    We live in a universe with 3 dimensions of space and one of time. Up, down, left, right, forward, back, past, future. 3+1 dimensions. Or so our primitive Pleistocene-evolved brains find it useful to believe. And we cling to this intuition, even as physics shows us that this view of reality may be only a very narrow perception. One of the most startling possibilities is that our 3+1 dimensional universe may better described as resulting from a spacetime one dimension lower - like a hologram projected from a surface infinitely far away.

    The holographic principle emerged from many subtle clues - clues discovered over decades of theoretical exploration of the universe. Over the past several months on Space Time, we’ve seen those close clues, and we’ve built a the foundations needed to glimpse the true meaning of the holographic principle. We’ve moved from quantum field theory to black hole thermodynamics to string theory. We’ve made a background playlist if you want to start from scratch, and I especially recommend catching last week’s episode. But this is tough material, so let’s do a review.

      There are 6D or 7D hyperspace + common 4D = 10D or 11D spacetime. To provide symmetry, there are 6 or 7 aspects of 'regular time' + 4A 'hypertime'. See Seal #3: Unified String Theory 21 or 19 Dimensions & Aspects of Spacetime.

If ones hits up glossary for physics books or perhaps a physics dictionary they will find many of this seemingly complex stuff melt away as it tends to be a lot of grand ideas, about grand things but made of relatively simplistic pieces with complicated sounding names.

      Any dimension past time can only be one of thought or consciousness past "3-d" is all consciousness.... consciousness needs an "avatar" or body to experience this portion of reality. This is how you know consciousness is eternal. We could not exist if it weren't. You could say souls or consciousness are "packets" of information that have become bigger than regular "information". Cyberspace in our own network here in 3'd land is a facsimile of the "cyberspace" of "reality". WHich all consciousness flows through from the Source or God or the Truth. Scientists are trying to explain the consciousness part of reality with physical mathematics which is impossible... it cannot be represented here. Only theorized at. That's why they are called met physics.

    An astonishing good comprehensible, though deep explanation. Another hint of the holographic principle (similar to the Bekenstein entropy) is that the event horizon of a black hole is proportional to its mass and NOT proportional to the third root of its mass.

    • @monkieassasin
      @monkieassasin 2 роки тому +1

      Another hint: If you took all the mass-energy of the observable universe, and compressed it to a point to create a black hole, the Schwarzschild radius of that black hole would be the cosmic event horizon.

      In fact, programming language may be the best way to explain this video...
      We are technically the code, yet we experience the virtual reality world made by the code.
      Our attempts to reverse engineer the code and the hardware may be impossible from our perspective, so we cheat / do it the hard way; we make models and come up with languages of it and keep reverse engineering until we make a virtual machine and code that matches.

    • @TheColemancreek
      @TheColemancreek 5 років тому +2

      @@Alienami I wouldn't exactly try to explain the Holographic Principle as us living in a simulation, nor reality being just a hologram. It's more the idea that our 4 perceived spatial dimensions might be in reality just 1 (I am personally not on board with this idea, which I will explain in a bit). It all basically comes down to the notion that in order for quantum mechanics to work (it is the most tested and precise science in existence), information in the universe cannot be lost. This "information" can be thought of as an equation that gives a particle causality and a somewhat defined future path -- a photon's end point location cannot really be surmised in exact details, but information in it's wave function gives you a general idea of it's end location. When matter (information) falls into a black hole, this information is seemingly lost. That kind of fubars everything that we understand about reality, time, space, even causality. Since time can be viewed as the 4th dimension, and particles (and their encoded wave function) also travel forward through time, a few theoretical physicists came up with the idea that reality might just be 1 dimensional and the 3 other dimensions we perceive just an illusion. It's doesn't mean we are living in a simulation, program, etc.
      A way to get around this absurd notion (at least in my mind) is to assume that all black holes have an exit... that the matter/energy/information always comes out somewhere else. This makes them not violate the 2nd law of thermodynamics. Within Eienstien's theory of Special Relativity wormholes are possible. The birth of our own universe could have been such an event -- information coming out of a white hole that is connected to a black hole through a wormhole. It's a much more elegant and simple explanation, but I don't see anyone being able to prove this unless humans can craft a machine that would survive the voyage beyond the event horizon, which is very very very very unlikely. If a probe could survive the passage and come out the other side, it probably wouldn't even end up in our universe.

