    I have Carlo’s book and got somewhat lost when he got onto the subject of entropy. This talked helped a bit as I now understand that my ability to conceive anything further is naturally limited by the ingrained experience of existing in the low entropy of the biosphere! 🤣

      Hi there. His explanation for why watching a movie backwards doesn't make sense explains this. Also, that's because, like he said, time flows in the cause before effect order. The arrow points in that direction and can't be reversed...nor go both ways, I assume.

  • @Robinson8491
    @Robinson8491 2 ปีที่แล้ว

    I like how I now realize Einsteins first realization that started it all was basically a form of Time Dilation in the shape of the impossibility of determining simultaneity with two clocks, which is exactly what is happening with time dilation in gravity. So it ended (General Relativity and time dilation as gravity) with where it started (the impossibility of two synchronous clocks). Kind of poetic, such as is life mostly indeed.

  • @Sgt-Gravy
    @Sgt-Gravy 6 ปีที่แล้ว +1

    Star date is not only a measurement of time, but also a reference point? Is time based on movement, heat, or energy; if an object is at absolute zero is it "frozen in time", or doesn't experience time because "it" the particles that make it up, are not covering distance within space/time? The big bang, the first energy, the first movement,... started time?

    • @philproffitt8363
      @philproffitt8363 5 ปีที่แล้ว

      I think items at, or close to, absolute zero (zero Kelvin) in the universe can still be anything up to 13.8 billion years old. Just because they don't have thermal energy doesn't mean they stand still against our time reference. Any time-dilation relative to us would be down to velocity/gravity effects...not temperature. But after this lecture...I believe we should stop referring to 'time' as a property of space and the universe...it's just a human concept with our units of measurement. Those measurements are not universally constant. We should perhaps invent a new word to describe the 'progress-of-the-universe' or any property/dimensionality we attribute to it. Our particular time/date stamp is only relevant to our time and place...not to anything we observe in the universe.

    1. i thought i was struggling to grasp a few bits here and there, but now hearing the audiences questions, wow, its as if they werent listening at all.
    2. cant all the questions be answered by the same idea (which somehow Carlo avoided stating): causality and entropy still exists to drive a process of change (which generates in our mind a distinction between a thing that was and a thing that now is), but these fixed perceptions of time are an illusion. in this sense, time is a human construction based on experiencing entropy. why do we all have this illusion? because its more evolutionarily advantageous to interpret a "flat" time that can easily predict immediate threats than it is to pontificate about the universal meaning of time.

  • @nsjx
    @nsjx 6 ปีที่แล้ว

    multiple "big bangs" would suggest a lack of linear time in the place of what we call 'entropy', or that at the most the human notion of Time as a real 'thing' is simply the measurement (or interaction) we human brains affect upon our surroundings to make our version of "sense" out of our very REAL multi-dimensional existence. there was a good book called Flatland and then a companion book called Sphereland, where the author (making great use of satire) helped the reader (a being mostly perceiving 3 dimensions) understand the ("limited") perception a being would have in a 1d space and a 2d space. the companion book took this further and helped the reader try to understand how a 2d being could POSSIBLY fathom the 3d world. the real goal of both books combined was to get the reader to imagine our perception of hypothetical 4th dimension. i think science is on the threshold of doing just that. the way we interact with our "reality" may very well change soon in ways most of us could never predict.

  • @KomissarLohmann
    @KomissarLohmann 5 ปีที่แล้ว +1

    The second question shows how people still stick very strongly to the "sensuous" conditions of experience. Time in its most ancient definition is the observation of change, even if this changes are so small that they are imperceptible to human eye and everything looks like it hasn't changed. All the history of science, since the first philosophers up to this day, have proven that, although very practical and efficient in our everyday lives, mere observation does not provide a reliable scientific explanation of any phenomenon. As Hegel said, if sensuous experience we're enough to explain anything at all, science would be useless and never have been invented.

      They are a personal perception of where you are. Just like Earth as a whole is always in the same place so earth has it's own universal, or personal time within the universe.
      We measure time based on our position "relative" to the sun, but atomic clocks base their time on movement of atoms.

