    Default There Is No Dark Matter

    The law of gravity is expressed as F = Gm1m2/r2. And although it is a constant throughout the universe, the constant appears to change as we view objects extremely far away from us (the observers). This is because space becomes more compressed from our perspective the farther away things are from us, although to an observer on that side of the universe space appears the same there and the law of gravity is precisely the same as it is here. That's why there appears to be some anomalous substance known as Dark Matter. It is only found far away from us, never near by. Because the farther back we look in time (and space), the more compressed time and space are (or appear to be) until they reach the ultimate density known as the Big Bang. Thus the law of gravity appears to change the farther back in time we look because space appears to be more compressed, leading to the effect that things far away are speeding away from us. This speed is made possible by the compression of space and time. It stands to reason that the law of gravity would also appear to be different when viewed from farther away, as gravity is an effect of space and time. Therefore there is no need to speculate about some anomalous Dark Matter.

    This is not unknown in the physics world. In order to maintain a geocentric theory of the solar system, Ptolemaic epicycles were used to explain the eccentric motion of some of the points of light in the sky. This led to a very complex theory about the solar system which turned out to be incorrect. Physicists today are attempting to maintain their cosmological theory which has been contradicted by a few observations such as a discrepancy in the apparent rotation of galaxies. But this discrepancy can be described by merely fine-tuning the gravitational constant. The vast majority of physicists are not willing to mess with their universal constants, but would instead prefer to create their own version of Ptolemaic epicycles with the Dark Matter hypothesis.

    The article states that this theory attempts to account for Dark Matter, but it doesn't say how.

    If the G constant has to increase by a factor of 10 over a distance of the radius of a galaxy (That is what you need to compensate for the observed effect of dark matter) the gravitational distortion would become stupendous over the span of the observable universe, and so would the corresponding necessary ratio of matter to dark matter in the universe. However, the concentration of dark matter we observe is spread evenly across distance scales and the universe's expansion is not slowing, but actually accelerating, so no.

    So are you saying there is Dark Matter?

    If there is zero point energy there should be dark matter.

    Yes, there is dark matter, because the amount of gravitational force observed is greater than the amount we should expect from the amount of observable mass by a fixed ratio. If your theory was correct, the ratio would increase with greater distance, instead of remaining fixed.

    No scientist is saying that Dark Matter exists.

    Also, for a related question, isn't it a bit much to ask that a galaxy's rotation should behave the same as a rotating LP or CD?