      Yeshua Immanuel Christ
      🐟 05. THE PHENOMENAL UNIVERSE:
      The fact that the external, phenomenal universe (“prakṛti”, in Sanskrit) of names and forms (“nāmarūpa”, in Sanskrit/Pali) exists solely within personal consciousness (and by extension, Universal Consciousness), 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. 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”).
      The late, great Professor Dr. Alan Watts’ response to the question: “where is the universe located?”, was: “nowhere and everywhere”.
      This phenomenal manifestation is composed of 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 is not included in this system, as cosmological science has yet to determine its structural composition.
      The five gross material elements and three subtle material elements are (from most gross to most subtle):
      SOLIDS (AKA earth - “bhūmiḥ” or “pṛthivī”, in Sanskrit) are made of densely-packed atoms and molecules of a steady shape at room temperature.
      LIQUIDS (AKA water - “jala” or “āpaḥ”, in Sanskrit) are composed of moderately dense molecules (usually including at least some water) of no fixed shape.
      GAS (AKA air - “vāyuḥ” or “marut”, in Sanskrit) consists of rarefied atomic particles of no fixed shape.
      HEAT (AKA fire - “analaḥ” or “tejas”, in Sanskrit) is made of kinetic energy (which may or may not 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 possess a mind, but function purely on base instincts, originating from their genetic code, via a rudimentary nervous system.
      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 (in this case, the illusory, ephemeral self-identity). Only humans possess the self-awareness necessary to question their own existence. Read Chapter 10 for a full elucidation of egoity.
      Each of the FIVE gross 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 is the Universal Self (“ayam ātmā brahma”, in Sanskrit). That explains why we say: “This is my body” or “I possess a mind”. Who is the owner of the body and the mind? It is us, the anti-matter, the inextinguishable authentic self/Self (“ātmana/Paramātmana”, in Sanskrit). Ultimately speaking, the Universal Self alone is.
      HOWEVER, all eight elements are in fact “made” of Consciousness, since, as demonstrated previously, naught but Consciousness exists. Consciousness is the ultimate reality (“prajñānam 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 Awareness.
      Although The Absolute cannot be verbally-described, (otherwise, it would be an OBJECT), as a concession to materialists, Infinite Consciousness has 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; Conscious Knowledge; and Perfect Peace (often translated as “bliss”. However, the term “bliss” connotes an ephemeral experience of euphoria, whereas “peace” is the absence of any form of temporal suffering).
      Because Absolutely Nothing (“Brahman”, 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 ‘becomes’ 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 an attribute 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).
      The phenomenal manifestation is eternally cyclical, because ‘coming into existence’ implies ‘going out of existence’, just as ‘black’ implies the existence of ‘white’, or as ‘rich’ implies ‘poor’. Is it possible to have something without nothing? Obviously not, because the two go together, as interrelated opposites.
      Similarly, despite what most believe, the outer-world is as much the Self as the inner-world. Where is the boundary of the human body? When we look at a person, we cannot see that person UNLESS we also see the background image. The two are inseparable, just as a flower and a bee cannot exist without the other. This fact alone is ample evidence that the universe is a holistic and wholistic system or entity.
      You who are reading these words are that Totality of Existence, the Highest Universal Principle, the Essential Irreducible Self.
      In common parlance, you are God (IF you only knew it!). Most of the greatest sages in history have spoken about either or both these concepts (of the Absolute Truth being either Absolutely Everything or Absolute Nothingness), such as the concept of “form is emptiness and emptiness is form” in Buddhism, or in Avatar Meher Baba's book “The Everything and the Nothing” (which is highly-recommended, particularly Chapters 51 to 56, which poetically describe the Ineffable One-without-a-second). Even an ordinary writer, American author Kurt Vonnegut, once penned: “Everything is nothing - with a twist”.
      The Stanford Institute for Theoretical Physics professor, Doctor Leonard Susskind's so-called “minus-first law of physics” states that information is INDESTRUCTIBLE. This is akin to the law of conservation of energy in classical physics, and proves that neither physical or psychic energy is lost. Read subsequent chapters to learn more about how this law relates to the notion of reincarnation, as well as to miraculous phenomena such as savant syndrome.
      The planet on which we are residing consists of animate/organic life, as well as inanimate/inorganic matter.
      The six stages of ORGANIC life are:
      1. conception/birth
      2. growth/development
      3. maintenance
      4. reproduction
      5. ageing/deterioration
      6. death
      British polymath Thomas Young's famous double-slit experiment suggests that matter exists purely as potentiality or as a "possibility" until it is observed by a conscious being. This phenomenon, known as the wave-particle duality, is often discussed in advanced spiritual discourses, as it gives credence to the primacy of Consciousness. There are other aspects of the universe (e.g. the various philosophical approaches to the nature of ontological time, the accelerated expanding universe, holographic universe principle, quantum superposition, wave function, and quantum entanglement), as well as the possibility of life on other planets, the crop circle phenomenon, and the presence of the Fibonacci sequence in nature, which are beyond the scope of this document, and which do not directly relate to the most exigent thing in life (to find the unending peace/happiness which we humans are ULTIMATELY seeking).

      “Find out who you REALLY are so that when death comes…there is no-one to kill, for while you are identified with your role, with your name, with your ego, there is someone to kill. But when you are identified with the whole universe, death finds you already annihilated and there’s no-one to kill”.
      *************
      “Just as you depend on the universe, so too does the universe depend on YOU.
      Everything depends on everything else.”
      Professor Alan W. Watts,
      British-American Philosopher.

After that she says that, after interviewing hundreds of government people, she sees no evidence for all the UFO stories. To her it feels very much like other CIA disinformation campaigns. Worth watching, especially for the first half.

      Original comment is about the complexities in describing and sorting thru the possibilities that our universe is a holographic projection. The malstrom of ideas is confusing and hard to follow.
      In response I made a joke using a well known comic meme about misunderstanding the simple by overcomplicated misinterpretation.
      What I said was we are inside of and a part of the holographic projection trying to figure out how that projection works. I then state the issue of the curvature nature of the projection may only be dependant on and relative to where the observer is.
      I am saying the projector of our holographic universes is a 'black hole' of a kind.
