Long-period comets and gravity

Maybe comets being flown is a topic for a science fiction story. It seems to me the gravity field is not moving at all and the comet moves through the field. So, gravity doesn't have to move and since it is a force gravity really can't go anywhere anyway.

<br />long-distance comets are somehow dislodged from the dubious Oort cloud in the correct angles and velocities to fall inward to precisely pass around the Sun.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">The EPH, a major topic at the host web site here, is an alternative to the Oort cloud. It says all those comets originated in the explosion of a planet in the inner solar system 3.2 million years ago.

How do the comets counter for that actual, physical misrepresentation as they move inward?<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">At great distances, comets do not feel the Sun's gravity separately from the gravity of the planets. The comets are instead pulled toward the solar system's center of gravity (barycenter), which is a fixed point at one focus of the comet's average elliptical orbit. Only after the comet gets into the planetary region does it begin to transfer to an ellipse with one focus at the current Sun location, an ellipse that is strongly perturbed by the major planets.

<blockquote id="quote"><font size="2" face="Verdana, Arial, Helvetica" id="quote">quote:<hr height="1" noshade id="quote">The simplest explanation is that gravity is far faster than the speed of light.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">Six other experiments show that gravity is faster than the speed of light. (See this host web site.) But you can't prove that by comets. The Sun is displaced from the barycenter mainly by Jupiter and Saturn, but with very long periods (years) compared with the few hours or less it takes light to get to a comet after it has enetred the planetary region. -|Tom|-
