    Even if the universe is fundamentally non-deterministic, I still dont get how that would contradict the block universe. Just because it is a 'block' that could hypothetically be viewed as one by a higher dimensional observer, doesn't mean it has to be deterministic in any way. The question of determinacy just asks if those observers would be able to infer the 'future' part of that block from the 'past' part (if you cut it in half at our present).

    • @EugeneKhutoryansky
      @EugeneKhutoryansky  Před 9 měsíci +39

      A non-deterministic universe does not necessarily contradict a block Universe, and I stated this in the video. But, I then went on to present the detailed explanation of why we do not appear to live in a block universe, based on how the entanglement of quantum spin works.

      @@EugeneKhutoryansky The explanation you gave assumed that a hypothetical observer who could see the entire block universe would also be able to see the results of hypothetical measurements that weren't actually made. Most interpretations of quantum mechanics do conflict with that idea, but the block universe doesn't imply that an observer like that could ever exist.

      Block Universe is a totally useless concept if it fits anything, even non globally hyperbolic spacetimes ( as, for a typical example in semi-classical physics, a universe that has Black holes that are completely evaporated after a finite amount of time, without leaving any remnant behind), or non deterministic ( as in the standard QM).
      The notion of a block universe has a meaning only in spacetimes that are globally deterministic.

    • @dimitrispapadimitriou5622
      @dimitrispapadimitriou5622 Před 9 měsíci +2

      Even in deterministic versions/ interpretations of QM , like Many Worlds it is doubtful whether the block universe Idea has any useful meaning, even philosophically.
      We don't even know if any of these interpretations make sense in the ( unknown yet!) theory of Quantum Gravity ( or whatever else reconciles QM with GR).

  • @AhmedAzizou
    @AhmedAzizou Před 8 měsíci +2

    @EugeneKhutoryansky, perhaps the following line of reasoning can be pursued to prevent the block from shattering: If we do not disregard Quantum Mechanics in its current understanding, the block universe can be conceptualized as akin to a frozen snapshot, encapsulating a series of measurements of outcomes-or a single observation-across the temporal dimension. Consequently, this notion of a block universe necessitates that an external observer MUST exist for a particular outcome to materialize. This external observer, conducting alternative observations, could potentially bring an infinite array of possible universes into existence, each one forming its own block.

      Let's delve into how these concepts from special relativity can be applied and interpreted in the context of a 4D fractal landscape as opposed to a strict 4D block universe.
      1. Rindler Coordinates
      4D Fractal Landscape:
      In a 4D fractal landscape, Rindler coordinates can be used to describe the trajectories of objects in a non-inertial frame, allowing for a more intricate and detailed representation of the dynamics of objects within this fractal structure, which might involve complex, self-similar patterns at different scales.
      4D Block Universe:
      In a 4D block universe, Rindler coordinates would be used in a more straightforward manner to describe the worldlines of objects in spacetime, where all events are fixed and unchangeable, essentially providing a grid over the block universe to map out these worldlines.
      2. Bell Spaceship Paradox
      4D Fractal Landscape:
      In a 4D fractal landscape, the Bell spaceship paradox could potentially be visualized in a more complex manner, with the spaceships navigating through a landscape filled with intricate structures and patterns, potentially leading to more complex and rich dynamics and resolutions to the paradox.
      4D Block Universe:
      In a 4D block universe, the Bell spaceship paradox would be visualized as worldlines of the spaceships in the spacetime, with the resolution of the paradox coming from the realization of the different proper times experienced by the observers in the spaceships, a concept central to special relativity.
      3. Hyperbolic Spacetime
      4D Fractal Landscape:
      Hyperbolic spacetime can be seen as a geometric representation of the spacetime in a 4D fractal landscape, where the spacetime itself might have a hyperbolic geometry, leading to fascinating and potentially very complex dynamics, with a rich structure of geodesics representing the paths of objects.
      4D Block Universe:
      In a 4D block universe, hyperbolic spacetime would represent the geometry of spacetime itself, potentially leading to a different kind of block universe with different properties and structures of worldlines, providing a different perspective on the nature of spacetime.
      4. Mathematical Applications of Differential Equations in Special Relativity
      4D Fractal Landscape:
      In a 4D fractal landscape, differential equations would be used to describe the dynamics of objects within this landscape, potentially involving complex, fractal-like solutions representing the intricate dynamics of objects within this landscape.
      4D Block Universe:
      In a 4D block universe, differential equations would be used in a more straightforward manner to describe the worldlines of objects in spacetime, potentially involving solutions that represent the fixed, unchangeable trajectories of objects in this universe.
      Conclusion:
      In both the 4D fractal landscape and the 4D block universe, these concepts from special relativity would be central in describing the dynamics and structures present. However, in a 4D fractal landscape, these concepts might take on a more complex and rich character, involving intricate, self-similar patterns and dynamics, while in a 4D block universe, they would be used in a more straightforward manner to describe the fixed and unchangeable structure of the universe.