    You can't ever detect half a Planck length because there's no equivalent constant naturally derived from the Observable universe 's mathematical-modulated integration. Ie what we can see is integrated.., so it "maintains " it's embodiment of integrity, something like the leaves on a tree have individual and collective integrity within specific limits, it's a mathematical property of inclusion and exclusion of primes and cofactors, from which the cause-effect, (total internal reflection-embodiment), is a connected individual and collective conglomeration of phase-states. (Humans are analogue, made of time-duration quanta, and use analogies to communicate and infer what can be from what is, but if the Universe is a single connection, these analogous approximations can never be "true" reality)
    The Planck length is an inferred value so any amount of division is possible in the quantizing function of temporal connection-continuity, but by self definition, the duration is too short to relate to the existing resonant general probability of phase states.
    A thought experiment might be to imagine compressing a simple gas like Hydrogen, the faster, (= higher frequency), you compress the higher the radiation (by the Exclusion Principle) frequency will be, so if you use a supercollider like the LHC, it is a tool limited by the elements and available energies of its construction, and to get at the Planck length frequencies requires a collider as big as the galaxy(?).
    The cause-effect resonance of the Planck length comes directly from quantum effects of superimposed timing that is, ..the Universe.
    The Present, Now, is the cause-effect of reflection in the limit of connection of QM-Time "suspended" in nothing, eternally, which is an alternate self-definition of spaced timing, potential and transitional dimensions measured as resonance.
    All possible phase states of time-duration resonance are occupied.., by the cause-effect observed as the Exclusion Principle, =>Quantization of Eternity-Now, "measured" out against itself in self-definition. A beginning is also an ending, a cause-effect recirculating Origin like the starting-finishing line of a circular racetrack, that measures time duration against potential possibly of all rates and durations, in that particular dimensional context.

  • @edwardjohnfreedman4274
    @edwardjohnfreedman4274 3 ปีที่แล้ว

    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.

  • @gaztech1935
    @gaztech1935 23 วันที่ผ่านมา

    Time as we understand it is obviously flawed to a certain degree, to understand time we would probably need to fully understand gravity fully.
    Some scientists believe the universe is digital in nature this seems to be the way everything is ruled, code in particular seems prevalent when observations are made at the Quantum level.
    An experiment using the double slitt method where light changes from wave to paricle but only when observed was done with light coming from a distant galaxy and as before the photons changed when viewed this is very interesting and implies the light changed at its source back at the galaxy it originated at many thousands of years ago what does this suggest about time.

    Imagine an observer X measured a Planck length and got the result, say A. At the same time, I was moving in a way close to the speed of light and "seeing" the measurement process. I would get a smaller number than X based on length contraction in Special Relativity. The more I got close to the speed of light the shorter the length that I would see. Right?

    I always think about this stuff when I watch Star Trek and they start the episode with "Captains log, stardate 45368.2". How in the world could they compute that with ships flying all over vast distances at extremely fast speeds. The "Full impulse" speed they use is close to light speed without warping space. Warp speed probably makes things even worse. I always thought the logs should be based on mission time... that is to say "time elapsed since we launched in the small frame of our ship". That, with other data (relative speed and gravity), should allow them to translate that time to a differnt external reference of time after the fact.

    how is it we assign an age to the universe, if time is not constant?

