  • What does it mean for space and time to be the same thing? Not related to each other, but literally two descriptions of precisely the same entity: "spacetime"? One cannot understand existence without understanding spacetime.

      Space is the ambient within where the whole universe exists. Space in and of itself can exist as being totally empty of any matter or material thing and still be as vast or perhaps infinite as the existing universe. Time however does not exist in empty space even as time does not exist in and of itself. Time is but a measure relative to the actions and interaction of all the matter in the universe.. so in a sense time is a measuring device and is unlike the reality of space.

      Where he is sort of correct is around 4 minutes, in that we can only define any motion or existence of something measureable by subjective reference points. However I really don't see how that should advance a classical general relativity or "linear tidal mysterious space" over special relativity. And I don't see how the possible inherent flux of space should make a study of particle dynamics and respective force fields less important.

Conversation like this, even if they have more than 400 years of philosophy, (because let's get grounded here, it's all mental-matters, not our actual experience), it all sounds like a black hole for our common sense, interpreted as "profound deep inquiry".

    Nice talk :) Although not a physicist in recent decades I have come to think of space and progression/time as the being the polar opposite of one and the same thing. A bit like the concept of photon polar orientation or quantum states. Space and time can flip states under certain conditions where time becomes space and space becomes time such as the even horizon of a black hole.
    But then I do sometime feel to subscribe to my thinking that everything we perceive is nothing more than an elaborate holographic universe stored on a massive advanced static computer like data system.

    isn't it just a specific container that holds a linear sequence of atoms and the length of atoms in sequence from point A to point B determine the space and the time simultaneously since we measure time through materiality and all material things are made from atoms?

    Seems to me if you the flow of causality events at a quantum level as being the definition of time it seems emergent. It is like the definition ticking of a clock. We think of it as a measurement of time but from the opposite perspective it is a series of mechanical events that are occurring based on physical causation that was designed to repeat and we use this emergent property to represent time as it can be related to the sequence of other events. Since events happen in a causal sequence then time emerges.

  • @danimalplanet18
    @danimalplanet18 Před rokem +2

    If we describe an event we always need to determine the 'when' and the 'where' - if we meet up at the same time but in different places we don't get to experience the same event. And the same applies if we're at the same location, but at different times. From our human point of view, the two must be connected.
    But does that mean that we experience things the correct way, or are we missing something; much like ants whom see the world in 2D?

    Really interesting down to earth person that I could listen to all day. I've been thinking the same thing but I definitely lean towards time being an emergent property of more fundamental things interacting, such that it does not exist. The same thing goes for space. Space is "is" that thing interacting i.e. space is just energy fields and configurations providing certain interactions and dynamics. This is of course very complicated as energy exists in many different ways: fundamental forces, solid masses, vacuum with particles blinking in and out of existence and certain quantum environments (think about cmb, dark matter, vacum decay etc). From that perspective I'd like to visualize it such that space, or energy, flows through objects. In certain cases it's very obvious, like with the fundamental forces. In other cases it's only noticeable when you travel at large speeds or hang out with massive objects. This flow slows internal speed, but not external speed. Which then is a way to view time dilation. Of course, these are all very complicated relationships (hyperbolic for instance) but at its core, at the end of the day, it's "just" a swim through a surprisingly complex but structured soup.

      @@josephfreetimer1736 it’s not the most straightforward concept to explain, but I’ll do my best:
      Imagine a graph, or perhaps better, a map, drawn on a grid fixed so that every location (point on the graph) has a location defined in reference to coordinates on that grid. Now, imagine lengthening all the edges of the grid’s squares, so that the graph/map/whatever you’re imagining drawn on it stretches along every axis. That’s what expansion of space in the universe is like, except that the matter within the space (everything physical) is ‘confined’ by the attractive forces (electromagnetic, gravitational, strong, weak) it feels and imposes on all the rest of the matter local to it - such as, for example, the attractive force the sun and the earth have on each other as they orbit - keeps the material within the universe “locked” into relative positions with respect to other matter, so that although the fabric of space within which it is contextualised expands, the matter experiences only the slightest of affects, which are dwarfed by the much stronger affects of the forces, due to fields such as the gravitational field which drives change in their relative positions.
      This is general. Actually you are (at all times) being pulled outwards in all directions simultaneously by the expansion of space, however the attractive forces (predominantly electromagnetic and strong) between your constituent atoms, and the subatomic particles within them keeps you whole. Without these, you would spread out into a diffuse cloud (albeit imperceptibly slowly) as the universe you are imbedded within gradually expands. Note that this gradual expansion is radically slower and less impactful than the rapid expansion the universe likely underwent in its inflationary phase (according to our most likely theories).

