Our universe exists int he planar present as now expressed, and entire of creation exists in the volume of time. There are strong clues that the limits we endure are not a hindrance to certain beings, like Jesus who left the tomb without rolling away a heavy stone and entered a closed room without using a door or window, just materialized there and vanished from there. [Also, see fifth chapter of Daniel, for another interesting hint at the 'volume of time' and a being who reached from that where/when into the where/when of a Babylonian king and his party animals.]
