Geometry has no substance

    I could understand ST being modeled as some computer program where bodies follow
    some imputed mathematical formula, but how does ST as geometry force physical bodies to follow some path?

    Well, string theory describes gravity in the IR, so presumably the answer is the same as in GR.

    At least in this address by Einstein in 1920, he was convinced that geometry existed because of substance:
    I wonder if this may be revisited or if it has been discarded for good in modern physics.

    I was confused... Do you mean ST (string theory?) or SR (special relativity) ?

    This is what i meant but was unable to verbalise with so much eloquence, Einstein has
    once again eclipsed what i imagined was an original thought.
