      People sometimes develop tics like that when they are working around a serious stuttering problem. I don't know if that's his case. (Rowan Atkinson has this weird way of pronouncing the letter "B" for that reason, and he uses it to great comic effect!) Could be anything really. (He might have a duck in his pocket :P )

    Excellent experiments with advanced technologies, self-test by comparison with previous reports, and wether or not we know anything new about abstract angles of approach to fundamental concepts, there's more precisely refined scientific methodology to apply to the general industrial culture.
    The most significant observation in these related presentations, is the picture perception of Physics and Geometry in the "close-up " of the movie about black hole singularity, and how it has no "sides", all of the shadow is visible, because it's WYSIWYG all-ways all-at-once forever Hologram, and it is the best representation of a oneness-connection, symbolic of omnidirectional-dimensional Origin of Superspin Modulation.
    _____
    The slow-fast-slow ticking (resonances) clock follows a hot-cold-reheat arc of "convection" or the freeze emission of time duration timing modulation, apparent floation, pure relative motion mathematical reciprocal positioning formulae of non-synchronized inflation +/-, and therefore excluded because expanded and slowed reference frequencies etc of the "wave-particle" relative-proportionate uncertainty kind, in the universal wave-package probability, clock "gearing", relationship proportioning.
    First I've heard this presentation of Einstein's awareness of straight-line time.., which is equivalent to flat-space ground state boundary of here-now-forever omnidirectional-dimensional Origin, of Superspin self-defining cause-effect Modulation, the indeterminate limit of potential possibilities difference distribution in this unitary absolute zero-infinity reference frame.., this Thought Experiment was well demonstrated.
    The gravity curvature shaping Spacetime due to probability resonance imaging function, here-now cause-effect of time duration timing modulation, is logarithmic synchronization quantum orbital in resonance-chemistry, projected onto 2D from 0-1D omnidirectional-dimensional Origin of Superspin Modulation as an imagined (i-reflection/differentiation of pure relative motion ratio rate) cone, in which the Quantum Number sequence cause-effect of resonances 0-1-2-3-4-...nD according to the degree of accuracy logarithmic numberness bases in e-Pi-i functional continuous creation connection Principle allow.., for-of QM-TIMESPACE In-form-ation .
    It's perceived reality to limit possibilities to practical physical probabilities and use Number identities to manipulate Actuality using experience and intuition, but if "all is relative" then "everything is probabilisticly connected" by-default, ..e-Pi-i interference positioning resonance.
    A Spacetime oriented curriculum has to be re-drawn in temporal terminology where "parallel lines in flat-space, meet at infinity", is equivalent to Entangled here-now-forever Universal Coexistence of QM-TIMESPACE.
    It depends on the construction of a personal Memory Palace, wether by careful intent or coincidental default, naturally.
    So the cones of time duration timing re-modulation interference positioning integration.., all are static drawings of superimposed metastable resonances, spaced in twice exploded multi-phase-locked states of a graphical presentation of the pure relative motion e-Pi-i function.., which is why Bergson's Intuitive observation and Einsteinian Theoretical Curvature-s are mathematically corresponding in probability positioning alignment with Euler's Intuitions. (Navigational symbology of logarithmic condensate probability mapping, ..of course)
    "Probing" the quantized gravity turbulence in/of the Universe is equivalent to reading the results of everything all-at-once forever, Singularity Conception, the "annealing" Calculations of Superspin Superposition-point Singularity.
    Ie The big Quantum Computer in the sky and focused at the LIGO detector movie of the .dt instant-interval Eternity-now.
    "Wormhole" => fractal scaling of invariant coherent cohesion objectives/Bose-Einstein Condensate, in pulsed resonances of e-Pi-i interference positioning.., make traveling at constant velocities "straight" through flat-space = .dt general sum-of-all-histories Time, so accelerating+/- is curving the metastable resonances curvature.., Wormhole Quantum Jumping, by "dragging the Inertial frame".., corresponding to Inflation-Modulation+/-..

