We know of course that Mary’s body was assumed into heaven.
We know that the human body requires certain environmental conditions to survive (e.g., oxygen, moderate temperatures, etc.).
So Mary’s body has to be somewhere that supports human life.
Location is defined by coordinates (i.e., xyz/GPS) plus time.
So is Mary’s body on earth somewhere in our future - since she is outside of time now in eternity?
I realize there is no definitive teaching on this matter, but this question could be fun to conjecture about.
