    What is gravity? We’ve experienced it our whole lives, yet typically don’t question it.
    Isaac Newton described well the processes of how gravity works, without knowing
    or speculating about the actual cause of gravity.

    There were definitely quite a few questions that haven’t been adequately answered.
    Does gravity travel? That it takes time to get from one point to another, the way light
    is said to? If so, how fast? At the same velocity? possibly faster or slower? or what
    if the influence of gravity is instantaneous?

    Of course, the velocity of light is allegedly 186,282 miles per second. Since light is said to take
    time to illuminate or reflect from objects to reach our eyes, when we observe anything
    visually, we allegedly view things as they appeared in the past.

    Here is another question. If the sun were to suddenly disappear, would the earth leave
    its orbit immediately, and take off in that one direction into somewhat of a straight line?
    or would the earth stay in orbit for about the next eight minutes, which is allegedly how
    much time it takes the sunlight to travel to reach the earth?

    If the sun were to disappear, could we literally see the sun’s same brilliant circular image
    (that actually isn’t there anymore) for about the next eight minutes? or would it continue
    to provide light, without actually projecting its illuminating presence in the sky? or would
    the sky we see on earth lose its light immediately?

    <div class=””>I see gravity as a push rather than a pull. If you are standing on a planet, you feel gravity because of the push of “ether” coming from above you. You are shielded from this ether pressure below you by the mass of the planet. If you could journey to the center of the earth you would be in zero G. (You will be shielded by equal mass all around you). The big question is how can one prove it is a push and not a pull? Newton only said it’s an “apparent” pull but he did not say this was the real way it worked. I think push is more parsimonious because how do you explain something that pulls without touching and at huge distances? It’s much easier to envisage something pushing against something else to cause pressure or movement (like gas law).

      Gravity can’t be a ‘push’ but a pull because gravity is electric in nature and hence it’s an attraction. If gravity is a push, then is electric attraction also a push?

    Hi Laura. I tried to view the images there, yet without luck! Were you responding to my previous post there in particular? Considering what you have said, isn’t the question of whether gravity pushes or pulls, without a definite conclusion of if gravity “travels” or if it’s “instantaneous”? Does the “maximum possible velocity” apply to gravity, as well as light? Does gravity travel, except slower than c? Also, is it a constant?

    The thought that gravity is either a push or a pull, to me, seems possibly misleading. Maybe that’s sort of only a guess. What if gravity actually isn’t either of them. I’m also skeptical of the idea that light is a particle or a wave.

    Have you heard of the Dinu effect, of the experiment with the under-water spinning cylinders? It seems to illustrate the effects of magnetism.

    Also, that was quite intriguing, the idea you had that zero gravity exists within the center of the earth. I hadn’t considered that. What about the earth’s orbit around the sun though? To consider that the sun and moon appear from our earthly perspective as around the same size, there was one principle of motion that Newton had expressed for the effect of gravity, as to the size of a given object, and its distance away (or something similar to that.) 🙂

    Anyway, here’s a quote I found online, “The inverse square law proposed by Newton suggests that the force of gravity acting between any two objects is inversely proportional to the square of the separation distance between the object’s centers.”

    Though, that is slightly besides the point. lol

    There’s much I could write about the ether. Would you possibly want to meet over in the ether group? I just thought the ether is possibly too much of an extensive topic to discuss quickly, or maybe I’m just seeming “nit-picky”. lol Whichever way is fine with me though.

    Anyway, thanks for your response!

    To open those images click on them, click download, click open. Or you can see one of the graphs here: https://physics.stackexchange.com/questions/164032/infinity-problem-why-is-gravity-g-0-zero-at-the-center-of-earth-if-according

    I think of ether/gravity as a fluid like substance that exists in all space. Waves can be transmitted through it – pressure waves? So waves that can push. I can’t imagine how something could exert a pull force on something else so this makes sense to me. So gravity doesn’t travel but sloshes in waves or is transmitted by “gravity/ether particles” hitting and bouncing each other like gas particles inside a balloon or water in a lake.

    I don’t think that anybody knows what gravity is but it does exist as we can feel its effects. I also think that it does travel thus it takes time for us to feel the gravity of a distant object. I also believe that gravity travels with the same speed as that of light so that e.g. the gravity of the sun arrives at the same time as its image. Otherwise, we would feel the gravity coming from a different place than from where we ‘see’ the sun.

