      there is no example in nature of a massive sphere or any other object which by virtue of its mass alone causes smaller objects to stick to or orbit around it. try spinning a wet tennis ball or any other spherical object with smaller things placed on its surface and you will find everything falls or flies off and nothing sticks to or orbits it. to claim the existence of a physical law without a single practical evidential example is hearsay, not ''science.'' gravity is a myth.

      How can you call yourself a scientist, if you can't handle criticism? Part of the scientific method, is falsification. It holds that every theory is falsifiable based on new observable evidence. This is particularly true when technology is constantly creating new scientific instruments capable of providing new data never seen before.Einstein's theories should be just as falsifiable as any other scientific theory. Perhaps the "anti-relativity email" you refer to is not valid, but, that doesn't mean something valid isn't out there. Until a theory of gravity that works comes along, every theory of gravity should be considered.

    @damienasmodeus928 Год назад +1

    I have a suggestion of what quantum theory could be.
    It assumes that multiverse interpretation of quantum mechanics is true and there is no such thing as collapse of wave function.
    Instead collapse of wave function is simply entanglement of observer with the particle, that's why from his point of view it looks like wave function collapsed, but it didn't.
    If this is true then we can calculate gravitational influence of a particle as an bending of spacetime in all quantum multiverses simultaneously.
    This theory would also explain existence of dark matter, as an influence of particles from other universes on our universe.
    This theory is also experimentally testable.
    Here is experiment to determine if it is true:
    Put 1 heavy object whose gravitational influence you can detect into an empty space. Put device onto the object that would detect quantum state of spin of a single particle.
    Make the wave function of the particle collapse. If the spin goes up, device will push the heavy object with some force to the left. If the spin goes down, device will push the heavy object with some force to the right. According to theory, what we did here is that we entangled the heavy object with the quantum state of the spin of the particle and if that theory is true we should be able to detect that the heavy object suddenly have 50% gravitational influence and at the same time there would be created bubble of dark matter with the rest of 50% gravitational influence of the heavy object going in opposite direction as the object, because the dark matter would be simply the same object in another universe.

      ON THE NECESSARY, TRUE, AND ABSOLUTE PHYSICAL ESSENTIALITY (IN AND WITH TIME) OF THE FACT THAT E=MC2 IS CLEARLY F=MA:
      Consider the EXPERIENCE of THE MAN (then involving WHAT IS THE EYE) who is suddenly exposed in what is outer "space" in BALANCED RELATION to the clear fact that E=mc2 IS F=ma (INCLUDING WHAT THEN CONSTITUTES the EXPERIENCE of both the Sun AND WHAT ARE THE POINTS IN THE NIGHT SKY). This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE, AS E=MC2 IS F=MA; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.) SO, the Earth constitutes the FULL DISTANCE in/of SPACE in BALANCED and UNIVERSAL relation to what is the MIDDLE DISTANCE in/of SPACE; AS E=MC2 IS F=ma, AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!! 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. INDEED, TIME is NECESSARILY possible/potential AND actual IN BALANCE; AS E=MC2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. NOW, consider WHAT IS THE EYE. E=MC2 IS F=MA. Gravity is ELECTROMAGNETISM/energy. (The stars AND PLANETS are POINTS in the night sky.) BALANCE AND completeness go hand in hand. Consider what is outer "space". NOW, consider WHAT necessarily constitutes what is the Sun. E=MC2 IS F=ma. NOW, it ALL CLEARLY makes perfect sense. Think INSTANTANEITY ! TIME DILATION ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS E=MC2 IS F=MA. OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is the Earth. The sky is blue, AND WHAT IS THE EARTH is ALSO BLUE. Gravity IS ELECTROMAGNETISM/energy. Again, the stars AND PLANETS are POINTS in the night sky; AND THEN very carefully consider what is the EXPERIENCE of what is the Sun. E=MC2 IS CLEARLY F=MA. Think about THE EYE !!! Great. NOW, also consider what is the EARTH/ground in BALANCED RELATION to/with WHAT IS THE EYElid. LOOK around. Think INSTANTANEITY !!! ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/energy. E=MC2 IS F=MA !!! It ALL CLEARLY does make perfect sense. Indeed, BALANCE AND completeness go hand in hand. Beautiful. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. THOUGHTS ARE INVISIBLE. It is a very great truth that the ability of thought to DESCRIBE OR reconfigure sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT is similar to sensory experience. Dream experience is/involves true/real QUANTUM GRAVITY. In dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE !!! The EARTH AND THE SUN are E=MC2 AND F=ma IN BALANCE. There is no outsmarting the genius of dreams. Importantly, dream experience GROWS/increases. In dreams, it is you AND other than you are IN BALANCE. GREAT. SO, you don't see any people on what is THEN the BLUE EARTH. Think !!! Gravity IS ELECTROMAGNETISM/energy. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=MC2 IS F=MA !!!

