Hasn't the Hubble, some years ago, discounted this?  Repeating comet
orbits are not the neat eliptical orbits assumed in the past, but more
fan shaped. Maybe the Hubble didn't spend enough time in school,
studying Newton's laws. Tisk.

    Where orbits are snug about their center of gravity,
    there is little contradiction between these and what
    mankind calls their laws of gravity and motion.
    These are not laws, of course, but elaborate
    descriptions of what they observe. The flaws in the
    laws, however, were always present. If gravity
    diminishes with distance, but distance is attained
    with speed, then an object in a snug elliptical orbit
    seems to logically be adhering to the laws of gravity
    and motion. Speed up during the approach, sling past,
    and the speed carries the body outward where the
    diminishing gravity pull slows the body down so that
    its curve sidewards takes predominance. The theory
    fit what man observed, and thus was not questioned
    until his powers of observation increased. Tiny
    comets, seen by man in the past only when they gave
    their brilliant displays while going around the Sun,
    have only recently been observed in great detail
    during this passage.

    Repeating comets are not slinging past, as in a
    passing body. They are in orbit, doing the better
    part of a circle about the Sun. Unlike the planets,
    whose center of gravity is just that, at the center,
    the comet does not behave as though the Sun is its
    center of gravity. The elliptical orbit of planets
    is such that if one were to examine the distance
    from the Sun, the difference at any given point
    would be slight. It is more circular than not.
    Comets, however, are at the other extreme. They
    appear to be a fan, rather than an eye. For the laws
    of gravity and motion to fit, the comet must be
    increasing its speed as it leaves the Sun, thus
    explaining its increasing distance. However, careful
    studies have shown this not to be the case. The
    comet is going its fastest when closest to the Sun,
    and has slowed down when it begins to leave what
    is assumed to be its gravitational master. The
    slowing precedes the exit, thus throwing the smug
    assumptions of man into consternation.

    In addition, the distance comets travel outward,
    and the curvature of their exit are now able to be
    examined where in the past they were an unknown.
    They go essentially straight away, not the curve
    anticipated. Thus the distance from the Sun
    wherein they would have to complete an elliptical
    curve is extreme, challenging the laws of gravity
    and motion. The distance where the elliptical
    curve would reinstate is too far, and the curve
    during the straight away too slight. Rather than
    deal with this new information, the majority of
    scientists prefer their comfort factor over new
    knowledge. Change is resisted, and for many the
    Earth is still flat.