    The Block Universe becomes much more attractive if we consider time to be a 4th spatial dimension. But, as is so clearly pointed out, we don't understand the most fundamental characteristics of our universe. And because we don't, every avenue of exploration is based on some fundamental assumptions that may or may not be correct. What the heck is a dimension aside from its simple mathematical construct? Are there 3 or 4 or 10 or 11 or an infinite number of dimensions? Are they causal (emergent) or infinite and in place forever before and after? What is space and time? Is space and/or time discrete (quantized) or continuous? Can time, in any instance, run opposite to what we experience? Doesn't the idea that a particle can be in more than 1 place at any given time negate the idea of causality? Or is causality the absolute bedrock of reality? Are space and time fields and if so, are they static or dynamic? We can't even agree as to what Nothing is. There are so many unknowns at the fundamental level that any extended model of the universe such as the so-called Standard Model with Inflation is built on unproven assumptions, beliefs, and biases. It may be a house of cards, but most will stick to it despite it's shortcomings. But we need to be aware that it is philosophy (little "p" philosophy as in beliefs and assumptions, not big "P" Philosophy as in Jeremy Bentham or David Hume or Socrates) at the heart of our description of the Universe. We need to keep reflecting on the fundamentals to be assured that we are on the right track and keep investigating those base ideas which are unspoken but extant in our models and shape our investigations.

    Try thinking about time as a measurement of things that have a physical presence and affect other things.
    Events always include (almost by definition) movement, the movement, from one place to another of something tangible, such as matter or radiation.
    Time measures the changing movement of objects but has no power, energy, or effect on anything.
    An accurate analogy is Temperature, which doesn't make a thing hotter or colder, it only measures one particular state of an object. Time is no more a "thing in itself" than is length. Both are measurements. If nothing moved there would be no time.

      Yes actually you are correct. As a child I looked at a clock and wondered if I could stop time, or by concentrating on the second hand, slow it down. Obviously one cannot, becauuse it is the movement of the hand from one point to another that we take to represent time. That is how space and time are related. But to go further, don’’t think in terms of material things - ultimately there are only patterns of energy. The clock is a mechanical pattern, the solar system is a gravitational pattern, and so on. Ultimately all “material” objects are just patterns of energy (as far as physicists can determine at this “time”). Then Smollin’s point of view makes sense, that causality is just patterns of energy interacting. Whether one billiard ball striking another, or running into a friend and talking about the football game - in which case the patterns are the stored memories in your brain interacting.

      An intuitive approach would be to think about walking. I walk from my bed to the door. These are two distinct points in space and time, i.e. where I am is a distance away from where I'll be, and when I am is a distance away from when I'll be. Now add in a magical observer a light year away, who watches me walk to the door by analyzing the light that bounced off me. It takes a year for the light to get to the observer, adding another distance in both space and time. Relative to the observer, that event (which caused the information on the light that informed the observer to exist) is happening right now (since they are seeing it right now). Relative to me, it happened a year ago, likely in a very different place from where I am then. What relativity says is that both people (or frames of reference) are correct; time and space are relative to the observer. Now what can we say about the relations of these two people? If I wanted to tell the observer something, causing a thought process in them, light would have to travel to them. The relative amount of time it would take IS the amount of space between us, and so the two are isomorphic (can be mapped onto one another 1 to 1).
      This is how space and time are combined into spacetime, and their relation is entirely constituted by causality, specifically its sequencing (how long it takes for information to travel). Hope that helps a little.

No experiment has shown that time passes more slowly while traveling faster or further away from a large source of gravity. All we have as a proof of time dilation is the the atomic clock. While the time difference that occurs in earth based clocks vs space station clocks appear to prove time dilation, that is a mistake. It could be a property of the cecium atom. It could be some other phenomenon yet to be explained. It is circular reasoning to use the math, thought experiments based on the math, and a single observable fact to confirm that which is known to be in error.

