You have to really zoom out from the individual point of view to start seeing these patterns. I get what she's saying, but she's definitely coming from a non-standard thought origin and she's still working on the exact words to communicate it.

I don’t think it’s about the choice in regards to be “big in time”. I think she means literally. Take the 2D world of flatland with time as height dimension. A circular moving object will be a worm across the time dimension for us - a higher dimension being (4d beings, able to perceive 3D) Similarly a 5d being who can perceive 4d will see us humans to be a loooooong structure across the time dimension starting from the Big Bang! Additionally the space is expanding too, and we have interacted with huge distances using telescopes, light, technology, have converted so much energy - so we are ever increasing creatures.

At <a href="#" class="seekto" data-time="844">14:04</a> the answer is simple - as to “how humans can create so much order” which seemingly goes against second law of thermodynamics? It requires MORE entropy to create order. For example, we build a house - but the materials came from destruction of forests, extraction of resources, huge expenditure of fossil fuels to transport goods, a huge lifetime caloric requirement of a human - the order created from building structures is so minute compared to the enormous entropy involved in fuelling the creation of those structures. The same with our bodies and minds, they’re incredibly calorifically demanding, so any order we create is massively offset by the disorder needed to fuel it.

Time, as I understand it is the dual aspect of wave propagation and field dynamics. Originating from the Big Bang, time reflects both the linear sequence of events dictated by the metric expansion of space (as described by the FLRW model and Hubble's Law) and the nonlinear accumulation of coherent information influenced by quantum field interactions and informational density. The constant processing speed of the universe corresponds to the regular progression of cosmic expansion, while the nonlinear growth in informational complexity is rooted in the volumetric expansion and the dynamics of entropy and structure formation. Human perception of time operates at the universe's processing speed and is therefore linear, while our physical bodies respond to the cumulative effects of processed information since the Big Bang, highlighting the duality in our experience of and measurement of time.

Time is distinctly right handed: always on the right of the equation as a product. This is because time is a measurement that can be used only after the first three dimensions appear. There must be present first: space, then energy, then matter(energy that is static); then time can be calculated; but only as the formalization of observed matter(3-dimensional) moving through a vectored space.
@paulmichaelfreedman8334

Close, but the consensus is more that time is needed for change to occur. For change to occur, at least two particles of matter must exist that interact with each other. This interaction (change) creates time. Circle is complete. Many interactions in succession = time rolling forward as we know it.

I love this topic here, language vs thought meta analysis, humans have this unique ability to create highly abstract models in their minds so much so that even our language can't completely describe some of the most abstract/high level. That's always been interesting to me personally and a challenge I take on frequently, one of my favorite ones which is trying to compress such thoughts into plain language, like mapping a 1000 dimensional thought into a lower subspace, or to put it simply, ha, how to speak clearly and plainly about complex thoughts. If you can do that, perform that mapping eloquently, you’ll be successful because it is so valuable and people love that. It would be wild to imagine a world where it is normal to converse thought-to-thought, so much information could be shared, alarming scenarios aside.

This is not physics, it's just philosophy. Doesn't really matter if we are big in time or not. Universe is deterministic on the small scale but random on the grand scale. Good example is the weather. Also, it's not like people don't know we need to look deeper. People have not stopped and said "yep, that's it, we've figured it out", they constantly are trying to see the more detailed resolution of the universe

Couldn’t agree more. Its philosophy disguised as physics. This is apparent to any person of science & critical thinking. The language she is using will appeal to non-science types, people who are looking for complex descriptions to validate ideas without empirical data. Philosophy is certainly interesting and has its value, but I feel she thinks she's treading in the realms of physics - but she's not.

You’d be right if assembly theory wasn’t written down. You’re conflating theories and philosophy anyway. She’s saying things that are measurable, descriptive, and predictable. These are ideas in their infancy that don’t have established language and ways to talk about it. You could consider it closer to network systems or information science if it makes you more comfortable. It’s definitely not philosophy or metaphysics as I think you’re implying.

Sara is a new physicist to me and an exciting one. Is it necessary to the study of physics to spend so much time on the origin of life, although I can see it as a fun pastime? I think the very fact that she loves what she does, that it makes her smile, proves that we humans are special and stand out from other forms of life. I hope that she doesn't believe that a good future for humans would be to incorporate technology, which as she says is always ahead of our understanding of it, into our biology. She is living proof of why this would be a disastrous idea. Our brains are so much more than I think we can know at this time - the fact that there are people who have approached genius level with less than 80% of the brain most are born with tells me that there is something fundamental that is missing in our understanding of the brain's function.

Do that to the end of time and analyze the structure in its totality. Now, imagine doing this for the entire universe from start to end, and you will end up with a structure. I want to know of these structures. Even something as small as an electron will have a wildly interesting and complex structure in totality.

@@humanbean3 Well, it would be a planck length. so far, thats the smallest increment that we have aside from quantum stuff. The planck time is the amount of time it takes light to travel one planck length. According to our most current theories, nothing can be smaller than a planck length and nothing can travel a shorter distance than a planck length So, for each planck length, map the points of matter. Continue until the end of "time" then you have a total structure. Now, one common misconception i should say is that the "planck length" is the point where quantum gravity overtakes nonrelativistic gravity. Lastly, a philosopher named Democitus came up with the idea of the atom around 400 bc when he posed a thought experiment just like yours. He wondered how much can you divide matter into before youre left with the smallest piece. He called that thing "Atomos" meaning indivisible. Our current models go beyond the previous "indivisible". The planck length is our current "indivisible" It would be a bit foolish to think we wont get to a new "indivisible" in the future.