    • @philproffitt8363
      @philproffitt8363 5 ปีที่แล้ว +3

      (I think) The age we assign to the universe is calculated by using all our astrophysical observations, and the constant value of the speed of light, to wind back the clock in relation to our 'standardised' date/time reference. We may say 'time' is not constant...but I think it would be better to say that our 'measurement-of-our-human-concept-called-time' is constant (and our timepieces are constant, subject to design accuracy). However, the 'progress-of-the-universe' (entropy etc...) is not constant...it is dependant upon the 'gravitational situation' created by the proximity of mass and/or velocity. Therefore an object, like a wristwatch...or a person, basically progress (or decay, deteriorate etc...) at different speeds relative to the 'standard time reference' because their gravity/velocity situation is varying in relation to the 'reference'...a real world example being high altitude/ high speed travel etc...and GPS satellites, whose clocks run at a different speed up in orbit...this has to be accounted for or things like satnav would not work at all. What I take from this lecture is that the 'Time' we experience in our brains, and devices we build to measure and record it's progress and our history, is not any kind of entity/property/dimension of the physical universe...its just a unit of measurement we created to reference events...just like we created units of length, measurement etc...to navigate. A mile or kilometre is not a property of the universe...neither is 'time'...they're just human measurements to record our progress, get about and synchronise our actions.

    The fact that this talk transcends the boundaries of physics and metaphysics is really unfortunate. Because the audience isnt well-versed enough in either discipline to be able to parse between which aspects of the speaker's talk fall in which category. Thus opening a vast corridor for the emergence of pseudoscientific interpretations.

    but what about the thing from stephan hawkings books, simultaneousness. where it is describing how you can see the "past" and the "future" by either moving very very fast or "looking" very very far. (because if u dont move through space, you move with c in time in the 4 dimensional space time, and you perceive that spacetime in a 90° degree angle from your movement direction). that should not be a thing if quantum gravity is true, right?
    in quantum mechanics/relativity this is certainly true.

  • @bradleywhitaker1085
    @bradleywhitaker1085 2 ปีที่แล้ว

    The notion that sews this whole presentation together is "perception/observation" which is ever present in quantum mechanics. While much of quantum mechanics has been proven (or at least demonstrated) I have never been confortable with the idea that the nature of reality is dependent on our observation of it (I am not a trained physicist). Dr. Rovelli completely discounts the possibility of the same moment existing in any place in the universe apart from observation. And observation is, of course, dependent on the speed of light. Is this provable? Does this make sense? Not to an untrained mind for all the reasons he discussed. i need to explore the quanta nature of time further. This may be another notion which is is not obviously provable.

    Reflexão - Aprendendo com o Pai Criador - YHWH - 26
    O tempo - o sexto sentido. Sentindo o tempo pela visão.
    Dizemos: "olhamos" para o passado para "vermos" o que passou. "Olhamos" para o futuro para "vermos" o que passará.
    Dos cinco sentidos, a visão é o elo de ligação entre nós e o meio externo. É a primeira porta por onde saímos em busca do conhecimento.
    Através dela, buscamos respostas para tudo aquilo que enxergamos. Daí a afirmação da ciência de que a visão é o sentido da cognição por está diretamente ligada ao saber.
    Por sua vez, o saber demanda "tempo" para ser "achado". Dependendo do que precisamos saber, a "duração" é maior. Quando "batemos" os olhos num objeto e imediatamente o identificamos, o tempo praticamente inexiste. Já quando nos é desconhecido, "demoramos" mais pra identificar.
    Por isso, a individualidade e a relatividade, pois depende exclusivamente de quem o demanda.
    No momento em que tomamos posse do conhecimento, o tempo se torna irrelevante, pois saciamos a nossa curiosidade e não precisamos de mais "tempo" para encontrá-lo.
    O tempo é o evento duradouro que vai do instante que a Luz nos toca até o momento que deciframos a informação chegada.
    A Luz, o tempo e a visão são partes do mesmo todo.
    É o delay criado pelo Pai Criador para possibilitar a formação de nossa realidade. É através do tempo que firmamos o conceito de nossa existência e da força Criadora do Pai.
    Assim como a sombra é parte integrante do objeto bloqueado de luz, o tempo é a sombra da nossa visão enquanto bloqueada de saber.
    O que quero dizer é que o tempo só "existe" enquanto inexistir o conhecimento para nós. Enquanto não decifrarmos a informação trazida pela Luz, maior o tempo para apossarmos do conhecimento e, Dele.
    A física relativística e a mecânica quântica estão certas enquanto definições matemáticas sensoriais. Apenas mudanas e dentro de cada contextualização estudada.
    A ciência ao afirmar a inexistência do tempo já apossou-se do conhecimento de que precisava. Entretanto, o que parece, é que lhe falta tempo para aceitar Quem a municiou de conhecimento.