    Kip, I hope you're reading this, or someone that works with you is. There's a misconception about how LIGO works that's being perpetuated here, which is that the mirrors move. The mirrors don't move, the "amount of space" between them changes. There is an easy thought experiment to prove this: imagine one of the mirrors in LIGO being reflective on both side and contruct another LIGO on its other side, if the mirror moved it would be recorded as moving one way by the first LIGO and the opposite way by the second LIGO, this is not possible, so the mirrors don't actually move, rather the amount of "spacetime" between then changes. Another way to see it is if the mirrors move then how far does the mirror at the far end of the second LIGO move, if the mirrors move then the far one moves twice as far as the middle mirror, and if you keep on building more and more LIGOs in a long line pretty soon those movements would add up, but that can't be either, imagine forming a gigantic circle of back-to-back LIGOs around a GW source, if the mirrors actually moved then from your perspective at one point on this circle, the mirrors diametrically opposite you should be colliding, but by symmetry arguments that can't happen (or collisions would also be happening at your location too), so again the mirrors can't actually be moving, instead the "amount of spacetime" between them changes.
    I believe this can be mathematically concluded from the vacuum field equation
    R[u,v] + 1/2 R g[u,v] == 0
    because the Ricci tensor measures the change in spacetime volume and this says the change is zero so spacetime volume stays constant, which I interpret to mean that as a GW passes by in the Z direction space in the X direction gets squeezed into the Y direction, and vise versa, but the total volume stays constant. Except for the "+ 1/2 R g[u,v]" part which I don't understand yet. Perhaps you can help out.
    Thanks,
    Peter A Lawrence, San Jose, CA.

    Someone please check this: I've read about the holographic universe hypothesis, which is based on the fact that all information in a given 3D space can be coded on its surface. But if the whole map of a 3D phenomenon like 2 black holes colliding is contained in the gravity waves, that's 3D information contained in a single dimension, right? The linear dimension between the event and the detector? Imagine - there could be holographic 3D videos on a single 2d film that way.

  • @onemediuminmotion

    Electrons, like atoms, and black holes, and the universe as a whole, are horn toroidal fluid vortices (hence "point-particles") in/of the single, scale-uniform 'super-fluid' medium (I call it the SUM, a.k.a. "space-time") whose self-relative motion (a.k.a. "acceleration"; "momentum"; "push") as vortices and waves, comprises the evolving (hence "time") structure of the universe and all of its content "physical objects". Therefore we can say that the "material universe" is 'pure motion' (primarily point-radial in trajectory). The Einsteinian "time dilation/ length contraction" principle applies to the SUM itself, meaning that its self-relative motion ("acceleration" as 'motion relative to itself over time') is the mechanism by which the otherwise absolutely homogenous SUM 'self-differentiates' into the structural diversity of the observable universe, including our own bodies.
    Also, therefore, not only do massive objects "curve spacetime", massive objects ARE "curved spacetime". The inflow of the SUM equals the point-radial outflow "expansion" of the SUM compression wavefront that is the surface of the mass-object (e.g. the Earth). Ergo the "gravitational (and smaller scale) field(s)". Since SUM fluid vortices, and every complex manifold thereof, including ourselves, constitute 'I/O devices' (inflow/outflow; input/output; positive/negative; "yin/yang"; etc.), we can say that the physical universe is comprised by an otherwise, absolutely continuous SUM "simulating" (by means of its self-differentiating, self-relative motion) a "discrete particle" - based "material universe" as "a universal self-organizing network of distributed I/O devices" which are manifested in terms of their inter-communication by means of the specific sequence of SUM 'vibrational acceleration waves' traveling at the "constant, finite, but asymptotic limit for all mass-objects" speed of light which they emit and absorb. We "human beings" are momentum routers ("pushers" of "things") in that network. In order for there to be a "push", there must be a "something else" to "push against". "Yin/Yang". Consider that every "sensation" - i.e. that you are "conscious" of - is comprised of a "push" (or vibrational series of "pushes") at some scale, at some amplitude, in some 'direction', as a "transfer of momentum"; a displacement of a mass object from its otherwise geodesic path. So the "material universe" is apparently a self-configuring momentum-routing circuit /network. "Consciousness" is 'a self-configuring momentum waveform' in/of the SUM.
    P.S. "Dark matter" is the SUM itself concentrated around its "material" vortices, and "dark energy" is its larger-scale flow.
    th-cam.com/video/MmG2ah5Df4g/w-d-xo.html 0:22/11:57 They are being carried along by the outwardly expanding flow of the SUM (scale-uniform medium) itself from its horn toroidal fluid vortexual architecture "output". They are not, themselves "accelerating" (undergoing "proper acceleration") by means of an 'on-board' power supply. Thus, in this case, they are not moving "through space over time", they are moving "with space over time". Light waves are the universal 'CPU clock ticks' of 'time'. They make up the 'Cartesian coordinate system' of the 'space-time epic' in which we are taking place. ...
    Call the Y axis "time", and the X axis "space". Let your eye be at 0 looking in the positive Y direction, and let any other detector be placed anywhere else along the X axis. The photon (or physical increment of "time") is propagating toward your eye, or other detector, as a spread-out 'shock wave' front, and collapsing point radially toward its detector, only being "detected" when the momentum (acceleration) pulse it is transferring through the SUM (scale-uniform medium, or "space-time") literally from its horn toroidal 'point' of origin is transferred to its corresponding destination point of detection.
    The universe might be described as a 'self-calculating quantum computer'.

