Extra-Dimensionality of the New Creation

Two statements at the beginning of Revelation 21 affirm that the new creation exists in dimensions (or their equivalent) entirely independent of the ones we now experience: I saw a new heaven and a new earth, for the first heaven and the first earth had passed away The old order of things has passed away. He who was seated on the throne said, “I am making everything new!”