      THE CLEAR AND UNIVERSAL MATHEMATICAL PROOF THAT E=MC2 IS F=MA:
      Gravity IS ELECTROMAGNETISM/energy, AS E=MC2 IS F=MA. The Earth (A PLANET) is a MIDDLE DISTANCE form that is in BALANCED relation to the Sun AND the speed of light (c), AS the stars AND PLANETS are POINTS in the night sky; AS E=mc2 IS F=ma. ACCORDINGLY, gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites; AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 IS F=ma. This NECESSARILY represents, INVOLVES, AND DESCRIBES what is possible/potential AND actual IN BALANCE. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.

SO, time DILATION ULTIMATELY proves (ON BALANCE) that ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=MC2 IS F=MA !!! GREAT !!! BALANCE and completeness go hand in hand. Indeed, it ALL CLEARLY makes perfect sense.
      Gravity IS ELECTROMAGNETISM/ENERGY. A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=MC2 IS F=MA. (The stars AND PLANETS are POINTS in the night sky.) "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Indeed, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY; AS E=mc2 IS F=ma. Accordingly, the rotation of the Moon MATCHES it's revolution.

Gravity AND ELECTROMAGNETISM/energy are linked AND BALANCED opposites, AS E=mc2 IS F=ma; AS ELECTROMAGNETISM/ENERGY IS GRAVITY !!!
      By Frank DiMeglio
      WHY ELECTROMAGNETISM/ENERGY IS UNIFIED AND BALANCED WITH/AS WHAT IS GRAVITY:
      Gravity AND ELECTROMAGNETISM/ENERGY are LINKED AND BALANCED opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Therefore, Einstein's equations and Maxwell's equations are unified (given the addition of a fourth spatial dimension); AS E=mc2 is DIRECTLY and fundamentally derived from F=ma; AS TIME DILATION proves that electromagnetism/ENERGY IS GRAVITY. ACCORDINGLY, Einstein's equations predict that SPACE is expanding OR contracting in and with TIME; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!! (Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.)
      Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, the rotation of the Moon MATCHES it's revolution. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent WITH/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Accordingly, objects fall at the SAME RATE (neglecting air resistance, of course); AS ELECTROMAGNETISM/ENERGY IS GRAVITY.
      Gravity IS ELECTROMAGNETISM/ENERGY. A PHOTON may be placed at the center of what is THE SUN (as A POINT, of course), AS the reduction of SPACE is offset by (or BALANCED with) the speed of light; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. THE SUN purely exemplifies time DILATION. INSTANTANEITY is FUNDAMENTAL. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT !!!
      The stars AND PLANETS are POINTS in the night sky. Let's compare this directly with BOTH a falling object AND the speed of light (c). Great. E=mc2 IS F=ma. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. This NECESSARILY represents, INVOLVES, AND describes what is possible/potential AND actual IN BALANCE. Time DILATION proves that electromagnetism/ENERGY IS GRAVITY, AS E=mc2 is DIRECTLY and fundamentally derived from F=ma. INSTANTANEITY is FUNDAMENTAL to the FULL and proper understanding of physics/physical experience. Ultimately and truly, TIME is possible/potential AND actual IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. The ultimate unification of physics/physical experience combines, BALANCES, AND includes opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT. It ALL makes perfect sense. THINK !!!
      The Earth that undergoes time DILATION IS thus represented (ON BALANCE) as what is A POINT in the night sky, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. (So, notice that the BLUE SKY IS no longer visible. Think.) E=mc2 IS F=ma. It is FULLY proven. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Alas, the INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. I have truly, CLEARLY, AND MATHEMATICALLY unified physics/physical experience. OVERLAY what is THE EYE in BALANCED RELATION to/WITH what is THE EARTH. (Notice the black space of THE EYE, AND the DOME of a person's eye is ALSO visible.) THE EARTH is ALSO blue. Again, E=mc2 IS F=ma. The stars AND PLANETS are POINTS in the night sky. Time dilation proves that E=mc2 is DIRECTLY and fundamentally derived from F=ma, AS electromagnetism/ENERGY IS GRAVITY.

      Because there is no such thing as force! Not in the way that you visualise . What you call FORCE its just Fields that are vibrating . This fields are every where. Matter is just energy entraped in a closed space . This energy cannot be destroyed or created and wants to fill every space of this space evenly . When this energy its reaching 0,5MeV then the electron field start vibrating and imediatly creates a particle thats its called electron. And so on for every single of the known particles with different energies too.
      You try to move this particles then ( an electron lets say ) , at the place in space where this wave move it econters another particle . If this particle is charged then interact with it , and that means that at that 3D space point there is more than just 0,5 MeV. That means that outher fields start to vibrate and so a quark starts to emerge lets say.
      If you can name me a single particle that stay at rest (and not moving) I will admit that I am wrong. Why a particle must allways move? because particles and forces , given that forces derives from the interaction between particles , are just excitations in this Fields , and that its why particles are wave . Because fields move in a wavey form.

