hi all,
i have a general interest in the big questions in physics but am no einstein. i am hoping that someone here may take the time to answer what i think maybe a basic flaw in my understanding of these things.
my understanding of einsteins notion of gravity is that a mass bends space-time & its this curvature of space-time that pulls objects in. therefore there is no force as such. objects are following the natural curvature of space-time. its the notion of no force that hit me yesterday. there has been no discovery (yet) of the mysterious graviton despite extensive searching & this would seem to back up the notion i have of no force of gravity. so, is gravity a force?
& if it is not a force then surely attempts to unify gravity & the 3 forces laid out in quantum mechanics would inevitably lead to peculiar results (infinities)? so why is this approach used to infer that general relativity must be wrong?
anyway, I am fairly sure that i have only the vaguest handle on the concepts involved here, so I am wanting someone to put me out of my misery.
many thanks,
PMF
