Being in a known pkace at an unknown time is more or less the same thing as being in an unknown place at a known time. Think about spacetime as one multidimentional continuum.

Also, as far as I know, many theories _require_ gravity to be [the weakest force](https://www.quantamagazine.org/where-gravity-is-weak-and-naked-singularities-are-verboten-20170620/). So it is not that unexpected.