Think of a planck length as the smallest possible space for an observation to take place, any smaller and it would collapse into a black hole and evaporate before the observation would be complete. An observation often includes hitting what you want to observe with packets of light. the light then bounces back to the observation device. It's impossible for us to create light with a short enough wavelength to interact with something smaller than a planck length. There are smaller lengths in theory but they can never be observed directly. And are considered non-physical. I dont think the planck length can be regarded as a "pixel" But I do like using this length in my ideas as it is the smallest we can physically observe.

@@STaSHZILLA420 its really hard to fathom speed, size, and time having a limit. if we take the smallest particle like a nuetrino or something (idk) and make it move super fast, it will just disappear outside of time? that makes me think that the universe is spinning super fast like a harddrive and the slower we go the closer to the middle we are, and the faster we go the further to the outside we get, and if we go too fast we go faster than it can create/spin itself therefore disappearing???? is that what a black hole is? the star spins too fast for time to handle? ok sorry im rambling but i really appreciate the insightful comments

A note on the "alignment problem and its similarity to insanity": Dopamine is released in response to salient events... events that "standout and surprise the mind". A part of insanity is an excess of salience/dopamine in the perceived environment. In other words the experiencer is having a moment of incongruency between what is expected from the observer and what is actually observed. One way to remediate this is through dopamine suppression via medication...which can also depress movement and speech...feeling like chemical neural castration. And/or the experiencer can alter their expectations to more match the perceived environment or "reality". I think the issue I am having is I am too attached to my idealized mental model to want to adjust my perception to fit "reality". I don't frankly like a lot of what I see in "reality " and it chronically surprises me. In other words, I am so attached to my ideal mindset that I am willing to forgo sanity in order to fight for it. Anger arrives out of friction...friction between the observed and perceived models differing and "fighting for dominance". There's two ways anger can stop... through relationship building and reconciling the differences in perceived expectation between parties or anger can be reconciled through "caring" dissapearing. The latter is a very sad alternative. It's a type of mental dissociation that I think has been written into our DNA from many past traumas. We live in a culture that venerates this type of mental dissociation in order to deal with the differing incongruency between our childish expectations and the perceived world. It's easier to adjust one perception than it is to change the whole world. I get that. That's where this weird social psychology of "mindset" comes in. I think probably, the answer is a combination...as usual. I obviously air on the side of idealism. It's a very vulnerable and somewhat mentally disabling place to be. I also believe our obsession with science and fact finding is a type of mental dissociation that numbs the pain of the world. The number of engineers and scientists we have far outweighs the number of humanitarians we have. It's HARDER to be a humanitarian. It's a weird age we live in and frankly, from an emotional intelligence perspective, not a lot of it makes sense to me but hey. I'm here. #staying sane since circa 2023.

If information cannot be destroyed, then the whole universe could be the computing or technological potential but if time exists then it’s not just potential. Time might be the storage media for all information that could be retrieved by a consciousness capable of perceiving it. Perhaps this is why time feels intangible, almost illusory yet the past and future are almost within grasp…a memory, a dream, a hope, a will…..the dimensional trap of human suffering.

Easiest way I imagine it is….time is how long it takes your elementary partials to get from point A to point B. Mass bends space like putting something heavy on bedsheets, and it obviously takes longer to get from point A to point B if your journey isn’t a straight line. The more mass, the more space is bent, the longer it takes to travel from point A to point B therefore time is slower.

One can argue the history of science is kinda like the history of thinking something is "random" (in the sense that we can not know) to just then figure it out and reallise that wasn't random at all. Wheter quantum phenomena is truly inherently random or not is stil not concusively decided. It very much seems it is for now, but again, a heart attack in the bronze age seemed so random and unexplainabe that it was might as we taken as divine punishment.

if universe is fundamentally random, it means existence of life is inevitable.. Life is just enough complex system capable of intwntionally avoid increasing of own entropy by harvestig energy from it’s enviroment) Now, in random universe, random events are stacking on eachnother.. sometimes it leads to system which can resist entropy increase for some short period but then entropy wins and that sysrem ceases to exist .. But if you give it enough time, enough random events stacks together so they lead to more complex sysrem, which is capable to evolve to even more comples system (with still contributing random events).. give iz enough time (billions of years) and space and life just emerges.. So what is live - just enough complex system which intentionally uses energy of it’s enviroment to avoid incrrase of iťs own entropy. And it is resultnof fundamental randomness of universe.

3-dimensional objects, whatever they consist of, define time integrally as the observed description of matters' self. So, first is the real matter, not defined in anyways, then comes the formalized description of that matter; using time as the measurement of the dimensional attributes of any matter. Time arises from the second dimension, incomplete until it is tied to at least 2 points of finite nature. One point in a vectored space cannot cause time to arise. Possibly singularities eject time, and therefore 2 dimensions, as compression occurs: after being unbound by a singularity, time simply ceases to exist locally, and becomes space itself; without being bounded by mass(Higgs Boson) or baryonic matter of any kind, and falls into a state of plausibility: waiting on space and mass to combine; which then requires those all important 3 dimensions that produce distinct dimensions. Time might be an inferred or emergent property of the combination of mass, space, and the invasion of gravity--the combination of the Higgs particle and the electromagnetic force--even to the point of being the weak force of electromagnetism (possibly), forces one dimensionality to double in a linear manner, this forces the time(an essential part of length, with and depth) measurement to occur. Time arises as the second half of the first three dimensions: it can't possibly exist on its own. This causes time to be contained to matter: making time to be expressed as a product; thus always forced to be on the right hand of any equation if solved properly.