      Several people such as yourself have remarked on the incompatibility between the general relativistic view of gravity (bending of space-time) and the quantum view (exchange of force carriers). This is exactly the point - there isn't a unified theory (at least, not one widely accepted let alone verified) that brings both perspectives together. It's almost an article of faith that all forces can be unified, but there is no direct evidence that gravity can be unified with the other 3. Part of the incompatibility between these views is that in general relativity, mass has an effect which "spreads out"; in quantum physics, we only discuss what happens essentially at a single point (or small volume of space more realistically given Heisenberg) when particles interact.

    How long would it take for an electron spiral in to the photon by emitting gravity waves. Sounds like that can be calculated

    • @seanlynch8339
      @seanlynch8339 7 лет назад +9

      That can be calculated in a naive fashion, but would be meaningless, as electrons do not really 'orbit' the nucleus. That is not what the video was talking about.
      time of decay (due to gravity waves for massive bodies) =
      5 (a^4) / 256 * M1 * M2 * (M1 + M2)
      where 'a' is the distance between M1 (mass 1) and M2 (mass 2).
      This will not work for electrons as electrons do not really 'orbit' The video was talking about the electron orbit's decay die to radiating away electromagnetic waves.
      There used to be a model of atoms as little 'solar systems' with electrons in orbit around a central nucleus, like planets in orbit around a sun. This created a paradox that led to the development of quantum mechanics. When a body, like a planet, is in orbit around a much larger body, the planet is constantly accelerating. The planet may be going around the sun at a constant speed, but velocity is a vector with both speed and direction. Since the planet is following an elliptical path, it is constantly changing its direction, even if the speed is the same. We'll leave out gravity waves for now.
      Charged particles, like electrons, emit radiation when they are accelerated. The radiation is in the form of electromagnetic waves. look up the Larmor Formula for more information on how to calculate the power radiated by an accelerated point charge.
      If you picture an atom like a tiny solar system with an electron in orbit around a nucleus you know that the system is stable because the electron's orbit does not spiral down into the nucleus. The 'velocity' of the electron must be 'fast' enough that, even though it feels a strong electric charge attraction to the protons in the nucleus it has enough velocity to maintain 'orbit'. However, a body in orbit is a body that is constantly accelerating, and a constantly accelerating point charge is constantly emitting electromagnetic radiation. The radiation means that energy is leaving the system, and the expected result is that the 'orbit' of the electron would decay and spiral into the nucleus.
      It does not decay. It does not emit radiation (due to its 'orbit'). It is extremely stable. Quantum mechanics was developed to explain the 'orbits' of electrons. the term 'orbit' was kept, but it is not like the orbit of a classical body. It is an energy state that the electron and nucleus system can exist in. The states are discrete, or 'quantized' in that an electron can be in one state or another, but never an in between state. It can be in state 1, 2, 3 but never in state 1.79. When an electron moves between states it either emits or absorbs a photon of the exact wavelength (a measure of a photon's energy) needed to jump the electron from the beginning level to the final level. (this is the origin of emission and absorption lines in spectrum analysis)
      Since the electron is not really in orbit, it does not make sense to calculate the gravity waves generated by its orbit.
      You can find a formula for calculating the time in years for two massive bodies in orbit around each other in equation number 44 of the following paper:
      www.tapir.caltech.edu/~chirata/ph236/2011-12/lec15.pdf
      However, this does not really apply to electrons and a nucleus, because we know that electrons do not orbit the nucleus. If they did, they would radiate and matter all would decay on timescales of seconds. We know matter is pretty stable, so the idea of electrons in orbits is not accurate. It may be something our brains can picture better that quantum wave probabilities, but nature is under no obligation to care about what we humans feel comfortable with being able to picture and understand.