    Some people have put words in Newton’s mouth that he said that the speed of gravity is instantaneous. This implies that the speed of light (SOL) is also instantaneous which flies in the face of what Newton said about light i.e. that it’s a stream of corpuscles (particles). Now, particles have a finite speed; hence, they cannot be instantaneous. The fact that we feel the sun’s gravity at the same time as we see its image, implies that gravity travels at the SOL. Perhaps that’s what fooled most people into thinking that it’s instantaneous.

    As to what gravity is, I follow the Electric Universe’s (EU’s) model of dipole gravity i.e. that it’s of an electric nature. I have my own theory regarding the Standard Model: there are only 2 fermions (electron and positron) which form all matter; only one force of nature (EM force); and only one boson (photon) which mediates the EM force as well as carrying momentum and energy.

    Then these electrons and positrons form nucleons that interact electromagnetically with each other to form nuclei and eventually atoms and molecules. Because electrons and positrons already exist in the nucleus, there’s no need for the weak nuclear force. Because nucleons interact electromagnetically, there’s no need for the strong nuclear force. Now that the EU are explaining gravity in terms of electricity, it means that the EM force is the only fundamental force of nature. Besides, did you know that Michael Faraday said that he suspects that gravity is due to electricity? This was after he experimentally proved that light is an electromagnetic phenomenon.

      If gravity is electrical then how is that electricity carried through space?

    Hi all.

    Joining this discussion late as it were.

    In summary my opinion on gravity is that it’s instantaneous and attractive.

    Ok what causes it you ask?

    There is a concept in my head but I can’t put it into words. It has to do with an intrinsic property of matter.

    It’s assumed that the antiparticle of the electron has negative gravity. Sabine Hossenfeldter actually did her PhD thesis on this but it can’t be proven because the half-life is so brief. Also the mass to velocity ratio is so small that detectors to detect it’s reaction to gravity can’t be constructed.Sabine said in the end it wasn’t logical anyway. I don’t believe gravity is electrical. The electrostatics phenomenon is just too well documented to allow a loophole for gravity.

    I’m going to predict that when a true cause of gravity is discovered then a lot of nonsense in physics will disappear, namely things like the neutrino , dark matter and distance measurement over long distances.

    I was at a conference in Yelm Washington once where a person sat on a force plate in a room where some 30 guests observed a graph of the output of a force plate on which the subject was sitting. The subject concentrated on getting lighter, and they did.

    The weight (force between the subject and the earth) did indeed change over time. I went up afterwards to examine the equipment but I was unable to ascertain the magnitude of the variation. At the time I wrote it off as a hoax. They were members of a cult who also made lots of other unbelievable claims.

    Where I am now I like to think I have an open mind about gravity.

    I read an article yesterday that Einstein went to his grave denying that GR supports the geometrization of gravity. He was also a naysayer of quantum mechanics and spoke about the non existence of black holes.

    I have serious objections to SR because it’s inconsistent and leads to “paradoxes” . Hello folks, a paradox means it’s not true. I wish language was not so imprecise and subject to misapplication.

    Ok , my two cents. See you later.

    Thanks for inviting me to the group.

    I may have to reconsider my position on the propagation speed being instantaneous. Simultaneity has always been hard to grapple with. It involves metaphysics and possibly the occult. Yet there are strange things in the universe. These could account for instantaneous action at a distance. But unlikely.

    Until it’s been shown I must reserve judgement.

    Sorry for being ambiguous.

    Fatio’s model is neutrino-like particles moving in all directions. They are absorbed to a small extent by matter. Therefore, fewer particles are leaving a body in relation to number of arriving particles. So, gravity is not a pushing and not a pulling force but a small difference between a pushing and a pulling force.

    Newton’s model is not complete, since he derived the law by mathematics without observing that the law demands spherical symmetry on the body causing gravity. The model can be completed by splitting up a gravitating body in small volume elements, apply the model to each element and then integrate, so we no longer need spherical symmetry. The model becomes complete and can describe gravity. So, Newton’s model is only an approximation.

    Newton’s completed model can be united with Fatio’s model by assuming matter to absorb ether particles and cause a small attenuation in the flow.

    Newton’s mistake of not observing a mathematical demand means that he did not see that the idea Fatio sent to him could explain gravity by a radial ether wind equal to the escape velocity. Since the ether must contain mass this a natural behavior of ether in relation to other forms of matter.

    With best regards from _________ John-Erik
