You're clearly not high enough...the only way to expand your understanding is to change how you experience reality... Also, math is a language to express things not well articulated in other languages outside of programming languages, anyway. 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]

@@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.

The holographic principle is also a perfect example.: there's this concept called the Akashic Records, which is generally dismissed as mystical hoo-doo, but look at what is says. It states that the entire history of the universe (our 3-D universe, that is) is recorded on a sacred scroll (that would be a 2-D surface) somewhere out in the realm of the Gods (i.e. - the farthest reaches of the creation). Are we making a scientific breakthrough, or are we just using fancy mathematics to come full circle back to what some ancient philosophers speculated?

[@TheWorldTeacher]

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.

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.

Matt - this was very well done, I enjoyed it immensely. Long ago, when I was receiving training in hyperspace mathematics (which is now beyond my abiliy, due to both severe head injury as well as the passage of decades), I was of the firm opinion that a degree of freedom and a dimension were one and the same thing - all that differs is your application of the math. Likewise Prof. Witten's work shows that five very different systems of string mathematics represent an identity of structure - they are alternate views of the same structure. I find this sort of thing is not rare in physics or mathemetics (which after all, is the fundamental language of physics) hence -

[@christianyaerger1751]

I'm sorry to hear about your injury. :( I've recently been considering "time" to be yet another dimension of space, simply pinpointing the location of an object along its worldline. To your understanding, would this be an accurate assessment at all? Or completely false due to the maths?

[@deandeann1541]

@@christianyaerger1751 Yes, that would be an accurate assessment. An object's address requires x,y,z and its location in time. Else you will not find the object. On a graph, math treats time just like any other dimension. Physics also treats time like other dimensions, the laws of physics work as well with time reversed. A difference though - is that our minds experience time as a constrained dimension - the constraint being our sense of experience can move only in one direction. This is very much like the constraint experienced on the vertical axis when an object descends below the event horizon of a black hole. It is fun to consider what happens to the time axis under those circumstances (and why).
