Fable: There is such a thing, but it only occurs where births outnumber deaths in an almost-empty area. In a way, by seeing the red shift as the galaxies fly apart, we are witnessing antigravity. And we conceive of a future possibility: We can't control the decay of radium, but the decay sends out radiation we can control; we can shield the radiation, deflect it, and narrow it. We can't control the birth and death rates, but perhaps we can control the pulse of gravity once it's sent out.
Current view: Now I'm interested.
The idea of matter and space going out of existence together explains gravity quite well.
CAN WE EXPLAIN GALAXIES AND STARS
Why do most galaxies look like fireworks pinwheels, and why do galaxies and stars spin?
Let's talk about galaxies.
First, where do the arms come from?
Panel 1: Four galaxies exist. The little dots are nits coming into existence and spread out quite evenly since they randomly appear. As soon as a nit shows up, it feels a pull of gravity from the galaxies. Since the nit is about a million light-years away from any galaxy (on average) you can imagine how weak the force is. The nit barely drifts towards the nearest galaxy; many of them will fall in a direction that's a combination of the pulls from two or more galaxies, like valleys.