      Gravity is the Singularity.
      Spacetime is the Singularity.
      It is all tied together: wave-particle duality, the thermodynamic arrow of time, redshift, blueshift, dark energy, dark matter, and black holes, are actually all manifestations of relative infinity.
      Gravity can be described as the path of matter through spacetime relative to the speed of light in relation to the Singularity (i.e. the speed of light in a vacuum. The Singularity is infinitely dense and infinitely vast, encompassing all observable spacetime and beyond). All matter in an infinite universe warps spacetime and concurrently alters the path of all other things. Since on a fundamental level all matter and energy resides within the Singularity, all matter and energy is its own cause and effect as well as the cause and effect of everything else. E=MC^2. Matter and energy can't be created or destroyed because they are fundamentally infinite. Observational physics is relative. Infinite physics is fundamental.
      If you can't think on scales of infinity you will literally never understand.
      An apple in your hand warps spacetime as demonstrated by Einstein, but what scientists can't seem to wrap their brain around, is that any object that warps spacetime alters the path of every other object in an infinite universe, instantly. Everything is connected.
      You all want an explanation of how GR and quantum mechanics are compatible, you got it. The Singularity is the unifying factor.
      Wave particle duality is a reflection of the effect of observation on the particle level. Perpetual observation of the interactions of light with our environment persistently impacts the trajectory of all particles and sets the parameters of relativistic physics.
      Quantum entanglement is a reflection of the interconnected nature of reality.
      The reason one particle can persistently affect another across indefinite distances, is because of the fundamental nature of gravity.
      All cause exists relative to infinite effect.
      All effect exists relative to infinite cause.
      Observational reality is always infinitely far away from a "singular point" of infinitely high energy/information density (the relative past), and infinitely far away from a "singular point" of infinitely low energy/information density (the relative future).
      This is what establishes a frame of reference for relative observation. You can never reach either "point" through the passage of time relative to observation. No matter WHAT you do, each is infinitely far away.
      Light is essentially stretched from infinitely high energy to infinitely low energy. This is why light redshifts in accordance with the thermodynamic arrow of time. In other words, Dark Energy is the tension between the "point" of infinitely high energy density and the "point" of infinitely low energy density.
      If you were to approach a black hole, you would never reach the event horizon from your relative perspective. The event horizon would recede into the distance relative to your position and motion through spacetime. From the perspective of an Earth observer, you would freeze at the event horizon, which is the Earth observer's relative moment in time. From your perspective, you would proceed into the relative future.
      Nothing is truly improbable or probable, and every relative calculation is always infinitely inaccurate.
      Every proof ever written, every word ever spoken, is infinitely inaccurate due to the relative nature of math and language as tools for conceptualization, computation, and communication of information.
      We know the Universe is infinite because our language and mathematical symbols are arbitrary and relative to our experience. I can make a 2 character language such as binary code, a 37 character language, or a 998,000 character language... All the way on to infinity. This is because all language exists as a tool for describing relative infinity.
      I can use our standard, base ten mathematics... Or I can create base 100 mathematics, or base trillion mathematics, using completely unique symbols that I can make up, all the way to infinity.
      This is because all math exists to describe relative infinity.
      The Mandatory Asymmetry Principle:
      Before we get to the Mandatory Asymmetry Principle, let's start with the Infinite Precision Principle.
      Both can be explained quite simply, using the basic geometric analogy of a square.
      The Infinite Precision Principle dictates this: take a square. You measure it with a ruler, you get exactly one inch per side. Great.
      Moving on, right?
      Not so fast.
      You decide to amp it up a bit and measure that square to the nearest 10,000th of an inch. You measure again, and this time you get 1.0001 inches. Your initial measurement appeared accurate, but a higher degree of precision found this to be untrue.
      The Infinite Precision Principle states this: no matter how accurate you think your measurement of the dimensions of an object are, there is always infinite room to improve upon your measurement. No matter how many times or to what degree of precision you magnify your measurements, a higher degree of precision will eventually prove your initial measurement inaccurate.
      The Mandatory Asymmetry Principle, when understood as it proceeds from the initially described principle, is as follows: take two sides of the square from the previous example. Let's say each side measured in initially at exactly 1 inch, then 1.0001 inches with the higher precision measurement.
      You amp it up again- this time the nearest billionth of an inch.
      This time, the measurements are as follows: A) 1.000100002 inches, B)1.000100003 inches.
      So at a higher level of precision, you realize you never had a perfect square to begin with, at all.
      The Mandatory Asymmetry Principle states this: if any given measurement of the dimensions of an object relative to observation, appears to be symmetrical, a higher degree of precision will eventually prove it is not.
      Key insight: there is no such thing as a perfect square, or a perfect hexagon, a perfect pyramid or a perfect sphere.
      Implications: every single object existing in our Infinite Universe is unique, and nothing can be measured perfectly in relative terms, ever, by anyone.
      For every object in the universe to be unique, the universe must be infinite.
      You can't measure the speed of light any more than you can measure the sides of a square. Because the only thing that is real, is infinity.
      Imagine the entire observable Universe is a basket with 2 apples and 4 oranges. We live in an orange, and we can't see what lies beyond the basket.
      Now, imagine the entire Universe is an infinite number of baskets, each with 2 apples and 4 oranges.
      There are infinite baskets, infinite apples, and infinite oranges.
      Basic logic dictates there are half as many baskets as apples, and twice as many oranges as apples.
      The basket is like our observational bubble. Every phenomenon we observe happens inside the basket. The ratio of apples to oranges is like our physics. We can define the physics within our basket in relative terms and convince ourselves the description is accurate.
      Or, we can define the physics of the infinite Universe in terms of the frequency of apples and oranges relative to infinity.