      11 years passing provokes all the more curiosity over what has happened. There is a later generation of LIGO, and at least one youtube video with something about it. I just checked the LIGO site www.advancedligo.mit.edu/
      As of today, January 15, 2016, no gravitational waves have ever been reported.
      I don't see any reason why there might not be gravitational waves even under Newtonian gravity, so even for skeptics of General Relativity, which I am not, there is no particular reason to doubt their existence. That doesn't mean there are any large enough or close enough to detect.

      "Gravitational waves cannot exist in the Newtonian theory of gravitation, in which physical interactions propagate at infinite speed." - Wikipedia
      Newton contribution to understanding gravity is that it is universal. The same 'force' that acts on an apple on Earth is the same 'force' acting on all other objects in the universe. Newton did not know what caused or made this force.

    • @kennethflorek8532
      @kennethflorek8532 8 ปีที่แล้ว

      Agimaso Schandir If so, then LIGO sees something other than gravitational waves. According to the description, LIGO uses two lengths (using lasers) at right angles to see if length has changed as a gravitational wave goes by. Newton's equation has the force of gravity differing with distance. Therefore two points at different distances from a gravity source experience a different force, and there is a net force between these points. Therefore all objects are further stretched or further shrunk when a source of gravity moves. Therefore LIGO sees this. I am not saying Newton ever thought this.
      It is a bit much to claim that the Newtonian force due to gravity, or any other force Newton mentioned, is required to propagate at infinite speed, just because Newton didn't account for any speed. Newton did not account for a lot of things, and this was one of his strengths. Every physics demonstration to this day tries to neglect as many things as possible that will still give accurate results; and they are following Newton in this, whether they know it or not. It is very fortunate that this works, when it does, because we would not have any derivations at all were it not for this. However, I don't doubt that Newton thought privately, but did not say, that gravitation was not in need of propagation, but was present due to the hand of God. It would be as if to say the existence of matter needed to be accounted for, which he did not do either.
      While it is true Newton did not know what gravity was, neither did Newton know what matter was. But neither do we today. And there is no prospect whatsoever that we ever will. Newton claimed to know some things about gravity. We have a working knowledge of things, which expands, and that is all we can ever have.

    Newtown predicted gravitational deflection of sunlight as well. Kip doesn't mention that because he knows as well as I do that the audience is already aware of it. And Kip also fails to mention the measurements of bent sunlight in Sobral in 1919, which were closer to Newton's predictions than Einstein's. But of course Kip knows that his audience is already aware of that. Doesn't he? And Kip also neglects to bring to the attention of the audience that the 1919 Principe results were found to be faulted in about 1930, and then only tenuously rehabilitated in the wake of World War 2.
    But then, he is fully apprised of the fact that every member of the audience is totally aware of that. . .

