If the universe is expanding like great minds predict, wouldn't that mean that our very solar system (along with our planet) would have to expand at the same rate? After 4.6 billion years, one might expect that our planet should rip apart. Why doesn't this occur? You'd also expect an increase of radial distance between the planets and the Sun (well I would). Why has this not occurred? I'm not saying that universe expansion does not occur, I just want to know why said phenomena doesn't happen.