    It is one thing to postulate about time and space being co related or even being one thing. From the scientific and the philosophical perspective we can conceptualise the possibility of being so. However as beings that are captured in matter, relative to space and time, our experience is somewhat different to what the Physics and the Philosophy might suggest.
    And the interesting point is exactly that even those who are elaborating from the standpoint of science or philosophy about time and space, are never the less captured , just like anyone else in our human experience of time and space.....
    In my opinion this fact tells us more about our mental capacities of conceptualisation, which goes beyond our experience, than what it actually tells about the relationship of time and space.......

    I found the easiest way to understand this, the nature of space, is to think of it like your computer screen, made up of pixels in array. These pixels are refreshed at a specific rate - 60 times per second. Assuming in this case that pixels can transmit causality to their neighbors, That means action can only move across the screen 60 pixels/sec no more no less. That is your “speed of light”
    Now consider a circle made up of pixels with many colors. If that circle where to move across the screen slowly, it could still change color, but if it moved left across the screen at a rate of 60 pixels/sec, Every action would have to be dedicated to translation to the left, and would not have the opportunity to use an action to change color. Its color pattern is fixed, it is no longer moving forward in time. All of its updates are dedicated to translational motion. If that were a person moving at the speed of light, they would appear to be frozen in position to an outside observer, not a heartbeat, not a molecule moving in their body, except in one direction at the speed of light. To the outside observer, time for that person has stopped.
    Now back to the circle: slow down a little bit from the screen version of the speed of light, say down to 58 pixels/sec. The circle can now use two pixels per second to change its color state, but that would be very slow compared to the circle that is standing still. Time for the "sub-lightspeed" circle is moving very slowly, but it has not stopped
    This is what is meant by space and time being intimately connected. In fact, there is no time without space, as time is simply the updating of the components of space (the quantum fields)
    Now in quantum physics, there is the concept of the Planck length, which may very well be the absolute minimum "pixel" resolution of space and the units which are transmitting causality

  • @civilizedvisualpresence7843

    Dear Dr. Kuhn. Thank you for such a great contribution. Dr. Smolin clearly explained theoretically the causal link between space and time in close relation to events in space and time, because time is not an illusion, particularly when it is applied the Physics, Chemistry, etc in scale. The science in scale together with the utilization of cosmological laws, it explains the differentiation of organizing systems in a certain space and a certain time in the causal link space-time. Doctor Smolin only is using as well known in the scientific circles an effort for experimental agreement of "one single worldedness", to pacify the scientists arguing for the one universe, and those scientists arguing for the multiverse. But "one single worldedness", Dr. Smolin knows as well it is the same attempt that Newton or Leibniz tried at their time in order for their scientific theory to win. Dr. Smolin has done a great job, but he should continue it further in theory with the help of practical experiments of different scales.

In that context, the scientific contribution of Newton is well accepted in our planet Earth, but also it is understood the restrictions of his scientific steps in his thinking that our planet Earth is the "lucky one", as Leibniz was stating in his "Philosophical Essays", that God created our planet Earth as the best world. So, my arguments in scientific view of such restrictions in scientific knowledge of Newton and Leibniz, were in the European religions endorsed, stating that "we are the center of the Universe". The idea that we are the center of the Universe is not true, and it is proved by the existence of other extraterrestrial civilizations, which for I do not need to go in further discussions.