    My hypothesis that Dark Matter is not a WIMP, but maybe is a deformation of space-time by which the curvature of space-time ALONE is the cause of the gravitational effect. Gravity is the consequence of the curvature of space-time. It may be possible that the structure of space-time itself could be warped without the presence of mass. Space-time has been shown to react like a fabric by warping, twisting, and propagating independent of mass. These properties have been proven with observations of gravitational lensing, frame dragging, and now gravitational waves. Fabrics can be stretched, pressured, and/or heated to the point of deformation. Such extreme conditions were all present during inflation, so it is plausible that space-time’s elastic nature could have hit its yield point and permanently deformed. Therefore, if gravity is the consequence of the warping of space-time, and fabrics can be permanently deformed, then a deformation could create a gravitational effect independent of mass. Thus, the unidentified dark "matter" that seems to be so elusive to modern science may not be matter at all but merely warped deformities causing gravitational effects. DM could be a microscopic black hole with no mass at the center...
    Prediction: Spacetime's elastic property hits a yield point, so only that part of geodesic's "stretch marks" would remain after inflation stopped. These steep gravitational wells would not follow the inverse square law. I am looking for Theorists or Experimentalists to help me develop ways to test this hypothesis. Is there a way observationally to test it’s gravity does not follow the inverse square law?

    In this parabolic trajectory Professor did not mention that kinetic energy of apple, drag of G force, and air friction created geometry of apple's parabola. Time is always involved. Time on the beginning of parabola (slower time), and time on highest point (fastest time) on parabola has nothing to do with shape of parabola. In this case slower time , and faster time do not exist on this parabola, simply because in nature does not exist slower, and faster time... Parabola is significantly bent. So if time would play roll in this parabolic curvature, time difference between "slower time", and "faster time" must have significant "length", and this is not the case here. SPACE CANOT BE WORPED. TIME CANOT BE WORPED. SPACE IS NOT FLAT. Photons are material particles wich could be influenced or warped by Sun's gravitational force, this does not mean that space is warped, and so on.

    • @SMILJANable

      Time does not run so there is no faster or slower Time. There is no Einsteinen world! We know in what kinda world we live. Time does EXIST with its natural properties anywhere where is the Space. Time does allow existence of the Universe. Without time will be no Universe. Of course we can experience Time, or not to be consciences about time, specifically when we sleep.Time can't be measured with a clock. Why? There is no way that we can "hook" in Time with our device called clock. The clock is our creation wich can't be somehow tuned into Time. Time as a natural phenomena is not what is the clock. Amusingly most of the Professors in the field of Physics do mix Time and clock including Einstein. But Time does allowed us to have working clock in Time, so we can orient ourself in Space and Time. Time can "take" anything anywhere in the Space or anything synchronized in infinite number of locations in space .This makes Time absolute not relative. Simply Time is "medium" which possesses double infinite capacity. It is "spread" through space infinitely, and can "take" infinitely fast number of infinite events.Time does not allow limitations. This is beauty of Time... Einstein did not understood this. According to Einstein time is relative wich means that time in different points in space is different and also according to EinsteinTime stops when object riches speed of light. Wrong again... Also Time is not revolving around us, or Time does not exist because of us.
      We have intelligence good enough to conclude, or we feel thanks to our conscience that Time does exist. During our existence we are simply "submersed" in Space and Time. Also Time and Space are two different entities. For Einstein Time and Space is the same and he did named Tame and Space Timespace. This is wrong... He did created absolute mess with his statements in so called modern Physics and mess was a politically planed, so Masses would not get proper education. Plan is to kip real science behind closed doors. We can't defy Time in relation to our self because time existed bifore us, during our life and after us.