      I'm not using GR or quantum as base, trying to express my thought below.
      Gravity holds things together, so for that at minute level, there has to be non holdable entity, like energy. Energy has properties like harmonic or flow or vibration etc. If energy is not infinite then it may start to wear out eventually at some point in space, because of vibrations, flow etc.
      Gravity property could isolate wearing out and create a particle. Gravity could also cluster these particles so as not to get destroyed by energy, could be due to law of conservation. So gravity could naturally support swarm properties and clustering. It doesn't fully fuse entities due to either 'isolating other energies' property of gravity or it could fuse gravity properties in particles itself and then they don't fuse. Total fusion is energy's property. Effect of gravity may be observable only when two particles interacts, like momentum property, when a particle consists of more smaller particles. Particle purely implies "size" if it does not consist of other particles. Size is space property, implying presence of gravity everywhere in space in some form, similar to luminous eather. Just size property implies sheer presence, dominance and hence slow attraction property at distance, but nonlinear attraction in close proximity.
      Gravity itself could be hunter energy of weakness of other stronger energies.
      This is just a thought without any mathematical base or model. But this could be simulated on computers.
      It also implies bondage for energy and space due to which energies could start to wear out eventually. Different types of particles implies different amounts of wear out energy or presence of different energies.
      Humans have evolved in highly quantized world and see energies only through particles and photons. So we may not detect non quantized energy directly, even our devices are quantized.
      In double slit experiment, when electron passes through both slits, we can say that energy of electron start to wear out due to possible two paths and gravity creates two electrons from wearing out energy which then passes through each slit.

      Take a particule for which when it is at position x, its speed is -x. (Don't ask me how it is possible, it is just for illustration.) So, when the particule is in the negative positions, its speed is toward the origine, and when it is in the positive positions, its speed is also toward the origine, but such a particule will never reach the origine (unless it starts there). It is linked to convergence/divergence of infinite sums.
      So, indeed, it could take an infinite time for gravity to accomplish the described goal, but the "reason" explaining while the electric attraction forbid it in the first place, while being much stronger, would still forbid it, anyhow...

Note that electrons and the components of nuclei are fermions; bosons would be able to spiral all the way in. This doesn't work in gravitationally-bound systems on a macroscopic scale, in which orbiting objects can spiral in with emission of gravitational wave energy limited only by collision of the objects (or in the case of black holes, complete merger).

    Layperson question: Is it possible gravity is a "side effect" of the other three forces? A type of interference pattern generated by the interaction of the other forces? Also, if gravity is quantum, wouldn't it be instantaneous at any distance, like entanglement? Is It?

    • @rodllewellyn
      @rodllewellyn 7 лет назад +1

      No, gravity is not instantaneous (as in Newton's theory). This in fact was how Einstein began his general theory - his special theory implied that no information could be transmitted faster than light (let alone instantaneously), and that includes gravity. If you wiggle a mass, in Newton's theory other masses would immediately feel the change in direction of the force from the wiggled body. In GR, that can't happen, so instead the wiggled body emits gravitational waves - which HAVE now been detected.

    • @jorgepeterbarton
      @jorgepeterbarton 6 лет назад

      But the falling of objects is not the force, the force is the curvature of space-time- so is THAT instantaneous? Surely gravitons would act in space-time warping, not pulling objects together, because GR already gives us the reason why objects are pulled together if space-time is warped.

    • @GlassTopRX7
      @GlassTopRX7 6 лет назад

      The effects of gravity move at the speed of light. So if some how the Sun just vanished we the Earth would continue to orbit the location where the Sun was for another eight minutes and twenty seconds. It's not instantaneous. The fact that there are measurable gravity waves prove that it's not instantaneous. There are also ways to measure the propagation of gravity in a lab.

      - I like you - you seem smart and open minded enough to challenge current paradigms that clearly fail every area of science - people think particle physics is some high grade learning only for boff's - but this shit really dictates our reality - every area of life everyon should get to know some of it - I mean if the standard model of particle physics and it's minion can't tell us more about the nature of subatomic particles then they auto fail as scientists
      - For example what's really occurring in our sun - as standard solar model doesn't even include the weight of neutrino's (do they?) - we even see radio-active nuclear decay rates in laboratories around the world now varying due to the rubbing off effects of neutrino oscillation - this is a bit mind blowing.
      - Anyway point being could neutrinos not be the origin of matter-antimatter asymmetry and the origins of matter itself - I heard it might be a resolve for super-symmetry and higher unification principles correlating to quantum gravity and proton decay.
      - The Cosmic microwave background (CMB) is thermal - electromagnetic radiation - a cosmic sea of energy left over from the primordial universe - and is referred to as relic neutrinos or (CNB) - postulated as the "Dirac Sea" at one stage - electrons, muon and tau neutrinos are the second most abundant sub-atomic particles in the universe other than photons and weigh a minuscule amount far preceding that of an electron
      - Even the Higgs-Boson doesn't have as much significance against the neutrino - while travelling through space, a neutrino apparently continuously flips between different "types" of neutrino, changing the way they interact with matter. This is called neutrino oscillations and thus has an extremely minuscule amount of weight.
      - This is the missing universal mass preceding that of the Higgs-Boson - the masses of other matter particles, generated by coupling to the famous Higgs particle, vary widely - from the electron, about 2,000 times smaller than the mass of a proton, to the top quark, which weighs nearly 200 times more than the mass of a proton. The neutrino mass, however, is at least 10,000,000,000 times smaller than the proton mass hence it is referred to as a WIMP.
      - Most people will have heard of electrons, neutrons and protons - and perhaps even quarks, which make up the latter two. But to me, the neutrino is the most amazing fundamental particle. They are everywhere. About 65 billion neutrinos, produced by nuclear fusion in the Sun, pass through every square centimeter of area on Earth, every second, without doing much of anything.
      - Formed in the first seconds of the so-called big bang, the CNB is a dark, invisible candidate for the seat of electromagnetic phenomena. Like the Cosmic Microwave Background, the CNB can provide a universal rest frame and, at a temperature of 1.95 K⁰, the CNB forms a frictionless superfluid that permeates space.
      - Recent experiments suggest that the electronic neutrino is a tachyon - a tachyonic CNB is also a dark energy candidate; while, at the same time, analogous to cosmology‘s - quintessence‘. (Aether - Quinta Essentia - Prima Materia)
      - Question is could it be really be an Aether candidate and would it not be the best substitute for the cause gravitational fields due density, mass and the electromagnetic field resistance of particles - i.e. generating EG fields (electrogravitics) - are they not much better suited as a gravitational candidate than so-called gravitons?

