A super n00b gravity question

  1. Jul 31, 2008 #1
    I know nothing about physics really, but I get on kicks that I can't stop wondering about, most of which are nothing short of silly I'm sure. Well here's one that I would love someone's indulgence in a response to:
    I am a FIRM believer in equal and opposite, I think no matter what we learn about anything that will be rule #1, or close to it. That being said, I think they say just after the big bang the universe was out of balance where heavier particles attracted others and so on, or that the Higgs boson they are using the LHC to look for that was so heavy it fell apart to create stuff that would attract and so on. Again, I don't know if I'm still making sense, but, by any means if things came apart at the very beginning wouldn't they want to revert to their natural state and come together? Ultimately my main question is, could gravity be the reaction to either the early universe falling apart (being so long ago going towards why gravity is so weak), or to the universal expansion itself? I have read a bit on the idea of gravity "Leaked" out of another dimension, but I don't think so.

    Thanks for your time and patience. :)

    I don't know if gravity is considered a reaction to anything. It's just a force relative to mass, velocity etc.

    As the universe expands and adds space between masses, the force of gravity is naturally weakened (which is what I think you're talking about).