    The theory states that if an observer measures a photon as he's moving away from it, time has to make up for the distance the photon travels.
    This is WRONG!
    The photon is still traveling at C. It just creates the illusion to the observer that the photon is traveling at a different speed relative to his position.
    If I drive my car at 150mph, passing another car driving at 30mph, I will measure that car moving at 120mph away from my position (backwards)
    But that car is actually still just moving at 30mph.
    The speed you measure any object traveling is relative to your own position but it does not change the actual speed of the object itself.
    Therefore, time remains unchanged to both observer and object.
    Here are the facts:
    1) Time is not a force of nature which consists of matter or energy. Therefore nothing can interact with it. Not even gravity or velocity.
    2) Time is a concept created by mankind to calculate speeds & locations in space and schedule events.
    3) Time can't be distorted, slowed down or speed up. You can't age slower or faster or travel to the future or the past.

      +Thrillseeker303 You have made a rather large blunder. Yes, you will measure the car moving 120mph away from you while in your car, but if you were not moving relative to the road, you would measure the car to be moving at 30mph. Both of these speeds are simply relative to your velocity in space (neither one is the only correct speed). If that didn't make sense, think about being at the center of our galaxy. Now you would measure the car travelling at 140 miles per second (roughly). This is also correct, as long as you clarify from what reference frame you are measuring.
      There is no such thing as objective position, speed, or acceleration. Those properties can only be described with respect to another position, speed and acceleration (subjective).
      Your facts are anything but that. They simply prove how little you've read on the subject of space and time. Not worth a proper response until you stop making shitty youtube comments and educate yourself.

      +Leo Mckee-Reid You've just proved that speed is relative. And that there is no absolute speed for any object in the universe.
      Then how could speed affect time if it's relative to whoever measures it?
      I know this must sound crazy to you but I know for a FACT Einstein has made a huge error in his general theory of relativity.
      Time cannot slow down or speed up and I will not rest until I can prove it.
      You cannot treat time as a fourth dimension which forces can interact with. Forces can only interact with matter or energy.
      And since time is neither, NOTHING can interact with it. Period.
      To say your body would age less quickly because gravity interacts with time is idiotic. Your body is made up of matter. Space and time are non existent. They are simply tools to measure the position of objects which consist of matter.
      Einstein said that the product of acceleration is indistinguishable from gravity which is true even though he also knew gravity and acceleration are not the same.
      But acceleration and velocity are not the same either.
      Acceleration is gradually speeding up from a stationary position to any constant speed.
      Velocity is a constant speed. Acceleration creates a G-force. Constant speed does not.
      Imagine you leave Earth in a spaceship.
      As you lift off, the ship speeds up (acceleration).
      The gravity of the Earth combined with the acceleration will cause you to feel backwards pressure (G force).
      The G force would gradually disappear as you leave the gravitational pull of the Earth and reach a constant speed.
      In vacuum space, as you travel at a constant speed without being affected by any gravitational field, you would not feel any pressure anymore. You could float freely within the fast moving spaceship without being aware of the speed at which you're going.
      Even though your spaceship may be traveling at the speed of light. There would be no G-force whatsoever!
      This would also apply to light as it travels at a constant speed and never accelerates.
      If two spaceships traveling at lightspeed pass each other in opposite directions.
      Both observers would measure Each other's speed as twice the speed of light.
      But since nothing can travel faster than light, the observer would think that time has to make up for the distance.
      So if you make time go half as fast, your effectively force your calculation to be correct.
      But the observer's point of view on the velocity of the other ship has no effect on the real speed or time of the ship.
      Both ships are still traveling at C and time is unaffected for both ships.
      And I want to add. You may think I'm stupid for not believing a theory which is generally accepted.
      But from my point of view, I think you're just as stupid to fall for this mathematical illusion.
      You just don't seem to see the gaping flaws in the theory.

