# ZetaTalk: Galaxies Note: written during the 2001 sci.astro debates.

The Repulsion Force is what keeps suns apart, at the distance they are, or at least is a factor in this. The reach of the force of gravity is immense, as with the distance that light particles travel, but like light particles gravity particles on the move can be deflected. Light particles reaching man from across the galaxies has moved in essentially a straight path, unless being deflected or absorbed by something in its path. What is the drama that occurs when more than two gravity giants are in a vicinity, and why is it that binary suns are so common?

• Gravity particles with a single gravitational giant in the vicinity float into the giant and spurt out, without conflict. At the end of a spurt, their desire to clump with their kind causes them to return to the nearest clump. This could be equated to light escaping from a Black Hole, where it is on the move but not leaving, rather returning. The fact that other gravity particles in the vicinity are returning is no small part in this, as those in the flow are attracted to one another also, so the particles at the end of a spurt find they also are moving toward the gravitational giant as a result of trying to move to gravity particles nearby.
• When there are two gravitational giants of equal size, as in binary suns, the drama is joined by a dither point between the two. Gravity particles at the end of a spurt, or slowing in their exit due to reduced pressure as dissipation occurs, find a mixture of streams going back to both giants at this dither point. Repulsion outbursts are intermittent, so at one time the dither leans more toward one giant where a return flow is ongoing, but at another time the return stream to the other giant is stronger, and a particular gravity particle switches to flow into and out of the other sun. Where the suns are matched in size, they stay apart where the Repulsion Force keeps them, to the extent that their dance is dominated by gravity.
• Gravity particles streaming in an outburst from a giant but not encountering another outburst from a nearby giant can move outward to a great distance. This is dependent upon the force with which they are expelled from the giant, giving them great momentum. At the same time, the single drama of each gravity giant continues, and any binary dance that has developed between balanced suns continues, so the particles escaping the area are those not caught in other dramas. Gravity attraction is a small factor in slowing the escape of matter ejected during a Big Bang, and bringing this together again during a collapse, ultimately into another immense Black Hole. Other subatomic particles are more significant in the dance between galaxies, however. Gravity dances tend to be a local affair.