    Spacetime is a standing wave comprised of nested spirals passing through itself in both/many directions. The more of a complete coil/cycle/interaction you can perceive together, the more it manifests superposition and simultaneity. This is how it seems so obvious in short small interactions like particles, but it can still be found in longer/wider oscillations that you might otherwise call "history" or "expectation." When the standing wavelength is small in one dimension but long in another, you might call it "spooky action at a distance" or "strange intuition."
    You have to use a waveform-based math rather than a linear one, then it solves out. You just may not like the answer at first.

    I think people are trying to pull something practical from what he is saying without getting into crystals, law of attraction, vibes, etc. Things always change, live for now has been practiced by some for ages. Perhaps these truths of time are against our systems - government, social, religious... Now just another reason to attempt to dismantle in the face of monetary, power gains. Also, does he go into decoherence which is a very real part of quantum physics that would tell us individual concrete structure is existence. But I have a feeling he magnifies the mystery so people will try to imagine a completely different world possible and how to get there - tool of the charlatans.

    I never got that "it's the same as asking what's north of north pole" analogy... because if you stood on the north pole, "north" would be up - and in order to do that you have to go one dimension up, where the terms north and south become meaningless. Interesting approach to time and quantum gravity though. Anxious to hear what Sean Carroll's group comes up with :)

      North would not be up because North and South are decided by the flow of Earth's magnetic fields in relation to the surface of the planet. There is no North of the North Pole, because North is a placement term. And because of the direction of magnetic flow, if we did decide upon a North beyond the pole, it would be *down* from the pole, towards the core, not up.

      I think I understood where my thought process is different. I went with stelar north, not.. geo-north (?:) - I mean what I imagine is you take the north start, you track it till it's directly above you (which I presume it roughly is in the north pole:), and that's your new north.

    We can have 'time' with an emergent process based on: (E=ˠM˳C²)∞ with energy ∆E equals mass ∆M linked to the Lorentz contraction ˠ of space and time. The Lorentz contraction ˠ represents the time dilation of Einstein’s Theory of Relativity. We have energy ∆E slowing the rate that time ∆t flows as a universal process of energy exchange or continuous creation. Mass will increase relative to this process with gravity being a secondary force to the electromagnetic force. The c² represents the speed of light c radiating out in a sphere 4π of EMR from its radius forming a square c² of probability. We have to square the probability of the wave-function Ψ because the area of the sphere is equal to the square of the radius of the sphere multiplied by 4π. This simple geometrical process forms the probability and uncertainty of everyday life and at the smallest scale of the process is represented mathematically by Heisenberg’s Uncertainty Principle ∆×∆pᵪ≥h/4π. In such a theory we have an emergent future unfolding photon by photon ∆E = hf with the movement of charge and flow of EM fields. This gives us a geometrical reason for positive and negative charge with a concaved inner surface for negative charge and a convexed outer surface for positive charge. The brackets in the equation (E=ˠM˳C²)∞ represent a dynamic boundary condition of an individual reference frame with an Arrow of Time or time line for each frame of reference. The infinity ∞ symbol represents an infinite number of dynamic interactive reference frames that are continuously coming in and out of existence. At the smallest scale the Planck constant ħ=h/2π is a constant of action in the dynamic geometrical process that we see and feel as the passage of time.

    Very disappointing Q&A session. Has anyone in the audience grasped the time illusion of continuously future-forecasting brains which visit a block universe along a necessarily statistically oriented path?
    Consciousness belongs to any continuously future-forecasting system, independently of its material support

    Time looks to be one dimensional, for me as a human being, though it might not be.
    If time having two or more dimension could explain to me some of the weirder stuff that happens,

    Time does not exist. It is a human construct to measure relative movement between two or more objects. Save an hour and a half and do something else with "your" time.