      He’s describing a static universe where time is simply a perception as we move through space configurations, so at any given point there are potentially a variety of paths available to the next configuration. Causality requires a time dependent relationship where one event impacts the next but Barbour is getting at Hume’s observation that causation is simply an association of matters of fact which require an inference. In that way the events may be independent & just appear correlated by how we move through the configurations. It’s possible, but perhaps much less probable, to take a different path. Please interpret the words path, move, & take metaphorically.

    The intuition I follow is that both notions (space and time) relate to "distance" between things. Something that is farther away takes more time to reach. Something takes more time because it is farther away. Both measure how difficult it is (as in how much energy is required) to go from point A to B. It's a degree of separation.The Big Bang separated the singularity into infinity of pieces. But what does separation mean? It means adding space, or time, between the pieces. And we can observe both space and time keep going and expanding. The chain of causality they mention in the video is all these parts, energy, traveling through the spacetime.

      Critical editing was invented around 400BC at the Great Library at Alexandria.
      This was around the time of Socrates and the invention of Socratic Argumentation.
      Critical editing lies in looking at a work and rewording it to make it better express the meaning it is intended to deliver.
      I reviewed, edited and revised this before posting.
      Critical editing can replace whole paragraphs of vagary with one sentence of solid description or remove a nonsense sentence and replace it with an informative paragraph... it can even omit whole chapters.
      Socratic Argumentation involves honest evaluation of one's own argument and a willingness to compare it to their opponent's argument and to be willing to accept parts of the opponent's argument and to reject parts of one's own if those parts show to better or worse describe the idea being argued over.
      In a normal argument, one generally makes a bold statement and defends it to the end even if it is shown to be inherently false.
      Two hundred years later, also at Alexandria, the scientific method was invented and this was done using the same essential rules of Critical Editing and Socratic Argumentation but based on claims about facts, and so leading to the invention of expermentation.
      2,222 years later, give-or-take a week or a decade, Lee Smolin said:
      "What is good for scientists to do?

      "Because it is so easy to fool ourselves, we develop crafts.
      "Crafts of experiment, checking our experiments, checking our calculations over and over again to detect error.
      "And, indeed, the training of a scientist is primarily a training in the detection and elimination of errors.
      "It's not about ideas--lots of people have ideas and every once in a while there's a good idea--it's about showing that your ideas and other people's ideas are BAD ideas by finding errors.
      "And a scientist is somebody who has a degree that basically consists in demonstrating that they have control over... mastery over a craft for detecting errors."~LS

    My best understanding is that time, sequence, and causality are the same, while space is a passive stage. Each moment creates the next moment. We don't travel through time, we proceed from event to event, cause to effect, endlessly. So, yeah, tell me how I'm wrong.

    I hypothesize that there are two measurements of duration, universal and relative. Relative duration is measured with respect to the relative nature of the duration of the forming of structures. Where universal duration is a constant measurement of the present tense duration of the progression of the evolution of the universe.

Does that mean nothing is real? What about the neurons in our brain? Those are physical things that have volume. That is how we think and engage with the world. Is that not the seat of our own individual consciousness? Is anything real and do we cease to exist when a set of dynamics dictates our neurons no longer take up space?

      There is something rather than nothing because nothing can never exist . Nothing is the absolute opposite to something .

    It's interesting to note how our level of consciousness is seldom equated into these observations....that time could be a result of our limited consciousness. The brain's evolution may require sequences of events (causality) to create reality rather than being able to perceive our universe as a unified whole. It seems that consciousness as the observer must be factored in. Thanks to Lee and Closer To Truth.

Help my brain connect with my mind here: Where is all this "expanding space" expanding into? Anti-space? Conversation like this, even if they have more than 400 years of philosophy, (because let's get grounded here, it's all mental-matters, not our actual experience), it all sounds like a black hole for our common sense, interpreted as "profound deep inquiry".

It just appears the acedemics are trying to describe reality in mathematics and if it gives the expected results then given time passing, it must be true because the maths doesn't lie. (Does Dark Matter ring a bell here?) Yes, I know about Newtonian mechanics were superceeded by Einstein's Special and General theories we have today but this was all capable of being proven by scientific experiment.
