hi all,(adsbygoogle = window.adsbygoogle || []).push({});

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, im fairly sure that i have only the vaguest handle on the concepts involved here, so im wanting someone to put me out of my misery.

many thanks,

PMF
