If a particle really only interacted with gravity, would it pass through matter? AFAIK “touching” things is electron repulsion…
Looking at it from a quantum field perspective, pretty much. If the only interactions are through gravity then the underlying field’s evolution can’t be influenced by anything else, I have no real idea what the implications of that would be because we don’t have a QFT for gravity.