      Allow me to address what I think is your key obstacle in understanding special relativity. Nearing the end of you long response, you said this:
      "But the observer's point of view on the velocity of the other ship has no effect on the real speed or time of the ship."
      Now, what do you mean by REAL speed of REAL time? The entire point of this heavily proven theory (through an incredible amount of evidence) is that REAL speed is not a property of the universe; it is only a relative quality, same for time.
      If you "know for a FACT Einstein has made a huge error", then you must have done the math or conducted some impressive experiment that disproves arguably the greatest theory (and most studied by mathematicians and physicists all over the world) in the last 110 years.
      If you haven't worked out the math, and know exactly what's wrong, or haven't conducted an experiment, then ask yourself this: Why do I, someone with relatively limited knowledge in physics, think with 100% certainty (and nothing but a poorly worded thought experiment) that I've disproved a theory that the greatest minds of the last century have been unable to see?
      I'm not saying you couldn't be right, but just look at what evidence you have vs the enormous claim you are making that goes against over 40 years of incredibly accurate experimental verification.
      Just read about experiments that prove the existence of time dilation (there are quite a lot), and only respond if it's a link to your experiment, your "corrected" equations, or anything that's not sloppy, C- undergraduate level understanding.

Regarding the atomic clock experiment in the airplane. How could anyone even consider a difference of 40 billionths of a second "proof" that time itself can slow down???
      What about the other variables to take into account when you do an experiment like this?
      The environment on the plane may bring certain forces which could interact with the atomic frequency of the equipment. Electromagnetism, static electricity, heat, cold, air pressure, G-Force, vibrations,... all of which may affect the outcome of the atomic clock. We don't even know the behavior of particles down at the quantum level when these forces are applied.
      So how can we assume that it's time itself which is slowing down instead of the equipment being impaired by a force we have overlooked.
      This experiment should not be considered undeniable proof that time itself can slow down.

However, it turns out that the laws of electromagnetism DO NOT follow this rule. If two observers moving with respect to each other watch a fast moving electron, u' IS NOT equal to u - v.

The speed of light (relative to the observer) does vary with the speed of the light source, as predicted by Newton's emission theory of light and contrary to what Einstein postulated in 1905. This is evident from the following quotes:
    www.philoscience.unibe.ch/documents/kursarchiv/SS07/Norton.pdf
    "These efforts were long misled by an exaggeration of the importance of one experiment, the Michelson-Morley experiment, even though Einstein later had trouble recalling if he even knew of the experiment prior to his 1905 paper. This one experiment, in isolation, has little force. Its null result happened to be fully compatible with Newton's own emission theory of light. Located in the context of late 19th century electrodynamics when ether-based, wave theories of light predominated, however, it presented a serious problem that exercised the greatest theoretician of the day."
    philsci-archive.pitt.edu/1743/2/Norton.pdf
    "In addition to his work as editor of the Einstein papers in finding source material, Stachel assembled the many small clues that reveal Einstein's serious consideration of an emission theory of light; and he gave us the crucial insight that Einstein regarded the Michelson-Morley experiment as evidence for the principle of relativity, whereas later writers almost universally use it as support for the light postulate of special relativity. Even today, this point needs emphasis. The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE."

    "Relativity and Its Roots" by Banesh Hoffmann, p.92: "There are various remarks to be made about this second principle. For instance, if it is so obvious, how could it turn out to be part of a revolution - especially when the first principle is also a natural one? Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether. If it was so obvious, though, why did he need to state it as a principle? Because, having taken from the idea of light waves in the ether the one aspect that he needed, he declared early in his paper, to quote his own words, that "the introduction of a 'luminiferous ether' will prove to be superfluous."
    www.amazon.com/QED-Strange-Theory-Light-Matter/dp/0691024170
    Richard Feynman, "QED: The strange theory of light and matter", p. 15: "I want to emphasize that light comes in this form - particles. It is very important to know that light behaves like particles, especially for those of you who have gone to school, where you probably learned something about light behaving like waves. I'm telling you the way it does behave - like particles. You might say that it's just the photomultiplier that detects light as particles, but no, every instrument that has been designed to be sensitive enough to detect weak light has always ended up discovering the same thing: light is made of particles."

      Jason Williford Is that really so hard to understand? I am saying using an apple or two or three apples to demonstrate gravity is absolutely stupid and disrespecting food. I saw similar demo in MIT. Can't believe that elite universities of the world fail humanity and so focused on science that they forget simple thins. Millions of people dream of eating a single apple. I hope you get it now.
