The Absurdity of Detecting Gravitational Waves

    A lot of videos have covered the general overview of the discovery of gravitational waves, what they are, the history of the search, when they were found but I wanted to delve into the absurd science that made the detection possible.
    When scientists want one megawatt of laser power, it's not just for fun (though I'm sure it's that too), it's because the fluctuations in the number of photons is proportional to their square root, making more powerful beams less noisy (as a fraction of their total). The smoothest mirrors were created not for aesthetic joy but because when you're trying to measure wiggles that are a fraction the width of a proton, a rough mirror surface simply won't do.

    See, the absurdity is the actual theory that gravity per relativity. It is incorrect and science just needs to accept this. Why? First, if gravity is the distortion or space-time as proposed by modern theory, it would occur in a 3D plane. Think of a sphere sitting in the middle of a jello mold. The mass displaces the jello causing a geometric distortion inward and all around the sphere. Ok, good to go right? No. Now add a rotational velocity around its center. Then add a orbit around a larger object occupying the same jello mold. Granted any force portrayed would be experienced between a relative body m2 and a large body m1. But here is the problem. Once that sphere is in rotation around that primary mass what happens to the jello mold? Think of a bullet being shot into water. As it progresses through the medium it ripples out perpendicular to motion. A gap is created where the mass displacement occurs and then the water fills that gap, creating sympathetic ripples. The bullet progresses further, it "breaks" the water as it moves, causing an initial ripple head.
    So why do we not see this as the Earth is moving through space? Why do we not see gravitational ripples occurring as we transit perpendicular to our motion? How come there is not reaction from space as the gravitational gap is filled as Earth moves out of a "curved space" coordinate? How come there is no action as Earth produces a new distortion when orbiting as it enters new space?
    See, this is a huge discrepancy with relativity. Gravity in itself cannot violate Newtons 3rd law. So if a mass is moving through space, space is not moving with the mass. This is known because an objects motion is a relative plane. Which means that the gravitational field (curved space) is a process and as the Earth moves this process is repeated over and over. It distorts space, space fills the gap, the mass distorts new space. Even with a small gravitational field this would cause noticeable reactions. Oscillation patterns would be constant and detectable. Not only that, due to the mass of the gas giants and the sun, the transitory oscillation patterns that move perpendicular to them would of destroyed us a long time ago. Therefore, gravity is not a distortion of space=time. In Essence Spacetime is a myth and really doesnt exist.
    So what is gravity and why do our mathematics work? Our measurement and observation of Gravity is not incorrect. Just the theory of how it is created as an effect. As we have tested it, and many others. Gravity is the product of a process. Think for a moment of how pendulums synchronize. The reason is that the pendulums have an equilibrium generated between them. Their masses are similar or they have lengths that are harmonic. This means that they will resonate within a local time reference frame in relation to the primary local time reference frame (Earth). This produces a large resonance between the pendulums and the Earth. Each atom in your body has a local time reference plane. Together, they form an organism which has an overall oscillation. This oscillation is in tune with the primary local time reference plane (Earth). In a sense it is similar to domains of a magnet. Although, this tuning of mass (matter) to local reference plains causes the atoms (dielectric mediums) to align with the primary body. Although subtle, the force is there and we call it gravity. So in essence we can call gravity a dielectric acceleration towards a point of centripetal convergence, which stops when the centrifugal divergence potential is reached. (The electromagnet forces interact in repulsion) The actual explanation is a little more complex. Although if someone is interested, feel free to comment or message me.

    when talking about the uncertainty introduced by quantum mechanics (Heisenberg uncertainty etc.), its explained that it is reduced by forcing on measuring only one thing, namely the distance one arm is stretched compared to the other, thus cramming all the uncertainty into the tho other thing/ measurement which they are not measuring. what is this irrelevant thing with the high uncertainty (the other side of the Heisenberg coin, if you like, to distance)?? is it momentum?

    Wow. Seriously? Why do people believe this bs. The detector is made of atomic particles. Anywhere and everywhere along the detector, it’s atoms are being bombarded by radiation/fast moving particles. How sane are you if you believe that such a massive amount of interference will allow the accurate measurement of a distance of half a proton. Sobering thought for you... Gravitational waves don’t exist. Our understanding of the force between objects is flawed. We can mathematically describe what is happening, but we have know clue why it’s happening.

    I have some doubts about reliability of their results and their scientific methods for the measurements of gravitational waves. How do they correct for the following:
    1. The expansion and contraction of the tube the laser travels in. I know the Eiffel tower expands and contracts by 5 inches each day due to heating and cooling of the metal.
    2. Micro earth quakes that happen all of the time have compression waves that would move the mirrors out of position.
    3. The thermal expansion and contraction of the surface of the mirror they reflect the laser off of.
    4. Variations in the density of the air the laser travels through would cause the light to bend and change the path length.
    5. Expansion and contraction of the bedrock the lasers are mounted on could cause issues with the distance changing.
    6. At these minute distances they are trying to measure even the gravitational pull of the moon as the earth rotates could affect the distances.

    Wouldn't this prove dark matter or something similar to it, because wouldn't gravitational waves need a medium to travel through space. Gravity cant pull on nothing, so its alleged 'waves' would have to manifest through some form of phenomenon that can react to matter andor space-time/other medium. That would require some phenomenon in the vacuum of space.

    They detected something was it gravity there is no answer because no gravitons where found, that is the only way to prove gravity has a particle carrier like a photon does and therefore even has waves.
    gravity could be quantum molecular electromagnetism nothing more and as a theory could be nothing more than a way to describe the warping and bending of space due to matter.
    In my view gravity does not exist and before people tell me to jump off a building that does not mean gravity exists, we once have thought many things to be true that are later proved false, on a molecular level my buoyancy is of course less than the atmosphere hence I might drop, whereas a helium balloon weighs less and of course floats.
    Considering G has been elusive and unsolvable for all forms of science to date I concluded G is nothing more than a description of the curvature of time and space and not a force carrier.

    at 4:21, he says: "the variation deltaN in the number of photons that hit the mirror at any instant is proportional to sqrt(N), what this means is that the more photons you have, the SMALLER the uncertainty gets, which is why they use 1 MW laser". I'm assuming deltaN is the photon noise. Do I understand correctly that the uncertainty is NOT deltaN (deltaN = sqrt(N) grows with N), but what the LIGO people want is a very high signal to noise ratio S/N = N/sqrt(N), which is why you need a high N ? thanks for your answer.