    • @taariqm-star6162
      @taariqm-star6162 9 лет назад

      May be dark matter has something to do with the creation of gravity. ¨Since the information contained within a region of space depends upon
      the arrangement of objects within that region, moving the objects can
      change the entropy within the region. Verlinde demonstrated that this
      produces an entropic force that acts like gravity. From the basic idea
      of information entropy, one can derive Einstein's equations of general
      relativity exactly.¨ www.forbes.com/sites/briankoberlein/2016/11/08/solution-to-dark-matter-proposes-that-gravity-is-an-illusion/#27d5d1813058

      @einsteinvondaniken 7 лет назад +11

      Not that I'm a physicist or anything, but I think they're wrong about both. I think it's more likely that gravity is an equal and opposite reaction to the effect mass has on space-time. They say time slows down, or drags, on mass. Well that's why matter can't reach the speed of light, right? Because as it accelerates it gains "mass" in the form of velocity, to the point time would slow down and the particles would become too "heavy" (massive) to accelerate any further. Or that's why they say flying around a black hole would cause you to age slower. Or why going faster than light would cause you to travel back in time. So anyways, if mass accelerating through space causes time to slow down, could time slowing down cause mass to accelerate? In other words, the gravity is strongest at the center of mass. So time must be moving slower at the ground than above head. That's why we are constantly being pulled or "accelerated" toward the ground. I know I'm sometimes all over the place and bad at explaining things, but my hypothesis works with everything. If time slows down when you move faster, (atomic clocks on airplanes) and bigger planets have stonger gravity (because more mass) and fat people weigh more (isn't weight really just a measurement of gravity?)... I dunno. I rambled at NASA about this idea, and they gave me a "atta boy, have a sticker" type of response lol so maybe it sounds crazier to others than to me. But in my mind, it seems more correct than following the curve. Because when I'm not moving through space, I'm just sitting here, I'm still accelerating toward the earth. That's got to be a reaction to something, not just a line being followed. Who knows. Whatever.

      I'll just mention one error in your post. You say: "the gravity is strongest at the center of mass". This is false.

On the old times called "eter". This idea was abandoned because nothing was found on vacuum, however no further explanation was given about how wave propagation occur.
      I will put this in math terms:

    it is impressive how the inner constructs of us to represent knowledge that is quite abstract tend to have a pretty diverse latent space for every different speaker. Usually we don't really grasp this because, the cannon content stands out. But if we imagine that concepts are derived from a multiple dimensional space (not speaking of physical dimensions, rather expressive dimensions), although all the dimensions must be compressed into a converged global optimum, the idea of looking to a single formula and expecting it to spit all out, is rather simplistic. We would have far more success if we could explore the latent space of the knowledge, instead of iterating to get always the same convergence at the end. Sometimes is the convergence that fail to compute an important dimension to the outcome. I loved the part that implied that maybe we have to consider something that exists that is not physical, this is so absurd, but yet the latent space revealed by it is huge - basically we are open to some serious refactoring of our theories. I have come to believe that gravity actually is the true bearer of the most fundamental information to form our universe. We would flip the notion that matter would have a feature that is expressed as gravity, and actually all the particles come from gravity.

    • @johnniefujita
      @johnniefujita 4 года назад

      So the gravity would behave like a probability wave, and as probability gets more dense, it would start expressing itself as some particular kind of content in the universe. The universe would be like a strum on a guitar string. Black holes would be the guitarists. which would indeed imply that for the universe to exist it would have to be generated from the tension of the center of a black hole. Which would also explain the rate of the universe expansion being fractal in space.

