Conventional: The totality of physical existence, which includes stars, planets and galaxies. ACIM: The totality of true existence, true reality, which was created by God and is "beyond the sun and stars" (M-20.6:11), "beyond the petty sum of all the separate bodies you perceive" (T-15.VIII.4:5). It is a virtual synonym for God's creation, the sum total of what He created, in that it can refer to the Sonship in its heavenly state or in its separated state.