    Something I’ve noticed about quantum entanglement implying probability. “Observing” in quantum mechanics means a very specific thing: running a particle through a detector. But this requires energy to interact with the particle, which on such scales definitely affects the particles.
    So there is no mystical property to “observing” a quantum spin, it’s a matter of needing energy to measure the spin and adding energy in a way that detects spin changes spin to align a certain way. I.e. going through a detector polarizes the particle.
    If you detect a particle to have one spin, then run it through a perpendicular detector, does the particle change spin? If so, does its partner change spin? I know this doesn’t allow FTL because you’d need to compare notes later and all that.
    The act of observing indeed changes the outcome, but it seems to me like that outcome could have already been determined. Even assuming we could never improve detection technology to NOT polarize a particle, i.e. a 360 degree spin detector, that doesn’t mean a “true” value doesn’t exist. It just means we cannot measure it without messing with it.
    That’s fine in other sectors of science. We understand that a tree falling in the forest still makes a sound even if no one is around to hear it, and we understand that human behavior can affect if/when a tree falls, even indirectly.

It's impossible to make a measuring apparatus that won't bias the result in some way toward what you have designed.

    Another way to explain this is that a particle doesn't actually exist until a measurement is made. The measurement is an interaction, so we can restate the above as: a quantum iota behaves as a probability wave until it interacts, at which point it behaves like a particle. And also, particles themselves can never be entangled, rather it is that only one probability wave exists to conserve the properties of any two iota quantum system created by a single event.

    Do you mean you first measure particle 1 along the first axis and particle 2 along the axis with a 45 degrees offset from the first axis. Then the next measurements along any axis of the two particles will be opposite of each other 85% of the time? That is the colours represent another set of measurements?

    Just some random ideas while watching: Could the situation be compared to an irrational number? Irrational numbers don't follow a pattern but further digits can always be calculated. (Genuine question) Would you classify irrational numbers as deterministic? Each successive digit appear random but still can be calculated. Maybe the universe behaves like an irrational number? It is computationally irreducible but just like we can write root(2), it all exists. Time would then be the computation pushing it along. Maybe I'm off base just a random thought.

    • @StellaEFZ
      @StellaEFZ Před 9 měsíci

      I like your theory but I don't think the comparison holds, because, irrational numbers are infinite in lenght, so calculating all it's digits would require infinite energy; and in the same vein, calculating all future outcomes of the universe would also require infinite energy, which is impossible with our current understanding on physics.
      Irrational numbers can still be calculated in some fashion, on the same way we can predict physical systems if we have a set of starting conditions as we do with irrational numbers, but we can never be 100% sure and only approximate it in the end

      I think I agree with you essentially. I think the universe at its base has precision limits on information, or at least on the transfer/measurability of information, yet the universe allows interactions/relations that would require infinite precision to actually resolve. The “shape” of a timeline requires infinite time to resolve, like a circle shape requires infinite detail (infinite size if you think of the shape as expanding as you zoom in on its edge to take more precise measurements) to measure its side.

    This is a very well done video and at one level makes a very good point that, to the extent the universe is probabilistic, then this would seem to conflict with, in fact, dispense with Block Universe. However, let me challenge this conclusion: It seems to me that it is still possible that a Universe of FOUR dimensions could still be a Block Universe in the context of those 4 dimensions. It is the addition of probabilistic quantum behavior where we introduce the FIFTH spatial dimension. So, in 4 spatial dimensions you get a single block. But by adding the 5th spatial dimension where in to quantum randomness propagates, we get the Multiverse. Could not both be true?

    Please Help Me
    A moving rod placed in a stationary U-shaped frame.
    When a conductor (the moving rod in this case) moves perpendicular to a magnetic field, an electromotive force (EMF) is induced according to Faraday's law of electromagnetic induction. The rate of change of magnetic flux through the loop formed by the moving rod and the stationary U-shaped rods is given by = B⋅L⋅V where B is the magnetic field strength,L is the length of the rod, and v is its velocity.
    Now, the negative of rate of change of magnetic flux = work done by electromagnetic force throughout the loop, which is BLV+IR, i=current , r=resistance
    But this leads to that,BLV=BLV+I--->>IR=0 , means electric current through loop is 0, So, Just Please Clarify My Confusion

      The reference to an external observer is just a metaphor to describe the idea of a block universe. But, the idea of a block universe is contrary to the idea that the outcome of a measurement is intrinsically probabilistic, until the measurement is actually made. This is because in a block universe, everything is already determined ahead of time. Thanks.