    Here's a thought experiment I've been playing with: Let's say that space is not really empty but is made up of particles even tinier then the tiniest ones that we can measure and that each of these particles exist within a cubic pattern equidistant from one another all the way from one edge of the universe to the other. Now, lets say that matter appears and pushes or compresses these smaller particles. The particles attempt to push and consolidate the now present matter into the same location. The more that the smaller particles are displaced or compressed together, the greater their density and the harder they push against the matter. Get enough matter consolidated together, the displaced particles become super compressed and super dense creating a super amount of gravity around the object.
    Picture it like a bowling ball that magically appears in the middle of the material that makes up a foam mattress and how tight the foam would be around it, but getting further away, although the foam would still be slightly compressed, it would not be as compressed as it is within the area of the bowling ball. It's probably a stupid thought, but since we don't know what actually causes gravity, guess it's as good as any.

    Energy equals mass times the speed of light squared is Einstein's famous equation E=MC², but why and what process links energy, mass and light together in this way? In this theory E=MC² is an approximation of (E=ˠM˳C²)∞ with energy, mass, light and time dilation all part of one process. Energy ∆E slows the rate that time ∆t flows as a process of continuous creation relative to the energy & momentum of each object or life form. Mass will increase relative to this with the inward force of gravity linked to the outward momentum of light. Therefore both gravitational and electromagnetic force are relative to the inverse square law!

    Force (physics) does not exist physically in the same way that an object with mass, thus making it “not” the initial cause of pushing, pulling, shaping objects, motion, work or being a Vector Quantity (Magnitude + Direction).
    In physics, the word, “Force” as we know it, turns out to be nothing more than an expression to express an idea, like one would use the word “Love” to express one's feelings. But, physics and in mathematics, still use “Force” as thou it were something physical that could enable the initial cause of motion making it counterintuitive.
    Example: Without applying the Energy from within you, choose an object of your choices to push and pull by simply applying “only” the Force or Net Force.
    Meaning that Energy (applied energy) is the origin of motion and not “Force”. Once Energy (E) is applied, it creates what is known as Momentum (p). When this Momentum (object in motion) comes in contact with another object(s), it makes a surface contact that will enable you to push and pull. Example: Ep=ma, Ep=mv and so on. Note: Ep is not to be confused as Kinetic Energy in any way.
    Momentum represents things like work, wave, gravity, light, lightning, tsunami, earthquake, current, electricity, motion, magnetism, etc.
    Without Energy, there is no Momentum. Without Momentum, there is no surface contact on an object(s) to push, pull, work, shaping objects, motion, gravity, etc. Momentum does not and cannot exist without the applied Energy that creates it. Energy and Momentum or “Ep” is the one and only common denominator that links all fundamental forces of nature. Without Ep, all fundamental forces of nature would be inert and non-existence.
    Energy is energy, but it’s when Energy (E) is being applied that creates the Momentum (p) making it the initial cause of motion. Example: Ep.
    By applying the right amount of Energy, nothing is immovable or unstoppable. ~ Guadalupe Guerra

    Dr Lincoln,
    thank you for another great video. I have one perennial issue with this approach to gravity. Am I wrong in thinking that there are really only 3 fundamental FORCES: Strong weak and Electromagnetic each mediated by it’s own gauge boson. When we discuss gravity we are not talking about a FORCE, we are (if I understand relativity at all) talking about the curvature of spacetime due to huge concentrations of matter. Why does this require a gauge boson at all? Surely gravity is so resistant to being combined with the other forces because it’s not a force it’s a distortion.

      +ScienceNinjaDude And how fascinating is that (and I know I’m not telling you anything you don’t know…that is the point of your video after all) because surely a massive object (like the earth) is simply a collection of a huge quantity of subatomic particles. If we reduce the quantity of these particles by half we reduce the force of gravity by (and correct me if I’m wrong ) by 4? times. Reduce by half again and the same effect occurs. Is there a point where gravity completely disappears and is replaced by Quantum Mechanical forces and what exactly happens at that threshold. If we add one more atom at that threshold what is the change. This is fascinating stuff, what a great universe we live in :-)

    I have been looking at a candidate for a unified field theory for a few years. Dr Felix Finster has been working on this for a dozen years. He's a prof of mathematics in Germany studying the mathematical foundations of QFT. I have been impressed with the new ideas that he and his team have been writing about in a dozen papers. If I understand his work, he has found a way to not subtract the infinite terms during renormalization but that these infinities are caused by the standard model being formulated in flat spacetime. He calls it "casual fermion system." I found his work while forming a new model of dark matter. I have a PhD in physics from UC Irvine but I have not found a problem with Finster's work yet. If you could kindly spend 5 minutes googling this material and send me a sentence of why it's wrong I would be grateful. Thank you. Ed Lulofs

    I am mostly a physics hobbyist. Curious but unaccredited. I am kicking around the idea that quarks are tetrahedrons rather than points or spheres. Their orientation (which face contacts another ) forms the strong or weak nuclear force and the ability to carry a charge the electromagnetic force. Matter always has positive mass. Negative mass is an imaginary number like wishful thinking. Mass always has momentum corresponding to density of mass and velocity. Matter having mass also has the property of affection time. The larger the mass, the slower time progresses. The current thinking is that the Higgs Boson is responsible for mass, but the boson is a more complex form than a quark.
    What my basic premise is that quarks have alignments. Spin has to have a axis, even if not the center of mass. Ellipses have two axis. The question is; could gravity be an alignment pointing to mass and could gravity be a vector of momentum. There would be larger factors of momentum in motion / velocity, but the alignment would always point to the largest local mass. The larger the mass, the more offset the alignment toward mass and thereby affect the curvature of mass/momentum vector in a gravity well. No need for a specific force carrier like a graviton. Thanks for even spending the time to read this. I'll keep playing with my 3-D models and diagrams.

    My suggestion proposes that space time is made up of dipole magnetics, which are small particles with randomly distributed magnetic fields. According to this idea, the connections between these particles create an elasticity in space, allowing for the bending and twisting of space time. This elasticity allows for the explanation of the force of gravity through the bending of space, and the creation of magnetic fields from pulsars through the twisting of space time. Additionally, the suggestion compares subatomic particles to air bubbles in a magnet superfluid.

    But to ask a question: what is the 'force' of gravity?
    -GR would imply its not the pulling together of objects....that's due to the flow of time, geodesics in space-time, the nature of speed of light etc.etc.
    -but, it is the 'force' that somehow warps space-time due to mass, right?

  • @IIIllllIIIIlllll

    Probably dumb question, but why do gravitons need to exist, if gravity is simply the warping of space time? Why do particles need to exist for matter to follow the curves of space?

    The page Nexus of Physics has now given the following two writings the thumbs up on their page. ALSO consider this: E=mc2 is DIRECTLY and fundamentally derived from F=ma, AS E=mc2 IS F=ma; AS time DILATION proves that electromagnetism/ENERGY IS GRAVITY.
    THE UNIVERSAL AND MATHEMATICAL PROOF THAT ELECTROMAGNETISM/ENERGY IS GRAVITY:
    Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. E=mc2 is DIRECTLY and fundamentally derived from F=ma. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. SO, gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity AND ELECTROMAGNETISM/ENERGY are linked AND BALANCED opposites, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THE SUN AND THE EARTH are described and represented by BOTH F=ma AND E=mc2. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS ALL of SPACE is NECESSARILY electromagnetic/gravitational (IN BALANCE). Objects fall at the same rate (neglecting air resistance, of course), AS the SPEED OF LIGHT is RELATIVELY CONSTANT AS WELL. ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity IS ELECTROMAGNETISM/ENERGY. In fact, the rotation of THE MOON MATCHES it's revolution; AS gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. So, THE PLANETS (INCLUDING WHAT IS THE EARTH) are not "falling" in what is "curved SPACE" in RELATION to what is THE SUN. This is nonsense. E=mc2 is DIRECTLY AND FUNDAMENTALLY DERIVED FROM F=ma. This truly explains PERPETUAL MOTION. Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black. The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY.

