    Maybe some day.

    In the interim, a little physics/astronomy: time supposedly slows to a crawl near massive objects, say neutron starts, and comes to a stop, divides by zero, ceases, at black holes.

    My understanding is if time stops the physical universe can’t exist, no change of state, and goes poof. Then God throws down another lightning bolt and says let there be light again, and starts the clock ticking. It fits in with God is eternal, and there is eternal existence, the realm is not detectable by us as it isn’t physical. Physical in any way means there is a change of state.

    More detail than anyone wants is here:

    Gravitational time dilation - Wikipedia

    "To illustrate then, without accounting for the effects of rotation, proximity to Earth's gravitational well will cause a clock on the planet's surface to accumulate around 0.0219 fewer seconds over a period of one year than would a distant observer's clock. In comparison, a clock on the surface of the Sun will accumulate around 66.4 fewer seconds in one year."

    Elsewhere:

    "Global Positioning System (GPS): Satellite clocks run about 45,000 nanoseconds faster per day due to weaker gravity in orbit, requiring built-in corrections for accurate navigation"


    It seems that the best current atomic clocks can detect differences in this gravitational time dilation in Earth's gravity well over a vertical distance of about a foot. But a few years ago, using an effect that was not yet turned into a continuous clock, a group was about to detect this difference over a vertical distance of about a millimeter:
