Tension of space-time

  1. Aug 26, 2009 #1
    This is not a homework question. I'm 41 and have recently become interested in physics but have no background in the field. My question is this:

    Does General Relativity account for tension in Space-Time?

    That is, when space-time becomes extremely vast, where there is very little matter (mass) would the tension of space-time be so weak that the introduction of the smallest mass, say a helium atom cause a large gravity well (curvature)? And inversely, would the tension of space-time be so great at the quantum level as to not create a gravity well (curvature) at all?

    Another question is, if electromagnetism can be both positive and negative and subatomic particles can have a positive and negative spin (given strong and weak nuclear forces), then why doesn't gravity and General Relativity have an inverse function?

    Or am I a complete dolt... could anti-gravity account for the strange behavior of particle physics or super-tension of space-time?

    Tension? I think you are using a word in a way it normally isn't. Can you maybe explain more what you mean?

    No it's not that way. Many people ask such questions due to the rubber sheet analogy.
    that's why spacetime is hypothetical and the rubber sheet is a real analogy.

    Because there are no two things about gravity, it only attracts.And "inverse function" isn't the correct usage, it is negative