    EINSTEIN NEVER UNDERSTOOD PHILOSOPHY, MATHEMATICS, AND PHYSICS, AS HE HAS BEEN TOTALLY OUTSMARTED BY SIR FRANK MARTIN DIMEGLIO:
    The balance of being AND EXPERIENCE is ESSENTIAL. BALANCE AND completeness go hand in hand.
    THE SELF represents, FORMS, and experiences a COMPREHENSIVE approximation of experience in general by combining conscious and unconscious experience. MOREOVER, the ability of THOUGHT to DESCRIBE OR RECONFIGURE sensory experience is ULTIMATELY dependent upon the extent to which THOUGHT IS SIMILAR TO sensory experience. THOUGHTS ARE INVISIBLE.
    Dream experience is/involves true/real QUANTUM GRAVITY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. MOST IMPORTANTLY, in dreams, BODILY/VISUAL EXPERIENCE is invisible AND VISIBLE IN BALANCE. IMPORTANTLY, dream experience is possible/potential AND actual IN BALANCE. THE EYE is ALSO the body. Dreams improve upon memory AND UNDERSTANDING. Indeed, there is no outsmarting the GENIUS of dreams.
    OVERLAY what is THE EYE in BALANCED RELATION to/with what is THE EARTH. NOW, get a good LOOK at what is the translucent, SEMI-SPHERICAL, QUANTUM GRAVITATIONAL, AND BLUE sky. Excellent. The DOME of a person's EYE is ALSO VISIBLE. THE EARTH IS also BLUE (as water).
    F=ma AND E=mc2 PROVE that, why, and how ELECTROMAGNETISM/ENERGY IS GRAVITY. This NECESSARILY represents, INVOLVES, and describes what is possible/potential AND actual IN BALANCE. SO, it is NECESSARILY a matter of precisely how these equations are understood in a BALANCED, EXTENSIVE, AND INTEGRATED fashion in RELATION to/with WHAT IS THOUGHT. The INTEGRATED EXTENSIVENESS of THOUGHT (AND description) is improved in the truly superior mind. E=mc2 is DIRECTLY and fundamentally derived from F=ma.
    Very importantly, outer "space" involves full inertia; AND it is fully invisible AND black.
    The stars AND PLANETS are POINTS in the night sky. A PHOTON may be placed at the center of THE SUN (as A POINT, of course), as the reduction of SPACE is offset by (or BALANCED with) the SPEED OF LIGHT; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Get a good LOOK at what is THE EYE. POINTS are points. Gravity IS ELECTROMAGNETISM/ENERGY. ELECTROMAGNETISM/ENERGY IS GRAVITY. GRAVITATIONAL force/ENERGY IS proportional to (or BALANCED with/as) inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY involves BALANCED inertia/INERTIAL RESISTANCE consistent with/as what is BALANCED electromagnetic/gravitational force/ENERGY, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. "Mass"/ENERGY IS GRAVITY. ELECTROMAGNETISM/ENERGY IS GRAVITY. Energy has/involves GRAVITY, AND ENERGY has/involves inertia/INERTIAL RESISTANCE. F=ma AND E=mc2 PROVE that ELECTROMAGNETISM/ENERGY IS GRAVITY, AS ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. GREAT.
    The stars AND PLANETS are POINTS in the night sky. OPEN your EYES. NOW, LOOK at what is the FLAT, SETTING, AND ORANGE SUN (with the SPACE around it THEN going invisible AND VISIBLE IN BALANCE). This ORANGE SUN manifests or forms at what is EYE LEVEL/BODY HEIGHT as well. This ORANGE SUN is manifest ON BALANCE as what is NECESSARILY the BODILY/VISUAL EXPERIENCE of THE EARTH/LAVA. The viscosity of LAVA IS BETWEEN what is manifest as WATER AND THE EARTH/GROUND. ALL of SPACE is NECESSARILY electromagnetic/gravitational IN BALANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. F=ma AND E=mc2 do provide absolute, BALANCED, THEORETICAL, and CLEAR proof that ELECTROMAGNETISM/ENERGY IS GRAVITY.
    Gravity/acceleration involves BALANCED inertia/INERTIAL RESISTANCE, AS ELECTROMAGNETISM/ENERGY IS GRAVITY. THEREFORE, the rotation of THE MOON MATCHES it's revolution. MOREOVER, a given PLANET (INCLUDING WHAT IS THE EARTH) sweeps out equal areas in equal times; AND this is THEN consistent with/as what is F=ma, E=mc2, AND what is PERPETUAL MOTION; AS ELECTROMAGNETISM/ENERGY IS GRAVITY. It ALL makes perfect sense. BALANCE AND completeness go hand in hand.
    THE PLANETS (INCLUDING WHAT IS THE EARTH) are NOT "falling" in what is "curved SPACE". In fact, this is nonsense. It is PROVEN.

    Einstein and others seem to be suggesting that gravity does not exist as a force (and therefore has no force carrying Graviton particle) like the forces we know but rather gravity as a force is an illusion caused by mass (or energy as per e=mc2) bending spacetime which is affecting the paths of real particles and photons. This effect is what we, as humans, interpret as gravity. Saying all that I still hear physicists talk about the force of gravity so which is it? Is it a real force or is it a virtual force?

      This is a great question. If gravity is just the effect of curved spacetime, then why would we expect there to be a force carrying particle at all?

    I have a lot of thoughts and will post some some questions but I have to ask this one now. From the plank size with all of that incredible space to electrons, are there particles in between them? That is one incredible gap for something not to be there. Because of quantam mechanics and the weird stuff going on there, is there any hints of any kind of what is going on in that space?

    Don, in your presentation, you mention that no one understands why the speed of light is what it is. But, couldn't one go to Maxwell's equations, and look at the resistances to changes in electric fields and magnetic fields, and from there determine why the speed of light is what it is? I believe that this has been done, by Maxwell and others. Now, why those resistances are what they are may truly be unknown...something in the nature of spacetime itself, perhaps. Thanks for the great presentations!

    IIRC, one problem with quantum gravity is that as predicted by general relativity, gravity effects how time moves. But for quantum mechanics, time must be the same everywhere.