    Fun fact: Let us hypothesize that our universe can be described in three spatial and two temporal dimensions such that the Euclidean, flat, spatial distance between two events (points in this 5-D system) equals the Euclidean, flat, temporal distance (time lapse). Formally:
    (δx)²+(δy)²+(δz)²=(δt)²+(δτ)²,
    where x, y, and z are a changing event's spatial coordinates and, t and τ, its two time coordinates, and δ is the change's differential operator.
    In such an hypothetical, flat 5-D universe, Leibnitz's invariant transformation
    (δτ)²=(δx)²+(δy)²+(δz)²-(δt)²
    holds, without having to resource to a hyperbolically curved 4-D timespace!
    If we define action S such that
    δS=(δx)²+(δy)²+(δz)²-(δt)²-(δτ)²
    then the above restriction (equivalent, as we saw, to Leibnitz's invariant transformation) is also equivalent to the principle of least action.
    So, should we rather consider our universe five-dimensional and flat, with a restriction (one less degree of freedom) like stated above?

    This seems to be true where the particle does not exist in any state until it is quantized, but the Copenhagen interpretation is that it exists in every state simultaneously before quantization. If we're talking about a state of the universe that is itself external to time--that time is a property of things in the universe, and not the universe itsef--then this is exactly what one would expect. If the inderminate state of the particles were not such that all possibilities are true at the same time--Schrodinger's cat being both alive and dead--then entangled particles would not be much use for quantum computers, would they?

    Eg: If the future state of a screwdriver ends up being a banana because of random possibilities; this obviously would not work. The future must influence the present conditions in order for them to find their way into itself.
    The Present is the Past of The Future; and the Future of the Past. Its all connected.

    all the inconsistent futures could be impossible for reasons we do not understand yet, and all the "overlapping" futures (for each time line) might turn out to just map to the same underlying block ... - but I guess this is just assuming non-locality. (which I do not find unlikely at all. In fact, I think the "3D" universe we are experiencing is a projection of some actual underlying structure, and that would allow non-locality (especially if path an observer takes is a homotopy of projections from their local time))
    - Anyway, this proof requires locality as assumption, if I understand everything correctly (not a physicist) and that is a big if.

    However, if we did live in a block universe then every measurement that has ever been made or ever will be made and the outcome of these measurements would already be determined and thus only the measured outcomes would be observable by an external observer. So the state where a spin had been measured to be in one state but could also be in another state would never exist, not even to an external observer and there would be no paradox and no refutation of the block universe.

    We live in a world where tangible objects exist and thousands of years ago 'Atoms' were contemplated. Today we look inside Protons and see a Sea of itinerant objects. What is an object but a manifestation of an energy packet? A Proton is an emergent effect of the continuous energy fluctuations within which some how results in a 3 Quark manifestation. How and Why Lord only knows, Physics gave up deep thinking 70 years ago. The point is though: if even a single Proton is undergoing continuous internal change then what price the idea of position and momentum being determinate in the first place? We are only scratching at the rusty hull of what has been found thus far. It might help if Physicists started thinking for a living instead of just spouting the text of popular paper backs. No criticism here intended for this video as I found it quite thought provoking ... It is the block heads who just sit on the beach watching the waves go by and drawing their salary for such little effort.

    The block universe can still exist in quantum physics. You just need many worlds, i.e., instead of a block corresponding to one particular timeline, the entire phase space of all possible quantum states exists as a block universe and we move through it a manner that seems random to us. This is almost a kind of generalization of relativity, as the particular outcome of a quantum experiment is relative to the observer's location in the wavefunction.
    There is no universally real timeline: no sequence of quantum eigenstate is privileged over any other. Hugh Everrett even called it his "relative state" formulation of QM. This is also what the Wheeler-deWitt equation predicts, an eternal superposition of every conceivable quantum state that never collapses. It's an incredibly elegant and logical picture of the universe, if you ask me. Everything everywhere for all eternity. If I were a religious man, this would almost seem to me to be the perspective that God must have looking at the universe from the outside.

      One of the main criticisms of the "Many Worlds" interpretation is the following. If a particle has a 61% probability of being observed in location A, and a 39% probability of being observed in location B, the "Many Worlds" interpretation needs to say that the particle is in location A in 61% of the universes, and that it is in location B in 39% of the universes. However, the "Many Worlds" interpretation can’t explain why the split occurred with this particular distribution, unless we add extra assumptions to the theory.
      This does not necessarily make the theory wrong, but adding these extra assumptions takes away the main argument in favor of the “Many Worlds” interpretation, in that it was thought to require fewer assumptions.
