      Ane Håkansson sorry I need an answer to the question at my comment if u can.
      If gravity is not a force (rather a geodesic as explained in the video), why do things accelerate when falling.

      @anehakansson7771 5 років тому +22

      @@yohanalaiser2667 I'm not sure I follow you here but let me give you my interpretation of your question. Let's stick to massive particles since massless particles, although they follow geodesics, do not accelerate. Massive particles, not influenced by forces, allways follow geodesics. In Newtonian geometry, this necessitates the introduction of a gravitational force in order to curve a particle's straight trajectory around a massive object, i.e. forcing the particle to accelerate. The idea of general relativity, on the other hand, is that these geodesics are curved in the spacetime near massive objects and, as a consequence, the notion of a gravitational force has no longer an explanatory function.
      In summary, the acceleration is still there but has its origin not from a force but from the interaction between the massive body, the particle and spacetime, alltogether creating a curved geometry embedding the particle's trajectory.

      "All this- whatever exists in this changing universe, is pervaded by consciousness"
      --Isa Upanishad .5000-BCE.
      Consciousness is the intelligence, the organising principle behind the arising of form. The quantum field or pure consciousness is influenced by intention and desire.
      There is a deep connection between consciousness and matter. The quantum double slit experiment has shown that a measured electron can appear either as a particle or a wave, but NOT both at the same time.
      Consciousness shapes our material world. DNA is a transceiver of information, some from the space time dimension and the other form the quantum world.
      The cosmos is made of events of the mind. The act of observation bonds the observer and the observed. Anything you observe becomes part of your reality. All things are connected and act as a single organism. This connection is undiminished by time and space. An action at one end of the universe is this felt at the other.
      Quantum rules does not care for Newton’s third law, which states that every action has an equal and opposite reaction. Quantum rules dictate that every action has a multitude of reaction possibilities.
      The brain receives info about its surroundings in space. After comparing new information with old memory, the brain sends it on via quantum connection to the dimensions that await its information. The brain needs REM sleep.
      The brains job is to maintain the physical portion of the link, between the body and consciousness.
      All matter is electrical in nature. In quantum physics an electron is a point particle, because it occupies no space, and is thus a imaginary mathematical point.
      If all the atoms in the world stopped moving, the world would disappear. ..
      Every human is a quantum matrix-a myriad of interlacing processes in constant flux. In nature there is nothing like a circle, it can only be a vortex spiral with ever changing evolution-nothing can remain same for ever and till ad-infinitum.
      The quantum world thus transcends time and space. Virtual particles have free access anywhere , everywhere , everywhen. Since our wolrd is 4 dimensional, the quantum points can arrange themselves in anyway. They get instructions from the transceiver called DNA. A male and female contributes ½ of the DNA to produce a new born.
      Consciousness creates our space time. Since quantum stuff reacts to consciousness, the universe is constructed by consciousness. By adding the dimension of time to 3D space, our consciousness is given the ability to evolve.
      In quantum physics it is meaningless to think of a particle having a trajectory through space. For in the quantum world all things are possible. It is the same in this space time world till choices are made. Most of these choices are automatic, as they are made necessary by the past.
      Matter is not condensed substance but a diffused form of energy.
      Newton’s classical law of Inertia states that F=MA ( the basis of the first world war ) M=mass A= acceleration. In the quantum ZPF Inertia is just the resistance, or the drag that objects experience, when accelerated .
      Gravity is a push, NOT a pull.
      The virtual photon flux between a dipole and the vacuum ZPF is what the scalar waves are. Scalar waves are faster than light with no loss of energy.
      All thoughts- attitudes, decisions, concepts, alignments, agreements, polarized struggles etc are constructed holographically in the brain. Identities that create experience are created holographically as personas, sub personalities, and archetypes, and as polarised constructs in the deeper mind.
      "All material and spiritual phenomena of the universe are present in the individual. Similarly, all those present in the individual are also contained in the universe. This is how the wise desire to perceive."
      Every atom within us depends on the rest of the cosmos.
      We are NOT independent from this cosmos. We are part of it. This is the reason we must live in harmony with the laws of the universe by exercising our free will.

Accordingly, INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/PHYSICAL EXPERIENCE; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/energy is gravity. It ALL CLEARLY makes perfect sense. Gravity IS ELECTROMAGNETISM/energy. E=mc2 IS F=ma. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=MC2 IS F=MA. GREAT !!! Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 is F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Consider THE MAN who is standing on what is THE EARTH/GROUND. Touch AND feeling BLEND, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The stars AND PLANETS are POINTS in the night sky. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the rotation of WHAT IS THE MOON matches it's revolution. Great. MOREOVER, a given PLANET (including what is THE EARTH) then sweeps out equal areas in equal times consistent WITH/AS F=ma, E=mc2, AND what is perpetual motion; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. INSTANTANEITY is thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Stellar clustering ALSO proves ON BALANCE that E=mc2 IS F=ma, AS ELECTROMAGNETISM/energy is gravity. Objects (including WHAT IS the falling MAN) fall at the SAME RATE (neglecting air resistance, of course), as E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/energy is gravity. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. THE DOME of a PERSON'S EYE is ALSO VISIBLE. (Notice the flat AND black space of what is THE EYE.) The stars AND PLANETS are POINTS in the night sky. The sky is blue, AND the Earth is blue. THE EARTH/ground AND THE SUN are E=mc2 AND F=ma IN BALANCE, AS ELECTROMAGNETISM/ENERGY IS UNIVERSALLY PROVEN TO BE GRAVITY in what is a mathematically unified fashion. E=mc2 IS F=ma. The middle distance in/of/AS SPACE AND the full distance in/of/AS SPACE are NECESSARILY linked AND balanced. MAGNIFICENT !!!!!!!!!! INSTANTANEITY IS thus FUNDAMENTAL to what is the FULL and proper UNDERSTANDING of physics/physical experience, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. It is ALL CLEARLY proven. Again, the stars AND PLANETS are POINTS in the night sky. GREAT. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It is all CLEARLY proven !!!!!!!! TIME is NECESSARILY possible/potential AND actual IN BALANCE, AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. GREAT !!!!!!!! BALANCE and completeness go hand in hand. By Frank DiMeglio

    This topic is complicated for many people, because they don't know anything about geometry. But you gave the example of a piece of paper, which can be easily wrapped around a cylinder, but not around a sphere, because sphere doesn't have zero Gaussian curvature. Your video is super beyond limits. You covered different topics in short time with clarity and logic.Your way of explaining ideas is remarkable. Sir you are very excellent teacher.

    • @hypercatsinspace7625
      @hypercatsinspace7625 5 років тому +4

      According to Richard P Feynman, it has to do with the way a quantum particle interferes with itself as it moves from one point to another. It takes all possible paths, but the wave functions of paths that describe long travel times cancel each other out, leaving only the function describing the path of shortest time, thus the particle takes this path. This is an 'In a nutshell' description of the phenomenon, and reality is more complex than this.

    • @zachstar
      @zachstar  5 років тому +4

      haha I appreciate the comment! I mean I did well in school and I enjoy learning new things but yeah these videos come with a ton of research. A lot of what I discussed here I didn't know about until 2 weeks ago so I'm learning as I go for sure. I've also gotten some personal help from people way more educated than I (for example in this video I had a physics grad double check my metric tensor example) so it isn't JUST me. But overall I think the video on conic sections and the one on imaginary numbers were the only videos in the last year where I knew most of what I discussed in the video due to school or videos I've watched in the past, everything else starts with me doing a google/youtube search or reading a book and continuing from there.
