Laws of gravity for a universe that only consists of two objects? Hypothetically, if a theory predicted that in the "fake universe", the two bodies wouldn't feel a different pull if they moved away from each other, that would just mean that the Newton/Einstein theories are approximations of the general laws. That they give most precise results in our part of the universe, with our circumstances. |

Laws of gravity for a universe that only consists of two objects? I just updated my question. Let me know how I can make it more clear. |

Laws of gravity for a universe that only consists of two objects? That's one definition. But is that the consensus? Are there other theories that describe gravity in other ways? Perhaps the second way that I described? |

Is dark matter repulsive to dark matter? Why? Thank you for your clear answer :) So assuming something like our sun is dense enough to pull dark matter towards itself, dark matter would get attracted, but it would pass through the sun because it can't collide with it. What about black holes? Aren't they dense enough to hold dark matter in? And also, if dark matter doesn't radiate as it is falling into a black hole, then large amounts of dark matter would fall into black holes, and that would make the black hole grow too fast, perhaps faster than what we have observed, right? |

Is dark matter repulsive to dark matter? Why? Exactly. But we still need to know why dark matter doesn't form dense objects itself. It has attractive gravity, and there is no electromagnetism to push it's particles apart. |

How come neutrons in a nucleus don't decay? The second answer was more helpful to me but, the first one was concise. I don't understand why the first answer got down voted. Probably something I'm missing. Anyway, I'll accept the second one, just to be safe. But please someone help me understand why the first one is incorrect. |
